GRAND RAPIDS, Mich. — Colder air and an upper-level disturbance will combine to generate lake-effect showers Thursday and Thursday night that will transition from mostly rain to wet snow after sunset.
Temperatures Thursday morning were twenty degrees colder than similar times Wednesday, after the cold front that brought mild but rainy weather moved out of the region Wednesday night. Highs will run about ten degrees cooler, in the mid-to-upper 40s, Thursday afternoon.
Dry air will cause skies to remain at least partly sunny into the afternoon, before additional cloud cover and showers start to develop as an upper-level disturbance moves into the area. Showers should begin as mainly rain in the afternoon before transitioning to a mix of rain and wet snow in the evening.
Some of the heavier showers may contain enough snow to leave some slushy accumulations of around half an inch on grassy areas; most areas will see little snow, however. The most likely areas for snow will be west of U.S. 131.
Any lake-effect snow showers will taper off by early Friday, with only a few rain showers expected over the weekend. You can check out the full 7 Day Forecast on the Weather page.
