The region will be between weather events today with cooler temperatures and still some lingering breezes from the recent cold front passage. The next weather system will bring mountain snow to the Cascades starting late tonight with cold air pushing eastward during the day Tuesday across all of the Pacific northwest.

Snow levels will be low Tuesday morning but rising throughout the day. Initially the storm will impact the Cascades with the heaviest snow Tuesday near the Cascade passes where Stevens pass could get 10 inches by Tuesday night. Light morning accumulations in the Okanogan highlands will be also be possible Tuesday morning. As the front moves east expect light valley rain and mountain snow. Along and just past the cold front snow levels begin to fall Tuesday evening bringing a rain/snow mix of showers as far south as Interstate 90 but accumulations will be minor.

Overall it will be a wet and moderately dynamic system but not particularly impactful unless you are traveling across the Cascades Tuesday and Tuesday night. Expect dry but possibly foggy weather by mid-week. We will see a more stable and much drier weather pattern then for Wednesday through the upcoming weekend with temperatures right around 40 degrees.
