Mesoscale Discussion 0387
NWS Storm Prediction Center Norman OK
0108 PM CDT Fri Mar 31 2017
Areas affected...northern NC and southern VA
Concerning...Severe potential...Watch possible
Valid 311808Z - 311915Z
Probability of Watch Issuance...40 percent
SUMMARY...An isolated marginally severe hail and localized damaging
wind risk will probably develop.
DISCUSSION...Subjective surface analysis places a residual wedge
front/outflow boundary in a west-to-east orientation along the NC/VA
border. To the south of the boundary, temperatures have warmed into
the lower 70 degrees F with dewpoints in the lower 60s. As a
result, 0-3 km lapse rates are steepening and may aid in leading to
potential for localized damaging winds as storms develop and
intensify. Strong southwesterly low- to mid-level flow (40-55 kt at
500 mb) will serve to organize updrafts. Marginally severe hail and
gusty winds will be possible with the stronger cores as storms
develop eastward near/along the NC/VA border this afternoon.
