The Inland Northwest will see limited snow shower or flurry chances this week meaning not much of a chance for a white Christmas for most of Northcentral Washington. In the big picture, Western North America is in a split flow under a broad trough of low pressure. Expect patchy fog until noon then partly cloudy skies with mild temperatures with afternoon highs today in the mid to upper 30’s.

A weak weather system pushes onto the coast on Christmas Day Wednesday but it appears to stretch and weaken in the aforementioned split flow, leaving only limited snow shower chances mainly near the Cascade crest. There could also be some lingering flurries over the northern mountains and northern Columbia Basin, but the chance is too limited to include in the forecast. Otherwise areas of low clouds and patchy fog and freezing fog will be in the weather forecast for Christmas with Wenatchee Valley high temperatures tomorrow cooling off into the lower to mid-30’s.

Medium range weather models continue to keep the Inland Northwest void of any major storm systems until this weekend. So, for Thursday and Friday, expect mostly sunny to partly cloudy skies with afternoon high temperatures in the lower to mid-30’s.

A weak weather system slides down in the northwest flow ahead of a ridge of high pressure building into the region Saturday and Sunday with a 20% chance of rain mixed with snow each day and high temperatures in the mid 30’s.

Partly cloudy skies for Monday with afternoon high temperatures in the mid to upper 30’s.
