   Valid 091200Z - 101200Z

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS MUCH OF SOUTHERN
   FLORIDA...

   ...SUMMARY...
   A few severe thunderstorms with damaging winds are possible morning
   through midday on Saturday across southern Florida.

   ...Synopsis and Discussion...
   A highly amplified pattern will exist on Saturday with an upper high
   over the West, and an extensive upper trough across eastern North
   America. A cold front will be located over central Florida Saturday
   morning, and will rapidly progress offshore by late afternoon. A
   moist air mass will exist ahead of the front, contributing to
   sufficient instability for a few severe storms. Damaging winds are
   most likely with the linear storm mode along the front. It should be
   noted that the likelihood of ongoing convection near the front lends
   some uncertainty as to the timing of frontal passage, as outflow can
   accelerate the boundary faster than expected.
