Areas affected...Southeast LA and coastal MS

Concerning...Tornado Watch 713...

Valid 020338Z - 020445Z

The severe weather threat for Tornado Watch 713 continues.

SUMMARY...The threat for a tornadic supercell or two should increase
over the next couple hours across southeast LA, including the New
Orleans metro area.

DISCUSSION...Long-lived convective cluster across south-central LA
will likely continue east-northeast into the early morning hours
across southeast LA and coastal MS. An embedded supercell has
recently intensified over the Assumption Parish vicinity, and
additional supercell development will be possible to the southwest
of this storm amid strong mid to upper-level speed shear. Low-level
hodographs are also in the process of enlarging, albeit from
initially small curvature, and should continue to do so for the next
several hours. Time-series of the TMSY wind profile confirms 0-3 km
SRH has steadily held above 250 m2/s2 and a longer-lived supercell
may evolve out of the Assumption Parish storm as it approaches the
greater New Orleans/Lake Pontchartrain area through midnight.
