**The market's 100% consensus on an 88-89°F high for Houston on October 1 reflects official station observations confirming that peak, consistent with National Weather Service data from sites like George Bush Intercontinental Airport and Hobby Airport.** Atmospheric conditions featured a warm, humid airmass with southerly flow and limited cloud cover allowing daytime heating near the long-term average high of 86°F for the date, though slightly above recent climatology. Model guidance and real-time readings converged on this narrow range without significant variability from steering patterns or frontal passages. Because the market resolves on verified maximum temperature rather than forecasts, the outcome locked in once final daily summaries were released, with only narrow revision risks from station-specific microclimates or data quality checks.
