Areas affected...South-central Louisiana

Concerning...Severe Thunderstorm Watch 346...

Valid 210043Z - 210215Z

The severe weather threat for Severe Thunderstorm Watch 346
continues.

SUMMARY...Large hail and damaging wind gusts will remain possible
into the early evening in south-central Louisiana.

DISCUSSION...Large hail, with isolated reports greater than 2
inches, have been the main hazard in WW 346 over the last couple of
hours. Convection in southern Louisiana continues to push slowly
westward into the greater buoyancy. New updrafts along this linear
segment will remain capable of large hail and damaging wind gusts. A
cluster of supercell structures has been ongoing just south of
Alexandria. This activity has generally been moving slowly
southward. KPOE radar imagery shows outflow boundaries emanating
from these storms. Coincidentally, storms have appeared slightly
more disorganized as they have ingested this outflow. Capping
evident on the observed 00Z LCH sounding should keep this activity
from moving much more to the west. A threat for large hail and
damaging winds is expected to continue for another 2-3 hours.
