An upper trough will continue to amplify and build southward along
the West Coast, with preceding height falls over the Great Basin and
northern Intermountain West. Sufficient moisture will exist ahead of
a cold front, with marginal buoyancy supportive of isolated
thunderstorms later today and especially into tonight from the
Sierra and Great Basin toward the northern Rockies. A couple of
stronger storms could materialize, but severe storms are not
expected. Elsewhere, thunderstorms will also be possible across the
Upper Midwest and Lake Superior vicinity, in addition to Florida and
the Lower/Middle Mississippi Valley.
