Recent observational data from the National Weather Service and Dallas-Fort Worth International Airport confirmed a daily maximum temperature in the 80-81°F range on May 20, driving the overwhelming 99.7% market-implied odds for that outcome. Mild southerly flow, moderate humidity, and limited daytime heating under partly cloudy skies prevented any significant climb toward the 82°F threshold, consistent with climatological averages for mid-May in North Texas. With resolution criteria tied to official climatological reports, only an unforeseen data revision or station-specific anomaly could realistically shift the result, though current model consensus and real-time measurements leave little room for such changes.
