   Mesoscale Discussion 1177
   NWS Storm Prediction Center Norman OK
   0930 AM CDT Wed Jul 07 2021

   Areas affected...North FL Peninsula...southeast GA

   Concerning...Tornado Watch 341...

   Valid 071430Z - 071630Z

   The severe weather threat for Tornado Watch 341 continues.

   SUMMARY...The risk for a few tornadoes continues in association with
   Tropical Storm Elsa.

   DISCUSSION...At 1420z Tropical Storm Elsa was located just offshore
   of the FL coast northwest of Cedar Key.  A large area of rain
   east/northeast of the center covered much of north FL, however
   latest reflectivity data from KJAX shows a pronounced outer band
   lifting north/northwest just north of the GA/FL border with recent
   transient rotation, and more discrete cells/showers also over
   southeast GA producing occasional short-lived low-level rotation. 
   Modifying the latest KJAX VAD for observed storm motion from the
   southeast results in ESRH at or below 50 m2/s2, however latest RAP
   forecast soundings suggest increasing ESRH values over the next few
   hours as low-level winds increase as Elsa continues moving north. 
   Correspondingly, the risk for brief tornadoes may also increase over
   the next few hours.
