Recent National Weather Service and local meteorological model consensus projects a daytime high of 73–75°F for Seattle on May 22 under sunny skies and a strengthening high-pressure ridge, well above the 64°F threshold. This aligns with the market’s 98.6% implied probability for 64°F or higher, as short-range ensembles show minimal spread and no significant marine-layer intrusion or onshore flow expected to suppress temperatures. Historical climatology places average May 22 highs near 65°F, but the current warm anomaly driven by subsidence and clear conditions reinforces trader confidence. Only an abrupt shift in steering patterns or unforecasted cloud cover could realistically push the reading below 64°F, though such deviations remain low-probability within the final 24-hour window.
