   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Isolated thunderstorms are possible across south Florida on Sunday
   but severe thunderstorms are not expected.

   ...Synopsis...
   Broad upper troughing is forecast to be in place across the central
   and eastern CONUS early Sunday morning. A pair of shortwave troughs
   are expected to progress throughout this upper troughing. The lead
   shortwave will likely weaken as it moves across the Southeast, while
   the second shortwave matures towards a more negative tilt as it
   moves across the Great Lakes, OH and TN Valleys, and Mid-Atlantic.
   At the same time, western CONUS ridging will dampen as a pair of
   shortwave troughs move through its northern periphery ahead of an
   approaching upper low.

   A dry, continental air mass will cover the majority of the CONUS,
   precluding the moisture and buoyancy needed for thunderstorms. The
   only exception is across south FL, where enough low-level moisture
   may exist for a few thunderstorms amid the weak convergence near the
   front.
