   Mesoscale Discussion 0023
   NWS Storm Prediction Center Norman OK
   1040 PM CST Fri Jan 10 2020

   Areas affected...southeast Missouri/Arkansas/northeast
   Texas/northwest Louisiana

   Concerning...Tornado Watch 5...

   Valid 110440Z - 110645Z

   The severe weather threat for Tornado Watch 5 continues.

   SUMMARY...Severe risk continues -- along with potential for a couple
   of brief tornadoes.

   DISCUSSION...Radar loop depicts a solid line of convection moving
   eastward across WW 005, with embedded LEWPs/bows/rotating updrafts. 
   The overall kinematic environment remains quite favorable for
   continued severe risk.  As such, with sufficient instability within
   the warm sector -- particularly with southward extent across
   Arkansas and into the Arklatex -- severe risk will likely continue
   over the next few hours.  

   While much of the convection remains well-contained within the
   watch, a bowing segment of the line near the Arkansas/Missouri
   border moving east-northeast at 45 kt continues to rapidly approach
   the northeast corner of the watch.  Though the thermodynamic
   environment is much less favorable than areas farther south, some
   risk for a continuation of isolated wind risk into the Mid
   Mississippi Valley warrants at least some consideration for
   downstream WW issuance.
