   Areas affected...Northeast Arkansas into the Missouri Bootheel

   Concerning...Tornado Watch 32...36...

   Valid 150320Z - 150515Z

   The severe weather threat for Tornado Watch 32, 36 continues.

   SUMMARY...Supercells with a history of producing tornadoes will
   continue to pose a tornado threat (including significant tornadoes)
   for the next couple of hours as they move into northeast Arkansas
   and southeast Missouri.

   DISCUSSION...Two long-lived supercells moving across north-central
   AR and south-central MO have had a history of producing tornadoes
   per dual-pol data and spotter reports. Based on rotational velocity
   estimates and the magnitude of the convective environment
   (characterized by STP values up to 10), one or more of these
   tornadoes were likely significant (EF-2+). These cells will continue
   to reside in this exceptionally rare STP environment for the next
   1-2 hours as they move into far northeast AR and southeast MO.
   Consequently, the potential for additional long-track and
   significant (possibly intense) tornadoes will continue across this
   region.
