**Trader sentiment for the highest temperature in Dallas on August 13, 2026, centers on 100–103°F, with 100–101°F at 41.5% implied probability and 102–103°F at 31.5%.** This reflects model consensus and climatological norms for mid-August in North Texas, where the long-term average high sits near 96–101°F. Current conditions feature a dominant high-pressure ridge supporting sunny skies, southerly flow, and low humidity, with recent NWS and AccuWeather guidance pointing to daytime maxima of 100–105°F. The slight edge for 100–101°F aligns with the most probable range in ensemble forecasts, while the 102–103°F bucket captures upside from stronger mixing or localized heating. Lower probabilities for 98–99°F or 104°F+ indicate limited support for cooler intrusions or extreme heat spikes, as no major heat dome or atypical steering patterns have emerged in the latest runs. Traders are weighting official observations from Dallas/Fort Worth stations and the stability of the warm pattern through the 13th.
