   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE
   FLORIDA PANHANDLE AND NORTHERN FLORIDA INTO SOUTHERN GEORGIA...

   ...SUMMARY...
   Severe thunderstorms will be possible Tuesday over parts of the
   Southeast.

   ...Synopsis...
   An upper trough will be located over the mid to lower MS Valley
   Tuesday morning, and will proceed toward the TN Valley by 00Z.
   Substantial westerly mid and high level winds will exist across the
   Gulf Coast states, aiding shear. Meanwhile, a mean warm front will
   likely extend from the northeastern Gulf of Mexico across parts of
   northern FL and into southern GA early on Tuesday, with a northward
   progression expected into GA and SC during the day. The primary
   surface low will develop across the OH Valley, with a cold front
   into the MS Valley and western Gulf of Mexico.

   ...Southeastern States...
   Substantial uncertainty exists regarding the position of early-day
   storms, possibly from southern AL into the FL Panhandle. However,
   the environment ahead of the expected morning MCS will be quite
   supportive of severe storms, including damaging wind and conditional
   tornado risk. A swath of damaging winds appears likely with the
   early MCS given strong mean wind speeds and expected eastward motion
   along the instability gradient. Depending on how far outflow from
   the early storms moves south, additional afternoon storms could
   develop along such a boundary. This activity would likely be more
   isolated as large-scale ascent shift northeast.

   To the north, additional daytime storms are likely beneath the upper
   trough where cooler temperatures aloft will exist, from parts of KY
   across TN and into northern MS/AL/GA. Marginal hail will be possible
   with these cells as MUCAPE rises to perhaps 1000 J/kg.
