High pressure builds in Upper Michigan, presenting a drier, warmer airmass into midweek. Leftover moisture from this past weekend’s rains helps produce patchy areas of dense fog Tuesday morning, where road visibility can drop below a 1/2 mile at times -- use headlight low beams in areas of poor visibility. Fog and clouds looking to clear into the heat of the day for a partly cloudy to mostly sunny Tuesday in the U.P.

Clouds and humidity increase late Thursday as a system travels northward from the central Mississippi Valley, bring rain to the Southern U.P. Friday morning then northward into the afternoon. Rain chances continue Saturday, diminishing in the evening as the system exits Upper Michigan.

Another system arrives from the Northern Plains to bring west-to-east showers Sunday.
