Valid 191200Z - 201200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast across the contiguous United
States on Friday.
...Synopsis and Discussion...
An upper trough will continue to move quickly northeastward across
the Mid-Atlantic and New England on Friday. At the surface, a front
will extend over the Gulf of Mexico, FL Peninsula, and into the
western Atlantic. North of this front, surface high pressure will
dominate much of the eastern states through the period. The only
appreciable chance for thunderstorms Friday will be across parts of
east-central and south FL, where greater low-level moisture will be
present south of the front. Poor lapse rates and weak instability
should greatly limit the potential for severe convection. Elsewhere,
thunderstorms are not expected across the rest of the CONUS due to a
lack of sufficient moisture and instability.
