Synopsis for the northern and central washington coastal and inland waters - Broad surface ridging will remain centered well offshore with low pressure inland and will result in onshore flow for much of this weekend into early next week. A frontal system looks to traverse the area waters on Tuesday. Additional systems may develop and move through the region late this week.

Area Forecast Discussion National Weather Service Seattle WA 848 PM PDT Sun May 19 2024

SYNOPSIS
An upper level trough will continue to move east out of the region this afternoon. Weak upper level ridging will then nudge into the region for warmer and drier conditions on Monday.
Another trough will drop south into western Washington from British Columbia on Tuesday and Wednesday for a return to cooler and unsettled weather. A brief dry break is possible on Thursday, before cool and unsettled conditions return Friday and persist into the start of the weekend.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/
Forecast remains on track this evening with just a few lingering showers remaining on radar. These will continue to taper this evening. No additional updates, with the remainder of the previous short term discussion following.

Upper level ridging starts to nudge into the area from the NE Pacific. High temperatures across the region this afternoon will generally top out in the upper 50s to low 60s today.

Weak upper level ridging nudging into the area will bring drier and warmer conditions to the region on Monday. Morning stratus and some areas of patchy fog will scatter out for some afternoon sun.
High temperatures will approach seasonal norms - generally topping out in the mid 60s across the interior. Highs along the coast will stay cooler, generally topping out in the upper 50s to low 60s.

The next upper level trough will drop south from British Columbia Tuesday into Wednesday. At the surface, a cold front moving into the region on Tuesday will bring the next chance of more widespread precipitation for western Washington. This system continues to look rather wet for May, with much of the lowlands expected to pick up about a half inch to an inch of rainfall, while the north and central Cascades look to pick up between 1-3 inches into Wednesday. Winds will pick up and remain breezy on Tuesday in the vicinity of the frontal system and temperatures look to fall below seasonal norms. Highs on Tuesday are only expected to reach the mid 50s. Highs on Wednesday will climb a few degrees, but look to remain below seasonal norms - topping out in the upper 50s to low 60s on Wednesday.

LONG TERM /THURSDAY THROUGH SUNDAY/
The weather pattern will remain rather similar heading into the second half of the week - and looks to start with a brief drying trend followed by the return of cooler and showery weather by the weekend. Latest deterministic and ensemble guidance have come into better agreement on upper level ridging over the NE Pacific nudging back into the Pacific Northwest on Thursday. Thursday currently looks to be the warmest and driest day in the long term, with afternoon highs climbing into the low to mid 60s for much of the region. This drier trend looks to remain short-lived, however, as troughing over the Western US regains its hold late in the week and allows for additional systems to move into western Washington. As such, have maintained chances of showers Friday into the weekend for now. 14

AVIATION
North to northwesterly flow aloft with an upper ridge briefly building offshore. Drier conditions this evening will continue through Monday. SKC with VFR mid clouds in some areas this evening, with patchy MVFR cigs along the coast. Cigs will remain SKC to SCT for most of the interior through early tonight. Cigs will begin to lower further along the coast tonight and likely stratus developing into the interior Monday morning with weak onshore flow.
MVFR cigs generally expected with the stratus, however, areas of IFR cigs may be possible. In addition patchy fog or LIFR cigs may occur across the Southwest Interior, particularly near KSHN and KPWT.
Otherwise, VFR SCT/BKN cigs expected in the afternoon, with lingering high end MVFR to low end VFR along the coast. West to northwest winds at the surface will become light tonight, increasing again midday Monday.

KSEA...Mostly clear into tonight with VFR cigs. Stratus may develop late tonight into Monday morning (mainly 12-18z) for MVFR cigs. The potential for IFR cigs remains rather low with probabilities around 10%. Cigs will improve midday Monday with SCT/BKN VFR cigs into the afternoon. W/NW winds this evening will become light S/SW later tonight into Monday. JD

MARINE
Broad high pressure over the NE Pacific will maintain onshore flow across western WA this week. Winds look to pick up this afternoon into tonight, particularly in outermost coastal waters, and potentially into the Strait of Juan de Fuca, where winds could gust up to 25 kt. As such, the Small Craft Advisory continues through tonight. A weak surface ridge will build across the region Monday.
The westerly push down the Strait looks more substantial, with higher probabilities (65-75%) of Small Craft Advisory threshold winds. A frontal system will pass through on Tuesday. Behind the front, northwesterly winds will pick up across the coastal waters.
The active pattern looks to continue into late week with the potential for additional frontal systems to traverse the region.

Seas around 6 ft near shore to 8 ft in the outermost regions. Seas will decrease to around 4 to 6 ft Monday night before increasing to 8 to 12 ft Tuesday into Wednesday. Waves may be steep with 8 seconds being the dominant period through this week.
