National Weather Service forecasts and ensemble model guidance from NOAA indicate a high temperature near 85°F in Dallas on May 22, driven by southerly flow and above-average warmth consistent with the agency’s spring outlook for the southern Plains. Partly sunny conditions with a 30 percent chance of afternoon thunderstorms are expected to limit extreme heating but still support readings solidly above 80°F, aligning with the market’s 91 percent implied probability for that threshold. Historical May climatology for the region shows typical highs around 84°F, providing additional context for the strong trader consensus. A realistic challenge would require unexpectedly widespread cloud cover or heavy rainfall to suppress temperatures into the upper 70s, though current guidance shows limited downside risk through the overnight period.
