Areas affected...Louisiana
Concerning...Tornado Watch 110...
Valid 022013Z - 022145Z
The severe weather threat for Tornado Watch 110 continues.
SUMMARY...Threat for a few strong tornadoes will persist next couple
hours with discrete storms developing through central LA. In
addition, the squall line may pose a risk for a few QLCS tornadoes
as well as significant wind damage and hail as it advances east
through LA.
DISCUSSION...Discrete supercells continue to mature as they develop
north and interact with warm front across central LA where VWP data
show large low-level hodographs with 0-1 km storm relative helicity
from 300-400 m2/s2. Tornadoes, a few of which will be strong, will
remain likely with these storms this afternoon. Farther west a
squall line is advancing east at around 40 kt. Organized structures
continue to be observed within the line including bowing segments,
embedded supercells and mesovortices. In addition to damaging wind,
QLCS tornadoes are likely as the squall line continues east and
especially where the line intersects the warm front across central
LA.
