A weak and dry wave will brush by our area on Monday leading to only cloudiness. Another wave in northwest flow should be far more productive forcing snow to begin Tuesday morning, however the absence of cold air will limit the big accumulations during the day. The last shortwave moving through the northwest flow will bring colder air early Wednesday morning, but this time the moisture is limited, though snow showers should will likely continue through the morning. A small shift to the north or south would change the forecast, but currently I expect 4-8” by noon Wednesday before a transient ridge moves over the area bringing some sun for Wednesday aftternoon and a sunny day for Thursday.
Showers will begin again Friday ahead of a much colder and more significant system that is currently forecast to sweep through the area Saturday. Earlier model solutions had this wave beginning a long-lasting pattern shift, but current model runs have the Gulf of Alaska ridge rebuilding and forcing the coldest air to slide to our east.
A cold and snowy weekend will then be followed by warming and drying early in the next workweek as the Gulf of Alaska ridge expands over our area.
