..no severe thunderstorm areas forecast... 


... 
scattered thunderstorms are expected to develop on Wednesday across 
the Appalachian Mountains...Gulf Coast states and along much of the 
eastern Seaboard. Scattered thunderstorms should also develop in the 
Desert Southwest eastward into the Rocky Mountains. Isolated 
thunderstorms will be possible across the Mississippi Valley...Great 
Lakes region...Ohio and Tennessee valleys and in the northcentral 
states on Wednesday afternoon. 


An upper-level ridge is forecast to amplify across the upper Midwest 
and western Great Lakes region on Wednesday as southwest flow remains in 
place across the northwestern third of the nation. Warming surface temperatures on 
Wednesday should result in scattered thunderstorms in the Desert 
Southwest eastward into the Rocky Mountains aided by topographic forcing. 
Scattered thunderstorms are also expected to develop Wednesday 
afternoon in a moist airmass across Florida...the Gulf Coast 
states...southern Appalachians and Carolinas. Due to limited 
deep-layer shear across the Continental U.S....no severe thunderstorm activity 
is expected Wednesday or Wednesday night.
