Beginning Wednesday evening, an arctic front will pass through the Metro Detroit area.
During the night and into the day on Thursday, west/northwest winds will gust between 35 and 45 mph, and wind chill readings will plunge into the single digits by Thursday morning.
The heaviest band of snow appears to arrive between 8 p.m. and 11 p.m. on Wednesday. Snowfall accumulations of 1-2″ will be possible by Thursday morning with lesser amounts closer to the state line and higher amounts in the Thumb and isolated areas that potentially see repeated snow squalls.
A snow squall is an intense, short-lived burst of heavy snowfall that can lead to brief but rapid whiteout conditions.
Depending on how much road crews can clear and treat overnight, I would anticipate lingering slick spots Thursday morning, especially on side roads and elevated surfaces. Otherwise, we dry out later Thursday.
