Official National Weather Service forecasts for Atlanta on June 1 placed the expected daily high near the seasonal normal of 85°F, with model consensus centering on 84–87°F under partly cloudy skies and isolated afternoon thunderstorms that would limit surface heating. This alignment with climatological baselines and real-time guidance drove near-certain market-implied odds for the 84–85°F bin. Traders weighed historical June averages and the narrow uncertainty range in short-range models, which showed minimal potential for significant deviation. A rapid shift to clear, sunny conditions or suppressed convection could have allowed additional warming into the upper 80s, while heavier or earlier storms might have capped readings below 84°F, though neither materialized in the final observational data.
