Forecasts from NOAA and local models show overnight lows for Houston on August 27 clustering around 80–82°F amid a persistent heat wave, with highs near 100°F the prior day limiting radiative cooling. Elevated dew points near 75°F, light southwesterly winds, and partial cloud cover from a 20–30% rain chance further suppress temperature drops, while urban heat retention adds several degrees. Ensemble spreads and minor variations in steering patterns or shower timing create the tight clustering of market-implied odds around the 80–83°F bins, with lower-probability outcomes reflecting scenarios of clearer skies or brief convective cooling that could push readings into the mid-70s or mid-80s. Historical August averages near 76°F underscore how anomalous recent conditions have elevated the floor.
