Southern Manitoba will see a much more pleasant second half to the work week as an Arctic high pressure system exits the region and allows warmer air to return to the region. Temperatures will moderate and rise to above normal by Friday before a complex weather setup brings showers this weekend.
Southern Manitoba has seen the coldest weather we’ve seen in quite a while. Sunday’s maximum temperature of -0.7°C was the coldest day we’ve had since the mercury topped out at -3.9°C on March 9th. The high pressure system responsible for the cooler temperatures brought a record daily overnight low temperature to Wynyard, SK on Monday morning where the temperature bottomed out at -18.0°C which beat out the old record of -15.6°C set in 1940 (records for Wynyard, SK began in 1940).
With the main ridge axis through the Red River Valley, winds will begin to pick up out of the SE today as warmer air pushes in aloft. This, combined with plenty of sunshine, should allow our temperatures to rebound nicely to around 7°C this afternoon. Warm air will continue to push into our region in advance of an upper low trundling into the northwestern United States and push our daytime high up into the mid-teens for Thursday.
The weather will take a turn on Friday as showers develop overnight Thursday and push into Southern Manitoba Friday morning. Currently it looks like we’ll see just some light showers; remants of nocturnal convection from North Dakota moving along with an area of lift associated with a dying surface low. What actually happens will depend significantly on how the rain develops in North Dakota, so we’ll be sure to keep an eye on that. For now, enjoy the next couple days! Just don’t forget a jacket out there for this morning, it’s chilly!
