Marine Weather and Tide Forecast for Kingston, WA

SHORT TERM /TODAY THROUGH MONDAY/
Satellite imagery shows upper level ridge offshore. Outside of some stratus coming down the Strait of Georgia into the San Juan Islands skies are clear across the area. Temperatures at 3 am/11z were in the 20s and lower 30s.

Upper level ridge remaining in place offshore today giving Western Washington sunny skies. Could see patchy fog develop over the Southwest Interior in the next couple of hours. What little does form will be shallow and dissipate in the morning.
Cold weather advisory until 9 am for portions of the Puget Sound area will remain in effect. Highs in the mid and upper 40s.

Upper level ridge remaining in place offshore tonight keeping skies mostly clear over Western Washington. Ridge starting to weaken Sunday allowing a few high clouds to move over the area in the afternoon. Another cool morning with lows in the 20s.
Coldest locations in the Southwest Interior could get into the upper teens. Another cold weather advisory will be likely for Sunday morning with portions of Southwest Washington and the Southern Hood Canal added to the advisory area. Highs in the lower to mid 40s.

Upper level ridge continuing to weaken Sunday night into Monday with a weak system moving through the ridge into Western Washington Monday. Increasing clouds will be the main story with this system. Chance of rain west of Puget Sound Monday. Cloud cover will result in a little warmer lows Monday morning, in the mid 20s to lower 30s. Highs Monday in the mid 40s.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Extended models in good agreement with the upper level ridge rebuilding and moving inland Monday night and Tuesday. Flow aloft over the Pacific becoming more progressive. With the ridge to the east this will open the door to allow weather systems to reach the area. The first one Tuesday night into Wednesday will be splitting and moving into the backside of the ridge so will only have chance pops Wednesday. Model solutions start to diverge Wednesday night with the operational GFS indicating an atmospheric river moving into British Columbia with Western Washington on the far southern end of the river followed by a front late Friday. The ECMWF doesn't have the atmospheric river solution but does have a front Friday. GFS ensembles have the operational run as a bit of an outlier and are much weaker with the system Friday night versus the operational run. The ECMWF ensembles have a majority of the solutions wet on Friday. Would like to see a few more runs of the consolidated flow aloft offshore before increasing the pops above chance in the latter portions of the extended.
Snow levels will be in the 4000 to 5000 foot range when the possible precipitation arrives so at least starting off this wetter pattern does not look like good snow production in the mountains.

Tuesday morning the last morning with the potential for some areas getting below freezing for lows with mid 30s to lower 40s the rest of the way. Highs a couple of degrees either side of 50 through Thursday then in the lower to mid 50s Friday. Felton

AVIATION
A high-amplitude ridge offshore is maintaining northerly flow aloft across western Washington through the weekend. A small area of LIFR stratus is sitting right over OLM, though this should continue to lift and clear in the next few hours. Elsewhere, VFR conditions with mostly clear skies will continue once again during the day today with increasing high clouds later in the afternoon. There will be another 30-50% probability of seeing low stratus and fog, mainly around the south Sound and Kitsap Peninsula. Probabilities are lower for the Seattle metro. Generally light and variable surface winds this morning, becoming light N/NE winds throughout the day today mostly at 8 kt or less.

KSEA...VFR conditions with clear skies. Winds N/NE around 4-8 kt continuing throughout the day today. There is a 20-25% of IFR stratus between around 15-19Z Sunday, but given the limited expanse today, this will remain a low-probability scenario.

15/62

MARINE
Broad high pressure across the northeast Pacific will remain in place through the weekend with generally calm winds.
The next period of impactful marine weather doesn't look to arrive until Monday, as a weak frontal system approaches the west coast and brings back increasing southerly winds. A stronger frontal system will approach the waters mid-week, bringing a period of breezy southerlies across the coastal waters.

Seas 3 to 5 ft will continue this weekend, increasing to the 8-12 ft range Wednesday and through the remainder of next week as systems move back into the area.
