MD 0032 CONCERNING TORNADO WATCH 5… FOR CENTRAL AND EASTERN SOUTH CAROLINA AND FAR SOUTHERN NORTH CAROLINA

Mesoscale Discussion 0032
NWS Storm Prediction Center Norman OK
1156 AM CST Tue Jan 09 2024

Areas affected…central and eastern South Carolina and far southern
North Carolina

Concerning…Tornado Watch 5…

Valid 091756Z – 091930Z

The severe weather threat for Tornado Watch 5 continues.

SUMMARY…A squall line capable of damaging wind gusts and isolated
tornadoes is expected to continue through the afternoon.

DISCUSSION…Ahead of a squall line in western South Carolina and
eastern Georgia, instability remains weak, but sufficient for some
damaging wind threat. Strong southeasterly 15-25 kt surface winds
continue to advect significant low-level moisture northward which
will further destabilize areas ahead of the line. Given the very
strong wind profile (80 knots at 1km per CAE VWP), this line will
likely continue to produce damaging winds, even with meager
instability. In addition, strong shear with clockwise curved
hodographs will support some QLCS tornado threat, particularly
across southern South Carolina where mid-60s dewpoints have advected
onshore.

Additionally, a confluence band of showers has started to develop
off the South Carolina coast. As cooler air aloft overspreads this
region and low-level moisture continues to advect northward,
instability is expected to increase and may lead to some potential
for strong supercells and perhaps a greater threat for strong
tornadoes given the greater instability and discrete mode.
