..no severe thunderstorm areas forecast... 

isolated to scattered thunderstorms will be possible on Saturday 
from the southern Great Lakes southward to the Gulf Coast states and 
arklatex. Additional thunderstorms will also be possible from the 
Desert Southwest northward into the central and northern rockies. 

An upper-level ridge will build north-northeastward into the northern plains on 
Saturday as an upper-level trough moves eastward across the Great Lakes 
and MS valley. As surface temperatures heat up during the day near the 
upper-level trough...isolated to scattered thunderstorms will be 
possible from the southern Great Lakes southwestward into the Ozarks and southward 
across the Ohio and Tennessee valleys. Scattered thunderstorms will also 
develop in the Desert Southwest and Four Corners region related to 
surface heating and topographic forcing. Due to weak deep-layer shear 
profiles and poor lapse rates...severe thunderstorms are not 
expected across the Continental U.S. On Saturday or Saturday night.
