National Weather Service forecasts confirm a daytime high near 70°F at Seattle-Tacoma International Airport (KSEA) under partly sunny skies and light winds today, driving trader consensus to a 100% implied probability for 62°F or higher as the overwhelming outcome. This positioning aligns with model consensus from NOAA guidance, showing ridging aloft and minimal marine influence allowing temperatures well above the mid-April climatological average of 57–63°F, where highs rarely dip below 50°F. Current observations already support steady warming into the afternoon. Realistic challenges include late-day thickening clouds from Puget Sound stratus or an unexpected onshore surge, though such shifts are unlikely per latest model runs; final resolution awaits Weather Underground's official KSEA high.
