Major storm system to bring first wintery blast of season across southern and central MB Wednesday night into Thursday...
A pair of strong storm systems over North America will converge into a major storm system over the Manitoba/Ontario border late Wednesday, bringing the first onslaught of wintery weather to much of southern Manitoba Wednesday night into Thursday. This will be the first real taste of winter for many in southern Manitoba after what has been an exceptionally mild fall to this point with little in the way of snow or cold weather. Wednesday will start off cloudy and mild with periods of rain developing in the afternoon ahead of the converging storm systems. Things start to get interesting later Wednesday afternoon into Wednesday evening as the two storm systems begin to converge over NW Ontario producing an increasing NW flow of colder air across southern Manitoba. Rain will change to snow Wednesday evening as temperatures drop below the freezing mark, and continue through Wednesday night into Thursday morning. Strong northwest winds of 50-60 km/h with gusts of 70-90 km/h will produce locally poor visibilities in snow and blowing snow with local power outages possible due to the combination of ice buildup and strong winds. Snowfall amounts for Winnipeg and the RRV are expected to the in the 5 cm range with the bulk of snow falling across central and northern Manitoba, including the interlake and Whiteshell regions where locally heavier bands of lake effect snow are possible. As a result, expect a slower commute Thursday morning as drivers deal with the first snowfall of the season along with subfreezing temperatures and strong winds.
