   0536 PM CST Sat Jan 11 2020

   Areas affected...portions of central and northeast GA into upstate
   SC...western NC...northeast TN...western VA and southern WV

   Concerning...Tornado Watch 15...17...

   Valid 112336Z - 120100Z

   The severe weather threat for Tornado Watch 15, 17 continues.

   SUMMARY...Damaging wind gusts and a tornado or two remain possible
   across WW 15 and 17. An isolated severe threat may extend north of
   WW 17 into parts of western VA and southern WV.

   DISCUSSION...The QLCS currently extending from far northeast
   TN/western NC south/southwest across central GA continues to produce
   near-severe measured gusts generally ranging from around 40 kt to 55
   kt. Additionally, a few embedded supercells and/or mesovortex
   circulations have been noted over the last hour. As the line
   continues east/northeast around 40-50 kt, damaging wind gusts will
   remain possible across the remainder of WW 15 and 17, given intense
   low level winds and MLCAPE as high as 500 J/kg extending across much
   of GA into SC.

   At least a few hundred J/kg MLCAPE extends further north into
   western NC/VA. Given the strength of low level flow and stronger
   forcing lifting northeast toward the central Appalachians, a few
   severe gusts could persist north of ww 17 into parts of western
   VA/southern WV. Trends will be monitored across this area for
   possible watch issuance.
