Well, snow amounts with this next storm system are looking rather unimpressive for southern MB as the cold air sweeps in tonight. Models are indicating the bulk of the snow with this storm will track from southwestern SK into central MB (as shown by latest radar) leaving just a few hours of "wrap around" snow for southern MB Monday night. It's possible we may see a couple of cm of snowfall, but I don't expect much more. In fact, some places may just see a dusting of snow as the cold front moves through. The upshot of all this is that blizzard conditions will not be as widespread or as long lasting as they would have been had we received more snow (as earlier expected). As a result, I expect light snow and blowing snow to move into the Red River valley this evening, with near blizzard conditions at times tonight as winds pick up, before things improve by the commute Tuesday morning. Depending on how much new snow falls, there could be blizzard conditions in rural areas for several hours Tuesday morning before things improve by the afternoon or evening. Some road closures are possible outside the city, and rural schools may have bus or class cancellations Tuesday. Conditions in Winnipeg on Tuesday won't be as bad with drifting snow and blowing snow over open areas, but generally good visibilities as the snow will have tapered off by morning. The big story will be the biting cold northwest winds and temperatures in the minus 20s creating windchills of -40 to -45 Tuesday, a big change from the -3 temperatures on Monday.
So in summary, strong winds and much colder temperatures on Tuesday with blowing snow over open areas. Local blizzard conditions Monday night into Tuesday morning, mainly over rural areas. Possible road closures outside the perimeter, with bus or class cancellations possible in rural schools. Minor snowfall storm totals of 2-5 cm. Improving conditions throughout Tuesday. Overall though, things could have been a lot worse with this system (as the GLB model was suggesting a couple of days ago)
