GFS/ECMWF ensembles project ATL highs max 89°F. Synoptic ridging insufficient for 92°F thermal exceedance. Outlier probability negligible. 90% NO — invalid if GFS/ECMWF 00z runs shift mean >2F.
ECMWF ensembles project Atlanta's May 5 high firmly below 90°F, with no sustained upper-level ridge. Zonal flow and potential shortwave passage limit extreme warm advection. Market overestimates early-May heat potential. 90% NO — invalid if GFS flips to +3 sigma anomaly.
