Weather In-Depth Daily Weather News   -   Thursday July 30th 2009
Get out and enjoy Saturday because it appears that it will be the nicest day this weekend, and quite possibly one of the nicest days we have seen this summer. Sunshine is forecast with temperatures around 27 degrees for the Golden Horseshoe with light winds and low humidity. An approaching frontal system will increase clouds Saturday night and into Sunday along with showers and possibly some thunderstorms along and just ahead of the cold front. At this point it doesn't appear that any severe weather will be an issue, but stay tuned to OntarioWeatherSource.com for any changes.

How cool has it been this July.... I will have a breakdown of the July temperature departures and rainfall totals on Monday's edition of Weather In-Depth.

 

 

July has been a rather cool and wet month for Southern Ontario with numerous days with clouds, showers and below seasonal temperatures. Normal values for this time of year for the Golden Horseshoe region are 27 degrees, but we have been hard pressed to get above 25. The last time we saw a 30 degree value was back in the middle of June and that was only for 1 day. Finally, temperatures are beginning to reach seasonal values with the next few days expected to peak at the seasonal mark of 27 degrees across the regions. Sunshine mixing with clouds will dominate, however a disturbance passing by tonight and Friday morning, may give a bit more clouds to areas north of Toronto with a few isolated showers. I can't rule out a passing shower around the low lakes either, but most of the precipitation will be confined to the north of the regions.

Sunshine will dominate on Saturday and mixing with clouds on Sunday giving a very nice long weekend for many.

Looking at next week.... temperatures should be taking a downturn with values getting back to the low 20's for Southern Ontario by mid week and beyond. Current computer model trends are seeing a cooling lasting into mid August at this point as the Jet Stream continues to deliver cooler air from the north to the southern regions of Ontario. All the heat is bottled up on the west coast and even into the Yukon where temperatures as high as 33 degrees were reported yesterday in several centres including the capitol city of Whitehorse.

Speaking of wet summers, our Capitol of Canada has recieved the the highest rainfall on record since record keeping began for the month of July.

Unusually frequent and heavy rainfalls have soaked the national
Capital region this summer..With July so far having been extremely
wet.

  There were 7 days so far this month with rainfalls of 10 mm or
More at the Ottawa airport. Three days were quite wet indeed with
Daily totals of 47.8 mm July 18th.. 40.6 mm on July 24th and a
reinforcing soaker of 47.0 mm yesterday (July 29th).

  The combination of all these soakers has resulted in a total
Rainfall amount of 243.4 mm so far for July..Making this July the
All time wettest month on record at the Ottawa mcdonald-Cartier
international airport weather station. This breaks the previous
monthly record of 224.8 mm set in June 2002.

  Mother nature will provide the national capital area with a little
Rain free break today and tonight..But her very generous moisture
supply this year may add a little more to the rainfall totals on
Friday as isolated showers are possible in the Ottawa Valley in the
afternoon and evening.

  Julys total rainfall is repeated in the table below.

-------------------------------------------------------------
Date            location            event description

July 1-29    Ottawa airport      243.4 mm total rainfall
                                          Highest monthly rainfall
                                          On record

On another note.... if you want to find summer like temperatrures, all you need to do is go out west. British Columbia has been seeing temperatures into the mid 30's over the past number of days and some spots have topped out at 40 degrees. The heat doesn't stop there. Places in the Yukon and Northwest Territories are seeing temps well into the 30's as well, even up to the Arctic coast where Inuvik had a high of 29 degrees yesterday. These temperatures are expected to continue for the next few days with several centres topping the 40 degree mark in the interior of British Columbia. Now that is without the humidity. It's fairly dry, so there is not much added to the temperatures.

Vancouver and Victoria are experiencing low 30's which rarely occurs for those cities. Perhaps once every 4 or 5 years.

This is caused by a strong ridge of high pressure that has caused to the Jet stream to rise VERY far north as you can see by the graphic on the left.

 

 

Yesterday's Reported High and Low Temperatures across Canada...

