   SUMMARY...A wintry mix of sleet and freezing rain is expected to   
   slowly spread north and east over the next 3-5 hours across portions   
   of the southern Appalachians. Areas currently observing snow will   
   likely see a transition to sleet/freezing rain during this period.   
   Freezing rain rates of 0.05 to 0.1 inch/hour appear possible.   
      
   DISCUSSION...Recent RAP/HRRR solutions appear to be capturing   
   ongoing precipitation-type trends well per latest ASOS/AWOS   
   observations and mPING reports. Surface observations also depict a   
   trough axis extending from southwest AL into the southern   
   Appalachians where surface pressure falls on the order of   
   approximately 1 mb/hour have been noted since 18 UTC. As broad-scale   
   ascent continues to increase with the gradual approach of the upper   
   wave to the west, further intensification of the surface trough   
   across the Southeast and lee of the southern Appalachians is   
   expected with a slight augmentation of southerly low-level winds and   
   warm air advection. This will shift the low-level freezing line   
   northward over the next several hours, resulting in a transition   
   from predominantly snow to a mixture of freezing rain and sleet (and   
   potentially to rain if surface temperatures can sufficiently warm).   
   Additionally, as low-level ascent spreads east/northeast, freezing   
   rain/sleet should become more widespread across portions of the   
   western Carolinas and into parts of VA - especially as low-level   
   saturation is achieved later this evening. Latest forecast guidance   
   continues to suggest that freezing rain rates upwards of 0.05 to 0.1   
   inch/hour will be possible.
