Area Forecast Discussion National Weather Service Seattle WA 829 AM PDT Wed May 8 2024

UPDATE
High pressure will build inland through the rest of the week and into the weekend, kicking off a warming trend. The lowlands are on track to see temperatures in the 80s on Friday and Saturday with elevated overnight lows in the low to mid 50s. While air temperatures will be warm, water temperatures will still be cool enough to pose a safety risk. No updates to the forecast.

SYNOPSIS
A ridge of high pressure aloft will begin to build into the area today then strengthen toward the end of the week as thermally induced low pressure near the surface expands northward into the area. Dry conditions will prevail along with the warmest temperatures of the year thus far on Friday and Saturday. A weak system passing to the north of the area will bring a cooling trend early next week.

SHORT TERM /TODAY THROUGH FRIDAY/
Ridging at the surface and aloft is building into the region today. With plenty of sunshine today, temperatures will bounce back to near climatological norms. The upper ridge continues to strengthen on Thursday as low level northerly flow turns offshore in response to thermally induced low pressure expanding northward along the coast. High temperatures will warm several degrees on Thursday...especially along the coast where offshore flow will boost temps into the mid 70s to near 80. 70s will be common across interior areas from the Seattle area southward.

The upper ridge weakens slightly on Friday, but 500 millibar heights remain in the vicinity of 580 dam. Coastal areas are likely to see another round of warm temperatures before the sea breeze kicks in late and the thermal trough makes the jump inland.
Friday will be the warmest day thus far this year for much of the interior lowlands with 70s in the north interior and 80+ from the Seattle area southward.

LONG TERM /SATURDAY THROUGH TUESDAY/
A switch to onshore flow on Saturday will cool coastal areas some 15 to 20 degrees or so compared to Friday while interior areas remain warm with the thermal trough in place. Sunday and beyond, the ridge is expected to flatten as a couple of systems pass by to our north. The main effect will be to cool temperatures back to near or slightly above seasonal levels. With the exception of a few possible showers in the North Cascades, the remainder of the area looks to remain on the dry side. 27

AVIATION
Northerly flow aloft as ridging begins to build offshore and continues through the end of the week. An area of MVFR stratus extends from Skagit/Snohomish Counties towards the Cascades this morning, with patchy fog in river valleys, particularly the Chehalis River Valley. Otherwise, mainly VFR across the area.
Stratus and fog in these areas will clear through the morning with mainly clear skies this afternoon into the evening. Lighter northerly winds will increase this afternoon.

KSEA...VFR today with mostly clear skies. There remains a slight chance for a brief period of MVFR stratus between 16-18z. NE winds this morning will transition more N around midday, and increase towards 7 to 12 kts into this evening, before becoming NE again later this evening. JD

MARINE
High pressure will continue to build over the waters today, with a thermally induced area of low pressure moving up the coast, and advancing inland Friday. Westerly winds will increase again this afternoon into this evening for the central Strait of Juan de Fuca with a Small Craft Advisory in place. In addition, a SCA has been issued for the central and southern inner coastal waters this afternoon into this evening. Increasing northerly winds during this period will allow for gusts near 25 kt before winds slowly subside later tonight. Otherwise, primarily northerly winds through late week.

Seas of 5 to 8 feet will continue into the weekend. JD

HYDROLOGY
The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed.
