This weekend
Model land is an interesting (and often wrong) place. I think I've made that point plenty, especially in the days leading up to a storm chase.
But the general consensus is pointing to a fairly good storm moving across the eastern prairies on Saturday and Saturday night. There's not enough consensus, however, to go all-out on the details. One model solution takes the major snowfall (15 cm or so) right over Winnipeg. Another takes it farther north and leaves Winnipeg with a couple of hours of snowfall and then a dry slot.
This storm looks to have it all. Well, most of it--warm front precipitation, a heavier burst on the cold front, and deformation zone stuff smacking areas farther north. Phase could be problematic, and the winds, both before and after frontal passage, could be pretty strong.
Whatever happens, it'll be an interesting storm to follow. Bulletins may be issued tomorrow.
