**Forecast consensus points to an overnight low in the upper 70s to low 80s for Dallas on August 30, 2026, aligning closely with the market's near-even split between the 80-81°F and 82-83°F bins (each at 36% implied probability).** Official guidance from the National Weather Service and multiple models shows mostly clear skies, light south-southeast winds, and dew points in the upper 60s to low 70s, which limit radiative cooling and keep minimum temperatures elevated. Highs near 100–102°F during the day further support this range, as the thermal inertia from recent hot, humid conditions prevents sharper overnight drops. No incoming cold fronts or significant cloud cover are expected in the next 48 hours to alter the pattern. This setup reflects typical late-August climatology for north Texas, where August lows historically average in the mid-to-upper 70s but often run warmer during prolonged heat waves. The tight clustering of the top two outcomes captures minor forecast spread from model timing of the exact minimum and local variations across the Dallas area. Updated NWS or short-range model runs over the next day will be the key catalyst for any shifts in trader positioning before resolution.
