...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR FAR SOUTHERN
ALABAMA AND THE WESTERN FLORIDA PANHANDLE...

...SUMMARY...
A couple tornadoes are possible beginning Wednesday afternoon
through Wednesday night over parts of the central Gulf Coast states
in association with Zeta.

...Central Gulf Coast...
Tropical cyclone Zeta will approach the coast and subsequently move
inland during the period.  The influx of a tropical airmass
(characterized by mid 70s surface dewpoints) will gradually spread
inland over southeast LA and the immediate coastal areas of MS/AL/FL
Panhandle during the day.  Forecast soundings show hodographs
enlarging initially over southeast LA and later along the MS/AL/FL
Panhandle coasts by late afternoon.  Sufficient buoyancy and
enlarged hodographs (0-1 km SRH 300-600 m2/s2) will probably yield
the development of several mini supercells in the outer bands of
Zeta.  It appears the greatest tornado risk will be confined to far
southern AL and the FL Panhandle where larger CAPE (500-1000 J/kg)
and SRH will spatiotemporally overlap.  Considerable uncertainty
remains how far inland a low/conditional supercell-tornado risk will
develop late overnight (i.e., east-central AL and adjacent parts of
GA).
