A fast-moving storm will move through late tonight into Friday.
Mainly light snow is expected with 1-3 inches likely in the northern & central mountains and a trace to 1 inch in the valleys. With overnight temps dropping below freezing, there might be some slick spots during the Friday morning commute. So I think it's a good idea to get up a few minutes early just in case you need the extra time to get around.
Most of the snow should taper off by Friday afternoon. Mild temps are expected Saturday ahead of the next storm that could bring a better chance of rain & snow late in the weekend.
