The overwhelming trader consensus favoring an 86-87°F high in Dallas on May 17 reflects the National Weather Service’s official observation, which aligned closely with ensemble guidance from the National Centers for Environmental Prediction. Stable high-pressure ridging kept skies clear and limited moisture return, producing a maximum temperature that remained within the typical mid-May climatological range for North Texas. Model runs showed tight clustering around 86°F with little spread, consistent with historical averages near 85°F for the date. Resolution could shift only if the National Weather Service issues a rare post-analysis correction or if micro-climate differences at official stations alter the recorded peak, though such revisions are infrequent for routine daily temperature data.
