Recent National Weather Service and model guidance, including GFS runs, indicate clearing skies and northerly flow after early-week showers will support a high in the low-to-mid 80s for Dallas on October 5, with surface heating and light winds favoring the upper end of that range under mostly sunny conditions. Trader-implied probabilities remain closely split between 90 °F or higher and the 84–85 °F bin, reflecting residual uncertainty across ensemble members regarding peak boundary-layer temperatures and any late-day mixing. Historical early-October normals near 82 °F provide context, while the next 12–24 hours of updated short-range forecasts and observational trends will likely refine the market’s assessment ahead of resolution.
