High pressure rebuilds over the Great Lakes region, centered over Northwestern Ontario and steering in cooler and drier air to the Upper Peninsula. Wednesday morning low temperatures trend below seasonal with patchy fog conditions, then dissipating midday as temperatures warm to seasonal averages in the afternoon. Clouds increase ahead of a Northern Plains system, bringing rain chances to the Western U.P. during the evening hours and spreading eastward overnight into Thursday. Light to moderate rainfall is expected with this system with quarter to half-inch rainfall possible in some areas.

High pressure rebounds Friday and brings drier weather briefly until a Canadian Prairies-based system arrives Saturday -- widespread rainfall and isolated thunderstorms possible.

Temperatures gradually trend above average into the weekend.
