Current forecasts from multiple meteorological sources indicate Atlanta's overnight low on October 1 will likely fall in the upper 60s°F under mostly clear skies and light southeast flow, well above the historical average of about 61°F. This stems from persistent high pressure and southerly advection of warmer air masses, with limited radiational cooling expected due to humidity and minimal wind. The near-even market split between sub-59°F and 78°F+ outcomes reflects model uncertainty in exact boundary-layer mixing and any late-day cloud increases that could alter overnight minima by several degrees. Upcoming National Weather Service updates and short-range ensemble runs will clarify whether steering patterns shift enough to allow greater cooling or sustain the warmth.
