   Areas affected...northern Georgia...southeast Tennessee...western
   and central portions of North and South Carolina

   Concerning...Tornado Watch 113...

   Valid 130317Z - 130445Z

   The severe weather threat for Tornado Watch 113 continues.

   SUMMARY...Severe/tornado risk continues across WW 112 and 113.

   DISCUSSION...While earlier, more cellular convection has
   weakened/moved out of WW 112/113, an organized band of storms --
   with embedded rotational radar signatures -- moving across northern
   Alabama will continue shifting east into northwest Georgia/southeast
   Tennessee over the next hour.  Some low-level moistening has
   occurred across the area on strong southerly surface flow, with
   upper 60s dewpoints now extending to the GA/TN border, which has
   boosted mixed-layer cape to near 1000 J/kg per RUC-based objective
   analysis.  

   The latest KFFC WSR-88D VWP shows extreme low-level and deep-layer
   shear (53 kt sfc-1 km and 86 kt 0-6 km), and therefore -- in
   conjunction with increased buoyancy -- expect risk for tornadoes and
   locally damaging winds to continue.

   Meanwhile east of the existing watches, into the western Carolinas,
   similarly strong low-level and deep-layer shear is indicated.  While
   instability is weaker, a gradual increase in CAPE with time appears
   to be fueling small cellular development.  With this convection
   possibly increasing in coverage/intensity with time, a new tornado
   watch may become necessary.