 
Weather In-Depth Daily Weather News   -   Wednesday July 29th 2009     (updated by noon each day)
A very moist low pressure system will bring showers and some scattered thunderstorms to the Golden Horseshoe regions today. Most of the shower activity appears that it will be confined to the Niagara regions extending westwards to almost the Hamilton area and then northeastwards to the northern shores of Lake Ontario. There will be some spotty showers elsewhere, but the main area of precipitation will be in the areas I mentioned above.

Environment Canada has issued a Severe Thunderstorm Watch for some areas of Southern Ontario and this is because of the slow moving nature of the storms, so heavy rain is the main threat.

The low pressure system responsible for the clouds and showers today will move out of the regions by early this evening with clearing skies shortly thereafter.

 

 

Temperatures will be below seasonal today in the low 20's across the board but will rebound nicely for Thursday.

We will be caught between 2 systems on Thursday so some sunshine will be seen before clouds increase during the day and the next frontal system approaches bringing more showers and scattered storms for Friday. Temperatures on Thursday will make it to more seasonal values of 25-27 degrees across most of Southern Ontario and up into cottage country.

Looking ahead to the weekend, Saturday appears to be the day to get out and do whatever you like to do. Sunshine mixing with clouds and seasonal temps are expected. Increasing instability will cause some showers or thunderstorms to develop during the days on Sunday and Monday, however temperatures will still be in the seasonal range. A cooler brand of air will make it's way into Southern Ontario for Tuesday and much of next week.

Yesterday's Reported High and Low Temperatures across Canada...

Tuesday July 28 2009    -     Weather News
Weather News is updated by noon each day and as needed throughout the day.
Unsettled conditions will be the rule over Southern Ontario today, however most of the precipitation will be confined to north and east of the GTA. Variable clouds with scattered showers and isolated thunderstorms are likely in these regions. For most of the rest of Southern Ontario, just variable skies can be expected with the ODD sprinkle from time to time.

 

A surge of moisture will take over the regions Tuesday night and into Wednesday with numerous showers and thunderstorms likely. Very humid air will likely spark a few severe storms from time to time. Keep you eyes on the Warnings graphic on the left side for watches or warnings that may be issued in your area.

Here is a look at yesterday's reported High and Low temperatures across Canada.

Rainfall Totals as of 11am; Special Wx Statement dropped
Steady Rain across the Golden Horseshoe today.
Unsettled conditions continue into the weekend.

Some Rainfall Totals as of 11am from Environment Canada
The area of heavy rain associated with a low pressure system has now 
moved out of southwestern Ontario and is affecting regions from 
western Lake Ontario northward to Georgian Bay and eastward to 
Trenton and Bancroft.  This heavy rain will continue to March 
steadily northward affecting regions from east of Georgian Bay to
The Ottawa Valley this afternoon. In general the rainfall amounts 
with this system have been less than expected and this is in part
Due to the absence of thunderstorms which were forecast to increase 
the amounts from those observed. Reports of rainfall within this 
heavy band have ranged from 15 to 30 mm with the highest amounts 
occurring in the Niagara Peninsula.

Given the lesser amounts with this system it is not anticipated a 
rainfall warning will be required and hence this special weather 
statement has been ended.  A summary of rainfall amounts up to 11 AM 
this morning is given below and a AWCN11 CWTO storm summary
Bulletin may be issued this afternoon to update rainfall totals as 
they become available.

Steady Rain Across the Golden Horseshoe Today

A slow moving low pressure system is responsible for the large area of steady rain that has engulfed Southern Ontario. The slow moving nature of this system will give 20-30mm of rain to the regions around the Golden Horseshoe today, however some embedded thunderstorms will give upwards of 50mm to some locales. There are no warnings issued as of 9am this morning, however Environment Canada has issued a special weather statement regarding the heavy rainfall across Southern Ontario.

Temperatrures will be on the cool side with moderate easterly winds developing today up to 30km/h. I wouldn't expect that the high will get much above the 20 degree mark, some 7 degrees below the seasonal values for this time of year.

Conditions will remain unsettled for the next few days as this humid airmass hovers over the region. Scattered showers are likely Friday and again Saturday with coolish low 20 temperatures. Some improvement in the temp department can be expected come Sunday as we climb into the mid 20's, but don't expect to see too much sunshine. Cloudy skies will rule Sunday with the chance of some showers still lingering around.

