Marine Weather and Tide Forecast for Neah Bay, WA

SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/
Partly sunny skies and warm conditions will linger into the evening. A weak front will brush the area tonight, bringing little more than increased cloud cover and slightly cooler temperatures Friday. Rebounding high pressure over the weekend and into early next week will boost temperatures Saturday with widespread Minor HeatRisk. 21

LONG TERM /SUNDAY THROUGH THURSDAY/
Sunday and Monday continue to look to be the warmest days with areas of Moderate HeatRisk particularly over parts of eastern Grays Harbor County inland through Mason County to much of the interior south of Puget Sound. As is typical many of the Cascade Valleys will also likely see Moderate HeatRisk values as well with temperatures in the low 80s. Moderate HeatRisk impacts include those sensitive to the heat and who may be without adequate cooling. Additionally, though it will be warm outside, it is important to remember that area streams, rivers, lakes and the ocean - including Puget Sound - will still have very cold temperatures - often around 50 degrees or colder. Please be cautious around colder water despite the air temperatures.
Relative humidity also looks to be unseasonably low across western Washington on Sunday. This poses an elevated risk of fire danger primarily among dry grasses or dead and dry vegetation.

Warm temperatures continue into Monday as high pressure moves overhead from the NE Pacific. Onshore flow returns on Tuesday, bringing temperatures down, but still warmer than normal and dry through the remainder of the week.

AVIATION
High pressure, with dry and stable conditions across western WA will give way to a weak system overnight with increasing high clouds. Low level marine clouds may clip the coast early Friday morning resulting in MVFR conditions for HQM while remaining terminals expected to remain VFR. Flow aloft will remain southwesterly into Friday while surface winds generally northerly with some shifts to the NE and NW.

KSEA...VFR conditions for the TAF period with increasing high clouds overnight. Winds remaining north to northeasterly north-northeast at 5-7 kts.

MARINE
A weak frontal system over the northeastern Pacific will approach the coastal waters tonight into Friday and dissipate.
Onshore flow will increase across portions of the Strait of Juan de Fuca this evening, but otherwise do not expect many sensible weather impacts to the area waters from this system. Seas over the coastal waters will be steep at times tonight into Friday, with the dominant wave group primarily persisting at 5-7 ft at around 5-6 seconds. These conditions have resulted in SCAs for the coastal waters and eastern and central portions of the Strait. Winds in the Strait do not look to materialize until later tonight, so that headline looks to remain in good shape. Will continue to monitor seas for the coastal headlines as latest buoy obs not showing the anticipated chop. Will leave current headlines in place for now.

High pressure will then rebuild over the northeastern Pacific Friday and remain situated over the region through the weekend with lower pressure inland. Additional rounds of westerly small craft winds will be possible Friday night into Saturday along the central and eastern Strait of Juan de Fuca, with latest HRRR probabilistic guidance indicating a 50-60 percent chance of gusts exceeding 21 kt. Periods of offshore flow are likely to develop over the weekend, with winds turning more north/northeasterly across the interior waters. Additional rounds of westerly pushes are possible along the Strait early next week as onshore flow returns to the region.

Seas will hover between 5-8 ft through Friday and into the weekend, possibly increasing towards 9-10 ft at times Sunday into Monday.
