PRAIRIES – Arctic Air Risk: HIGH
Alberta gets clipped in the east, but Saskatchewan and Manitoba take a direct hit beginning early Thursday.
By Friday morning, parts of eastern Saskatchewan and Manitoba plunge into the -40s, with daytime highs stuck in the -30s.
Context:
Estevan, Sask., has only recorded three daytime highs below -30°C since 2000 (most recently Jan. 13, 2024).
Yorkton, Sask., has five such days.
Brandon, Man., has only two days below –30°C since 2000–last on Dec. 30, 2017.
By Saturday, the core of the lobe shifts east, but the cold doesn’t loosen its grip.
