A dry Canadian Prairies frontal system passes over Upper Michigan Wednesday night, bringing a spotty wintry mix to the region, with the main weather impact to the U.P. developing following its exit -- snow chances come in the wake of this first system as an influx of polar air initiates lake effect snow over the north through northwest wind belts. Lake effect snow, blustery north winds can cause slick roads and poor driving visibility from west to east, overnight through Thanksgiving Day.

High pressure builds back in the region briefly late Friday through Saturday until another Canadian Prairies front brushes the region Sunday morning. This restarts the lake effect snow machine over the north through northwest winds belts, with off-and-on rounds of snowfall Sunday through Tuesday.

A frontal system brings mixed rain and snow chances to Upper Michigan late Wednesday.
