Recent National Weather Service and model guidance indicate a high near 88–92°F for Houston on October 13, driven by a warm, humid air mass with southerly flow off the Gulf sustaining above-average October temperatures. Afternoon showers and thunderstorms, expected with 40–60% probability, introduce modest cooling potential through cloud cover and evaporation, aligning with the market’s concentration on the 90–93°F range. Persistent southeast winds and heat indices above 100°F reflect ongoing late-season warmth, while model consensus and historical analogs support limited upside beyond the mid-90s absent stronger subsidence. Updated NWS briefings and afternoon model runs will refine these probabilities before resolution.
