High pressure building over Minnesota drives a cool, northerly wind to the U.P. Tuesday night. Drying takes over aloft, but the cool airmass flow over Lake Superior brings an isolated chance of light showers, mainly over the northern counties overnight and into early Wednesday morning.

Partly cloudy to mostly sunny skies into the daytime Wednesday. Then, on Thursday a system from the Ohio River Valley progresses northward and brings rain shower chances to the Eastern U.P.

Rain chances continue Friday and Saturday as a low pressure system sweeps in from the Canadian Prairies.
