Area Forecast Discussion National Weather Service Seattle WA 235 PM PDT Thu Aug 6 2020

SYNOPSIS. Weak high pressure will rebuild into the region tonight and early Friday for drier conditions. A weak system will brush the region Friday night and early Saturday for a chance of showers before high pressure returns for warmer and drier conditions Sunday and Monday. An upper trough will return in the middle of next week for cooler temperatures and additional cloud cover.

SHORT TERM /TONIGHT THROUGH SUNDAY/. Convergence zone activity continues this afternoon in wake of the frontal system that passed across the area this morning. Onshore flow will relax this evening with most shower activity coming to an end. Weak high pressure aloft will build into the region tonight and early Friday, but onshore flow will keep a fair amount of clouds across Western Washington with temperatures remaining below normal. A weak system brushes the area Friday night and early Saturday for additional cloud cover and some light precipitation for the coast and perhaps North Interior. Heights begin rising later Saturday as upper ridging begins building back into the area for a return to warmer and sunnier conditions across Western Washington on Sunday with temperatures bouncing back to around seasonal normals for early August.

LONG TERM /MONDAY THROUGH THURSDAY/. Upper level ridging reaches its maximum amplitude early Monday with 500 millibar heights in the mid 580s dam and low level flow northerly. Upper ridging quickly flattens by later Monday and low level onshore flow increases with the high temperature forecast potentially a little tricky. Upper level troughing takes up residence to our north Tuesday through Thursday for persistent onshore flow leading to cooler temperatures and more widespread night and morning clouds. At this time, it appears that it will remain generally dry through the extended forecast period. 27

AVIATION. Westerly flow aloft will transition northwesterly as an upper trough moves east of the area. VFR cigs across the area this afternoon with some convergence activity across King/Snohomish County. Mostly dry conditions into tonight with a few showers around the convergence zone. VFR into this evening with MVFR Friday morning with stratus, IFR possible in spots. Southwest winds across the southern Puget Sound with N winds across spots in the central Puget Sound, mainly KPAE and KBFI. A few gusts to 20 knots possible into this evening. JD

KSEA . VFR cigs. Clouds around into tonight. MVFR Friday morning with stratus. South winds should be main direction, however, N winds possible this afternoon into this evening (22z-04z). Gusts to 20 knots possible today. JD

MARINE. Onshore flow through the weekend. Gales possible for the Strait of Juan de Fuca into tonight with SCA winds for the northern inland waters and admiralty inlet area. Flow will be lighter late tonight into Friday. A second, weaker, front will diminish over the Coastal Waters Friday night. NW flow for the coastal waters with increasing onshore flow Saturday afternoon for SCA winds possible over the coast and Strait of Juan de Fuca. Onshore flow into next week. JD

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

SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ . Small Craft Advisory from 11 PM this evening to 5 AM PDT Friday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
