A winter weather advisory is in effect through 6:00 Thursday evening. Lows will be in the single digits above zero in most locations, though it could drop below zero in the far north. Roads may become slippery in any part of the viewing area, although it will transition to mainly rain in the south. New snow accumulation of less than a half inch possible.
Saturday we see a transition to all rain. Unfortunately, the heaviest rain will occur in spots that already got heavy rain earlier this week.
After a soggy week of weather, skies will clear Sunday. The ground is BEYOND warm after Wednesday but air temperatures will be around freezing.
The map below shows total sleet/snow accumulation for the day Thursday but remember there are two rounds with this bout of winter weather.
Thursday night: Mostly clear, with a low around 21. We've seen this setup a few times this winter and typically our change from a wintry mix to rain doesn't happen quickly.
A mix of freezing rain and snow is possible through the morning rush hour. Turning cooler through the day with temperatures falling into the 40's through the afternoon.
Round #1 moves through quickly early Friday morning.
Saturday: A 50 percent chance of showers before noon. In western MI, officials said a washout from heavy rains may have caused two engines from a freight train to derail near Grand Rapids.
