Two winter storms will affect the forecast through this weekend (November 4th and 5th). The first storm will bring light to moderate snow to mainly the mountains and mountain valleys. The second storm system is expected Sunday morning through Sunday night. This winter storm will result in accumulating snow across the entire area including the Columbia Basin, the Palouse, the Wenatchee area and the Waterville Plateau. Motorists are advised to prepare for winter driving conditions. Remember to keep 50-feet back from de-icing/sanding trucks and snow plows.
