GFS ensemble mean and ECMWF operational runs for ATL on April 29 show 850mb temps supporting surface highs of 74-76°F. A robust ridge axis building over the Southeast, coupled with sustained southerly advection, will ensure optimal boundary layer mixing. This synoptic setup strongly signals a thermal profile squarely within the target 74-75°F window, with minimal frontal influence expected. We see high model congruence. 90% YES — invalid if unexpected cirrus deck limits insolation.
