Area Forecast Discussion National Weather Service Seattle WA 830 PM PDT Thu May 2 2024

SYNOPSIS
Dry and mostly clear conditions through tonight. A wetter storm system will move into western Washington on Friday, and cool and unsettled conditions will prevail through the weekend and early next week.

SHORT TERM /TONIGHT THROUGH SUNDAY/
Clouds and showers over the higher terrain have quickly dissipated with the sun setting this evening. We've got a mostly clear and cool night ahead then clouds increase through the day on Friday ahead of the next frontal system. Rain reaches coastal areas and the Olympic Peninsula by late Friday afternoon, but interior areas east of Puget Sound look to remain mainly dry until perhaps midnight or so. Forecast trends look on track with no anticipated evening updates. Previous discussion follows with updates to marine/aviation portions. 27

Weak high pressure is bringing sunny and dry conditions to much of western WA today with temps in the 50s and 60s. There are a few pop- up showers over the Cascades and cells may drift into the foothills this afternoon with easterly steering flow aloft. Shower activity will fade away this evening as the ridge axis shifts inland.

The ridge exits east on Friday while a deep upper low develops offshore. A frontal system will spread rain to the coast mid to late morning with rain spreading inland during the afternoon and evening. The air mass will remain mild, though, under deep southerly flow. Temperatures in the interior will reach the mid to upper 60s ahead of the rainfall.

The weekend is looking cool and showery as the deep upper low slowly tracks inland. There's plenty of wrap-around moisture clipping western WA on Saturday with little break in the action.
Highs on Saturday are only in the low to mid 50s. Onshore flow will increase on Sunday keeping western WA cool, cloudy and showery. It'll be windy too with gust around 20-30 mph (especially around the south sound and Strait of Juan de Fuca). 33

LONG TERM /MONDAY THROUGH THURSDAY/
Western WA remains under solid onshore flow through early next week, keeping us cool and wet through the period. The air mass is slightly unstable on Monday and added lift from a trough axis may trigger a few thunderstorms too. Onshore flow eases by midweek and drier N/NW flow may give us a little break. Warmer and drier weather is favored for the latter half of the week with high pressure. 33

AVIATION
Winds aloft northwesterly becoming southwesterly tomorrow afternoon as a small upper-level ridge moves over the area tonight followed closely behind a larger trough. Mostly clear skies across western Washington this afternoon as high pressure moves into the NE Pacific. Northerly to onshore flow will continue to weaken this evening. The wind will shift back to light offshore/southeasterly late tonight as the next frontal system approaches the region. Winds may be gusty along the coast tomorrow afternoon. Cigs expected to remain VFR through most of the TAF period. Mid to high level clouds will filter in early tomorrow morning ahead of an incoming frontal system, with lower ceilings (but remaining VFR) tomorrow evening. Some MVFR may be possible along the coast and towards OLM at the end of the period. Showers will reach the Pacific coast late tomorrow morning into tomorrow afternoon, nor moving into the interior until late tomorrow afternoon and evening. Areas north of the Seattle area may not see any significant rain in this TAF period.

KSEA...VFR conditions through the TAF period. High clouds move in this evening, with lower ceilings developing into the end of the TAF period. Light northwest winds veering to light southeasterly early this evening as the next frontal system approaches. Winds will pick up to southwesterly 8-10 kt by tomorrow afternoon. Rain is not expected until tomorrow afternoon into tomorrow evening, and will only be showery in nature.

MARINE
Weak high pressure over the area waters continue into tonight for overall calm conditions. The next frontal system will move into the area waters Friday into Saturday, where southerly winds will increase across the outer coastal waters through Friday evening. As such, a Small Craft Advisory remains in effect for the coastal waters farther than 10 NM. Several westerly pushes down the Strait of Juan de Fuca look likely this weekend into early next week with a significant onshore push following the frontal system.
Another system looks to arrive in the region late Sunday into Monday.

Combined seas across the coastal waters will generally hover between 3-5 ft through Friday, before increasing towards 6-7 ft over the weekend. Confidence is still high regarding seas approaching 9-11 ft Monday night into Tuesday.

Kristell/LH

HYDROLOGY
No river flooding is expected over the next 7 days.
