   Mesoscale Discussion 0830
   NWS Storm Prediction Center Norman OK
   0110 PM CDT Wed May 24 2017

   Areas affected...Much of southern GA...far northern FL into far
   southern SC

   Concerning...Tornado Watch 263...

   Valid 241810Z - 241945Z

   The severe weather threat for Tornado Watch 263 continues.

   SUMMARY...Overall threat across much of southern GA into far
   northern FL and far southern SC appears to be diminishing as earlier
   convection has largely stabilized the boundary layer. However, a
   severe threat, along with the risk for a few tornadoes, will
   continue across central SC. Portions of WW 263 may be canceled early
   if convective trends continue to decline.

   DISCUSSION...The tornado threat appears to be quickly diminishing
   across much of Tornado Watch 263. Deep-layer flow has veered across
   much of southwest GA as earlier vort max continues to lift northward
   away from the region and a dryslot begins to shift east from AL.
   Additionally, earlier convection that moved across northern FL and
   is now over coastal southeast GA into far southern SC has largely
   stabilized southern portions of the watch area. Some severe threat,
   including potential tornadoes, is still possible across northern
   portions of the watch area across central South Carolina where
   stronger instability exists and low level flow is still backed from
   the southeast. Depending on convective trends, portions of WW 263
   may be canceled early by local WFOs.
