Residents woke up to bone-chilling temperatures today in the southeast.
"We got a nice blast of Arctic air all the way down through Saskatchewan," explained regional meteorologist John Paul Cragg with Environment Canada. "Also there was a little bit of wind. The winds didn't really die down that much overnight. And with the really cold temperatures, we saw some pretty low windchills."
"In the Estevan area, windchills just around 8:00 this morning got down to -45. It was a very cold night and with the wind, extreme windchills and that looks like it's starting to end soon."
The extreme cold warning ended in Estevan and area earlier this morning.
"We're expecting a high of -20 with windchills being around the -35 mark over the course of the day. As the temperatures warm, it looks like the winds will pick up a little bit and that combination will keep windchills low but it doesn't look like the windchills will be in the -40 range where we start to issue the extreme cold warnings."
However, there does look to be some relief from the bitter cold temperatures in the next few days.
"It's all thanks to a low pressure system that is forecasted to move across the province. With low pressure systems moving across the province, what usually happens is before the low pressure moves through, in advance of it, there are southerly winds that drag in warm air from down in the States or from the Pacific and really warm the temperatures up. Then, often what happens, when the low pressure system passes through, the cold Arctic air returns with northwest winds behind the system which drag down the cold Arctic air form the Northwest Territories."
Temperatures are forecasted to reach 0oC on Wednesday before plunging to -20oC overnight.
"Looks like we're in for a big up and down roller coaster ride in temperatures thanks to the low pressure system that is forecasted to develop Tuesday through Wednesday."
As for precipitation, Environment Canada is forecasting a chance of flurries on Wednesday.
"With this low pressure system, we are forecasting a couple centimeters of snow in the southeast corner of the province. Depending on the track of the low, you could get a little bit more or a little bit less."
