Trader consensus on Polymarket tilts toward highs of 80-81°F (37.5%) for Atlanta on March 26, closely trailed by 82-83°F (28%) and 78-79°F (23.5%), reflecting tight forecast model spreads amid a strengthening upper-level ridge over the Southeast. National Weather Service guidance and NOAA's GFS/ECMWF ensembles project peak afternoon temperatures in the low-to-mid 80s under sunny skies and southwesterly winds of 5-10 mph, driven by warm air advection from the Gulf of Mexico; however, slight ensemble divergences introduce uncertainty, with cooler outliers tied to potential mid-level clouds or earlier frontal timing. Historical March averages hover near 66°F, but ongoing positive temperature anomalies boost warmth potential. Watch for 12z model updates today, which could refine land surface model depictions of urban heat in Atlanta.
