..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.
