Trader consensus on Polymarket reflects near-certainty (100%) for Dallas's highest temperature on May 4 reaching 72°F or higher, aligned with National Weather Service (NWS) forecasts indicating a high near 84°F under mostly sunny skies and south winds of 10-20 mph gusting higher. This positioning stems from a persistent high-pressure ridge over Texas fostering adiabatic warming, ample solar insolation after a clear morning with temperatures already climbing from the low 60s, and seasonably warm air masses consistent with NOAA's spring outlook for above-normal temperatures. Model consensus from recent runs shows no significant cloud cover or frontal boundaries disrupting daytime heating. Realistic challenges would require an unforeseen marine inversion, sudden thunderstorm outflow, or measurement anomaly at official stations like Dallas/Fort Worth International Airport, though current guidance deems these improbable with resolution imminent by evening.
