...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected today.

...Synopsis...
Cyclonic flow aloft will continue to prevail across all but the West
Coast States today, with the axis of the primary trough to shift
eastward across the eastern third of the country through the period.

At the surface, a cold front trailing southward across the western
Atlantic from a low initially over the Canadian Maritimes, will move
gradually southward across the Florida Peninsula and Gulf of Mexico.
The front should clear southern portions of the Peninsula and the
Keys by around midnight.  Elsewhere, high pressure will prevail
across the U.S. in the wake of the frontal passage.

Showers and a few thunderstorms are expected across parts of
Florida, near and to the cool side of the front.  Modest CAPE, weak
low-level flow, and the slightly elevated nature of most of the
convection should preclude severe weather potential.

A flash or two of lightning may also occur in lee/east of the Lower
Great Lakes, as cold air aloft overspreads the relatively warm lake
water resulting in low-topped convective snow bands.  However,
coverage of any lightning should remain quite sparse -- insufficient
to warrant introduction of a thunder area.
