Area Forecast Discussion National Weather Service Seattle WA 321 AM PDT Tue May 7 2024

SYNOPSIS
An upper level trough will exit the region today and a ridge of high pressure aloft will begin to build into the area on Wednesday. The upper ridge will 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 minor cooling trend Sunday into Monday.

SHORT TERM /TODAY THROUGH THURSDAY/
The convergence zone had shifted into King County as of 130 AM PDT this morning and will continue to gradually shift south and eastward before dissipating over the Cascades later this morning. A few showers will linger into the afternoon mainly over the mountains as the upper trough responsible for the recent cool, wet conditions finally shifts east of the area. And then the change begins. Upper ridging offshore begins to build into the area tonight and Wednesday.
Sunshine returns to the area on Wednesday as high temperatures rebound to near seasonal levels under the influence of the building ridge.

The upper ridge centered just offshore continues to build on Thursday as 500 millibar heights approach 580 dam for the first time since...well, I can't remember when. At the same time, thermally induced low pressure expanding northward along the Oregon coast reaches the area. This will turn the low level flow offshore with coastal areas experiencing a significant boost in temperature. Hoquiam and Forks should have no problem reaching the mid 70s (or higher) on Thursday afternoon. Interior areas will warm up as well...with lower to mid 70s common from the Seattle area southward.

LONG TERM /FRIDAY THROUGH MONDAY/
The upper ridge axis shifts onshore on Friday while the thermal trough remains oriented along the coast. This will likely be the warmest day for the coast
with highs reaching the lower to mid 80s
which is daily record territory. Plentiful sunshine will be found regionwide with mid 70s to mid 80s across the interior lowlands. Models have the thermal trough shifting inland by later in the day on Friday.
Coastal areas should see 15 to 20 degrees of cooling for Saturday, but the thermal trough will produce another warm day for interior locations. A weak system passing to our north is expected to dent the ridge Sunday into Monday. Aside from a slight chance of mountain showers near the Canadian border, conditions look to remain dry with temperatures in the 60s and 70s...still above seasonal norms for the time of year. 27
