Area Forecast Discussion National Weather Service Seattle WA 210 AM PDT Tue May 21 2024

SYNOPSIS
A frontal system and trailing upper trough will lead to cooler and wet conditions across Western Washington today into Wednesday. Weak ridging aloft will produce drier and somewhat warmer weather on Thursday before another trough arrives Friday into Saturday for a return of cooler, unsettled conditions. A trend toward drier weather and more seasonable temperatures is possible early next week.

SHORT TERM /TODAY THROUGH THURSDAY/
Clouds are increasing across the CWA early this morning ahead of a frontal system pushing southeastward down the British Columbia coast. Rain will reach coastal areas before sunrise then spread across most of the interior by late this morning. A cold front will sweep onshore late this afternoon with rain turning to showers this evening. QPF remains fairly high for late May with the much of the lowlands expected to pick up a half inch to an inch of rainfall. Post- frontal onshore flow ramps up this evening and this should get a convergence zone going for a few hours over Snohomish/King Counties.

The trailing upper trough shifts southeastward across the area during the day on Wednesday. This will keep showers and cool temperatures in the forecast across interior areas, though the focus for the precip should be mainly in the Cascades by Wednesday afternoon. Snow levels will dip to 3500 to 4000 feet in the Cascades, but impactful snowfall is not expected in the higher passes. Much like yesterday, upper ridging centered well offshore briefly noses in the area for drier and slightly warmer conditions on Thursday.

LONG TERM /FRIDAY THROUGH MONDAY/
Another trough is slated to drop into the region Friday into Saturday for more showers and cool temperatures. There are signs of a shift in the synoptic pattern thereafter, but how this ultimately will play out is uncertain.
Broad upper troughing over the western third of the country is expected to be replaced by a strengthening ridge early next week while a large trough takes up residence south of the Aleutians.
Of course, Western Washington is caught between the two. So, it's a question of which one will have the greater influence. The latest suite of global ensembles have weakly positive height anomalies over Western Washington Sunday into Memorial Day. At a minimum, this suggests that temperatures will return to near seasonal normals by the end of the holiday weekend with best precip chances retreating to the Olympic Peninsula. If football is a tale of two halves, the weekend weather may be much the same.

AVIATION
Mostly VFR, except for MVFR/IFR along the coast as precipitation moves inland from the NW. Stratiform rain and lower/MVFR ceilings will spread across the region throughout the morning, with localized IFR possible in heavier showers that develop throughout the day. Conditions will improve by the evening with post- frontal convergence zone showers possible late Tuesday evening that could impact KPAE/KBFI/KSEA. Lighter onshore flow will continue through the morning with stronger southerly flow 5-15 kt developing by the afternoon. West to southwest winds increasing to 10-20 kt by Tuesday evening with gusts to 25 kt mainly for KHQM/KCLM.

KSEA...VFR conditions early this morning with increasing cloud cover. MVFR conditions and rain beginning around 13Z-14z, becoming heavier into the early afternoon and clearing by 22/04z. Convergence zone showers may linger into the early morning hours Wed but models favor any development to stay north of KSEA/KBFI. S/SW flow will develop through the morning with winds 10-15 kt through the afternoon with gusts to 20 kt. Southwest winds are favored to stay elevated into Wed morning with lower/MVFR ceilings persisting.

MARINE
Small Craft winds will continue through the Strait of Juan de Fuca through the early morning. A strong frontal system will cross the waters on Tuesday, boosting winds to SCA both offshore and through the Strait of Juan de Fuca through the evening and into Wednesday. Seas will rise above 10 ft across the offshore waters by Tuesday evening and continue rise to as high as 16 ft by Wednesday especially over the northern coastal zones. Waves will be steep with short period waves dominating. Another frontal system may pass through area waters on Friday, bringing elevated seas and breezy winds.
