Area Forecast Discussion National Weather Service Seattle WA 201 AM PDT Wed May 8 2024

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
Northwest flow aloft will become more northerly today as an upper level ridge begins to build over the Pacific Ocean/Northwest through the end of the week. For Wednesday, there's a 40% chance of stratus developing this morning (as early as 13Z through 18Z) over northern Puget Sound terminals. At this time, models have the most likely scenario of these clouds forming on the lower-end VFR criteria for CIGs . A smaller chance exists for these clouds forming at MVFR (20-25%). Once temperatures warm, clouds will clear for the remainder of the day (with low stratus possible along the coast late tonight/Thursday morning). Winds will remain light out of the north at 5 to 10 kt.

KSEA...Morning stratus deck potentially forming in or around the terminal from 13-18Z Wednesday morning. Will most likely be VFR, but small chance it comes in as MVFR. Otherwise clear to mostly clear skies for the remainder of the TAF period. Winds north 6 to 12 kt.

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. A push of westerly winds through the central Strait of Juan de Fuca today may become gusty for small crafts - thus will continue the advisory in place for today. A couple inner waterways (Puget Sound and Admiralty Inlet) as well as the coastal waters may see gusty winds out of the north this afternoon between 15 to 20 kt (chance of winds exceeding this are extremely low). Remainder of the week will keep winds out of the north, with potential for breezy winds in the outer coastal waters this weekend to 15-20 kt.

Seas will fall to 6 to 8 feet today, and remain at this level through the forecast period.
