   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
   LA/MS/AL AND THE FL PANHANDLE...

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE GULF
   COAST STATES...

   ...SUMMARY...
   A couple of brief tornadoes and/or isolated damaging winds will be
   possible this afternoon and tonight across southern portions of
   Louisiana and Mississippi into Alabama and the Florida panhandle.

   ...Portions of LA/MS/AL and the FL Panhandle...
   While considerable cloud cover persists over much of
   central/northern portions of MS into AL, modest
   moisture/destabilization could allow for a low-end isolated damaging
   wind and/or brief tornado risk through the afternoon/early evening.

   Farther south, a somewhat more focused severe risk may exist along
   the immediate Gulf Coast this afternoon into this evening, including
   parts of southeast Louisiana to far southern portions of MS/AL and
   the FL panhandle. While existing cloud cover and ongoing inland
   convection cast some uncertainty regarding the effective northward
   extent of appreciable destabilization inland, considerable mass
   response should occur in tandem with an amplifying upstream trough
   over the southern Plains to ARKLATEX. Accordingly, as gradual/modest
   destabilization occurs especially immediately near the coast,
   increasing forcing for ascent and strengthening deep-layer/low-level
   winds could support semi-organized storms modes near the coast later
   this afternoon into tonight. At least a localized damaging wind and
   a brief tornado threat will exist in these areas.
