Area Forecast Discussion National Weather Service Seattle WA 214 PM PDT Thu Apr 25 2024

SYNOPSIS
Rain will turn to showers across Western Washington tonight as a weakening frontal system moves across the area. A few showers will remain into Friday as an upper trough remains over the region. A series of fronts will maintain wet conditions and below normal temperatures well into the coming week.

SHORT TERM /TONIGHT THROUGH SUNDAY/
It's a damp and cool afternoon across Western Washington as a weakening front moves into the area. Rain will turn to showers overnight as a trailing upper trough moves onshore. Showers will diminish by Friday afternoon into Friday evening as low amplitude upper ridging pushes into the coastal waters. The ridge flattens quickly by Saturday morning as the next in a series of fronts arrives.
Precip coverage will increase on Saturday, but the overall QPF will be lighter than that of today. Another front arrives Sunday afternoon into Sunday night. Snow levels in the Cascades generally stay in the 4000 to 5000 foot range through the weekend.
With unsettled conditions in place, temperatures will remain below seasonal norms throughout Western Washington.

LONG TERM /MONDAY THROUGH THURSDAY/
The extended forecast period begins much the same as the short term with another front spreading precip across the area Monday into Monday night. More uncertainty creeps into the day to day forecast details Tuesday and beyond. The overall pattern remains unsettled heading into the middle of next week as the mean trough position remains over the Pacific Northwest. However, the flow is looking increasingly zonal by that point in time. This results in considerable timing differences amongst deterministic model runs as well as noteworthy differences between the height anomalies in the ensemble means.
So, while it looks to remain unsettled, temperatures and PoPs may begin to edge at least a little closer to seasonal normals by late next week. 27



AVIATION
WSW flow aloft with broad troughing across the region.
Widespread rain across the region in association with a low pressure system. A mixed bag of ceilings across the region, largely MVFR or lower. Low visibility in heavier rain this morning, but visibility has been improving this afternoon. Ceilings should lower again tonight to low-end MVFR to isolated IFR tonight as rain continues.
Visibility may be restricted at times in heavier rain. A return to widespread VFR conditions is not expected until tomorrow afternoon, at the end of the TAF period.

Winds generally southerly, ranging from 5 to 15 kt, particularly gusty along the coast. Winds remain southerly throughout the period, though gradually decreasing to 5 to 10 kt tomorrow.

KSEA...MVFR to low-end VFR this afternoon with rain. Ceilings should be largely MVFR through most of the TAF period. A few periods of IFR ceilings cannot be ruled out, especially overnight tonight and early tomorrow morning. Rain should decrease in coverage to showers beginning tonight. Low ceilings continue through tomorrow, with VFR ceilings returning mid-day tomorrow. Winds primarily southerly, 5 to 10 kt.

MARINE
A low pressure system and associated cold front is located just offshore of western Washington and will continue to work its way through the region tonight into tomorrow. Winds across the area will ease down tonight. A weak surface ridge will move through Saturday morning but will be quickly followed by another front on Saturday afternoon. The active pattern continues into next week with additional systems moving through. While conditions will be breezy, widespread additional headlines are not expected with winds staying around or just below Small Craft Advisory thresholds.

The Small Craft Advisory will end for the coastal waters south of Point Grenville this afternoon, and for the East Strait of Juan de Fuca and Admiralty Inlet early this evening.

Seas 6 to 8 ft at 10 s continue through the end of the week, rising to 8 to 10 ft by Sunday and into the beginning of next week.
