**Persistent extreme heat and limited overnight cooling dominate forecasts for Dallas on August 25.** Official National Weather Service guidance and private models project an overnight low in the lower-to-mid 80s, with most runs clustering between 82–85°F under mostly clear skies, southerly winds of 5–10 mph, and a strong warm air mass. This setup suppresses radiative cooling typical for late August, when the 1991–2020 average low sits near 76°F. **Trader consensus around 84–87°F ranges reflects tight model agreement on minimal deviation from these conditions.** Slight spread in probabilities for 78–83°F bands accounts for possible minor forecast shifts from any unexpected boundary-layer mixing or brief cloud cover, while very low odds on sub-80°F or 90°F+ outcomes align with the low likelihood of significant changes this close to the date. Updated model runs and NWS briefings over the next 24 hours remain the key variables that could nudge resolution.
