Seems like SPC has dropped the idea of strong tornadoes.
The severe weather threat for Tornado Watch 13, 15, 16 continues.
SUMMARY...Threat for damaging wind gusts and perhaps a brief tornado
will continue across central/east-central MS and west-central AL for
the next few hours.
DISCUSSION...Regional radar imagery reveals two somewhat more
organized storm clusters, one moving through Calhoun county MS and
the other in Holmes and Carroll counties in central MS. Downstream
air mass, particularly immediately downstream of the Holmes/Carroll
cluster, appears favorable for storm persistence and perhaps
strengthening. In this area, a corridor of slightly higher dewpoints
(i.e. around 64 deg F) exists amidst moderate southerly surface
winds and strong vertical shear. Storm motion of both of these
storms is northeasterly at 45 kt, taking them to the MS/AL border
around 00Z. A extension in time will be needed for a few southern
counties Tornado Watch 13 given its current expiration time of 23Z.
