SPC MD 311MD 0311 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTHERN FLORIDA PENINSULA...SOUTHEASTERN GEORGIA...EASTERN SOUTH CAROLINA...FAR SOUTHERN NORTH CAROLINA
Mesoscale Discussion 0311 NWS Storm Prediction Center Norman OK 0322 PM CDT Wed Mar 27 2024
Areas affected...northern FLORIDA Peninsula...southeastern Georgia...eastern South Carolina...far southern North Carolina
Concerning...Severe potential...Watch unlikely
Valid 272022Z - 272215Z
Probability of Watch Issuance...20 percent
SUMMARY...Thunderstorm coverage will increase this afternoon with potential for instances of severe hail and wind.
DISCUSSION...Thunderstorm development has begun in eastern Georgia near a surface boundary that extends from the Carolinas southward into the eastern Florida Panhandle. CAMs continue to suggest this thunderstorm activity will increase into the afternoon, with scattered thunderstorms expected across much of the region. Afternoon heating has been slow, given mid-to upper level cloud cover and slow eroding of stable air behind morning convection. Surface objective analysis indicates MLCIN has weakened with around 500 J/kg MLCAPE across South Carolina into Georgia ahead of the boundary. This trend is further confirmed by thunderstorm development on radar.
Currently, deep layer shear is strongest across the northern Florida Peninsula into southern Georgia. As the front shifts eastward this afternoon, stronger mid-level flow will spread northward, with deep layer shear increasing to the north as a result. This will support potential for a few more robust thunderstorms with potential for damaging winds and large hail. Given the slow air mass recovery and potential for messy storm mode with multi-cell clusters, a watch is unlikely to be needed this afternoon.
