Welcome to Sunday, Motown.

This evening becomes chillier and remains dry. It gets colder overnight with some areas at or below the freezing mark and other communities above freezing. This is a big factor when it comes to whether rain, a mix of rain and snow or snow will fall tomorrow in towns throughout Southeast Michigan. Snow will fall and accumulate where it’s colder. Calmer weather returns mid-week.

Sunday evening will be chilly and breezy. Temperatures will be in the upper 30s and low 40s.

Sunday night becomes cloudy and remains chilly. Overnight lows will be in the low and middle 30s.
