Mesoscale Discussion 0052
NWS Storm Prediction Center Norman OK
1146 AM CST Mon Jan 13 2020
Areas affected...eastern North Carolina and a small part of
northeastern South Carolina
Concerning...Severe potential...Watch unlikely
Valid 131746Z - 131945Z
Probability of Watch Issuance...20 percent
SUMMARY...Convection approaching Fayetteville, NC has some
organization and may pose a risk of wind gusts approaching severe
levels through the discussion area. A WW issuance is not
anticipated for this threat, though convective trends are being
monitored.
DISCUSSION...Convection across western and southern portions of the
discussion has exhibited an uptick in the recent hour based on radar
and lightning imagery. A complex near Scotland/Hoke counties in
southern North Carolina has exhibited some organization and a bowing
segment. Convection in Horry County, South Carolina has exhibited
some rotation in the last half hour and an increase in lightning as
well. These storms are in a weakly unstable environment
characterized by 1000-1500 J/kg MUCAPE. Shear profiles are mostly
unidirectional but do increase in speed with height, with 35-40 kt
mid-level flow supporting the observed organization with cells
across the discussion area. Slightly more low-level backing in
surface winds across southern North Carolina may be supporting
updraft rotation noted in that area. Though the overall severe risk
with this activity should be isolated over the course of the
afternoon, an isolated damaging wind gust or two cannot be
completely ruled out. Convective trends are being monitored, but
the issuance of a WW is not anticipated at this time.
