Weather Synopsis for Thursday & Wednesday
A plume of warm frontal moisture is aimed into Washington State and southern B.C this morning, pushing copious amounts of moisture into the region along with elevated snow levels. It's raining almost everywhere except Mt. Baker, and even here snow levels should creep up to 6000 ft by late morning. West winds have overwhelmed light offshore gradients, so rain is expected to continue in the Passes.
The warm front will begin to lift north a bit this afternoon, so the heaviest precipitation will largely shut off for the south Washington Cascades, but remained trained into the Olympics and north Cascades. Alpine winds will remain strong out of the SW through Friday morning.
The front should pass through the Cascades in the early morning hours of Friday. Snow levels will lower late Thursday night through Friday, but with the air mass filtering into the region is only slightly cooler, and snow levels will stay in the 3500-4500 range behind the front. Showers will generally be light on Friday, except for the Mt. Baker area where SW post-frontal flow will help locally enhance shower activity.
