Current forecast models from the National Weather Service and global ensembles indicate persistent southerly flow from the Gulf of Mexico will maintain elevated overnight lows in the mid- to upper-70s°F for Dallas on September 29, driven by warm advection, high humidity, and limited radiational cooling under mostly cloudy skies with a slight shower chance after midnight. This setup aligns with late-September climatology under neutral ENSO conditions but leaves room for model spread on exact minimums depending on timing of any boundary-layer mixing or unexpected cloud breaks. Trader consensus reflected in the near-even odds for 67°F or below versus 86°F or higher captures this short-range uncertainty in steering patterns and precipitation impacts, while narrower buckets around 76-77°F show lower implied probability amid the binary extreme focus. Updated model runs and NWS briefings ahead of resolution will clarify whether subtle shifts in wind or moisture alter the floor.