As in past posts... there doesn't appear to be any heatwaves in the foreseeable future, which takes us well into August.

If you are looking for heat, you will have to go west to British Columbia. The southern interior is experiencing temperatures into the mid to high 30's and has been for several days.

Here is a look at yesterday's reported High and Low temperatures across Canada.

Special Weather Statement Issued Re: Heavy Rainfall

Special Weather Statement for Heavy Rainfall issued by Environment Canada
Heavy rain overnight and Thursday producing rainfall amounts of 25
To 50 millimetres..

A low pressure system currently over southern Illinois is tracking 
slowly northeastwards towards southern Ontario.  A large area of 
heavy rain associated with this low is forecast to reach areas near 
Lake Erie after midnight and then spread northeastward reaching the 
Golden Horseshoe Thursday morning and regions near Georgian Bay 
Thursday afternoon.  By the time the heavy rain ends most localities 
will have received amounts of 20 to 30 millimetres.  However embedded 
within this heavy rain area there may be a fairly narrow swath of
Rainfall amounts in the 30 to 50 millimetre range..Although the exact 
location of this heavier swath remains uncertain at this time.

Environment Canada continues to monitor the situation and rainfall 
warnings may have to be issued later today or tonight as the exact 
location of the potential heavy rain swath becomes more certain.
The Environment Canada rainfall warning criteria requires 50 
millimetres or more of rain to fall within a 12 hour period.

Rain moving into Southern Ontario this evening; Unsettled conditions  into next week

The easterly flow across Lake Ontario this morning along with an increasingly humid airmass is resulting in extensive fog patches in and around the west end of Lake Ontario. Fog patches will likely burn off as the sun climbs higher in the sky during the morning hours, however temperatures will remain in the cooler side. Take a look at yesterdays reported temperatures above and you can see the Hamilton region was a number of degrees cooler than Toronto, all because of the flow across the Lake.

An area of rain associated with a slow moving Low Pressure system will move into the regions overnight tonight and into Thursday. Currently we can expect anywhere from 15-25mm of rain from this event, so a good soaking nonetheless. The unsettled conditions don't end there. A trough in the jet stream along with colder upper level temperatures will allow for clouds and scattered showers to develop each day throughout the forecast period. Basically you will want to bring an umbrella with you each day for the next number of days just to be on the safe side.

Looking into the longer range... there are still no heat waves in sight. In fact, another very cool airmass is expected to dive into Southern Ontario next week bringing temperatures back to the high teens to low 20's.


Forest Fires and Hot Temperatures in Southern BC

Forest Fires continue to rage near the Kelowna area or British Columbia where thousands of residents were evacuated as flames approached. The fire is currently 80% contained according to officials and some residents are being allowed back into their homes.

Weather conditions in the area have been very dry with very little rainfall and scorching temperatures well into the upper 30's for main days. The hottest temperature was 38.2 degrees in Southern BC yesterday and is so far the highest this year for all of Canada.


Yesterday's Temperatures Extremes Across Canada

 

 

Weather News for Tuesday July 21st 2009 -updated usually by noon each day.
A change in the weather map will also result in a change in the air mass over much of the East this week. The main reason for this change is the presence of a high pressure in the western Atlantic, the old "Bermuda High" that will set up this week. This high pressure system, which is so common in a normal summer, has not set up so far this year. Because of the lack of this high pressure system, humidity levels have been low and comfortable for the most part across the East this summer.
However, there are signs that this week will be different from the start of summer. Clockwise wind flow around the high pressure will cause southwesterly winds up across the East Coast, and this will cause moisture to stream inland from the Atlantic Ocean and Gulf of Mexico. So, those who miss the summer muggies may have a reason to smile this week while those who enjoy the cool, almost fall-like pattern experienced so far will maybe have a frown on their face

 

 

Weather News for Monday July 20th 2009 -updated usually by noon each day.

Sunshine mixing with clouds will be the rule across Southern Ontario today, however there will be enough instability in the upper atmosphere for some widely scattered showers or the odd thunderstorm to develop during the afternoon hours. Again, any precipitation that does develop will be widely scattered so it's almost impossible to predict when and where these showers will form. Check the radar images to see where the precipitation is falling.

