**Forecast models from the National Weather Service and NOAA ensembles currently favor a daily high of 96-97°F in Houston on August 15, 2026, aligning with the market’s leading 59% implied probability for that bin.** Typical mid-August conditions in the Houston area feature strong solar heating under a subtropical high-pressure regime, combined with high Gulf moisture that limits overnight cooling and supports daytime maxima in the mid-to-upper 90s. Recent forecasts show mostly sunny skies with only isolated afternoon shower chances, allowing temperatures to reach or slightly exceed the seasonal average high near 95°F. The 94-95°F bin at 27.5% reflects possible modest cooling from sea-breeze effects or thin cloud cover, while the 11% chance assigned to 98-99°F accounts for the small upside risk if heating strengthens under the ongoing heat dome. Historical August data indicate that 100°F+ readings remain uncommon without stronger subsidence or drier air, keeping those tail outcomes below 1%. Updated model runs through the morning will refine these probabilities ahead of peak heating.
