325am PST Fri Jan 28 2022
Upper level ridge over the area will shift southeast and weaken on Saturday. A front will move through the area Saturday night and Sunday for a return of rain and mountain snow. Wet weather will continue through early next week. High pressure may bring another break in the weather toward the latter half of the week.
Short Term - Today through Sunday
Western WA remains under high pressure with stagnant conditions due to light winds and very poor mixing. Temperatures are noticeably cooler this morning with most sites in the 20s. Fog coverage is less and mainly over the sound but will likely expand through the morning (although still not as extensive as the past few previous mornings). Low clouds and/or fog will be shallow and we should see afternoon sunbreaks once again.
The ridge begins to flatten and weaken as we move into the weekend. Saturday still looks dry but we will see increasing mid/high clouds through the day with a frontal system approaching. Rain then returns Saturday night as this frontal system drags through western WA. Wet weather continues into Sunday with a trailing upper level trough. This pattern change brings more snow in the mountains, including the Cascade passes. 33
Long Term - Monday Through Thursday
We'll remain under moist N/NW flow into early next week for additional rain and mountain snow showers. High pressure (centered offshore) may shift inland again mid/late week for another break in the weather. 33
Fog expected to linger in places over the interior waters again through early morning. A drier airmass has prevented widespread fog as seen over the last few days. Seas have eased to around 4 or 5 feet over the coastal waters. Winds will become southerly today and especially Saturday with the ridge weakening and the next front approaching, but are likely to remain below advisory criteria until the post-frontal westerlies arrive on Sunday. Seas will build behind the front, approaching 10 to 12 feet early next week.
No river flooding expected in the next 7 days.
