Area Forecast Discussion National Weather Service Seattle WA 835 PM PDT Sun Apr 21 2024

UPDATE
A few showers are lingering this evening, mainly in the central Cascades. Otherwise, clearing skies will continue tonight where clouds linger in the central Puget Sound. Temperatures tonight will drop into the mid 30s to low 40s for areas of patchy frost, mainly in the East Puget Sound Lowlands and Southwest Interior areas.

SYNOPSIS
Drier conditions beginning tonight with upper ridging building over the area through early this week. Temperatures will warm through Tuesday. Troughing will develop over the area later Wednesday into the weekend for more unsettled weather.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/...Showers continue this afternoon with westerly flow aloft as an upper trough moves east of the area and ridging begins to build offshore. Showers will dissipate this evening into tonight, before cooler, drier conditions into Monday morning. Clearing skies, along with lighter winds, will allow lows to drop into the mid 30s to low 40s. A Frost Advisory remains in effect for the East Puget Sound Lowlands, as well as portions of the Southwest Interior, with temperatures likely ranging 33 to 37 degrees into Monday morning.
Make sure to bring sensitive plants indoor, or cover them.

Ridging will build further across Western Washington on Monday for dry conditions, and warming temperatures. Generally clear skies are expected on Monday. Clouds will begin to increase Monday night into Tuesday with increasing southwesterly flow as the ridge axis moves eastward. However, dry conditions are expected to continue into Tuesday given the ridging influence. Highs on Monday will warm into the upper 50s to mid 60s, with highs warming to near 70 for some areas on Tuesday.

Onshore flow will increase Tuesday night into Wednesday with troughing developing across British Columbia. Precipitation chances also increase on Wednesday given the proximity of the trough. Clouds and increased shower chances will usher in cooler temperatures with highs in the mid to upper 50s.

LONG TERM /THURSDAY THROUGH SUNDAY/...Troughing will develop further over the Pacific Northwest Thursday through Saturday.
Unsettled weather during this period is expected with increased precipitation chances and periods of light mountain snow.
Uncertainty begins to increase on Sunday, however, the majority of ensembles suggest troughing develops again offshore for continued precipitation chances, although at this time precipitation amounts are not significant. Temperatures during this period will likely lean a few degrees below normal given troughing over the area. JD

AVIATION
Northwest flow aloft expected into Monday with the air mass gradually drying as weak upper ridge moves into the region.
Low level onshore flow will relax overnight and become northerly on Monday. Isolated showers this evening will dissipate and skies will clear overnight as subsidence associated with upper ridge takes over.

KSEA...Last remnants of convergence zone activity will end by around 05Z with skies clearing overnight. Surface winds northerly less than 10 knots will become light northeasterly toward morning. Northerlies will pick up Monday afternoon to 10 to 15 knots at times by around 20Z. 27

MARINE
Surface ridge centered just offshore will weaken on Monday as thermally induced low pressure expands northward across Western Oregon. This will result in northerly flow on Monday that will become weakly offshore later Monday into Monday night. Northerlies over the coastal waters may approach small craft advisory thresholds, but are currently capped at 20 knots.
The next frontal system arrives around Wednesday, but appears to have little in the way of potential headlines. A somewhat stronger system on Thursday may generate a broader set of headlines...especially over the coastal waters. All in all, a fairly quiet beginning to the week is expected. 27

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

SEW WATCHES/WARNINGS/ADVISORIES
WA...Frost Advisory until 8 AM PDT Monday for East Puget Sound Lowlands-Hood Canal Area-Lower Chehalis Valley Area- Southwest Interior.

PZ...Small Craft Advisory until midnight PDT tonight for Central U.S.
Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.
