**A strong high-pressure ridge over North Texas produced clear skies, light southeast winds, and well-above-normal temperatures on September 7, 2026, driving trader consensus toward the 100-101°F bin.** National Weather Service forecasts issued the day before and morning of the event consistently projected a daily maximum near 101°F at DFW Airport (normal high ~91°F), with a heat advisory in effect and heat-index values reaching 106-107°F amid dew points in the upper 60s to low 70s. This aligned with a broader multi-week warm spell featuring 40+ days at or above 100°F and a 53-day dry streak that limited evaporative cooling. Official post-event climate summaries recorded an observed high of 102°F, yet pre-close market pricing reflected the tight clustering of guidance around 100-101°F and the low likelihood of deviation beyond that narrow range under the prevailing synoptic pattern. Realistic challenges to this positioning would have required either a faster-than-expected frontal passage, higher-than-anticipated cloud cover, or an official station reading falling outside the 100-101°F window due to localized effects—none of which materialized in the verified data.
