Area Forecast Discussion National Weather Service Seattle WA 809 PM PDT Fri May 3 2024

SYNOPSIS
A shift back to cool, wet unsettled conditions will prevail across Western Washington through early next week. A significant change in the weather pattern is expected for the second half of next week as high pressure aloft leads to warmer and drier conditions.

SHORT TERM /TONIGHT THROUGH MONDAY/
Light rain ahead of incoming front is making slow progress into the interior as expected. Rain chances around much of Puget Sound will increase on Saturday as weakening front pushes across the region, but the bulk of the precip with this initial system looks to fall south and west of Seattle. No changes anticipated this evening to existing forecast. Previous discussion follows with updates to marine and aviation portions. 27

Rain had yet to reach coastal areas as of 130 PDT (2030Z) as an occluded front ahead of a broad upper trough offshore gradually advances toward the region. Rain will spread across the Olympic Peninsula by early evening, but will be slow to get into Puget Sound eastward initially. As the upper trough axis shifts into the Oregon coastal waters early Saturday, a weakening frontal boundary will slowly lift northeastward across Western Washington. Low level easterly flow will shift onshore and increase behind it. This will allow the air mass to moisten up for increasing precip coverage by Saturday afternoon. Overall QPF will be heavily focused on the southwest half of the CWA

The upper trough is expected to shift into the Great Basin by early Sunday with wrap-around precip continuing to fall across parts of Western Washington. Onshore flow will ramp up through the day on Sunday as another upper trough moves toward the area.
Increasing orographic lift will lead to a fairly wet Sunday afternoon and evening in the mountains, but much of the Puget Sound area looks to be rain shadowed.

An upper trough axis will swing onshore on Monday. With colder air aloft, this will destabilize things enough to warrant the mention of a slight chance of thunderstorms. Snow levels will dip to some of the higher passes, but amounts look to be light. A convergence zone looks likely to form on Monday as well.
Temperatures throughout the short term forecast period will be several degrees below normal, but changes are afoot.


LONG TERM /TUESDAY THROUGH FRIDAY/
Cool, showery conditions will persist into Tuesday as the upper trough axis slowly shifts east of the Cascades. For Wednesday and beyond, ensembles are nearly unanimous that upper ridging will build over the northeast Pacific as downstream a broad upper trough takes up residence over the eastern two thirds of the lower 48. There is still considerable uncertainty with regards to how warm it will get.
Current forecasts reflect the NBM 50th percentile forecast...which brings mid 70s to Seattle by next Friday. A noteworthy number of ensemble members (particularly the GFS) have temperatures teasing 80 degrees by late next week for some areas. Rough winds do shake the darling buds of May, but we might compare thee to a summers day by next weekend. 27

AVIATION
An upper level trough will move through western Washington this evening with south to southwesterly flow aloft. A frontal system is beginning to approach the area, with light rain falling throughout the Pacific Coast and the Southwest Interior.
Conditions remain VFR this evening with MVFR ceilings moving onshore as the front approaches. Rain will struggle to become widespread in the interior north of Seattle tomorrow. Scattered showers move in overnight becoming more widespread later tomorrow morning.
VFR ceilings continue through tomorrow morning through the interior, falling to MVFR tomorrow afternoon. MVFR along the coast tonight and tomorrow and around OLM, with isolated IFR conditions possible.

Winds at the surface will remain west to southwesterly through most of the TAF period. Winds may briefly turn light northerly overnight, but will turn back to southwesterly tomorrow. Winds may be gusty tomorrow with the frontal passage.

KSEA...VFR this evening with ceilings gently lowering as a front moving onshore. Rain to the south and west of the terminal, likely not fully reaching the terminal until tomorrow. Ceilings lowering to low end VFR, with MVFR conditions possible as early as 15Z Saturday but not expected to be longer lasting until tomorrow evening. Winds WSW and decreasing overnight. Winds will likely turn northerly overnight before spinning back around to southwesterly tomorrow morning.

MARINE
A frontal system is currently traversing the coastal waters and will continue to work its way onshore tonight into tomorrow. Winds will decrease tonight as the front moves through the area. As such, the Small Craft Advisory has been allowed to expire.
Heading into the weekend, guidance suggests several westerly pushes through the Strait of Juan De Fuca, likely yielding additional headlines. Another system looks to track into the area waters through the first half of next week.

Combined seas this afternoon around 3 to 5 feet will gradually increase to around 6 to 8 feet by Sunday. Confidence is increasing that seas look to hover around 9 to 11 feet Monday night into tuesday, with the higher heights mostly in the outer water zones.
