Area Forecast Discussion

855pm PDT Wednesday August 4 2021

Synopsis
Upper level ridge over the area tonight moving east Thursday. Weak front approaching the area Thursday night and moving through Friday for a chance of light rain. A few disturbances moving through during the weekend have the potential to create some additional showers. Conditions will be drying out once again next week. We could see another warm up mid to late next week.

Short Term - Tonight Through Saturday
Satellite imagery shows stratus moving onshore along the north coast and still right along the coastline on the central and south coast. Clear skies over the remainder of the area this evening. Temperatures at 8 pm/03z were in the mid 60s near the water, 70s to lower 80s away from the water.

Forecast in good shape tonight. Increasing onshore flow overnight with the stratus getting down the Strait of Juan de Fuca into Western Skagit and Snohomish county. To the south the stratus getting into the south Puget Sound area. Aloft upper level ridge beginning to shift east. Lows tonight in the 50s.

Combination of the upper level ridge moving out of the area, approaching upper level trough and a little stronger onshore flow will result in a slightly cooler day across the area. In general highs 5 to 10 degrees cooler with the warmest locations in the mid 80s.

Weak front moving into the area Thursday night into Friday for a chance of rain. Best chance will be in the Cascades. Another weak system arriving Saturday keeping the chances for rain going into the weekend. Felton

Long Term - Sunday Through Wednesday
Previous discussion follows. Western Washington could continue to see some showers on Sunday as a trough moves through the area. However, things will begin to dry out later in the day and through the rest of the week. For Tuesday onward, ensembles are suggesting another ridge could build into the area. While there is still uncertainty, it is looking like we could be in store for some more hot days in Western Washington. That said, it will be very dependent on where exactly the ridge is situated.

Marine
Onshore flow will continue tonight and Thursday. Gale force west winds are occurring this evening in the Central Strait of Juan de Fuca and East Entrance. These winds will ease to small craft advisory strength after midnight tonight. Another round of gales is expected in the Strait Thursday night.

There are also small craft advisory westerly winds spilling into the adjacent Admiralty Inlet area this evening. These winds should ease later tonight but then another similar round of wind is expected Thursday evening. Small craft advisory strength northwest winds for the southern two thirds of the inner Coastal Waters will ease late this evening.

A weak frontal system will move through the area Thursday night and Friday. Winds over the Coastal Waters will briefly turn more southerly on Thursday ahead of this system. A couple of trailing weather disturbances will move through the area over the weekend. Schneider
