[html]MD 0743 CONCERNING SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY FOR THE WESTERN CAROLINAS AND SOUTHERN VIRGINIA.
Mesoscale Discussion 0743
NWS Storm Prediction Center Norman OK
0137 PM CDT Thu May 08 2025
Areas affected...The western Carolinas and southern Virginia.
Concerning...Severe potential...Severe Thunderstorm Watch likely
Valid 081837Z - 082000Z
Probability of Watch Issuance...80 percent
SUMMARY...Storms developing over the mountains will eventually
beco*e severe with a threat for large hail and damaging wind gusts.
DISCUSSION...Visible satellite shows some deeper convection
developing along/near the crest of the Appalachians. As low-level
moisture continues to advect north and the boundary layer heats up,
instability will increase. This should permit storms to strengthen
further and move off of the terrain. Effective shear around 40 knots
(per SPC mesoanalysis) and 1500 J/kg MLCAPE will support the
potential for organized storms, including supercells. Expect a more
discrete mode with a hail threat initially before storms likely
congeal into one or more clusters with an increasing damaging wind
threat late this afternoon and into the evening.
A severe thunderstorm watch will likely be needed by mid-afternoon
to address this evolving threat.
