Recent National Weather Service and model guidance point to a post-frontal setup with northerly winds and clearing skies after earlier showers, favoring radiative cooling overnight into October 4 and supporting a Dallas minimum in the mid-to-upper 60s. Ensemble forecasts show modest spread around 63–70 °F, driven by variables such as exact wind speeds (which limit boundary-layer mixing), residual moisture affecting dew-point depressions, and the timing of cloud dissipation. Historical October 4 lows average near 63 °F, so current conditions sit slightly above normal yet remain sensitive to small shifts in steering flow or urban heat retention. This uncertainty keeps the 80 °F-or-higher and 61 °F-or-below outcomes nearly tied while concentrating trader interest on the narrower 2 °F bins near the expected range.
