A slow moving low pressure system over southwest Saskatchewan is bringing an extensive area of snow across the southern Prairies from the Rockies into southeast SK. This area of snow will be spreading across SW Manitoba this evening and into the Red River valley through the evening and into midnight. Snow will become heavy at times overnight and into early Monday, with 10-15 cm of snow possible by Monday morning south and west of Winnipeg. Snow will continue Monday across southern MB before tapering off Monday night into early Tuesday. Snowfall warnings are in effect for all areas south and west of Winnipeg including Brandon, Portage La Prairie, Carman, Morden, Morris, Emerson, and Steinbach where storm totals of 15 to 25 cm are possible by Tuesday morning.
For Winnipeg, snow is expected to move in by midnight and increase in intensity overnight. About 2-5 cm of snow is possible by the morning commute, so give yourself extra time for the drive in Monday morning. Roads will be getting snow-covered and slippery, especially outside the city. Snow will continue Monday, moderate to heavy at times, with another 5-10 cm likely by the evening commute. So expect a slow commute home as well. Snow will begin to taper off Monday night into Tuesday morning, with another 2 to 5 cm possible before it ends. Storm snowfall totals of 10-15 cm are possible for Winnipeg between midnight tonight and Tuesday morning, with a risk of higher amounts if we get some stronger bands setting up over us. Snowfall warnings may be expanded to include Winnipeg if the storm tracks a little further north than currently forecast. Stay tuned on this developing winter storm system.. (Note: Winnipeg was added to snowfall warning on 5 am Monday morning update)
