**Current NWS forecasts point to a high near 98°F for Dallas on August 2 under mostly sunny skies and a light northerly breeze.** This aligns with the closely matched market leaders at 96–97°F (39.5%) and 98–99°F (32.5%), which together capture the bulk of trader probability. The primary drivers are a strong surface high-pressure ridge promoting subsidence and clear conditions, combined with a shift from southerly Gulf moisture advection earlier in the week to northerly flow on Sunday. This pattern typically caps daytime heating by a few degrees compared with peak heat days (such as the 100–104°F readings expected the prior day). Model consensus from the National Weather Service favors this trajectory, though small differences in boundary-layer mixing, exact wind speeds, or residual humidity can shift the maximum by 1–2°F. Historical late-summer climatology for Dallas shows daily highs averaging around 96–99°F in early August, providing context for why the market clusters tightly around these bins rather than extremes. Traders are weighting the latest model runs and guidance updates, with any new NWS or NOAA forecast revisions likely to influence the tight spread between the top two outcomes.