The coming week will becoming increasingly humid and unsettled as a warmer flow from the south brings a more humid airmass to the regions. Instability in the upper atmosphere however will aid in the development of showers and isolated thunderstorms each day this week. Showers will develop during the afternoon hours due to daytime heating as the warmer air rises into cooler air aloft and then condenses.

Cooler and unsettled conditions will return for Friday and into the weekend as the jetstream once again dips south of the region allowing cooler air from the north to move southwards.

 

Weather News for Sunday July 19th 2009 -updated usually by noon each day.
It's sounding like a broken record, but cool air remains over Southern Ontario as the jet stream continues to dip to the south of the region bringing an unusual July chill to the regions. Temperatures are normally into the upper 20's, but it's been hard pressed to get higher than the low 20's, and in some cases temperatures have remained below the 20 degree mark.

An upper level low has helped to increase clouds during the daytime hours and spark a few scattered showers and the odd thunderstorm during the afternoon or early evening. This feature will continue to do so today, however to a lesser extent than previous days.

The coming week is looking very unsettled as scattered showers and the chance of a thunderstorm develop each day. It's not a washout situation, however it certainly puts a damper on any plans.


Colder than normal and an early start to the winter for the Great Lakes area is expected.
Forecasting 6 months ahead is not easy and is nowhere close to being exact, however the atmosphere gives clues as to what is likely to occur over a period of time and that is what this forecast is. AccuWeather.com released it's winter outlook today and I would like to share that with you.

The weather pattern that we have experienced in Southern Ontario so far this summer is not one that is normal for the region. It doesn't take a genius to figure that one out. Temperatures have been way below normal and this is thanks to the jet stream.

The jetstream is a fast moving river of air in the upper atmosphere at about 25000 to 30000 feet up and is the dividing line between warmer air to the south, and cooler air to the north. When the jetstream shifts to the south of the area, cooler air is allowed to come southwards and conversely, when the jetstream shifts to the north of the area, warmer air moves north. The jet stream is always moving north and south, however this summer it has persistently remained far south of the region allowing a constant flow of cooler air to dominate.

The pattern is not expected to change as we get into the fall and winter months. This would mean that colder than normal conditions will be felt in Southern Ontario through the fall and most noticeably in the winter months.

Last year, the active storm track quite often found it's way through the great lakes region and this resulted in quite a bit of snow for December and January. The storm track is expected to be further east this year, therefore the bulk of storms will move to the east coast. This will keep Southern Ontario in the cold sector, and miss most of the heavy snows. However, for areas that are proned to Lake Effect precipitation around the shores of Lake Huron and Georgian Bay, an increase in snowsquall activity will be likely.

It's too early to pinpoint temperature departures, however the current pattern in the atmosphere and it's trends have given the clues to the upcoming winter. Several computer models are having similar outputs in there long range as well.

Now it's still only July, so enough about snow and cold. Let's just enjoy what little summer we have.

An area of high pressure will dominate the weather picture today with plenty of sunshine and slightly below seasonal temperatures. But really... who's complaining with 25 degrees, light winds and clear blue skies. Sure, some people would prefer 32 degrees, but personally, today's weather is perfect for me. Don't forget to wear sunscreen if you are spending some time outside. The UV index is 8 or Very High today. It's a common mistake amongst many to think that sunburn corresponds with the temperature, when in fact, it has nothing to do with it. Sunburn has to do with the amount of exposure to UV rays from the sun and can even happen in the winter months, although because the sun is not very strong at that time of year, sunburn takes much longer.

An approaching area of showers and thunderstorms will move into the regions for Wednesday afternoon. Now... some of these storms may have the potential at becoming severe along and just ahead of a cold front moving in from the west. Keep your eyes on the weather warnings graphic just below the forecast boxes at the top. It is updated in real time and will turn yellow or red for your region if a watch or warning is issued.

Cooler weather is expected to continue for the latter half of the work week with sunshine mixing with clouds and temperatures into the low 20's.

