...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
No severe thunderstorms are forecast across the nation today.
A large upper trough is present today over the central and eastern
United States. Scattered showers and a few thunderstorms are
expected to affect parts of TX/LA, as well as along the Carolina/GA
coast and the FL peninsula. Strong storms are possible just off the
immediate coast of both regions, with hail and gusty winds possible.
However, current guidance suggests the risk of severe storms moving
inland is low.
