Forecast models from the National Weather Service and local analyses indicate Houston will see mostly sunny skies and strong daytime heating on August 15, supporting market-implied odds favoring a 96-97°F peak at 40.5% over 94-95°F at 33.5%. Key variables include sea-breeze timing, which can cap inland maxima near the coast, variable afternoon dew points around 75-78°F that limit additional warming, and any thin high clouds that reduce insolation. Ensemble guidance shows only marginal spreads in maximum temperatures, reflecting typical mid-August variability where small shifts in steering flow or boundary-layer mixing can swing the daily high by 2°F. Recent observations confirm persistent upper-90s readings with minimal overnight cooling, keeping traders focused on the narrow range between these two bins while assigning lower probability to 98°F+ outcomes absent stronger subsidence.
