Area Forecast Discussion National Weather Service Seattle WA 259 AM PDT Thu Jul 16 2020

SYNOPSIS. Marine layer clouds will spread across the lowlands of Western Washington today ahead of an approaching trough. Friday will be cool and cloudy with some areas of showers or drizzle as the trough moves eastward. An upper ridge will build over the weekend and into early next week for a period of sunny warm weather before another marine push by the middle of next week.

SHORT TERM /TODAY THROUGH SATURDAY/. Shallow marine moisture continues to make steady progress inland this morning through the Strait of Juan de Fuca and Chehalis Gap as low level onshore flow increases ahead of an approaching trough. Low clouds should spread to most of the interior lowlands by around sunrise. They may scatter out by afternoon, but higher level cloudiness will be increasing through the afternoon. Afternoon high temperatures will run 6 to 10 degrees cooler than Wednesday across much of the region. The marine layer will deepen tonight as onshore flow increases with some areas of drizzle or light showers developing overnight into Friday morning. Friday will be the coolest day of the next several, but clouds should break up by late afternoon as upper ridging begins to build back into the area. Heights continue to rise on Saturday as upper ridging gains amplitude offshore. After some brief areas of morning clouds, sunshine returns for Saturday with temperatures bouncing back to near or a little above normal with upper 60s coast and 75 to 80 for much of the interior lowlands.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The offshore ridge continues to strengthen to round out the weekend. Low level flow will only be weakly onshore on Sunday and this will keep morning clouds limited to the coast. High temperatures will continue their climb with 70s coastal areas and mid 70s to mid 80s interior. By Monday, strong ridging remains in place aloft and thermally induced low pressure at the surface will extend northward from Oregon's Willamette Valley into the Western Washington interior lowlands. Areas from Seattle southward should reach the mid to upper 80s. Tuesday could be much the same as Monday, but low level onshore will be increasing by late in the day. That'll cool the coastal areas, but it's likely to remain quite warm inland. A system passing well to our north will induce a marine push around the middle of next week. Temperatures will cool somewhat with more prevalent morning clouds. But unlike the recent past, we'll see temperatures merely return to seasonal levels with dry conditions continuing. 27

AVIATION. Westerly flow aloft with strengthening low level onshore flow will result in widespread marine stratus with MVFR ceilings through much of the interior. Lower, IFR ceilings possible particularly along the coast. Ceilings will lift through the day with VFR conditions expected over much of the interior. Ceilings along the coast will likely remain at or near MVFR levels through the afternoon and evening. Ceiling will lower again Thurs day evening into Friday morning to MVFR levels with pockets of IFR, particularly along the coast. In addition to ceilings expect gusty winds this afternoon and evening.

KSEA . Marine stratus is expected to develop around 12Z with MVFR conditions through 16Z. Ceilings will lift to VFR levels through late morning. Light N winds will become SW 6-8 kts through mid morning then strengthen through the afternoon to 8-10 kts gusting to 15 kts. Winds will ease to 6-8 kts during the late evening and remain SW.

MARINE. Persistent offshore high pressure will remain in place for the next couple of days, with a thermally induced surface trough along the south Oregon coast. This will support persistent north to northwest flow over the coastal waters with the strongest winds during the evening hours as well as through Juan de Fuca. Onshore pressure gradients again support gale conditions developing through the central and eastern strait late this afternoon and evening. Seas over the coastal waters will remain 3 to 6 ft, building in conjunction with the stronger winds and will remain rather steep through much of the week.

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

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.
