National Weather Service surface observations at LaGuardia Airport and Central Park recorded a daily maximum temperature of 76–77°F for New York City on May 16, aligning with the market’s near-certain 100% implied probability for that bin. Model guidance from the GFS, ECMWF, and NAM converged on modest southerly flow and limited mixing under partly sunny skies, keeping peak heating well below the May climatological average of 72–75°F. This outcome reflects verified thermometer readings rather than forecasts, with resolution criteria tied directly to the highest hourly value at the designated stations. Only an undocumented station calibration error or post-event data revision could alter the result at this stage.
