Valid 281630Z - 291200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast across the contiguous United
States through tonight.
...Synopsis...
An upper trough over the Northeast and Mid-Atlantic states will move
east into the western Atlantic and become increasingly displaced
from the Southeast U.S. A southward-moving cold front, evident in
visible satellite imagery over the Gulf Stream east of north FL,
will move across the FL Peninsula before becoming less defined and
decelerating as it encounters a sub-tropical airmass over south FL
and the Bahamian archipelago. Strong heating and modest buoyancy
will support isolated to widely scattered convection mainly along
this boundary during the afternoon and evening, fostered by both
convergence along the front and sea breeze boundary. Limited
buoyancy and weak shear will likely preclude severe thunderstorms.
