Recent National Weather Service and model consensus indicate a northeast flow behind a frontal passage has advected cooler, drier air into North Texas, capping daytime heating on October 4, 2026. Afternoon observations and short-range guidance show temperatures peaking near 78–80 °F under partly cloudy skies with light showers and 5–10 mph northeast winds, limiting insolation and surface warming relative to the 83.9 °F climatological high. This pattern aligns with the market’s heaviest weighting on the 78–79 °F bin, while the modest probability on 80–81 °F reflects residual uncertainty in cloud cover and any late-day clearing. Updated model runs through the evening will refine the exact maximum before resolution.
