...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected across the contiguous United
States on Monday.

...Synopsis and Discussion...
Large-scale upper troughing will persist over the eastern states on
Monday, while upper ridging builds over the western CONUS. At the
surface, high pressure will dominate much of the CONUS, with
offshore low-level trajectories continuing over the majority of the
Atlantic and Gulf Coasts. The only appreciable thunderstorm
potential on Monday will be limited to parts of the central and
southern FL Peninsula. Here, a southward-moving cold front should
provide a focus for convective development. Even though mid-level
lapse rates will remain poor, there may still be enough instability
during the daytime hours for occasional lightning flashes with the
strongest updrafts along/south of the front. Weak deep-layer shear
is expected to preclude organized severe thunderstorm potential
across this region.
