It was windy and much cooler today after the rain moved out. Tonight the really cold air will arrive and with it, an upper level atmospheric disturbance that will produce some areas of light snow. Timing suggests the snow will be most likely between 4 am and 9 am tomorrow morning. Only a dusting to one inch is possible. Most areas will be closer to the dusting.

With such warm temperatures recently, roadways are expected to remain wet with snow most visible on grassy surfaces and rooftops. Skies will clear tomorrow afternoon but it will remain unseasonably cold. There will be another chance for a light dusting of snow in some areas Saturday night into Sunday morning.
