   Mesoscale Discussion 0162
   NWS Storm Prediction Center Norman OK
   0316 PM CDT Tue Mar 20 2018

   Areas affected...Northern/Central FL

   Concerning...Tornado Watch 17...

   Valid 202016Z - 202145Z

   The severe weather threat for Tornado Watch 17 continues.

   SUMMARY...Tornado threat is shifting into the eastern/southern
   portions of ww17.

   DISCUSSION...Westerly flow is strengthening across the FL Peninsula
   this afternoon as a strong short-wave trough progresses across AL
   toward GA. As a result, deeper convergence/forcing is beginning to
   focus off the SC coast with weaker convergence arcing across the
   central peninsula. Over the next few hours it appears the greater
   supercell threat will shift toward the central FL Atlantic coast and
   trailing convection may become more linear in nature. For these
   reasons it appears the overall tornado threat may be decreasing, but
   large hail and locally damaging winds remain possible.

   With time, strong convection should sag south of ww17 but this
   activity is expected to pose primarily an isolated wind/hail threat.
