..no severe thunderstorm areas forecast... 

thunderstorms will be possible over portions of the central and 
southern Great Plains Thursday and Thursday night...however severe 
storms are not anticipated. 

A large-scale upper trough over the western U.S. Will remain 
positively-tilted with a belt of strong middle-level flow extending 
across the desert SW northeastward through the central states and into the 
Great Lakes. In the low levels...a cold front aligned from the southern 
High Plains to the upper Great Lakes will push southeastward into west-central Texas 
and the middle MS valley. The poleward transport of the moisture over 
the Southern Plains will contribute to weak instability despite 
widespread clouds. Weak impulses forecast to shear northeastward across the 
Southern Plains will aid in shower/thunderstorm development especially 
beginning late Thursday and into Thursday night near and north of the 
front over the Southern Plains. The anafrontal character of the front 
will promote the predominate tendency for storms to become elevated. 
Adequate effective shear would support updraft organization with the 
stronger updrafts and the possibility for small hail with the 
stronger storms but the marginal instability will act to limit the 
overall threat.
