**Forecast models from the National Weather Service and private sources point to an overnight low near 79°F for Houston on September 1 amid hot, humid conditions with a 40-50% chance of afternoon showers and thunderstorms.** Trader sentiment remains closely divided because a weak Gulf low-pressure area is increasing atmospheric moisture, which can limit nighttime radiative cooling when clouds persist. Clear periods would allow temperatures to drop toward the mid-70s through enhanced longwave radiation loss, while widespread cloud cover or rain-cooled air masses could hold the minimum in the upper 70s to low 80s. Recent model runs show minor spread in boundary-layer moisture and steering flow, keeping outcomes from 71°F or below through the low 80s competitively priced as the market weighs these thermodynamic and dynamic variables ahead of final observations.
