Synopsis
Upper level ridge over the area tonight will shift southeast and weaken Friday and Saturday. Light flow in the lower levels will allow areas of fog and low clouds to form over the interior lowlands in the night and morning hours through Saturday. A front will move through the area Sunday followed by an upper level trough Monday.

Short Term - Tonight Through Sunday
Satellite imagery shows clear skies over most of Western Washington this evening. Fog is beginning to form in the South Puget Sound and along the Hood Canal. Stratus with ceilings below 500 feet moving down the Strait of Georgia has moved over Orcas Island. Many locations are already below freezing at 8 pm/04z with the remainder of the area in the mid and upper 30s.

Offshore flow today helped dry out the lower layer of the air mass enough to dissipate the fog by noon. Temperature dew point spreads are already shrinking over the interior with most locations at 3 degrees or less at 8 pm. The inversion is still in place ( the high at Paradise on Mt. Rainier today was 52, at Hurricane Ridge 51 ). VAD wind profiler from the KATX radar shows light winds up to 3000 feet. Fog will reform over the interior overnight with some places having visibility drop to 1/4 of a mile or less. With temperatures below freezing in spots freezing fog could cause slick roads until mid morning. Plenty of sunshine again Friday afternoon with highs in the mid 40s.

Upper level ridge weakening and shifting off to the southeast Friday into Saturday. Low level flow remaining light Friday night into Saturday morning for one more round of late night and morning fog. Increasing middle and high level clouds Saturday afternoon with the next system approaching the area. The first rain in over a week arriving Saturday night into Sunday.

Will lower the low temps for the next couple of mornings and add a little fog to the forecast Friday night/Saturday morning. No

Long Term - Monday Through Thursday
Previous discussion follows. As the front starts to exit Monday with rain very gradually wrapping up throughout the day, persistent shortwave troughiness may keep the chance for showers in the forecast into the new month. Both operational deterministic models show a persistent wet pattern however ensemble members lean in the opposite direction with the ensemble mean falling pretty close to nil with regards to precip. Given how W WA will fall between an exiting trough and a building Pacific ridge, this high level of uncertainty makes sense, as a minor shift eastward of westward will make the difference between wet or dry conditions. All of this being said, not a whole lot of confidence in the extended at this time for the mid-week time frame. 18

Marine
Fog expected to expand over the interior waters again overnight through early morning. Seas have eased to around 4 or 5 feet over the coastal waters. Winds will become southerly Friday 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.

Hydrology
No river flooding expected in the next 7 days.
