Trader consensus overwhelmingly favors a high temperature of 70-71°F in Atlanta on March 28 (98.5% implied probability), driven by the latest National Weather Service (NWS) forecast models—including GFS and NAM—converging on this range amid a persistent high-pressure ridge over the Southeast. Clear skies, light southwest winds around 5-10 mph, and low humidity (20-30%) are enabling efficient diurnal heating from overnight lows near 50°F, aligning with late-March climatological normals of 69°F at Hartsfield-Jackson Atlanta International Airport (KATL), the official measurement site. A recent cold front passage on March 27 stabilized conditions after an earlier warm spell, reducing uncertainty. Realistic challenges include unexpected high cloud cover capping insolation for a 68-69°F outcome or stronger solar heating pushing into 72°F+, with hourly observations through afternoon providing final clarity before daily resolution.
