Persistent extreme heat and model consensus drive trader sentiment toward overnight lows in the low-to-mid 80s°F for Dallas on August 22. National Weather Service forecasts and ensemble guidance indicate mostly clear skies with south winds of 5–10 mph, limiting radiative cooling after daytime highs near 106–110°F. Warm advection from the Gulf, elevated dew points around 65–70°F, and minimal cloud cover or precipitation keep surface temperatures elevated overnight. Historical August averages near 77°F underscore the anomaly, while slight model variations in boundary-layer mixing and exact wind speeds create the tight clustering around 82–87°F bins. Traders weigh these factors against any late forecast shifts from updated runs.
