A Central Plains-based system approaches the Western Great Lakes, bringing widespread showers to the U.P. overnight and into Thursday.

Following the system’s exit, a cold airmass from Canada then migrates south into the U.P. towards end of the week, leading to a chance of freezing overnight temperatures, Lake Superior-effect rain plus a rain/snow mix in the northwest wind belts Friday through Sunday.

The jet stream migrates north of the U.P. late Sunday, leading to warmer than seasonal start to next week.

Thursday: Scattered showers early then gradually clearing from northwest to southeast into the midday hours; partly sunny skies near the Lake Superior shores and mostly sunny south during the afternoon; seasonably cool and blustery with northerly winds gusting over 25 mph at times

>Highs: 40s to Lower 50s (warmer south central)

Friday & Saturday: Mostly cloudy with a chance of lake effect rain showers in the NW wind belts, plus rain & snow mix in higher elevations especially during the overnight hours; seasonably cool
