Area Forecast Discussion National Weather Service Seattle WA 843 PM PDT Fri Aug 7 2020

SYNOPSIS. A weak front is breaking up over Western Washington this evening. Areas of light rain will turn to a few showers that will taper off into Saturday. High pressure will return for warmer and drier conditions Sunday and Monday. An upper trough will return around the middle of next week for cooler temperatures and additional cloud cover.

SHORT TERM /TONIGHT THROUGH MONDAY/. A weak front is over Western Washington this evening with a few areas of light rain. A few showers will taper off on Saturday with some clearing developing in the afternoon. Temperatures Saturday will remain a few degrees below normal in stronger onshore flow. A weak ridge of high pressure will begin to build over the region on Sunday and temps will warm. With weakening onshore flow late Sunday and into Monday, expect to see high temps return to the 80s Monday afternoon. Clouds begin to return late Monday ahead of the next weak disturbance approaching the region.

LONG TERM /TUESDAY THROUGH FRIDAY/. The flow aloft turns zonal on Tuesday as a trough passes by well to our north. This will increase the onshore flow and cool temperatures a few notches before a secondary and potentially deeper trough swings across the region late Wednesday and Thursday. There's a fair amount of uncertainty with respect to precipitation chances toward midweek. At this time, cooler than normal temperatures along with extensive night and morning clouds are a good bet and perhaps some shower activity across the north half of the area and in the Cascades. 27

AVIATION. A weak front will continue to brush past the region this evening, with radar currently showing areas of light rain across much of Western Washington. Light rain will taper to showers overnight. Ceilings remain VFR this evening, however expect widespread low VFR to MVFR ceilings to develop from west to east overnight, with local IFR ceilings possible along the coast.

KSEA . Terminal will likely see a few light showers this evening. Current conditions remain VFR and expect predominant lower VFR conditions to continue overnight with a few hours of MVFR 12z- 16z. Expect a return to VFR conditions between 19z-22Z. Surface winds will be light northerly through much of the night, before returning to south/southwest by early Saturday. Cullen/Borth

MARINE. A weak front will continue to make its way across the waters this evening. Northerly to northwesterly winds return over the coastal waters Saturday with a stronger onshore push through the Strait of Juan de Fuca likely bringing advisory strength winds. Meanwhile, strengthening surface gradient will likely lead to advisory strength winds over portions of the coastal waters Saturday afternoon and evening. Northwesterly winds persist over the coastal waters through early next week. Seas over the coastal waters generally 5-7 ft through early next week, largest over the outer waters, and dominated by a northwest swell. Cullen/Borth

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.
