Areas affected...parts of eastern Texas into southwestern Arkansas
and northwestern Louisiana

Concerning...Severe Thunderstorm Watch 16...

Valid 111240Z - 111515Z

The severe weather threat for Severe Thunderstorm Watch 16
continues.

SUMMARY...Isolated strong to severe thunderstorm development may
continue through 9-11 AM CST, with hail remaining the primary
potential severe hazard.

DISCUSSION...An initial area of stronger large-scale ascent appears
to be pivoting north of the Red River Valley.  However, one
persistent strong cell/small cluster of convective development
continues to be supported by a focused area of enhanced
lower/mid-tropospheric warm advection now spreading across the
Tyler, TX toward Shreveport, LA vicinities.  Based on latest model
output, it remains unclear how much longer this will be maintained,
but sustained weakening trends have yet to develop, and it is on
track to reach the Shreveport vicinity by 15Z.

Otherwise, into the 15-17Z time frame, weaker low-level warm
advection appears likely to persist within a corridor north of the
upper Texas coastal plain through the Shreveport vicinity, beneath
at least weakly difluent high-level low.  This may support
continuing convective development, with the stronger thunderstorm
development perhaps shifting closer to the surface frontal zone,
near the Huntsville vicinity.
