MD 0274 CONCERNING TORNADO WATCH 53...54... FOR CENTRAL VA...CENTRAL/SOUTHEAST NC...NORTHEAST SC
Mesoscale Discussion 0274 NWS Storm Prediction Center Norman OK 0731 PM CDT Sun Apr 15 2018 Areas affected...Central VA...Central/Southeast NC...Northeast SC Concerning...Tornado Watch 53...54... Valid 160031Z - 160200Z The severe weather threat for Tornado Watch 53, 54 continues. SUMMARY...Tornado threat continues across Tornado Watches 53 and 54. DISCUSSION...Organized convective line continues to progress eastward into central VA, central NC, and northeast SC. Strong low-level flow exists ahead of the line. Regional VAD profiles have recently sampled 0-1 km bulk shear around 40 to 50 kt and 0-1 km SRH from 300 to 500 m2 per s2. This type of kinematic environment remains supportive of embedded QLCS tornadoes as well as damaging wind gusts. Thermodynamic environment is a little less favorable but enough instability (i.e. MLCAPE greater than 500 J/kg per the latest mesoanalysis) exist to support continued progression of the convective line. The northern extent of the severe threat is constrained by the wedge front draped from eastern WV across north-central VA and into the southern Delmarva Peninsula. The southern extent of the threat extends to the northeast SC/southeast NC coast. ..Mosier.. 04/16/2018 ...Please see www.spc.noaa.gov for graphic product...
