MD 0149 CONCERNING TORNADO WATCH 26… FOR CENTRAL NORTH CAROLINA AND EASTERN SOUTH CAROLINA.

Mesoscale Discussion 0149
NWS Storm Prediction Center Norman OK
0935 AM CST Wed Mar 05 2025

Areas affected...Central North Carolina and eastern South Carolina.

Concerning...Tornado Watch 26...

Valid 051535Z - 051700Z

The severe weather threat for Tornado Watch 26 continues.

SUMMARY...Wind damage/tornado threat to increase by mid-day.

DISCUSSION...A convective line has produced consistent wind damage
this morning with a 52 knot gust at 1512Z at KBUY. This wind threat
will continue and likely increase as the environment downstream
destabilizes. In addition, low-level moisture advection and some
heating through broken cloud cover should lead to 500 to 1000 J/kg
MLCAPE by early afternoon across parts of eastern South Carolina and
eastern North Carolina. Given 450+ m2/s2 0-1km SRH and 75 knots at
1.5 km from the KRAX VWP, the embedded QLCS tornado threat and
severe wind threat will likely increase as the line interacts with
greater instability. In addition, a few embedded supercells may be
possible where instability is greatest which could lead to regions
of locally higher threat within the line. 

Expect an increase in organization and intensity of the squall line
(first indicated by the presence of lightning) within the next 1 to
2 hours with the threat persisting through the afternoon/evening. An
additional tornado watch will eventually be needed downstream of
watch 26 across parts of eastern North Carolina and southeast
Virginia.
