It is likely we'll get period of significant upslope flow from Saturday through early Sunday. 3 to 5 inches of accumulation will be possible. Heavy snow will be possible for most areas Saturday night. More specific updates on accumulation will be posted Friday. Meantime, prepare for winter driving conditons and significant snowfall.
