**Current NWS forecasts for Atlanta on September 28 show mostly clear skies and light northerly winds, promoting strong radiative cooling overnight and supporting a minimum temperature in the mid-50s°F.** This places the outcome near the middle of the distribution, well above the 47°F threshold and far below 66°F. Clear, dry conditions under high pressure allow efficient heat loss from the surface, while the northerly flow advects slightly cooler air; any increase in cloud cover or shift to southerly winds could limit overnight cooling and raise the low. Model consensus remains tight two days out, though small timing or boundary-layer errors could shift the exact minimum by a few degrees. Historical September lows average near 62°F, so the current outlook reflects a modest cool anomaly driven by the post-frontal environment.
