...DISCUSSION...
A shortwave trough will advance across the southern Plains and lower
Mississippi Valley through the middle of the week, before reaching
the Southeast later in the week. As it does so, it will gradually
de-amplify, with an upstream trough following closely in its wake.
During the D4/Tuesday-D5/Wednesday period, the initial trough may
support isolated thunderstorms from eastern Oklahoma/Texas into
Arkansas. However, modest low-level moisture will support only weak
buoyancy, resulting in minimal severe potential. Thereafter, the
upstream trough may encourage more precipitation across the
Mississippi Valley and vicinity; however, a continued lack of
noteworthy theta-e recovery east of the Rockies should keep severe
potential low.
