Forecast models from the National Weather Service and other sources show clear skies and light southerly winds prevailing over Houston on October 11, limiting nocturnal radiative cooling and supporting minimum temperatures clustered in the mid-to-upper 60s°F. Slight differences in predicted boundary-layer mixing and dew-point advection across runs create the tight market spread, with traders weighting the potential for 63–65°F readings against warmer guidance near 70–73°F. Historical October climatology for the region favors lows around 65–70°F under similar high-pressure patterns, but the absence of strong frontal systems or cloud cover keeps resolution sensitive to the final evening observations and any last-minute model adjustments.
