Area Forecast Discussion National Weather Service Seattle WA 219 PM PDT Tue Oct 3 2023

SYNOPSIS
An upper ridge located offshore will build over Western Washington into Wednesday. Light low level flow will keep moisture near the surface through Wednesday, however, resulting in times of drizzle or light showers. Increasing northerly and offshore flow into Thursday. A warmer, drier pattern Thursday into the weekend. A more active pattern early next week.

SHORT TERM /TONIGHT THROUGH FRIDAY/
Mostly cloudy conditions this afternoon for most of Western Washington with generally clear skies across the northern Olympic Peninsula and towards the San Juan Islands. Some clearing into this evening with increasing clouds tonight into Wednesday morning as a trough moves across southern Canada, bringing some slight enhancement to precipitation potential Wednesday morning. Generally light rain and drizzle will exist during this period. Conditions will become drier later Wednesday into Wednesday night as upper ridging builds more into the Pacific Northwest.

The upper ridge will bring more northerly flow on Thursday with low level offshore flow developing on Friday. Given the abundant moisture at the surface and clear skies, fog development will be likely Thursday morning, as well as Friday morning. However, clearing is expected each afternoon with increasing winds.
Temperatures will also warm Thursday into the mid 60s to low 70s, and further Friday into the 70s for most areas, and even a few 80s are possible in the Cascade valleys.

LONG TERM /SATURDAY THROUGH TUESDAY/
The upper ridge situated across the Pacific Northwest late week will slowly progress eastward over the weekend. Saturday will likely be the warmest day for the interior, with widespread 70s. There is some spread in guidance, however, with NBM suggesting a 20% chance of KSEA reaching 80 degrees Saturday afternoon. Onshore flow will then begin to increase on Sunday as the ridge shifts east, and troughing developing across the NE Pacific. This will allow for increasing clouds, as well as some cooling. In addition, ensemble guidance suggests the potential for increasing precipitation beginning Sunday afternoon for the Olympic Peninsula. A more active period of weather is likely beginning late Sunday into Monday with a frontal system tapping into sub-tropical moisture for increasing rain and perhaps breezy winds. Troughing will likely dominate the pattern into Tuesday for cooler weather and potential showers. JD

AVIATION
Northwest flow aloft will continue as broad ridging offshore starts to nudge closer to W WA. Low clouds have gradually broken apart and lifted this afternoon around with a mix of VFR/MVFR conditions scattered through area terminals. This trend likely will continue into early this evening, before low MVFR ceilings return around 06z-09z and continue into Wednesday morning. Conditions will likely deteriorate to IFR as we head into the morning, with a 40% chance of IFR ceilings through the interior heading into 15z. With light low level flow, and a more stable airmass filtering into the region, patchy fog will be possible tomorrow morning through interior terminals, and can locally deteriorate conditions to even LIFR, especially around 12z-16z.

KSEA...Conditions have recovered to VFR this afternoon, with some mid level scattered clouds around. West/south-west winds this afternoon have been rather light, and will continue through the overnight period, possibly taking a more southerly component at times. Low MVFR clouds return tonight around 10z-12z, with at least a 25 to 35 percent chance of LIFR ceilings heading into 13z-16z.

MARINE
Surface ridging will continue to amplify offshore, with northwesterlies over the coastal waters. A thermally induced trough will start to develop near the coastline on Thursday, shifting inland on Friday, with offshore flow through the interior waters. Small craft advisory easterlies look to be possible Thursday night into Friday for the Central and Eastern Strait of Juan De Fuca.

Coastal seas around 6 to 8 feet this afternoon will gradually subside to around 4 to 6 feet through midweek.
