A wild weather week awaits. A cold airmass is moving into the region, dropping early Wednesday temperatures into the teens and barely getting above the freezing mark in the afternoon. A very moist atmospheric river plume of moisture will move in from the west late Wednesday, bringing a good chance of snow Wednesday night, with a possibility of that snow turning to freezing rain by early Thursday morning as the warm plume falls into trapped cold air in the valleys. The precipitation should switch over to all rain by Thursday afternoon, and rain could last until Friday morning, after which it will break up into showers.

Snow levels will vary greatly, starting at the valley floors Wednesday night and rising to above 8,000’ by Friday. There is a Winter Weather Advisory posted for both the mountains and the valleys late Wednesday afternoon until Thursday morning. High elevation snow could be very heavy through Friday, and travel over the passes could be quite challenging starting Wednesday night and continuing until Friday morning.
