Mild weekend ahead.. but turning snowy and colder Sunday night. Tricky Monday morning commute likely..
After 2 weeks of well below normal temperatures, southern MB will be getting a brief break this weekend with some milder temperatures as a couple of weather systems track across the central Prairies drawing milder air across the south. Southwest winds ahead of the first system today have pushed temperatures well above freezing over snow-free SW Manitoba with Brandon up to +7C this afternoon and +9C in Pierson. A brisk southerly wind over the snow covered Red River valley was keeping temperatures slightly colder in Winnipeg at -2C this afternoon. For Saturday, a weak ridge of high pressure will cross southern MB giving dry weather and light winds, with temperatures above freezing. By Sunday, a storm system will track across southern MB bringing snow through the Interlake and western MB parklands with 10-15 cm possible by Sunday night. As this system tracks east of the RRV later Sunday, winds will shift into the north and draw colder air into Winnipeg and the Red River valley with snow developing. Snow will continue Sunday night into early Monday along with gusty north winds producing local blowing and drifting snow. It's possible we may see 5-10 cm of snow by the Monday morning commute in Winnipeg although there is still considerable uncertainty on snowfall amounts at this point. Regardless, residents should plan for a slow commute to work or school Monday morning due to sharply colder temperatures, gusty north winds giving local blowing and drifting snow, and slippery road conditions.