A sneak peak at the coming winter of 2009/2010 will be posted tomorrow. AccuWeather.com, the worlds weather authority, will be releasing there winter forecast tomorrow. Now obviously this is 6 months away, however there are certain clues and trends in the atmosphere that aid in the prediction of weather several months into the future.

Sunshine will dominate the weather picture today across Southern Ontario, however temperatures will again be on the cool side. This is sounding like a broken record as this has been the case almost everyday this summer as cool air has ruled. Temperatures will range from 20-23 degrees across the regions. It will be a bit on the windier side today as the pressure gradient tightens between a High pressure system to the west and a Low pressure system near the east coast. Winds will likely be 20-40km/h with occasional gusts to 50.

Sunshine is expected to continue on Tuesday with slightly warmer temperatures. Today and Tuesday will likely be the nicest days this week as a disturbance will move into the areas on Wednesday bringing unsettled conditions with showers and scattered thunderstorms.

Overall, temperatures over the next 15 days are not expected to peak much above the 25 degree mark.

Speaking of cool temperatures, just look at yesterday's temps at the top of news section. The morning low temperatures for Sunday morning were into the single digits. There will likely some lower temperatures than the ones I have reported there for places in low lying areas. Very untypical for July needless to say.

Gorgeous weather will dominate the Southern Ontario region today with slightly below seasonal temperatures, but really... who is complaining about 25 degrees and low humidity. Perfect for the beach of going for a walk.

There will be some fog patches around the west end of Lake Ontario this morning and into the early afternoon. This is caused by the easterly winds blowing across the lake and cooler air being blown inland and condensing over the warmer ground. You can actually see this on the visible sat image on the right and below. NOTE:  fog is diminishing so this won't be visible in the afternoon hours.

 

 

Sunshine will continue on Friday, but a warm surge of air from the American South will boost temperatures up to the upper 20's or even 30 degrees in some cases. Sunshine will again prevail on Friday, however an increase in humidity will also be felt.

An approaching cold front will start to increase the clouds during the evening hours on Friday from west to east and some showers or thunderstorms will likely make an appearance overnight and into Saturday.

Some of the thunderstorms have the potential to become severe as a strong jet stream moving overhead will likely aid in the severity of the storms.

A cooler blast of air will come in behind the front as we once again go to below seasonal values for the start of next week.

INTERNATIONAL WEATHER NEWS..

MUMBAI (AFP) – India's financial and entertainment capital is facing a 30 percent cut in water supplies, despite an overnight deluge of monsoon rains on Wednesday that left some streets and homes flooded.

The civic authorities in Mumbai introduced the reduction on Tuesday as levels ran "precariously low" at the six lakes that supply the city's 18 million population with 3.3 billion litres (872 million US gallons) of water a day.

Like many Indian cities, Mumbai depends on the annual monsoon to replenish water stocks. The rains had been due to arrive on June 8 but only hit the city at the end of last month.

Since then, they have been intermittent. Heavy rainfall overnight Tuesday-Wednesday left many lower-lying areas under water and forced pedestrians to wade shin-deep through muddy water.

Colaba, in south Mumbai, received 73.7 millimetres (2.9 inches) of rain in the 24 hours to 8:30 am (0300 GMT), according to the Indian Meteorological Department.

Brihanmumbai Municipal Corporation (BMC) official Anil Diggikar was quoted as saying by the Press Trust of India news agency: "We are facing a shortage of 250 million litres of water per day."

He said the one lake with higher levels can only supply the eastern suburbs, hitting the more prosperous southern and western parts of the metropolis.

Deputy municipal commissioner Pramod Charankar told the Times of India that there was currently enough water only for the next 20 days in those areas unless the monsoon picked up.


Just a reminder if you are one of those beach bums, like myself, don't be fooled by a partly cloudy day or sitting in the shade. Sunburn can still occur as UV radiation reflects from many sources at the beach.

Where has the summer gone. That is the questions that most are asking as temperatures have been very UN-summerlike over the past number of weeks. Just look at the reported temperatures yesterday in the chart above. only high teens to low 20's. Normally we should be into the upper 20's with occasional bouts into the 30's.

