Areas affected...northeast Louisiana into central Mississippi

Concerning...Severe potential...Watch likely

Valid 281840Z - 281945Z

Probability of Watch Issuance...80 percent

SUMMARY...The potential for large hail and damaging winds appears to
be increasing across the discussion area. A few tornadoes are also
possible. A WW is likely.

DISCUSSION...A cluster of thunderstorms has recently intensified
across portions of north-central into northeast LA, near and to the
north of Monroe. The 18z SHV indicated the presence of a cap in the
1-2-km layer and it`s likely the storms are elevated above that
feature. The downstream air mass across northeast LA into
west-central MS continues to destabilize as temperatures have warmed
into the mid 80s with lower 70s dewpoints. And, some recent model
guidance suggests that the current storm activity will become
progressively more surface based as it moves into MS.

The wind profile observed in the SHV sounding data is considerably
stronger than that currently being observed by the current KDGX VWP.
As such, the potential exists for organized storm modes, including
supercells and bow echoes capable of large hail and damaging winds
as the primary hazards. However, a few tornadoes cannot be ruled
out, especially as the stronger low-level wind field (ref. 18z SHV
sounding) overspreads the area.
