Area Forecast Discussion National Weather Service Seattle WA 341 PM PDT Tue Apr 23 2024

SYNOPSIS
Weak front offshore moving inland Wednesday. This will mark the beginning of a cool and wet last week of April with an upper level trough over the area and a couple of systems moving through over the weekend and Monday. Snow levels will lower over the weekend to near 3000 feet Monday for possible snow on all the mountain passes the first part of next week.

SHORT TERM /TONIGHT THROUGH FRIDAY/
Satellite imagery shows some high clouds over Western Washington this afternoon.
Approaching front still well to the northwest over Northern Vancouver Island. Temperatures at 3 pm/22z were in the 60s and lower 70s.

Low level offshore flow will transition to onshore this evening with a weak surface ridge out ahead of the next frontal system.
Front moving slowly down from the northwest will still be offshore by 12z Wednesday. Rain out ahead of the front could reach the north coast early Wednesday morning. Increasing clouds overnight will keep low temperatures in the 40s.

Weakening front moving through Western Washington Wednesday. Front reaching the coast late morning moving through the interior in the afternoon before hanging up over the Cascades late in the afternoon. Not much in the way of rain with the front with most places getting less than a tenth of an inch. Main story for Wednesday will be the cooler high temperatures, 10 to 15 degrees cooler than Tuesday, in the mid to upper 50s.

Upper level trough over the area Wednesday night keeping a chance of showers in the forecast. Mostly cloudy skies and weak low level onshore flow will keep low temperatures in the mid to upper 40s.

Much more organized system moving into Western Washington Thursday with a half inch to an inch of rain along the coast with higher amounts over the Olympics and lesser amounts over the interior and the Cascades. Snow levels around 4500 feet so no snow in the lower passes. Highs Thursday remaining cool, in the mid 50s.

Front becoming a little negatively tilted with the associated surface low moving south along the coast. This will slow the eastward movement with frontal passage not until later Thursday night/early Friday morning. Another half to one inch of rain possible along the coast and in the Olympics with a quarter to a half inch elsewhere. Rainfall totals with this front will be about equal to the total rainfall so far for April in some places. Lows in the mid 40s.

Upper level trough moving over Western Washington behind the front Friday for more showers across the area. Not much in the way of cool air associated with the trough with snow levels remaining above 4000 feet. Highs Friday in the 50s.

LONG TERM /SATURDAY THROUGH TUESDAY/
Extended models in good agreement with a splitting front arriving over the weekend and another front on Monday. Very cool upper level trough settling into the area later Monday into Tuesday with 500 mb temperatures as low as -30C. Snow levels lowering to near 3000 feet Monday for the possibility of snow on all of the mountain passes Monday and Tuesday. Highs remaining below normal, in the 50s, with lows in the upper 30s to mid 40s. Felton

AVIATION
Winds aloft west-southwesterly as a broad upper-level trough approaches the area from the northwest. VFR conditions dominate for the majority of the TAF period for most locations. A blanket of high clouds will continue, with increasing mid to low level cloud cover tonight as a weak cold front approaches from the northwest. The best chances for MVFR ceilings are along the coast after 09-12Z Wednesday. Isolated IFR conditions may be possible Ceilings should be low-end VFR through the interior terminals, with a 20-25% chance of MVFR ceilings after 18Z Wednesday. Rain showers should be limited to the Pacific Coast and the north interior (BLI), but a few showers/drizzle may be possible through the remainder of the region Wednesday.

Winds generally west/northwesterly 5-10 kt. Winds decrease tonight and switch to southwesterly tonight. Winds will pick up in speed tomorrow morning back to 5-10 kt.

KSEA...VFR conditions expected through the TAF period. High clouds continue with increasing low-to-mid level cloud cover tonight. Winds WNW 5 to 10 kt in the afternoon before a transition to light southerly tonight. Winds increase back to 5 to 10 kt but remain SW tomorrow. A few showers are possible but should be light and not impactful.

MARINE
Weak thermal troughing continues to work onshore and dissipate as a weak front approaches the region from the northwest.
Winds will increase through the Strait of Juan de Fuca this evening, with the Small Craft Advisory for the Central and Eastern Strait of Juan de Fuca in effect through early tomorrow morning. The aforementioned front will approach the area early tomorrow morning but will dissipate as it does so, leaving only scattered showers and minimal impacts. A more substantial system will move through the area waters on Thursday, however, winds look to remain under advisory thresholds. A weak surface ridge will momentarily ease the winds for Saturday before an active pattern begins Sunday.

Seas look to remain 4 to 6 feet at about 10 seconds through the rest of the week and into Saturday.
