Official observations from the Dallas Love Field station, as reported by the National Weather Service (NWS), confirm a maximum temperature of 78-79°F on April 15, driving the market's 100% implied probability for that outcome and near-certainty among traders risking real capital. This matched pre-event NWS forecast consensus around 78°F under an upper-level ridge fostering southerly winds, partly cloudy skies, and moderate humidity that capped peak heating near the historical April 15 average of 77°F at the site. While inherent forecast uncertainty from cloud cover variability or timing of breaks could have nudged outcomes toward 76-77°F or 80-81°F, finalized data eliminates realistic challenges barring rare post hoc quality control revisions to sensor readings.
