**Persistent high-pressure ridge centered over the southern Plains is keeping Dallas under hot, dry conditions with clear skies and southerly flow, limiting overnight radiative cooling.** Official NWS Dallas/Fort Worth guidance and ensemble models point to a Monday night low of 80–82 °F for August 31, consistent with recent multi-day forecasts showing minimal change in the 100–103 °F daytime maxima and dew points in the mid-60s. This places the market-implied probabilities for the 80–81 °F and 82–83 °F bins near parity, reflecting typical short-range forecast uncertainty of ±2 °F in the absence of frontal passages or significant moisture advection. Historical August 31 lows average near 75 °F, but the ongoing late-summer heat anomaly supports the current trader consensus around the upper 70s to low 80s. Updated model runs and the next NWS area forecast discussion are the key near-term catalysts.
