Area Forecast Discussion National Weather Service Seattle WA 919 AM PDT Thu May 2 2024

SYNOPSIS
Dry and mostly clear conditions paired with warmer temperatures through Friday morning. A cooler and wetter storm system will move into western Washington on Friday, and unsettled conditions will continue through the weekend and beyond.

SHORT TERM /TODAY THROUGH SATURDAY/
No planned updates and the current forecast remains on tap. 33

Previous discussion...Showers over southwest Washington will continue to shift southward early this morning as a surface low slides inland over Oregon. Wrap-around moisture poses a slight chance for showers over the Cascades this afternoon as the trough exits to the southeast. Otherwise, dry conditions and mostly clear skies will prevail today across western Washington as a ridge builds in overhead with a return to near- normal temperatures in the mid 60s.

The next weather maker will move into the Pacific Northwest Friday morning as a trough deepens offshore. A front will swing inland throughout the day, bringing in widespread precipitation with snow levels near 4500-5000 ft. Temperatures ahead of the front will peak in the upper 60s with some areas seeing a good shot at 70 degrees, but temperatures behind the front will cool off roughly 10-15 degrees. Steady precipitation will continue on into Saturday as the trough shifts inland with little break in shower activity.
A majority of the moisture with this system will fall over the Olympic Peninsula, with roughly 1 to 2 inches of rainfall. The lowlands and Cascades will see between half an inch and an inch, with lesser amounts northward towards the Canada border.
Temperatures Saturday will be limited to the mid 50s.

LONG TERM /SUNDAY THROUGH WEDNESDAY/
Forecast models have come into better agreement through the long-term, with cooler and wet conditions continuing into next week. The broad upper level low over the Pacific Northwest will continue to shift eastward towards the end of the weekend, spreading more wrap-around moisture across the region as another wet system approaches from the northwest. Snow levels are forecast to stay above pass level, and cool onshore flow under zonal flow will help maintain showers into Monday and Tuesday. Onshore flow will ease by mid-week, which may provide some brief relief to the rainy weather and allow temperatures to return into the 60s.

AVIATION
An upper level low will continue to sink southeastward across the Pacific Northwest today, while upper level ridging nudges into the northeastern Pacific. This will maintain northerly flow aloft. VFR conditions remain in place across the region early this morning. Satellite imagery shows some mid to high level cloud cover continuing to stream over portions of SW WA as a surface low offshore makes its way towards OR. Clearing across the region will continue from north to south through the morning hours. Latest NBM probabilistic guidance has a 15-20 percent chance of IFR conditions developing at KPWT between 12-15Z. Elsewhere, expect conditions to remain VFR through the TAF period. Surface winds will generally persist out of the north at 5 to 10 knots through the day, shifting to the south late tonight into early Friday.

KSEA...VFR conditions through the TAF period. Clearing skies expected by late morning. Northerly winds will see a slight uptick to 5-10 kt by mid morning and look to persist through the afternoon.
Winds will ease again by the evening hours and look to transition back to the south between 06-09Z Friday. Additional showers possible just beyond the present TAF period around 16Z tomorrow.

MARINE
A low pressure system offshore will continue to move southeast and push into Oregon later this morning. Weak high pressure will then rebuild over the area waters today for overall calm conditions. The next frontal system will move into the area waters Friday into Saturday, likely bringing small craft southerlies to portions of the area waters and gusty westerly pushes down the Strait of Juan de Fuca in its wake on Saturday.
Another system looks to arrive in the region late in the weekend and into early next week.

Combined seas across the coastal waters will generally hover between 3-5 ft through Friday, before increasing towards 6-8 ft over the weekend. Latest probabilistic guidance hints at a 50-60 percent chance of seas approaching 9-10 ft Monday night into Tuesday. 14

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