**Current National Weather Service forecasts and ensemble model consensus point to an overnight low in the upper 70s (around 76–79°F) for Houston on September 28, driven by persistent southerly flow, high humidity, and the absence of any frontal passage or significant cooling mechanism.** Recent climatological data show typical late-September minimums near 72–75°F, but the current pattern features above-normal warmth with dew points in the low-to-mid 70s and light winds that limit nocturnal radiational cooling. No tropical moisture or storm systems are expected to alter temperatures before the 28th, keeping the daily minimum well above the 67°F threshold and far below any 86°F extreme. Updated model runs through the weekend will refine the exact value within the 74–80°F range, where market resolution hinges on official observations from Houston-area stations.
