Temperatures cool as rain pushes into the Prairies
Wednesday, September 18, 2013, 11:26 AM -
After days of extreme and even record breaking heat, temperatures are cooling significantly across the Prairies.
"In places like Calgary, temperatures are dropping by more than 10 degrees," says Elena Lappo, a meteorologist at The Weather Network.
On Tuesday, the city hit 21°C, and the daytime high forecast for Wednesday is a chilly 9°C. That's far below the seasonal value of 17°C for this time of year.
"The plunge in temperatures comes as a result of a low pressure system bringing heavy rain to the southern Prairies," Lappo adds.
Some areas could see between 20-30 mm of rain through Thursday with locally higher amounts possible in thunderstorms.

"The greatest risk for severe thunderstorms will be in southern Manitoba and northwestern Ontario Wednesday night," says Lappo.
The risk will continue through the evening and overnight hours with heavy rain, small hail and powerful wind gusts possible.
Temperatures are expected to rebound to more seasonal conditions on Thursday.
