Southeast States

Other than trimming risk areas behind the sagging cold front, no important changes have been made to the ongoing forecast.

Southeast States

A well-defined surface baroclinic zone extends from southern LA/MS east-northeastward into parts of AL/GA/SC today. To the south of the boundary, a rather warm/moist and unstable air mass is present with dewpoints in the upper 60s and afternoon MLCAPE values of 1000-1500 J/kg. This will lead to occasional thunderstorms along the boundary through the day and into the evening. Low-level winds are veered, limiting convergence and vertical shear. However, occasional small bowing structures will be possible today capable of gusty or locally damaging wind gusts. Also, modest mid-level lapse rates and cool temperatures aloft might result in a report or two of hail. Refer to MCD #110 for further short-term details.
