**Trader consensus strongly favors 78-79°F as the lowest temperature in Dallas on October 13, 2026, with 94.9% implied probability.** This positioning reflects National Weather Service forecasts and observational data showing a daily minimum near 78°F under persistent southerly flow, partly cloudy skies, and dew points in the low-to-mid 70s that limit overnight radiative cooling. Model consensus from GFS and local analyses maintains highs near 91-93°F with minimal temperature drops after sunset, consistent with late-summer warmth lingering into mid-October. A realistic challenge would require an unforecasted increase in cloud cover, higher winds, or precipitation that enhances cooling beyond current projections, though probabilities for such shifts remain low given stable atmospheric conditions and the day’s advanced stage.
