..no severe thunderstorm areas forecast... 

severe thunderstorms are not expected over the U.S. On Thursday. 

..cntrl Appalachians through middle Atlantic area... 

Surface low initially over the Ohio Valley 12z Thursday will develop eastward 
into the northestern states by evening while trailing cold front advances 
southeastward through the Tennessee Valley. A warm front will move northward through the 
middle-Atlantic region. Corridor of widespread showers will likely 
shift from the Ohio Valley through the middle Atlantic and northestern states 
along warm conveyor belt and within pre-frontal confluent regime. 
However...prospects for deep convection will remain limited due to 
meager instability resulting from limited moisture return and weak 
middle-level lapse rates. A few lightning strikes will be possible with 
some of the pre-frontal convection...but updrafts will remain 
shallow with thermodynamic profiles through the convective layers 
only marginally sufficient for thunderstorms.
