Area Forecast Discussion National Weather Service Seattle WA 907 PM PDT Tue May 26 2020

SYNOPSIS. Upper level high pressure offshore will shift inland Wednesday and remain through Friday. This will lead to sunny and warmer conditions across Western Washington for the next few days. An upper level low will lift northeast into the Pacific Northwest Saturday and Sunday, bringing a return of cooler and wet weather with the potential for isolated thunderstorms, especially near the Cascades.

SHORT TERM /TONIGHT THROUGH FRIDAY/. Satellite imagery showing just some high clouds over western Washington this evening ( colorful sunset in progress ). Temperatures at 9 pm/04z are in the mid 50s to mid 60s.

Forecast on track this evening with upper level ridge offshore shifting inland Wednesday and remaining over the area into Friday. Surface gradients try to turn offshore but don't quite make it with the cross Cascade gradient going flat Thursday and Friday afternoon but not turning negative. Temperatures aloft warming but readings are not that impressive with model 850 mb temps peaking in the plus 14 to 16C range Thursday afternoon. With the lack offshore flow and very warm temperatures aloft current forecast of highs peaking in the 70s to lower 80s Thursday and Friday looks good. Could see the warmest locations creep into the mid 80s both days. For Wednesday warming trend begins with only a few high clouds over the area. Dew points are in the upper 40s and lower 50s so there could be some patchy valley fog in the morning but even if it does form it will not last long. Highs Wednesday mostly in the 70s with a few lower 80s over the Southwest Interior. Forecast on track tonight. Felton

LONG TERM /SATURDAY THROUGH TUESDAY/. Previous discussion follows. By early Saturday, a deep upper low that will begin offshore of the California coast will move northeast toward the region. This will bring the return of showers to portions of the area for the weekend, along with some potential for thunderstorms. At this point, it appears the best forcing will be east of the Cascades, but there will be a window of time where some stronger showers could develop on the west side of the crest. As a result, have included a slight chance mention of thunderstorms for now. Nonetheless, temperatures will be considerably cooler this weekend - especially Sunday, where highs in the mid 60s may be common. Another area of weak high pressure may arrive Monday for another generally dry and slightly warmer (albeit, partly cloudy) day before the next disturbance approaches Tuesday.

AVIATION. Northwesterly flow aloft becoming southwesterly Wednesday as upper level ridge moves over the area. Surface gradients becoming northerly. Just some high clouds over the area through Wednesday. Some patchy fog possible in the valleys early Wednesday morning.

KSEA . Just some high clouds through Wednesday. Light northwesterly winds becoming north northeast 4 to 8 knots Wednesday morning. Felton

MARINE. Weak high pressure just offshore with thermal low pressure along the northern California coast will continue into Friday. A weather system will move into the area from the south over the weekend. Small craft advisory winds are expected over the coastal waters Thursday through Friday with diurnally driven small craft advisory winds in the central and east entrance of the Strait of Juan de Fuca late in the day Thursday and Friday. Felton

HYDROLOGY. The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
