Area Forecast Discussion National Weather Service Seattle WA 902 AM PDT Thu Sep 16 2021

UPDATE /0900/. No major changes to the forecast this morning. Clouds from the approaching weather system will begin to move into the Western Washington area later today. Southerly winds ahead of the cold front will begin to pick up after midnight tonight. Wind advisories remain out for where wind is expected to be the highest (the coast, San Juans, Island County, Western Whatcom and Skagit Counties). Winds should peak later Friday afternoon, but are expected to remain breezy through the weekend. Widespread rainfall will begin after the winds pick up. One to two inches are expected for most locations in the region, but the coast and the mountains will likely see closer to 2-4 inches for Friday and Saturday. Rain will be heavy at times and will cause decreases in visibility. With the rain and dry soils we anticipate there could be some areas with some ponding and urban flooding. As for area rivers we expect rapid rises due to a delay in water being absorbed into the soil. At this time we are not anticipating any rivers to reach flood stage but they will need to be watched closely. There remains the chance of thunderstorms throughout the area for both Saturday and Sunday.

The previous forecast with updated marine and aviation sections are below.

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. An upper ridge will move through the area today with westerly flow aloft. A strong frontal system will approach the coast tonight. The air mass will be stable. Clear skies this morning after some patchy valley low clouds and fog burns off. High clouds will increase from the west this afternoon. Ceilings will gradually lower tonight as the frontal system reaches the area. Low clouds should develop at the coast, Strait of Juan de Fuca, and north interior Friday morning with occasional reduced visibilities in rain.

KSEA . Clear this morning. Increasing high clouds this afternoon and evening. Mid clouds developing after midnight. Light wind will become northwest 4-8 knots this afternoon then light southeast tonight the south 8-12 knots Friday morning.

Schneider

MARINE. Weak northwesterly onshore flow will prevail today with high pressure off the coast. Southerly winds will develop tonight ahead of an approaching frontal system. The aforementioned vigorous frontal system will bring southerly gales to most waters on Friday. Small craft advisory strength southerly winds will continue most waters on Saturday. Winds will ease below small craft advisory strength on Sunday. High pressure just off the coast will bring weak onshore flow for Monday.

HYDROLOGY. A vigorous frontal system will bring heavy rains to the area Friday and Friday night. River flooding is not expected at this time sharp rises on areas rivers are likely. Due to the dry soils there is some uncertainty as to how long it will take for the water to absorb into the banks, so river conditions will be monitored carefully, particularly for the flood prone Skokomish river in Mason county. Localized minor urban flooding is also possible on Friday in areas of heavier rains.
