SYNOPSIS
Upper level ridge centered offshore nosing into Southern British Columbia today. The ridge will remain in place Friday then begin to weaken Saturday. Low level flow turning offshore today. Offshore flow continuing into Friday with the flow turning onshore Saturday. Weak upper level trough moving through later Sunday. A weaker ridge will temporarily rebuild Monday. Another trough will arrive late Tuesday into Wednesday.

SHORT TERM /TODAY THROUGH SATURDAY/
Satellite imagery continues to show clear skies across Western Washington, with some dissipating low stratus across the coastal waters. Temperatures across the area as of 830 are in the low to mid 50s, up to around 60 along the Strait of Juan de Fuca. Temperatures will continue to warm into the 70s, with a few spots reaching into the lower 80s in the Southwest Interior and through the Cascade valleys. Surface flow will turn east/northeasterly through out the day with northeasterly winds in the the low levels In short, significant warming is expected today across the area with inland temperatures about 10 degrees warmer than Wednesday and temperatures along the coast 15 degrees or so warmer versus yesterday.

Little change in the pattern overnight into Friday. Temperatures aloft continue to warm with 850 mb temperatures in the plus 13 to plus 15C range by late Friday afternoon. Lows tonight in the upper 40s to mid 50s, close to record high minimum temperatures in some locations. Highs Friday a little warmer with 70s to mid 80s.
While not expecting record highs Friday, temperatures this warm are unusual for the first half of May. Seattle has only had 3 days in the 80s on May 10th in 79 years of records.

Even with the surface temperatures warming quickly waters around Western Washington are still very cool. Water temperatures this morning, Lake Washington 54 degrees, Lake Sammamish 56 degrees and Puget Sound in the lower 50s. The rivers are even colder with the Cedar River at 48 degrees, the Skykomish and Tolt 46 degrees and the Skagit checking in with a cold 45 degrees. Cold water shock can be deadly. If you are going to be on the water wear a life jacket.

Upper level ridge weakening Friday night into Saturday. Low level offshore flow turning weak onshore. Winds at 850 and 700 mb turn west northwesterly. With the ridge weakening slightly temperatures aloft cool a touch with model 850 mb temperatures late Saturday afternoon plus 12 or 13C. Another night of mild low temperatures, close to record high minimums in places, in the lower to mid 50s. Highs Saturday much cooler along the coast, in the mid 60s with highs over the interior in the 70s and lower 80s.

LONG TERM /SUNDAY THROUGH WEDNESDAY/
Models in good agreement Sunday with the ridge continuing to weaken and an upper level trough riding over the ridge into British Columbia late in the day. This feature doesn't have much punch with just a chance of showers in the Olympics and Cascades north of about Snoqualmie Pass Sunday night. Ensembles are weaker with the upper level trough versus the operational runs. Operational runs have highs only in the 60s for the interior Sunday. Will lean a little towards the ensembles and go for highs in the 60s and lower 70s.

Upper level ridge tries to rebuild Monday but the ridge axis is well offshore and low level onshore flow continues through the day.
Temperatures aloft continue to cool. This combination will lower high temperatures Monday back into the 60s.

Model solutions become inconsistent Tuesday and Wednesday with the ECMWF building a stronger ridge over the area while the GFS has a front approaching from the northwest Wednesday. High temperature spreads by Wednesday rather large. For Seattle 80 percent of the solutions have the high between 78 and 58 degrees.
With the large amount of uncertainty will split the difference and have highs in the 60s and introduce a slight chance of showers Tuesday night and Wednesday.

AVIATION
Northeasterly winds aloft today with a ridge building off the Pacific coast and moving into the area. Clear skies today into tonight other than a few high clouds at times. Northerly winds will increase midday and remain breezy for some areas, generally 6 to 12 kts with occasional gusts to 20 kts, with winds slowly subsiding this evening.

KSEA...VFR/clear skies expected during the period. North winds 8 to 12 kts with gusts near 20 kts possible through this afternoon, winds transitioning more NE at 5 to 8 kts tonight.

JD

MARINE
High pressure has built up some over the waters, and building will continue over the State of Washington today. With a thermal trough underneath the ridge up the coast, flow is predominately offshore with north/northeast winds. Winds for Thursday may gust up to 20 kt in the coastal waters, as well as Puget Sound and Central Strait of Juan de Fuca (but are expected to remain below hazardous levels for small craft). This pattern will continue into the weekend, until a trough moves through the region Saturday/Sunday. Gusty winds above 20 kt are possible in the Strait of Juan de Fuca and the outer coastal waters - will continue to monitor for possible headlines.

Seas of 5 to 8 feet through late week into next week.
