   Mesoscale Discussion 0002
   NWS Storm Prediction Center Norman OK
   1009 AM CST Wed Jan 03 2018

   Areas affected...Coastal Carolina

   Concerning...Freezing rain 

   Valid 031609Z - 032015Z

   SUMMARY...Freezing rain will spread/develop northeast along the
   South Carolina coast into southern North Carolina into the early
   afternoon.  Freezing rain rates on the order of .10" per hour will
   be common.

   DISCUSSION...Surface low is beginning to deepen off the FL coast and
   will lift north-northeast during the day in response to strong
   mid-level short-wave trough. Precip shield is expanding ahead of
   this feature across southeast GA and southern SC within intensifying
   warm advection corridor. Current surface observations support the
   strengthening warm advection and freezing rain is the predominant
   precip type along the immediate SC coast. 12z sounding from CHS
   exhibits a significant warm layer between 950mb-800mb and the latest
   3km NAM guidance suggests further warming is possible around 900mb
   through 16z-17z at CHS before the column cools enough for a
   transition to ice pellets and snow later this afternoon. While ice
   pellets and snow will be noted a few counties inland, it appears the
   heaviest precipitation over the next 2-4hr will be near the coast
   and primarily freezing rain.
