An Arctic airmass will move into the Prairies this week, ushering in below-seasonal temperatures for the rest of the week.
A cold front pushing through southern Manitoba this morning will bring a bit of snow to the region and mark the start of a much colder temperature regime. A bit of light snow will taper off later this morning, leaving behind mixed skies with a chance of flurries. Winds will pick up out of the northwest to around 30 gusting 50 km/h, ushering in a colder Arctic airmass. As a result, temperatures will hover around -4°C then begin to fall in the late afternoon. The city will continue to see partly cloudy to mixed skies overnight with winds diminishing. A few flurries may be possible if the lake-effect cloud from Lake Manitoba manages to push into the city overnight. Temperatures will drop to a low near -11°C.
Temperatures will struggle to recover on Tuesday. Partly cloudy skies will see increasing cloud later in the day, but winds will stay light throughout. Winnipeg will see a high near -5°C. Some light snow is possible on Tuesday night as another push of cold air builds southwards. Winds will pick up out of the northwest to around 20 km/h overnight as temperatures drop to a low near -9°C.
A large Arctic high will build into the region on Wednesday, bringing brisk northwest winds near 30 km/h. Temperatures will again climb to a high near -5°C with mixed skies and a chance of scattered flurries through the day. The region will continue to see partly cloudy conditions on Wednesday night. Winds will ease and temperatures will dip to a low near -12°C.
