Marine Weather and Tide Forecast for Ruston, WA

SHORT TERM /TONIGHT THROUGH FRIDAY/
Some locations across Western Washington have managed to clear out the fog (along the coast and north of Everett); however some locations along Puget Sound are still experiencing reduced visibilities. High pressure continues to dominate over Western Washington, which will bring another round of morning fog and low clouds Wednesday morning.
across the interior lowlands and coast. A shift in the weather pattern on Thursday as a weak system will move through the area.
Some light showers are possible along the north coast; however the majority of the precipitation (light mountain snow) will be concentrated along the North and Central Cascades. No significant impacts are expected.

A colder and drying trend begins on Friday as high pressure rebuilds over the Pacific Ocean. Patchy fog possible Friday morning. High temperatures will be in the mid to low 40s; low temperatures will be in the 30s.

LONG TERM /SATURDAY THROUGH TUESDAY/
Cold and dry conditions will continue through the weekend and early next week with high pressure building offshore. High temperatures through Monday are expected to be in the low 40s, and low temperatures will be in the low to mid 20s. With a colder airmass in place and temperatures below freezing, fog formation will be limited.

The deterministic NBM hints at the possibility of precipitation returning on Tuesday in the form of light rain/snow showers for the coast and some of the lowlands. Model guidance also hints at some light precipitation returning on Tuesday, but in the form of rain. PoPs on Tuesday range between 20-25%. High temperatures will be in the 40s and low temperatures in the mid to upper 20s.

AVIATION
Northwest to westerly flow remains over western Washington as an upper level ridge moves over the region. Low clouds, with IFR to LIFR cigs, remain in place over the central Puget Sound area and along the Strait of Juan de Fuca, but clear skies have emerged elsewhere. Not expecting much more clearing this afternoon over the central Puget Sound, but expecting ceilings to slowly rise to low-end MVFR by 00Z Wednesday.

Light winds will continue tonight into Wednesday, allowing for ceilings to once again re-develop and drop to LIFR and fog to redevelop by the early morning hours. Clearing will once again be slow but models are trying to hint that clearing may be possible Wednesday afternoon with less upper level cloud cover, but with such light wind at the surface, it is plausible that the central Puget Sound area once again never fully clears out before high clouds fill in ahead of the next system coming in early Thursday.

KSEA...IFR conditions with low stratus over the terminal. Light surface flow will not allow for rapid changes, but expect ceilings to remain IFR, slowly lifting to low-end MVFR this evening. Expect LIFR to return early tomorrow morning with fog and low ceilings.
Clearing will once again be slow, but ceilings may be able to break up faster, with improving conditions as early as around 21-22Z Wednesday. Winds will remain light north/northeasterly, around 4 kt or less through the TAF period.

MARINE
A surface ridge over the coastal waters will shift inland Wednesday night, maintaining weak northeasterly winds. A weak frontal system will move through the region on Thursday morning.
Stronger high pressure will build in its wake on Thursday for stronger northwesterly flow over the coastal waters and an onshore push through the Strait of Juan de Fuca which may prompt additional headlines. Building high pressure over southern British Columbia and east of the Cascades will lead to a return to offshore flow late in the week.

Seas remain around 10 ft through the outer coastal waters through tomorrow afternoon, for which a Small Craft Advisory remains in effect. Seas will likely rise above 10 ft again with the frontal passage Thursday before subsiding this weekend into the beginning of next week.
