Rain will initially develop across the area around midnight and will mix with or change over to all snow. Until pavement temperatures cool any snow will melt on contact with the roads.
A light snow event is expected late tonight through Friday afternoon across the forecast area. Snowfall amounts generally less than 2 inches are forecast and are expected mainly north of Hwy 30. Pavement and surface temps may make it difficult for snow to accumulate on roads thus limiting impacts
Forecast precipitation timing Friday morning
While snowfall amounts are expected to be light tomorrow, less snow doesn’t always mean you are good to go. Remember to slow down and allow extra space between vehicles tomorrow.
