   Concerning...Tornado Watch 44...

   Valid 151425Z - 151600Z

   The severe weather threat for Tornado Watch 44 continues.

   SUMMARY...The severe weather threat will increase through the
   morning across tornado watch 44.

   DISCUSSION...Widespread thunderstorm activity has formed along the
   cold front from northern Louisiana to western Tennessee. The
   widespread nature of this convection has resulted in a messy storm
   mode. However, any additional storms which develop on the warm side
   of the boundary will pose a threat for all severe hazards including
   large hail, severe wind gusts, and tornadoes. This baroclinic zone
   will likely persist for much of the day with the greatest tornado
   threat persisting slightly southeast of this zone. More organized
   supercells are present across northern Louisiana where storm mode
   has remained more discrete. These supercells, and additional
   development south and east of these storms may be the beginnings of
   long-track supercells which will persist for much of the daytime
   period with a threat for large hail (some 2+ inches), severe wind
   gusts, and strong to intense tornadoes.
