Official forecasts from the National Weather Service and supporting models project a high near 91°F in Houston on October 1 amid southeasterly flow, elevated humidity, and an 70-80% chance of showers and thunderstorms. These conditions introduce cloud cover and evaporative cooling that temper peak heating while warm advection sustains values above the late-September average. Trader consensus, with 90-91°F holding the highest implied probability at 44.5%, aligns with this guidance, though storm timing and intensity introduce modest uncertainty that could shift the outcome toward 88-89°F or 92-93°F. Historical October highs average near 86°F, underscoring the current warmth. Updated model runs and NWS briefings in the next 48 hours will refine resolution criteria.
