Area Forecast Discussion National Weather Service Seattle WA 847 AM PDT Mon Oct 18 2021

UPDATE. No changes to the overall forecast. See marine and aviation section for updates.

SYNOPSIS. Western Washington will see a break in the weather through Tuesday. We'll then see more rain and breezy winds with the next system on Wednesday. Additional fronts will arrive later in the week, keeping the weather pattern active.

SHORT TERM /TODAY THROUGH WEDNESDAY/. Onshore flow continues this morning and western WA is seeing lingering low level moisture and patchy fog (and possible drizzle), especially in the interior. Clouds will slowly scatter this afternoon for a few sunbreaks and highs in the mid 50s. Lows will be chilly tonight under partly cloudy skies - temperatures around the sound sound will dip into the 30s. Tuesday will be sunnier and warmer under deep southerly flow - expect highs in the 60s.

The next Pacific frontal system will reach the area on Wednesday bringing more rain to the region. The air mass will remain cool and unstable for a slight chance of thunderstorms along the coast. Winds along the coast will be breezy/gusty as well. The upper trough axis will exit the region Wednesday night with showers tapering down. 33

LONG TERM /THURSDAY THROUGH SUNDAY/. The pattern remains active as we move into Thursday while a deep low (960 mb) spins over the offshore waters then tracks north toward Haida Gwaii. This system brings an additional round of rain and breezy winds (coast again) through Friday. More active weather is anticipated over the weekend with a longwave trough over the West. Ensemble guidance agrees that we're in for a wet period of weather although there remains some uncertainty on exact timing and total precipitation amounts. One additional note, snow levels drop to around 4500-5000 feet Saturday and Sunday with a few inches of snow possible on the higher mountain peaks. 33

AVIATION. The flow aloft will be southerly as high pressure builds into the area. MVFR and VFR cigs for most this morning with areas of LIFR along the southern Puget Sound, mainly near KOLM. VFR cigs later this afternoon into tonight as clouds scatter. LIFR cigs will be possible late tonight into Tuesday morning with lower clouds. Winds will mainly be light today for the area.

KSEA . MVFR cigs through this morning, with VFR at times. VFR this afternoon into early tonight. Low clouds may develop late tonight into Tuesday morning for LIFR cigs. Mainly light Northwesterly winds through today with more NoRtheasterly winds tonight. JD

MARINE. Light winds today for the waters. A storm system will near the area later tonight,increasing southerly winds over the Coastal waters. Small Craft Advisory winds tonight into Tuesday for the Coastal Waters with the south winds. Gales will be possible Tuesday night into Wednesday morning, especially for the outer coastal waters. SCA winds for the interior waters Tuesday night into Wednesday.

The active pattern will continue through the weekend with troughing over the Pacific. Breezy will be breezy Wednesday evening with a stronger system moving toward the area Wednesday night into Thursday. Gales are possible with this system for the offshore waters with a strong easterly gradient through the Strait of Juan de Fuca. Additional headlines Thursday for other interior waters.
