..no severe thunderstorm areas forecast...
a few thunderstorms will be possible over the Florida Peninsula on
Wednesday, but severe weather is not expected at this time.
A slow-moving positive-tilt upper trough will continue through the
Gulf Wednesday. Plume of subtropical moisture will expand through
the Florida Peninsula downstream from this feature where low-level
dewpoints in the upper 60s will reside south of a quasi-stationary
front. Weak impulses embedded within the southwesterly flow regime
along with a weakly capped and moist environment should promote the
development of showers and a few thunderstorms. However, marginal
instability and weak flow in the lowest 3 km suggest organized
severe storms are unlikely.
