...there is a marginal risk of severe thunderstorms across portions
of the southeast...
...summary...
isolated strong thunderstorms may produce damaging wind gusts across
portions of the gulf coast states/southeast on friday.
...southeast...
a series of mid/upper shortwave impulses will migrate across the
gulf coast states/southeast on friday. forecast guidance depicts
fairly strong 850 mb flow across the region early in the day, and
lifting shifting offshore from the carolinas by late afternoon.
while 850-700 mb flow will be enhanced, vertical shear will be
modest. nevertheless, convection will develop within a very moist
airmass amid moderate to strong instability ahead of a southward
sagging front. isolated strong/damaging gusts will be possible with
this activity.
