Area Forecast Discussion National Weather Service Seattle WA 227 PM PDT Sat Apr 27 2024

SYNOPSIS
The active weather pattern will continue into early next week as a series of fronts pass through the region. Snow is expected in the passes Sunday night into Monday. A trend toward temperatures closer to normal and somewhat drier conditions is expected during the later half of the coming week.

SHORT TERM /TONIGHT THROUGH TUESDAY/
Light precip continues to spread across the area this afternoon ahead of an occluded front that will dissipates as it moves onshore this evening. A few showers will linger over Western Washington overnight behind the front. An upper trough west of Haida Gwaii will dig southward into the region later Sunday into Monday for cool, showery conditions. The cooler temperatures aloft will destabilize the atmosphere enough for a slight chance of thunder as well as lower snow levels to most of the passes by Sunday night into Monday. Relatively warm ground temperatures may limit accumulations at Snoqualmie Pass. Nonetheless, higher Steven Pass may accumulate somewhere in the range of 5 to 7 inches over a 12 hour period (06Z-18Z Monday). Another shortwave arrives Monday night into Tuesday. The focus with the precip with that system may be a little further south...perhaps mainly the southern half of the CWA

LONG TERM /WEDNESDAY THROUGH SATURDAY/
Deterministic model runs have shown little to no run-to-run consistency for the long term forecast over the past couple of days. And this meshes well with the high degree of uncertainty expressed by the NBM during that time period. There's increasing confidence that we'll see a short break in the weather on Wednesday, but the forecast picture becomes increasingly murky Thursday through Saturday. Despite the fact that deterministic runs of the GFS/Euro have flipped from earlier solutions, some of the ensemble means (the Euro in particular)
maintain some positive height anomalies late next week. Current forecasts for late next week look awfully close to climatological norms...and that's probably not a bad approximation at this time.

AVIATION
West-southwest flow aloft through the TAF period as upper level troughing moves across the Pacific Northwest. A mix of IFR, MVFR, and VFR CIGs this afternoon with rain and showers pushing across the area. Any lingering VFR ceilings should lower tonight to mostly MVFR. S-SW surface winds for area terminals (W for KCLM)
between 8-12 kt. Gusts up to 20-25 kt are possible this evening as a front passes.

KSEA...VFR CIGs currently with rain showers along with a 30% chance of MVFR through the remainder of the afternoon. Rainfall may be steadier at times this evening as a front tracks over the terminal.
A gradual trend back to MVFR through the night is expected.
Southwesterly winds through the TAF period, with gusts to 20 kt possible through this evening. VFR should rebound into Sunday.

MARINE
A frontal system is currently moving into area waters. SCA are posted for most marine zones through this evening as the aforementioned front passes. Most should be allowed to expire tonight but a westerly surge through the strait will keep the advisory going for the central and east strait through early Sunday morning. Marginal wind gusts to SCA thresholds possible Sunday afternoon (35% chance) over the offshore waters with another round of Small Craft Advisories likely through the Strait with another afternoon push and possibly through the beginning of next week.

Seas 6 to 8 feet tonight and through much of the day Sunday. Seas look to increase to 8 to 10 feet Sunday night into Monday. Seas then remain below 10 feet Tuesday onward.

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