Weather Synopsis for Saturday & Sunday
Gusty winds are easing off this morning after a strong front blew through the PNW Friday night. Leftover scattered showers will end this morning with a dry day forecast across the region. High and mid clouds from an incoming frontal system will spread inland this afternoon and pre-frontal precipitation should move in Saturday night. A trough digging south behind the N-S oriented frontal band will split the system on Sunday. Light to moderate precipitation will fall across the region Saturday night and Sunday, except for locally heavier amounts expected over the Olympics and the Mt. Baker area.
Offshore easterly winds will begin this afternoon and increase overnight through the Cascade Passes. Generally windy conditions will develop in the alpine Saturday night and Sunday as the front stalls out over the area.
