Mesoscale Discussion 0443 NWS Storm Prediction Center Norman OK 0102 PM CDT Wed Apr 05 2017 Areas affected...Coastal SC/NC Concerning...Severe potential...Watch likely Valid 051802Z - 051900Z Probability of Watch Issuance...80 percent SUMMARY...Tornado watch will likely be issued by 19z across portions of coastal SC and NC. DISCUSSION...Air mass is recovering across the coastal plain of SC into coastal NC as temperatures rise through the 70s just inland from the sea breeze. There is increasing concern that upstream supercell activity over CAE CWA will spread east into ILM CWA just south of synoptic front draped from Darlington county to Pender county. It's not entirely clear how far inland the sea breeze will advance but a narrow wedge of instability should prove receptive for upstream activity to advance east with an attendant tornado, hail/wind threat. ..Darrow/Hart.. 04/05/2017 ...Please see www.spc.noaa.gov for graphic product...
