Areas affected...2Southeast Louisiana and southern Mississippi

Concerning...Severe potential...Watch unlikely=20

Valid 111938Z - 112115Z

Probability of Watch Issuance...5 percent

SUMMARY...A few strong storms with gusty outflow winds possible the
next few hours.

DISCUSSION...In advance of a remnant MCV and the primary shortwave
trough over east TX, ascent is increasing across southern LA this
afternoon. Thunderstorms have already developed in southwest LA,
and should continue to expand eastward along a slow-moving front
into southeast LA and southern MS through the afternoon. Surface
temperatures have only warmed slowly as a result of persistent
clouds, but boundary-layer dewpoints near 70 F are supporting MLCAPE
of 1000-1500 J/kg with minimal convective inhibition along the
boundary. Though deep-layer shear appears sufficient for organized
storms at first glance, regional VWPs show very weak flow in the
lowest 3-4 km AGL. Thus, the potential for severe/persistent storms
will remain marginal and limited to isolated downbursts with
precipitation loading and/or melting of small hail.
