Areas affected...portions of central Louisiana into Mississippi

Concerning...Severe Thunderstorm Watch 277...

Valid 122043Z - 122145Z

The severe weather threat for Severe Thunderstorm Watch 277
continues.

SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 277. Severe hail and damaging gusts remain possible into the
evening hours.

DISCUSSION...MRMS mosaic radar imagery depicts multiple
multicellular structures and supercells ahead of a surface cold
front over central LA into MS, where 50 dBZ echoes have exceeded 40
kft in some storm cores. Furthermore, MRMS MESH has depicted storms
with hail approaching 2 inches in diameter, with a couple of 1 inch
hail/wind damage reports also received. Given the heated, well-mixed
boundary layer (and associated 3500+ J/kg MLCAPE) preceding the
storms, supercell structures should persist into the evening hours
with a large hail/damaging gust threat.
