Temperatures will be on the way down this afternoon into tonight and Monday over southern MB as northwest winds start to pick up behind a large storm system over Wisconsin. The bulk of the snow from this storm system has ended over southern MB, however an additional 2-5 cm of new snow is possible tonight into Monday morning as cold air deepens over the area. Strong northwest winds increasing to 50 gusting 70 km/h overnight into Monday will combine with the additional snowfall to give poor visibilities in blowing snow over open areas. In addition, temperatures dropping into the mid minus teens by Monday morning will freeze up any standing water or slush from Saturday's wet snow, producing icy conditions on area roadways and bridges. This will make for poor travelling conditions tonight and Monday across southern MB, especially for the Monday morning commute.. so caution is advised if driving especially on highways outside Winnipeg. Consult MB highways for the latest road conditions across southern MB.
UPDATE: 3:30 pm Sunday: Blizzard warning issued for Red River valley including the city of Winnipeg. Strong northwest winds combining with a developing area of fresh snow tonight will produce visibilities below 1 km across the RRV overnight into Monday. Worst conditions will be in exposed rural areas outside the city. Stay tuned..