 

 

 

 

The JETSTREAM.. the culprit in this cool weather, continues to dip unsually far south for this time of year and has allow cooler air from the north to dive southwards and block warm air from the south from making it's way into the region.

There is no real change expected in this pattern over the next 2 weeks, infact longer range climate models are not seeing a change for most of the summer.

There will be some days of warmer weather with temperatures into the high 20's, but all in all, the average will be much below normal.

Southern Ontario will see plenty of sunshine mixing with clouds today. However... some scattered showers will likely develop during the afternoon hours due to daytime heating and slight instability in the atmosphere. There is also the chance of some isolated thunderstorms. Precipitation will likely be confined to areas north and east of the Toronto area, but that's not to say that a stray shower won't pop up elsewhere.

Cool air remains over the region with daytime temperatures still 3-5 degrees below the normal values for this time of year. Generally Southern Ontario see's temperatures into the upper 20's during July, however we have been hard pressed to get above 25 for some time now.

There will be a warming trend by later in the week, however that will only be kyboshed by the weekend as cooler air is forecast to return at that point and into next week.

INTERNATIONAL WEATHER NEWS..

BEIJING – Floods blocked roads in southern China, leaving some 300 teenagers stranded at a school with limited supplies of food and water, an official said Sunday, after days of heavy rain killed at least 15 people.

About 550,000 people have fled their homes in southern China after heavy rains toppled houses, flooded roads and damaged a dam, news reports said.

Flood waters blocked the entrances to the Hemu Town Middle School in the Guangxi region and rendered nearby roads impassable, according to an official of Rongshui county where the school is. She would only give her surname, Lu.

CCTV said Sunday that floodwaters along a major commercial thoroughfare elsewhere in Rongshui were more than eight feet (2.5 meters) deep. The report said it was the highest water level the county has seen in a decade.

Flood control officials used boats to deliver food, mineral water and other supplies to the school on Saturday, including pumps to lower the water level, Lu said.

She said she did not know how long the children, aged from 13 to 15 years, had been stuck in the building.

By Friday, 80 percent of the county was inundated, causing the Rongjiang river to overflow its banks and forcing the relocation of more than 70,000 people, Lu said.

Heavy rains have battered the region since Wednesday, forcing about 290,000 people in Guangxi to relocate, the official Xinhua News Agency said. The rains began to subside in parts of Guangxi on Sunday, but river levels remained high, the report said.

CCTV showed flooded Rongshui streets, where the signboards of restaurants and shops were all that could be seen above the water. Mattresses, household items and other debris drifted in the water, passing residents on wooden rowboats as people peered out from second-floor balconies and windows.

The county government estimated the damage at 210 million yuan ($31 million), Xinhua said.

The rain also destroyed a 44-foot (13-meter) section of a dike near the base of the Kama Reservoir in Guangxi, Xinhua said.

About 15,000 people who lived downstream from the dam were moved to safety and were now living in more than 1,000 tents, the national flood control office said in a statement Saturday.

In Hunan province, floods have killed eight people and forced 140,000 to relocate. Five people have died in southeastern Fujian province, two others were missing, and 22,000 people have been evacuated, Xinhua said Saturday.

Another two people died and three were missing in Jiangxi province. Another 100,000 people were forced from their homes.

Sunshine returns for the weekend... still cool however.

Temperatures are remaining on the cool side today as they have been over the past several days. Normal values for this time of year are about 27 to 28 degrees, but as you can see from yesterdays reported temps above, Southern Ontario wasn't anywhere near that. And the same will go for today. A mixture of sun and clouds around the Golden Horseshoe and north into Barrie and Cottage Country with high's only reaching about 20 -22 degrees, more like the end of May.

Sunshine will continue across Southern Ontario on Sunday with closer to seasonal values in and around the mid 20's. The only exception will be extreme southwestern Ontario where more clouds than sun will be likely as a disturbance passing by to the south will just skirt by the Windsor/Sarnia regions.

 

Im sure you have heard of the term, "The Dog Days of Summer", but have you ever wondered exactly what that meant and the origins of the term. The graphic below explains.

Upper Level Low begins to move to the east... Sunshine returns for the weekend, but below seasonal.

