   Mesoscale Discussion 0887
   NWS Storm Prediction Center Norman OK
   1016 PM CDT Sat May 27 2017

   Areas affected...Upstate SC...Northeast GA

   Concerning...Severe potential...Watch possible 

   Valid 280316Z - 280445Z

   Probability of Watch Issuance...40 percent

   SUMMARY...The damaging wind threat will increase later tonight ahead
   of a bowing thunderstorm line currently over eastern TN. Downstream
   watch issuance is possible.

   DISCUSSION...At 03Z, a well-defined QLCS is ongoing across eastern
   TN, with the Knoxville ASOS recently reporting a 49 kt wind gust.
   There remains some uncertainty as to the intensity of this system as
   it crosses the Appalachians, but given its well-organized appearance
   and the presence of sufficient buoyancy and shear downstream, some
   damaging wind threat is likely to persist into the overnight hours.
   Downstream watch issuance into portions of northeast GA and upstate
   SC is possible if it appears that sufficient intensity will be
   maintained into those areas.
