…NO THUNDERSTORM AREAS FORECAST…
…SUMMARY…
Severe thunderstorms are not expected across the contiguous U.S.
through tonight.
…Discussion…
Convection continues to diminish/move offshore across south Florida,
with a few showers lingering near the Keys at this time. However,
with minimal risk for additional lightning, the 10% thunder area is
being removed at this time. Appreciable thunder risk is not
apparent across the U.S. the remainder of the period.

…South FL…
Isolated thunderstorms will remain possible, mainly along a weakly
convergent pre-frontal confluence band that should progress east
across the remainder of the peninsula this afternoon. With veered
low-level flow nearly paralleling the confluence axis and relatively
warm 700-600 mb temperatures, convection should struggle to
appreciably intensify. An organized severe risk is not expected.
