**Trader sentiment for the daily minimum temperature in Dallas on August 24, 2026, centers on the 84–89°F range, with 86–87°F and 88–89°F each at 40% implied probability and 84–85°F at 31%.** This reflects a persistent heat wave keeping overnight lows elevated well above the long-term average of ~76°F. Official National Weather Service and model guidance indicate mostly clear skies, south-southwest winds of 5–15 mph, and dew points in the upper 50s to low 60s, which limit radiative cooling after daytime highs near 107–109°F. The slight (≤20%) chance of late-night showers or thunderstorms introduces minor variability in cooling rates, but widespread clear conditions favor minima clustering in the mid-to-upper 80s. Historical precedent for such extreme heat episodes shows overnight lows often 8–12°F above climatology when daytime maxima exceed 105°F. Key resolution hinges on the precise timing of the daily minimum (typically just before sunrise) and any microscale differences in urban heat island effects or wind gusts at official reporting stations. Updated forecast runs and real-time observations through the night remain the primary near-term catalysts.
