Current National Weather Service and private model guidance for Dallas on July 20 points to a daily high near 100–102 °F under typical late-July conditions of high pressure, light winds, and abundant July sunshine. These values align with the historical climatological range for the date, where Dallas-Fort Worth averages roughly 98–101 °F, modulated by the urban heat island effect and soil moisture from recent rainfall. Ensemble spread remains modest, supporting the market’s heaviest weighting on the 100–101 °F bin, while modest upside risk from any westward ridge strengthening keeps the 102–103 °F tier as the next most probable outcome. Updated model runs and the official NWS forecast discussion tomorrow morning will provide the final inputs before resolution against the KDFW observation.
