..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.
