**National Weather Service forecasts for Atlanta indicate a clear Tuesday night with light easterly winds, favoring strong radiative cooling and a projected minimum temperature near 56°F on October 6.** This aligns with the tight clustering of market-implied odds around the 56–61°F bins, reflecting trader focus on the narrow range between official guidance and minor model variations in overnight cloud cover or wind speed. Recent surface observations show dew points dropping into the upper 50s amid dry conditions, supporting efficient heat loss after daytime highs in the mid-70s. Historical October averages near 58–59°F provide context, but the current high-pressure pattern and calm regime tilt probabilities toward the cooler side of seasonal norms. Final NWS station readings at Hartsfield-Jackson will resolve the market within hours, with any last-minute forecast adjustments from the Peachtree City office likely to influence final positioning.
