...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
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.
