A strong cold front will move through the region during the overnight hours, dropping temperatures 30 degrees lower when compared to Sunday's highs. Rain overnight will mix with and change over to snow showers Monday into Monday night, with daytime high temperatures in the upper 30s along with breezy conditions. This will lead to wind chill readings in the mid to upper 20s. After high temperatures in the 65 to 70 degree range Sunday, this will be an abrupt change.
Some light snow accumulations are possible on unpaved surfaces as the cold front exits the region and lake effect snow showers develop away from the lake, especially across the higher elevations of north central Lower Michigan and along / east of the U.S. 131. Lakeshore areas will be a bit warmer and are not expected to receive as much snow shower activity. Road surface temperatures as of Sunday afternoon were in the 60s. Soil temperatures just below the surface were still holding in the 40s, so the ground is still quite warm.
