..no severe thunderstorm areas forecast... 


... 
isolated convective showers and a few thunderstorms are possible 
over Florida on Wednesday. 


... 
As a strong upper trough moves across the northeastern states, a 
large area of high pressure will move from the Central Plains toward 
the Ohio Valley, providing offshore surface winds across the Gulf and 
Atlantic coasts. A front will settle southward across northern Florida 
and the northern Gulf Coast, with weak instability forecast across 
Florida coincident with daytime heating. Temperatures aloft will be warm 
there due to the upper ridge, but weak surface convergence may 
result in a few deepening convective showers, with a few producing 
lightning. 


Elsewhere, an upper low will meander across Arizona and UT, but little if 
any instability will be present to support thunderstorm activity.
