Watch issuance is not expected. DISCUSSION...Growing cumulus and the early stages of thunderstorm development are noted across portions of southeast GA into adjacent areas of SC. This activity comes as diurnal heating erodes inhibition head of a weak mid-level perturbation (the remnants of an early-morning MCS) that is approaching the region. Thunderstorm intensification and coverage should slowly increase as weak ascent ahead of the perturbation overspreads the region and daytime heating continues to bolster buoyancy (MLCAPE values are expected to reach around 3000-3500 J/kg). Very weak deep-layer wind shear will limit storm longevity and intensity, but steepening low-level lapse rates near 8.5 C/km will favor accelerating downdrafts and strong downburst with swaths of damaging winds (most likely peaking between 40-60 mph). Given the poor kinematic environment and the isolated nature of the threat, watch issuance is not expected. ..Moore/Hart.. 07/27/2026 ...Please see www.spc.noaa.gov for graphic product...
