There's no denying it any longer. Winter weather is closing in across western Canada.
The same system that's bringing rain to British Columbia will have a domino-like effect in southern Alberta. The moist Pacific system will dump heavy snow, and blowing snow, on the foothills, Calgary and Lethbridge as of Monday night.
And an Arctic cold front should drop temperatures by 10 to 20 degrees in the Prairie provinces.
'The winter air is starting to settle in more permanently now. By the middle to the end of the week, it's going to be below seasonal right across the Prairies,' says Dayna Vettese, a meteorologist at The Weather Network.
Temperatures in Alberta will drop off to the low single digits on Monday, and the negative single digits from Tuesday on. By midweek, it could be around -10 C in many parts of the province.
On Tuesday and Wednesday night, it could feel like -20 with the windchill in Calgary and Edmonton.
Saskatchewan and Manitoba will also see dip in temperatures mid-week, but not heavy snow.