Actual Reported Temperatures for Yesterday -     Thursday July 2nd 2009

Data is from Environment Canada

There is some light at the end of the tunnel as the upper level low that has plagued the region for the better part of this week is beginning to weaken and move off to the east. Some residual clouds will be left behind today with the ODD shower popping up. Any precipitation that does fall will likely be confined to north and east of Toronto.

Temperatures across the Golden Horseshoe and for all of Southern Ontario for that matter will continue to be 5-8 degrees below the seasonal norms. Normally at this time of year, temperatures should be around 27-28 degrees across the board, but only low 20's will be common place today.

 

 

Sunshine is expected to return to the areas on Saturday as a wedge of drier air makes it's way into the regions. Even with the sunshine, temperatures will still find it hard pressed to get much higher than 22-24 degrees, perfect if you don't like the heat and humidity, but for beach goers... it's rather chilly.

Sunshine will continue on Sunday, however some scattered showers will begin to enter into the picture into the later afternoon hours. Cool air continues on Sunday, and especially on Monday with temperatures only making it to the high teens.

Long range model trends are continuing to see below seasonal values for most of July with higher than normal precipitation expected across the Great Lakes area.

Weather News for Wednesday July 2nd 2009

Unsettled weather continues today, but sunshine returns for the weekend and beyond. Remaining below seasonal.

The upper level low that has plaqued the region over the past few days with numerous showers and scattered thunderstorms is begining to weaken and move off to the east. There will still be some showers and possibly some thunderstorms in the later afternoon today, however they will more be confined to areas east of Toronto. That's not to say that one or two may pop up elsewhere, but the main area of instability is more to the east of the Golden Horseshoe region.

Temperatures will continue to be on the cool side today with high's only reaching the low 20's. Some 5-8 degrees below normal values for this time of year.

 

 

As the upper level low moves to the east, sunshine will return to the areas on Friday and into the weekend making for an absolutely gorgeous 5 or 6 days ahead. Now.. it will be cool so it's not exactly beach weather, however the sun is very strong so 21 degrees under the sun will feel much warmer.

Sunshine is expected to continue into much of next week with temperatures in the low to mid 20's.

Looking at longer range trends... below seasonal values can be expected into the middle of July with near normal temperatures expected for the latter half of the month. There is also expected to be a higher than normal frequency of thunderstorms across the region during July.according to the latest computer analysis

Upper Level Low Responsible for Unsettled Weather

A cool pocket of air aloft or in the upper atmoshpere is responsible for the unsettled weather that we have been experiencing over Southern Ontario the past few days. The ground levels are warm (relatively speaking) and as the warm air rises from daytime heating, it enters into the cool layer above and clouds begin to form and eventually precipitation.

The upper level feature is beginning to weaken so there will be less chance of showers or thunderstorms today, however temperatures will remain on the cool side especially for the first day of July.

There is light at the end of the tunnel however. The upper level low, the culprit in all of this, will move off to the east by the weekend and sunshine will return with pleasantly cool temperatures to Southern Ontario.

 


Special Weather Statement for Southern Ontario

The cold low with its unsettled weather is moving very slowly and
As a result another round of showers and occasional thunderstorms is 
expected this afternoon and evening for eastern Ontario and a large 
part of southern Ontario.

 Some of the thunderstorms will once again contain heavy downpours 
causing reduced visibility and dumping local rainfall amounts of 20 
to 40 mm in a couple hours or less. Pea to 1 cm hail along with wind 
gusts to 70 km/h are also potential features to deal with.

  Conditions also remain favourable for the development of funnel 
clouds this afternoon and evening. These types of funnel clouds can 
form out of thunderstorms or large cumulus clouds and normally do
Not reach the ground.

 However there is a risk that one of these funnels may briefly touch 
down as a weak tornado and become destructive over a very small area. 
Treat all funnel clouds and tornadoes seriously and avoid when
Possible.  Should one develop overhead..Take shelter until it 
dissipates.  Remember that these funnel clouds will normally appear 
with little or no warning.

 As has been the case the past couple days the thunderstorm activity 
will diminish this evening near sunset.

 Motorists should be prepared for local heavy downpours causing 
reduced visibility and difficult driving conditions.
