...DISCUSSION...
An amplified upper trough over the Plains will move toward the MS
Valley on Tue/D4, with moderate southerly winds aloft from LA to the
Upper Great Lakes. A moist air mass will exist ahead of a cold front
which will move toward the lower to middle MS Valley, supporting
rain and storms from the Sabine Valley during the afternoon, and
into the TN Valley by Wed/D5 morning. This setup could favor
isolated strong to severe storms, with locally strong wind gusts.

For Wed/D5 into Thu/D6, the system may take on more of a negative
tilt, and moisture return will result in expanding precipitation
across the Southeast as interacts with an antecedent surface ridge,
which should minimize instability. Shear also looks to be marginal
with mainly unidirectional out of the south aloft.
