Mesoscale Discussion 1261
NWS Storm Prediction Center Norman OK
0450 PM CDT Mon Jun 22 2026
Areas affected...Central North Carolina into Southern Virginia
Concerning...Severe potential...Watch possible
Valid 222150Z - 222345Z
Probability of Watch Issuance...60 percent
SUMMARY...A loosely organized line of thunderstorms is moving
eastward into portions of central North Carolina/southern Virginia.
Damaging straight-line winds -- especially along any bowing segments
or with interacting outflows -- will be possible through this
evening.
DISCUSSION...A loosely organized line of thunderstorms in western
North Carolina and portions of southwestern Virginia will continue
to move east through the late afternoon and into the early evening.
Strong daytime heating has resulted in surface temperatures reaching
the low-to-mid 90s F, and proximity RAP soundings show a deep and
well-mixed boundary layer with LCLs exceeding 1800 meters. As a
result, DCAPE values exceed 1200 J/kg ahead of these storms and
should support strong downdrafts. Though current VAD wind profiles
from Roanoke and Wakefield show small, disorganized hodographs,
mesoanalysis shows around 30 kts of effective layer shear that will
support continued loose organization with eastward extent. Given the
30 kts of deep-layer shear and strong DCAPE, sustained and strong
downdrafts could produce 55-70 MPH winds through the early evening.
A severe thunderstorm watch is being considered to cover this
threat.
