Recent National Weather Service guidance for Dallas on May 17 forecasts a daytime high near 90°F, driven by southerly flow advecting warm, moist air ahead of a weak front. Ensemble output from the GFS and ECMWF models shows consensus around 86–89°F depending on the timing and coverage of afternoon thunderstorms, which could limit peak heating through increased cloud cover. This places the 88–89°F bin as the market leader at 56.5% implied probability, with 86–87°F a close second, reflecting traders’ assessment of typical May climatology where Dallas averages 85°F highs yet can reach the upper 80s under clear to partly cloudy conditions. Minor upward revisions in short-range model runs have modestly lifted odds for 90–91°F while keeping sub-86°F outcomes below 1%.
