Area Forecast Discussion

National Weather Service Seattle WA

910 PM PDT Sat Aug 19 2017



.SYNOPSIS...Light onshore flow will give some areas of low clouds in 

the late night and morning hours through Monday. The areas of night 

and morning low clouds and fog should mainly on the coast and near 

the water. High pressure will shift over the region Monday and 

Tuesday for warmer temperatures. A trough will bring cooler weather 

and a chance of showers late Wednesday and Thursday. High pressure 

will build over the area again toward the end of the week.



&&



.SHORT TERM...A few areas of low clouds should form along the 

coast late tonight and there might be a few patches inland. Light 

northwesterly onshore flow will give another nice day on Sunday 

with highs into the 70s across much of the interior. Upper ridging 

amplifies just offshore Sunday night then progresses eastward across

the region Monday and into Western Montana Tuesday afternoon. This

ridge will give sunny weather except for shallow morning low clouds

and fog--but mainly for the coast and over the waters. Around Puget

Sound and up through the inland waters fog or low clouds should burn

off over land pretty quickly but could linger through mid morning

over the water.



.LONG TERM...Onshore flow later Tuesday will usher in a marine

push Tuesday afternoon and evening that will result in increased

clouds. The push will be followed by a frontal system that will 

move across the area Wednesday night and a rather deep upper level

trough Thursday through Thursday night. Long term models appear to

be converging on a solution (between the GFS and ECMWF) where 

there will be a threat of showers Wednesday afternoon through 

Thursday evening. Thursday high temperatures will likely not reach

the 70 degree mark across most of the area with the clouds, some 

showers, and the cooler air mass. Snow levels are expected to fall

to 6000 to 7000 feet in the North Cascades Thursday or Thursday 

night, and may impact campers and backpackers at higher 

elevations.



As high pressure builds into southeastern British Columbia Friday

through the weekend, offshore flow will give a good warming and

drying trend. Albrecht



&&



.AVIATION...Northwest flow aloft over Western Washington tonight 

and Sunday as an upper ridge remains over the offshore waters. At

the surface, onshore flow will continue with high pressure 

offshore and lower pressure east of the Cascades. 



Just some high clouds over most of the area through Sunday.

Shallow marine layer along the coast with mvfr ceilings 

developing for a few hours Sunday morning. 



KSEA...Just some high clouds at times through Sunday. North

northeast wind 5 to 10 kt backing to northwest again midday Sunday.

Felton



&&



.MARINE...A typical August pattern will prevail through the

middle of next week. Expect onshore flow of varying strength to 

persist due to high pressure offshore and lower pressure east of 

the Cascades. A weak system will approach the coastal waters on 

Wednesday and move inland Thursday. Small craft advisory west

winds are likely in the central and eastern Strait of Juan de 

Fuca in the evening and early morning hours each night. Felton



&&



.SEW WATCHES/WARNINGS/ADVISORIES...

WA...None.

PZ...Small Craft Advisory until 5 AM PDT Sunday for Central U.S. 

     Waters Strait Of Juan De Fuca-East Entrance U.S. Waters 

     Strait Of Juan De Fuca.
