High pressure in the U.P. clears out lake effect snow and the clouds through Friday, but the reprieve from snow is brief as a Canadian Prairies system brings in widespread snow Saturday. Snow amounts from the system range 1-3″ for most areas with 4″ or more in the Keweenaw and eastern counties.
Temperatures trend mainly below seasonal this forecast period, driven by a northwesterly jet stream plummeting from the Interior Plains of Canada -- a conduit of cold that steers clipper systems towards Upper Michigan and keeps snow chances at play the next seven days.
Friday: Mostly sunny to partly cloudy with southwest winds gusting over 25 mph; clouds increase in the evening, with a chance of snow showers west late
Saturday: Mostly cloudy with scattered light to occasionally moderate snow showers; 1″ to 3″ snowfall accumulations possible, with 4″ or more in the Keweenaw and Eastern U.P.; blustery
Sunday: Partly sunny to mostly cloudy with lake effect snow over the northwest and west wind belts
Monday: Mostly cloudy with scattered, light to moderate snow showers; 1″ to 4″ snowfall accumulations possible
