The storm setup and timing over the Prairies
Rain, snow, and possible icy precipitation are expected this week, with impacts extending into the weekend. Ahead of the system, temperatures will rise to summer-like highs in the low- to mid-20s near the international border. Behind the storm, daytime highs will drop to sub-freezing for several days.
Due to an atmospheric blocking pattern, the storm will remain over the region into the weekend, delaying its exit. The system is forecast to strengthen again on Thursday, bringing stronger wind gusts and heightened impacts.
Heavy snow spreads across northern Saskatchewan and Manitoba, risk of dangerous whiteouts
Snowfall projections have increased for northern Saskatchewan and Manitoba, with totals of 40-50+ cm possible between Thursday and Saturday. Some uncertainty still remains about the exact location of the heaviest snow in the north.
