MICHIGAN — A line of showers and embedded thunderstorms is pushing across western Lower Michigan early Wednesday morning, bringing steady rain and occasional rumbles of thunder to communities including Grand Rapids, Muskegon, and Kalamazoo, while northern parts of the state continue to see a messy mix of precipitation.
As of 6:02 a.m. on February 18, 2026, radar imagery shows the most organized band of rain stretching north to south along the Lake Michigan shoreline, advancing eastward.
West Michigan Wakes Up to Rain and Thunder
The heaviest rainfall early this morning is concentrated from near Benton Harbor and South Haven northward through Muskegon. Bright yellows and oranges on radar indicate moderate to heavy downpours embedded within the line.
Grand Rapids is seeing steady rainfall with temperatures around 39 degrees. Muskegon sits near 37 degrees, while Kalamazoo is warmer at 44 degrees. Farther south toward the state line, readings climb into the upper 40s. While no severe weather is expected, atmospheric instability is sufficient for a few thunderstorms. Residents across west Michigan should not be surprised to hear brief claps of thunder as the line continues moving inland.
Central Michigan Sees Steady Rain
As the rain progresses east, communities such as Big Rapids (34°), Midland (36°), Lansing (40°), and Owosso (39°) are seeing lighter to moderate rainfall. Temperatures across central Lower Michigan are generally in the mid-30s to near 40 degrees, which keeps precipitation primarily in liquid form. Roads may become wet and slick, particularly during heavier bursts of rain.
