Area Forecast Discussion National Weather Service Seattle WA 355 AM PDT Thu Sep 16 2021

SYNOPSIS. An upper ridge will bring dry weather today. A vigorous frontal system will bring rain and windy conditions on Friday. An upper trough will bring cool and showery weather over the weekend with isolated thunderstorms possible. Drier and more tranquil weather is expected the first half of of next week.

SHORT TERM /TODAY THROUGH SATURDAY/. Pretty quiet this early morning as upper level ridging exerts its influence over W WA. Current satellite imagery shows that while some low clouds are present, the seem to be moving southward and thinning out a bit. Current radar is clear. This upper level ridge will remain the main weather factor for the rest of today allowing dry conditions to continue and generally sunny skies over much of the area. High temps will run a little bit below normal with mid to upper 60s for most lowland locations, lower 60s along the coast.

A vigorous frontal system will move through the area Friday and Friday night, bringing rain, heavy at times, and windy conditions to some locations, particularly the North Interior /including western portions of Skagit and Whatcom counties/ as well as the Admiralty Inlet area and the San Juans. A wind advisory is up for this area as well as for along the coast for much of the day Friday. Models remain consistent with fairly impressive rain totals for the area as the front moves through slowly throughout the day. The mountains look to pick up 2-4" of rain with locally higher totals possible while lowland locations should get 1-2" of rain. Highs Friday expected to be in the lower to mid 60s.

The front pushes further inland Saturday, moving east of the Cascades by mid-morning. In its place, the parent upper level trough will take up residence over W WA allowing for showers to continue for much of the day. The trough itself looks to have enough dynamics with it to bring some instability and thus looking at a slight chance for some thunderstorms, mainly during the afternoon and evening hours. Snow levels will fall to 6500-7000 feet on Saturday and the higher terrain should get the first accumulating snows of the season. 18

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The trough axis finally starts making its way east of the Cascades Sunday, however the back end of the trough still has plenty of moisture for shower chances to continue. Lingering instability will once again give rise for a limited thunderstorm threat over portions of W WA. The aforementioned snow levels will remain fairly static, so once again additional snowfall on the highest terrain remains a possibility. High temps Sunday expected to be impressively below normal /10 or more degrees below in some spots/ with highs only in the lower 60s areawide.

Deterministic models are quick to dry things up as an upper level ridge sets up for the start of next week, however enough uncertainty remains in ensemble members that PoPs cannot be entirely ruled out for the remainder of the forecast period. These PoPs remain low /generally slight chance to low-end chance/ . so the overall thought across the board, deterministic and ensemble, is a relative dry period. High temps each day should be mostly in the 60s. 18

AVIATION. Mostly clear skies except a few patches of mainly valley fog around daybreak. The air is dry and stable. High clouds will arrive late today ahead of a cold front that will reach the area on Friday. 19

KSEA . Mostly clear skies, some high clouds later today.

MARINE. Not much in the way of wind today, but southerlies will increase overnight tonight and a vigorous cold front will arrive on Friday with gale warnings for the coastal waters and north, with small craft advisory winds elsewhere. 19

HYDROLOGY. A vigorous frontal system will bring heavy rains to the area Friday and Friday night. River flooding is not expected at this time with dry antecedent conditions and low river flows but sharp rises on areas rivers are likely. There is an outside chance the exceptionally flood-prone Skokomish river in Mason county could reach flood stage Saturday morning. Localized minor urban flooding is also possible on Friday in areas of heavier rains. Schneider
