Current forecasts from NOAA and private models indicate Houston's overnight low on September 16 will likely settle in the upper 70s to low 80s under mostly clear to partly cloudy skies, with light southeast winds limiting radiational cooling and high humidity sustaining elevated minimums. This setup aligns with typical late-summer patterns where dew points near 75°F suppress sharp overnight drops, keeping readings well above the 72.5°F historical average low but far from either extreme tail. Trader equilibrium between sub-71°F and 90°F+ outcomes reflects model uncertainty around any late-arriving frontal boundary or unexpected cloud cover, though consensus guidance shows limited potential for significant deviation before resolution. Updated model runs and NWS briefings over the next 48 hours will clarify steering patterns and boundary-layer moisture that determine the final minimum.
