Recent National Weather Service forecasts for Atlanta point to an overnight low in the upper 60s on October 3 amid an approaching frontal system and widespread showers, keeping trader-implied odds near even between sub-64°F and 82°F-plus outcomes. Radiative cooling under variable cloud cover, combined with southerly flow and elevated dew points, limits how far temperatures can drop, while model disagreements on storm timing introduce uncertainty around the exact minimum. Historical October 3 lows average near 60°F but recent years have trended warmer, and any delay in cloud arrival or stronger winds could push readings higher. Updated NWS and GFS runs over the next 48 hours will refine the range before market resolution.
