The cold, unsettled weather pattern will bring a good portion of the area light snow accumulations today. Once the snow starts, it should persist several hours, especially along and north of I-80 where up to a couple inches of accumulation may be seen. Because of the cold temperatures and patchy drifting, some roads will very likely become slippery. Use caution and allow extra time.
