Area Forecast Discussion National Weather Service Seattle WA 846 AM PDT Thu Jun 20 2024

SYNOPSIS
A upper level ridge offshore will continue to build into the region through Friday. The ridge will shift east of the area on Saturday. An upper level trough moving into British Columbia on Sunday will produce cloudier and cooler conditions along with a chance of showers. Weak upper level ridging will bring a modest warming trend and generally dry conditions for much of the area early next week.

SHORT TERM /TODAY THROUGH SATURDAY/
Mostly clear skies prevail across Western Washington early this morning with the exception of some patchy stratus along the central coast. Gradually rising heights and light northerly flow near the surface will translate to 2 to 4 degrees of warming for most of the region...which puts most of the interior from Seattle southward into the 80s today.
Minimum RH will dip down in to the low 30s to mid 20s through the Southwest Interior. Weak troughing aloft will probably produce a few cumulus buildups near the North Cascade crest this afternoon, but any thunderstorm potential is likely to remain east of the crest.

Heights continue to rise into Friday for a little additional warming across interior areas, but increasing low level onshore flow late in the day should cool coastal areas a few degrees.
The upper ridge axis shifts east of the area Friday night.
Temperatures will cool a few degrees on Saturday as an upper level trough approaches, but interior locations should squeeze out one more seasonably warm day. Onshore flow ramps significantly Saturday night with a likely deepening marine layer and some drizzle or light showers developing along the coast.

LONG TERM /SUNDAY THROUGH WEDNESDAY/
An upper level trough is expected to more onshore over southern British Columbia on Sunday.
This will bring us clouds and significant cooling along with a few showers...especially coast, mountains, and within a convergence zone over Snohomish County. The trough washes out fairly quickly as it pushes eastward on Sunday. Recent model ensembles as well as deterministic runs are now trending a little warmer and drier for the early part of the coming week. This is likely due to some subtle changes in the synoptic pattern as upper ridging broadens its influence over the western U.S. in response to the eventual demise of a strong ridge downstream over the northeastern U.S.

27/LH

AVIATION
Weak upper level trough over Western Washington this morning will shift east this afternoon into tonight. Light westerly flow aloft becoming northwesterly this afternoon. In the lower levels light onshore flow into Friday.

IFR stratus along the central and south coast getting as far east as the Lower Chehalis Valley this morning before dissipating around 18z. Clear skies for the remainder of the area. Low clouds with IFR ceilings reforming along the central and south coast after 06z tonight.

KSEA...Clear skies through the TAF period. Northeast wind 6 to 10 knots becoming northwesterly 8 to 12 knots around 21z. Winds shifting back to northeasterly 6 to 10 knots after 05z.

MARINE

System moving through Saturday with increasing onshore flow behind the system Saturday night. Gales likely in the Central and Eastern Strait of Juan de Fuca with small craft advisory winds in the adjacent waters. Weak surface high pressure over the coastal waters Sunday through Monday night with onshore flow weakening into the first part of next week.
