   Valid 191200Z - 201200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected Sunday over the continental United
   States.

   ...Discussion...

   In the wake of a strong surface cold front, a generally cool, dry,
   and stable airmass will continue to filter southward across the
   eastern United States on Sunday. Although surface dewpoints will be
   in the 60s along and ahead of the front across the Florida
   Peninsula, weak convergence along the front and warm temperatures
   aloft should preclude thunderstorm development.

   Elsewhere, shallow convection associated with lake-effect
   precipitation may have the potential for a couple of lightning
   strikes, but confidence and coverage is too low to justify
   delineation. Additionally, as a low-amplitude mid-level trough moves
   across the Pacific Northwest, sufficient cooling aloft may result in
   enough mid-level instability to produce a lightning strike or two
   along and near the immediate coast.
