Four things you need to know about Thursday, July 24
Thursday, July 24, 2014, 7:35 AM - Wondering what you missed overnight or what you can expect for the day ahead?
Here's your weather briefing for Thursday, July 24.
Widespread watches and warnings covered much of the country on Wednesday as thunderstorms fired up through the afternoon and evening hours.
1. Thunderstorm risk pushes into Nova Scotia and Newfoundland
After several consecutive days of heat and humidity in Atlantic Canada, a cold front moving southwards Thursday will help to clear the air.
In addition to cooling temperatures however, is the risk for scattered showers and thunderstorms across Nova Scotia and Newfoundland.
2. Sorry Ontario, no heat in the long range
On Tuesday Downtown Toronto officially reached 30.0ºC for just the second time this summer.
Pearson airport topped 30ºC three times during the month of June, but it has not reached that mark yet during the month of July.
"Tuesday’s high came up just short at 29.8ºC, and it is unlikely that we will get close to 30ºC again during the next two weeks," says Weather Network meteorologist Doug Gillham.

According to Gillham, both Thursday and Friday will be pleasant summer days with lots of sunshine and temperatures remaining a couple of degrees below seasonal.
"However, the dry weather will not last for very long into the weekend," Gillham says. "We should see some sun to start the day on Saturday, but clouds will increase during the day with a period of showers and scattered thunderstorms likely during the afternoon or evening."
Into next week, daytime highs will be in the lower 20s across most of southern Ontario, but in cottage country, temperatures will only be in the teens Monday through Wednesday.
3. Heavy rain prompts warnings in parts of Alberta
A low pressure system over Alberta will result in rain showers and thunderstorms through Friday.
"Total rainfall amounts near 50 mm are forecast, however, locally higher amounts may occur with embedded thunderstorms," warns Environment Canada in Thursday morning's statement. "The rain is expected to taper off Friday evening."
Officials say that heavy downpours can cause flash floods and water pooling on roads, so drivers are encouraged to adjust travel plans as necessary.

The thunderstorm risk also continues across parts of the Prairies Thursday with the greatest chance for severe storms across central and southern Saskatchewan and Manitoba.
4. Severe storms bring flooding rain to B.C.
An intense band of thunderstorms moved across the southern regions of B.C. on Wednesday, bringing flooding rains, frequent lightning and power outages in some places.
The storms resulted in sudden heavy downpours and flashing flooding in Kamloops, forcing some drivers to abandon their vehicles.
A rainfall warning was issued for B.C.'s South Peace River early Thursday with up to 50 mm of rain possible through Thursday.
While the moisture is good news for fire crews that have been struggling with wildfires, the drawback is the instability that could spark thunderstorms.
"Many of the large wildfires experienced so far this year have been caused by lightning strikes," says Vettese.
