Well, the consensus seems to have arrived, now that the system is drawing near. Snowfall and even some rain has already begun southeast of Winnipeg, and will begin developping around Winnipeg early this evening. Rain has already begun falling in parts of the city this afternoon ahead of the main area of snow. In fact, as I write this, it is raining lightly outside my window in the south end. Incredible weather today, feels like March. Snow depth has dropped a good 2 or 3 cm today thanks to abundant melting. It may not seem like a lot, but there really wasn't much snow on the ground to start with.
As for the storm, snow has crossed the international border into southeast Manitoba, and it should begin in the city by early evening and really get going by mid evening. Exact accumulations are still uncertain for areas RRV and west, again because of the narrowness of the area of snow. Areas southeast of WPG are pretty much guaranteed to see 10 or more cm of snowfall. Here's a map below that I've prepared showing how much snowfall I am predicting with this system:
As you can see, it is a tough forecast to make since snowfall amounts drop off so rapidly west of the system. If the snow ends up being a little further east than expected, Winnipeg could end up in the 2-5 cm zone, while if the system moves a little farther west, we would end up with closer to 10-15 cm. At the moment I am leaning towards 5-10 cm for the city. It will be a very wet snow, therefore blowing snow should not be a major issue with the strong NW winds expected tomorrow. It should still be quite mild with temperatures just slightly below zero tonight and tomorrow.
Remember that lonely snow shovel? Looks like you'll finally be able to take it out! :P
