Current forecasts from the National Weather Service and major models indicate an overnight low near 79°F for Houston on August 30 under mostly clear to partly cloudy skies, light southerly winds, and elevated dew points near 70–75°F that restrict radiative cooling. This supports the market's leading 78–79°F outcome at 34% while leaving room for modest downward revisions toward 76–77°F if skies clear more than expected. Persistent warm, humid air masses have kept recent minima elevated above the late-August climatological average of around 75°F. Key variables differentiating the closely matched bins include any last-minute shifts in cloud cover, boundary-layer moisture, or local urban heat effects that could alter the precise minimum by 2–4°F. Updated model runs overnight will refine these thresholds ahead of resolution.
