Area Forecast Discussion National Weather Service Seattle WA 851 AM PDT Tue Aug 11 2020

UPDATE. Clouds have made it into much of the Puget Sound this morning with stratus more widespread along the coast and Southwest Interior. Clouds will clear for mostly sunny skies this afternoon. Clouds around into this evening as a weak wave moves through. Some hi-res guidance suggests possibly a weak convergence zone developing near the central Puget Sound for some light precipitation, will monitor into this afternoon. Temperatures today will be cooler in the low to mid 70s across the area.

SYNOPSIS. A weak system will bring increased cloud cover and cooler temperatures today and Wednesday. A ridge of high pressure will begin to build into the region late this week, yielding rising temperatures through the weekend.

SHORT TERM /TODAY THROUGH THURSDAY/. A return to below average temperatures is on tap today as onshore flow has returned to Western Washington. Gradients are somewhat on the weak side at this hour (a little above +1 OTH-SEA), so this will generally keep most of the low marine Stratus west of Puget Sound this morning. Low status will lift and mix out late this morning with mid to high clouds increasing through the afternoon ahead of a weak upper level disturbance. Temperatures this afternoon will run several degrees below normal, with highs in the 60s and low 70s. Wednesday will be several degrees cooler than this afternoon, as mid- level temperatures will generally cool around 5 degrees C on average with the passage of the next upper level shortwave trough. Temperatures around 0 degrees C at 700mb coupled with drier mid- level air will allow for cooler air to mix down to the surface on Wednesday afternoon, with most locations in the upper 60s to around 70 degrees for highs. A warming trend will commence on Thursday as the upper level ridge over the northeast Pacific amplifies, yielding rising midlevel heights over the Pacific Northwest.

Pullin

LONG TERM /FRIDAY THROUGH MONDAY/. Expect a warming trend Friday into the weekend as an upper level ridge builds over the Pac NW. Temperatures will peak on Sunday as the low level flow turns offshore. Highs on Sunday will reach the mid 80s (inland from the water) with a few low 90s possible (especially over the SW Interior). By Monday the ridge axis will shift east into eastern WA while a trough digs offshore. This approaching trough may trigger showers across western WA although exact timing is still unclear in the models. A flip to onshore flow will bring cooler conditions to the coast with temperatures back in the 60s. The interior will remain warm with temps in the low to mid 80s. The trough will bring cooler conditions (closer to average) and additional showers as we move into Monday night and Tuesday.

33

AVIATION. MVFR CIGs expected at TAF sites along the southern sound and in the Chehalis River valley through the rest of this morning. Onshore flow is expected to persist throughout today and tomorrow. MVFR and VFR CIGs for all other TAF locations. KHQM currently has IFR CIGs, with this expected to continue into the morning hours. Increasing mid to upper level clouds later this evening. Prevailing winds out of the south/southwest today at speeds generally AOB 10kts.

KSEA . Current MVFR conditions are expected to improve to VFR conditions expected to improve as clouds begin to thin out. Southwesterly prevailing wind AOB 10 kts. Low stratus in the vicinity of the terminal later this morning expected to lift and scatter out this afternoon. Increasing mid to high clouds late in the period. Butwin

MARINE. Onshore flow will persist through Thursday before a ridge of high pressure builds over the area. Strong pushes are likely through the Strait each afternoon and evening through at least Thursday. Brief period of gale force winds are expected for the central and eastern Strait later this afternoon and evening so have upgraded the small craft advisory to a gale warning with morning update. Strong winds may bleed over into Admiralty Inlet and northern Inland waters so have also issued a small craft advisory for those areas. Winds and swell across the coastal waters will gradually diminish below criteria by Wednesday morning.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
