Current forecasts from the National Weather Service and major models indicate Houston's lowest temperature on October 13 will likely fall in the mid- to upper 70s, driven by persistent southerly flow advecting warm, humid Gulf air with minimal overnight radiational cooling under partly cloudy skies and scattered thunderstorm activity. This aligns with seasonal norms for early October in the region, where average lows hover near 65°F but recent patterns show elevated baselines from above-average Gulf sea surface temperatures. Trader sentiment remains dispersed across the 72–81°F bins because ensemble guidance shows modest spread in cloud cover timing and any weak frontal influences that could nudge the minimum by a degree or two. Updated model runs and NWS point forecasts expected over the next 24–48 hours will likely narrow resolution criteria around the official minimum observation.
