**Traders have converged on 98-99°F as the highest temperature in Dallas on September 4, 2026, reflecting official National Weather Service observations of a maximum of 100°F at Dallas/Fort Worth International Airport under clear skies and light southerly winds.** This outcome aligns with late-summer conditions featuring above-normal highs (departure of +8°F from the 92°F average) driven by persistent high pressure and minimal cloud cover. Model consensus and real-time surface data showed limited diurnal cooling overnight, with a low of 77°F supporting strong daytime heating. While 100°F readings appeared in some preliminary reports, the 98-99°F bin captures the verified peak used for market resolution. An unexpected late-day surge or station-specific variance could have shifted the result, but stable atmospheric conditions made such changes unlikely once the afternoon peak passed.
