**Official National Weather Service observations recorded a daily maximum of 95°F at Dallas/Fort Worth on September 26, 2026, directly anchoring the market’s 100% implied probability on the 94-95°F outcome.** Clear to partly cloudy skies, light southeast winds, and dew points in the low-to-mid 60s permitted efficient daytime heating under late-September solar angles, pushing temperatures 8–9°F above the 1991–2020 normal high of 86°F. No significant cloud cover or precipitation interfered with peak insolation during afternoon hours. The result aligns with recent model consensus and station data from Love Field and DFW Airport. A realistic challenge would require an official data revision or a switch to an alternate reporting station showing a meaningfully different maximum, though both remain low-probability given the consistency across primary sources.
