...no severe thunderstorm areas forecast...
...summary...
severe thunderstorms are not expected on sunday.
...discussion...
an amplified large-scale trough will move eastward from the great
lakes to the northeast on sunday, while a related cold front moves
off the eastern seaboard. despite poor deep-layer lapse rates, a
narrow corridor of diurnal heating amid lower/middle 60s dewpoints
(higher over the fl peninsula) ahead of the front should support
isolated thunderstorms from the coastal carolinas southward across
parts of the fl peninsula. weak/narrow buoyancy profiles will limit
thunderstorm intensity and the severe risk.
