National Weather Service forecasts from NOAA indicate Seattle's high temperature today will reach near 70°F under mostly sunny skies, driven by a weak ridge of high pressure suppressing onshore flow and allowing daytime heating, aligning with trader consensus implying 96% odds for 66°F or higher at Sea-Tac Airport. Ensemble model guidance supports this, with minimal cloud cover and light northwest winds limiting marine layer persistence after morning burn-off. Historical May averages hover around 65°F, making this positioning climatologically plausible amid current upper-level ridging. Realistic challenges include unexpected strengthening of cool Puget Sound stratus or a sudden frontal intrusion, though latest 06Z model runs show low probability; monitor hourly observations and afternoon updates for shifts.
