A National Weather Service forecast and supporting model guidance indicate the daily minimum in Houston on October 15 will occur overnight near 70–73°F under partly cloudy skies and light southeast-to-northeast winds. This range aligns with observed early-morning readings around 73–74°F and projected lows of 70–72°F, supporting the 79% market-implied probability for 72–73°F. An approaching cold front is expected to deliver sharper cooling Friday, but current conditions and consensus model runs show limited downside risk for today’s low, keeping probabilities for sub-70°F outcomes near 48% while rendering higher readings above 74°F negligible at 0.1%. Traders are monitoring the next NWS update for any revision in the overnight minimum.
