Michigan starts the morning under thick clouds and biting cold air. Windshields scrape slowly, and sidewalks feel stiff underfoot. That quiet winter start masks a fast-developing December weather shift set to impact Grand Rapids by Thursday.
According to the National Weather Service, conditions improve briefly Wednesday as sunshine returns. Highs climb into the mid to upper 30s, offering a short break from the cold. Roads remain dry, making travel easier across Kent County and nearby highways.
Changes arrive quickly late Wednesday night. Clouds thicken, and scattered showers develop. By Thursday morning, rain becomes widespread, soaking roads and sidewalks through the afternoon. Temperatures rise near the low 40s, which may feel mild for December but sets up a classic winter problem.
Colder air pushes in Thursday evening. Rain is expected to mix with snow, then change over as temperatures drop into the low 20s. Accumulation appears light, but even minor snowfall can cause trouble when paired with falling temperatures. Any leftover moisture may refreeze quickly.
Drivers should plan ahead. Slow down after sunset, increase following distance, and watch bridges and overpasses first. Flash freezing often occurs this time of year, especially after daytime rain. Visibility could also drop briefly during the changeover.
Friday stays cold and mostly cloudy, with highs near 25. A few snow showers remain possible Friday night, keeping slick spots in play. The weekend trends calmer, though winter firmly holds on. Saturday brings mostly cloudy skies with highs near the upper 30s, while Sunday stays chilly with limited sun.
Meteorologists say this pattern reflects an early winter transition across the Great Lakes. Conditions can change fast, especially with lake-enhanced moisture nearby.
