....DISCUSSION...
....Tuesday/Day 4 to Thursday/Day 6...
Southwest flow at mid-levels is forecast to shift from the Great
Plains and Mississippi Valley on Tuesday to the Ohio and Tennessee
Valleys by Thursday, as an upper-level trough remains in the
vicinity of the Four Corners and southern Rockies. Ahead of the
trough on Tuesday, a moist airmass is expected to be in place over
the Texas Coastal Plain and lower Mississippi Valley. The moist
airmass is forecast to move eastward across the Gulf Coast states on
Wednesday and Thursday. Scattered thunderstorms will likely develop
over parts of the moist sector each day. However, instability is
forecast to be weak, suggesting that any severe threat will be
isolated and marginal.

....Friday/Day 7 and Saturday/Day 8...
On Friday, the moist airmass is forecast to shift eastward to the
southern Atlantic Seaboard, where isolated to scattered
thunderstorms will be possible on Friday and Saturday. Instability
is expected to be very weak suggesting convection will remain
unorganized Friday into Saturday.
