The National Weather Service has issued a Winter Weather Advisory for southwest Michigan, as overnight drizzle and snow have glazed roadways across the region. The advisory is in effect until 10AM Wednesday.

Road crews are out salting, though the conditions early on have been slippery and may affect the morning commute. Conditions west of Calhoun County are icier, with less snow and more drizzle falling in that area. Still, radar - seen above - shows a wide swath of precipitation as of 5am Wednesday.

The Richard Piet Show on WBCK will have updates on road conditions, weather and any weather-related delays.
