Areas affected...portions of central and southern Georgia

Concerning...Severe Thunderstorm Watch 79...

Valid 252035Z - 252200Z

The severe weather threat for Severe Thunderstorm Watch 79
continues.

SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 079. Damaging gusts and large hail are the main threats. A
local WW extension in time is planned.

DISCUSSION...Multiple strong to potentially severe supercell
thunderstorms continue to progress across Severe Thunderstorm Watch
079. MRMS mosaic radar imagery - 7 km CAPPI depicts an overall
increase in storm intensity across the watch, with an increase in
the number of storms with 30 dBZ exceeding 40 kft also noted. These
storms are benefiting from a boundary layer experiencing maximum
diurnal heating, overspread by a plume of 7 C/km mid-level lapse
rates, contributing to widespread 2000+ J/kg MLCAPE. Despite
departing deep-layer ascent, 40-50 kts of effective bulk shear
remains across the warm sector as 80+ kts of 500 mb flow from an
associated jet streak glances the region from the north. As such,
supercell structures may persist and continue supporting mainly a
damaging gust/large hail threat through the remainder of the diurnal
heating cycle. Since Severe Thunderstorm Watch 079 expires at the
top of the hour, a local extension in time is planned to address the
persisting severe threat.
