Persistent late-summer heat across North Texas, driven by strong high pressure and southerly flow, produced observed highs of 100–102°F at Dallas-area stations on September 8, aligning closely with National Weather Service measurements of 102°F at DFW. Multiple forecast models and climatological analogs from recent heat waves supported expectations of peak readings near the upper end of the 100–101°F range before final verification. With the market-implied probability at essentially 100% for that bin, trader consensus reflects verified observational data and the low likelihood of rapid cooling or measurement revision. Only an unprecedented late-day temperature drop or station-specific anomaly would realistically shift resolution outside this outcome.
