Recent National Weather Service and model guidance indicate persistent southerly flow and high humidity will limit overnight radiative cooling for Houston on October 13, supporting minimum temperatures most likely in the mid-70s°F. Scattered showers and thunderstorms expected during the day may increase cloud cover and alter local cooling rates, creating uncertainty across forecast runs. This aligns with market-implied odds clustered evenly across the 72–81°F range, reflecting trader assessment of subtle variations in wind, dew points, and precipitation timing rather than any shift toward extremes. Historical October climatology shows similar warm, moist patterns often yield overnight lows near 74–78°F absent a stronger frontal passage. Updated model guidance ahead of the date will refine these thresholds.
