Recent forecast model runs show notable divergence in Atlanta's overnight low for October 5, with National Weather Service and private guidance ranging from the upper 50s to upper 60s amid a post-frontal clearing trend after heavy rain on October 4. Radiative cooling under partly cloudy skies and lighter northeast winds could drive temperatures toward or below 59°F if dew points fall sufficiently, while residual moisture and cloud cover may hold readings in the mid-60s. This uncertainty, set against October climatological normals near 55–60°F, explains the near-even market-implied odds between sub-60°F and 78°F+ outcomes alongside the clustered mid-range probabilities, with traders weighting the latest model consensus and surface observations ahead of final resolution.
