A one-day warmup is in store with high pressure aloft bringing sunny skies on Wednesday. High temperatures will be in the 70s north and coast, with low to mid-80s around most of Puget Sound.
This will be the warmest day of the year by five to eight degrees (the warmest so far in Seattle was 77 degrees on May 6), but well shy of daily record highs.
The daily record for Wednesday in Seattle is 92 set in 1983, and my forecast high is 85.
We’ll cool down a bit for Thursday and Friday with highs in the upper 60s and low 70s, with a chance for rain showers on Thursday morning.
There could be a few isolated thunderstorms early Thursday morning through early Thursday afternoon in the Cascades and east slopes.
Following that slight chance for rain, the weekend looks quite nice with highs in the 70s for many and lows in the 40s to low 50s.
