   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTH
   FLORIDA...

   ...SUMMARY...
   A strong to severe thunderstorm or two may occur this afternoon
   across the southern Florida Peninsula, with damaging wind gusts and
   marginally severe hail possible on an isolated basis.

   ...South Florida...
   Will maintain low severe probabilities for a seemingly limited, or
   at least uncertain, potential for a strong/locally severe storm or
   two this afternoon. Overnight showers and a few thunderstorms
   continue to drift eastward away from the southeast Florida Peninsula
   around daybreak. Lingering cloud cover should break/thin into the
   afternoon with minimal inhibition within a seasonally moist
   environment. South Florida will remain south of the
   southward-sagging synoptic cold front. However, a sea breeze could
   influence the development of a few thunderstorms across the
   southeast Florida Peninsula late this afternoon, within a regime
   otherwise characterized by weak forcing. If inland development
   occurs/matures this afternoon, adequate instability and a moderately
   long/semi-straight hodograph (upwards of 35-40 kt effective shear)
   might support marginally severe hail and/or gusty winds.
