Heavy snow with whiteout conditions into Saturday morning
(1/17/2020) - Saturday is a great day to relax at home during the morning hours.
Heavy snow and wind will cause very slow travel conditions during the morning hours.
Heavy snow moves in after midnight and will start accumulating quick. Wind will be blowing it around as well. East west roads will be particularly vulnerable to drifting.
With gusts near 40 mph, and high rates of accumulation, whiteouts will be possible.
Snow will be heavy at times through midday Saturday, with snowfall rates approaching 1 to 2 inches per hour. Totals will be between 4 to 6 inches for most, with higher amounts toward U.S. 127 and north of Saginaw Bay, and lighter amounts farther south with rain mixing in Saturday afternoon.
Temps on Saturday will be in the lower 30s farther north to the upper 30s closer to I-69.
Winds pick up Friday night out of the southeast at 15 to 25 mph, gusting to 30 mph. Winds on Saturday will be shifting to the south and west at 20 to 30 mph with gusts around 40 mph possible.
On the backside of this system, temps will fall into the lower 20s Saturday night and stay there Sunday. Therefore, any roadway that is wet and untreated will be able to freeze and become icy.
It'll be windy into Sunday morning with winds lightening through Sunday afternoon. Westerly winds will cause lake effect to continue into Sunday, so scattered snow showers will stay in the forecast for the second half of the weekend.
