A low pressure system will quickly intensify near the Minnesota/Canadian border Thursday. Cold air being drawn southward on the backside of the storm will cause rain to change to a heavy, wind-blown snow over extreme southeastern Manitoba and into northwestern Ontario on Thursday.
Right now, it appears that the heaviest band of snow will set up just east of Winnipeg during the afternoon and into the early evening on Thursday.
I just drew up this snow accumulation map with the help of our graphics artists. This is for total snowfall through Thursday night. By the way, 15-25 cm is equal to 6-10 inches.
