A snowy weather period is in store for Northcentral Washington with area of light snow developing today across most of Eastern Washington. Most of the heavier snow will be confined to the eastern third of Washington and the Idaho Panhandle where 2-4 inches of new snow could fall.
A series of stronger weather systems are expected for Thursday through Friday night, with the potential for heavy snow over the northern valleys and mountains as well as a wintry mix of precipitation for the Columbia Basin and Northcentral Washington. We have a 70% chance of snow in the Wenatchee Valley tomorrow and tomorrow night and goes up to an 80% chance on Friday.
Higher elevations in the mountains of Western and Northern Washington could see between 20 and 40 inches of snow over the next 48 hours prompting winter storm watches and warnings for Stevens, Snoqualmie and Blewett Passes. Obviously, travel in those areas will be hazardous over the next few days. High pressure will arrive by the weekend and remain into early next week, which will bring a drier and colder weather pattern for the start of the New Year.
