....DISCUSSION...
Medium-range model guidance shows an eastward progression of a
lower-latitude mid-level trough to the east of the Southeast
Atlantic coastal states early in the extended period.  A mid-level
ridge is forecast to shift east across the central U.S. by mid week
with a vigorous upstream mid-level disturbance.  Models differ on
the evolution of this shortwave trough as it moves east into the MS
Valley and eastern U.S. during the Thursday-Friday period.  As a
result, predictability of both moisture-return quality and important
mass features is uncertain at this time.  Nonetheless, some
potential for severe thunderstorms may focus over parts of the lower
MS Valley and Southeast U.S. late in the work week next week.
