   Areas affected...portions of central and northern South Carolina
   into central North Carolina

   Concerning...Freezing rain 

   Valid 102334Z - 110330Z

   SUMMARY...Heavier freezing rain rates will continue to spread into
   northern South Carolina into central North Carolina through the
   evening hours. .06 inch/3 hour rates are expected.

   DISCUSSION...Low-level warm-air advection continues to intensify
   across GA into SC ahead of an approaching mid-level trough. While a
   wintry mix is ongoing across central portions of NC into SC, the
   continued WAA in the 850-700 mb layer will encourage freezing rain
   to become the predominant mode of wintry precipitation into the
   evening hours, as evident via 22Z RAP forecast soundings and 23Z
   mesoanalysis. Surface observations depict an increase in freezing
   rain already underway across northern SC into central NC, with
   heavier ice accretion rates likely this evening. Furthermore,
   high-resolution model guidance also shows a high likelihood of .06
   in/3 h ice accretion rates, especially in the 00-06Z time frame.
