A mostly sunny Sunday morning is in store for the Upper Peninsula, but clouds increase from west-to-east into afternoon ahead of an approaching Canadian Prairies frontal system. Chance of rain begins in the Western U.P. in the early evening hours and spreading eastward overnight.

The frontal system is the leading edge of a cold airmass that will keep temperatures below the seasonal in the U.P. during the first half of the week. Rain will transition to mainly widespread snow on Monday. Snow shower chances continue for the NW wind belts Tuesday and Wednesday.

High pressure then builds over the region during the second half of the week, with temperatures trending at or above the seasonal norm.

The next chance for rain and possible snow is expected Saturday with the arrival of another Canadian Prairies frontal system.
