   Areas affected...western and central Arkansas

   Concerning...Tornado Watch 562...

   Valid 050143Z - 050245Z

   The severe weather threat for Tornado Watch 562 continues.

   SUMMARY...Tornado risk continues across western/central Arkansas.
   Damaging wind risk increasing as storm mode becomes linear.

   DISCUSSION...Surface objective analysis shows a nose of increasing
   MLCAPE values around 500-1000 J/kg moving into central Arkansas. The
   VAD profile from Little Rock shows backed surface winds with a
   curved hodograph, which will further support downstream tornado
   threat over the next couple of hours. In the last hour, storm mode
   has transitioned to become more linear with embedded mesovorticies
   developing within the line of storms. Strong winds (around 60-65
   kts) are being sampled just above ground from the Ft Smith radar
   indicative of the increasing low level jet axis extending across
   western Arkansas. The VAD profile from Ft. Smith shows the hodograph
   has become elongated/linear supporting a more linear storm mode.
   Damaging wind potential will increase across central Arkansas as
   this line advances east. Embedded QLCS tornadoes will continue to be
   possible.
