Official forecasts from the National Weather Service and other models indicate clear skies and light winds over Dallas on October 10, supporting an overnight low near 66–68°F under a stable high-pressure regime. This setup favors moderate radiational cooling after daytime highs in the upper 80s, with dew points in the upper 50s to low 60s limiting further temperature drops. Market-implied odds cluster around the 68–69°F bin at 51% because ensemble guidance shows little deviation from this range, while the 47% probability assigned to 76°F or higher reflects residual uncertainty in boundary-layer mixing or subtle warm advection. Lower bins near 58–63°F carry lower implied probabilities due to the absence of stronger northerly flow or cloud cover that would enhance cooling. Updated model runs and surface observations through the evening of October 9 will be the key near-term drivers.
