Persistent humidity and cloud cover from scattered showers kept overnight radiative cooling limited across the Houston area on September 10, 2026, supporting market-implied odds near 50% for a low of 78–79°F versus 72–73°F. Official observations recorded a minimum of 79°F amid south winds near 5 mph and dew points in the mid-70s, consistent with the elevated baseline typical of early September when subtropical moisture and weak steering patterns suppress clear-sky cooling. Model consensus had shown limited diurnal range under the unsettled regime, with recent days posting lows in the upper 70s rather than the climatological 74°F average, narrowing the window for colder outcomes while leaving room for minor station or timing variations in final verification.
