A closer look at the Upper Midwest from the Canadian model shows a trend toward mostly rain for the Twin Cities and southern Minnesota Thursday into Friday, with a potential shot of snow as the system sweeps by through Friday night. There may also be a little thunder with this system.

We’re still likely about 72 hours away from the bulk of accumulating snow potential, so the early forecast model snowfall total output still varies widely and is in the low confidence range. But there is a decent chance of wet snow Friday night across parts of Minnesota.
