   Areas affected...the greater Arklatex region

   Concerning...Tornado Watch 191...

   Valid 162231Z - 162330Z

   The severe weather threat for Tornado Watch 191 continues.

   SUMMARY...A tornado threat will continue across the greater Arklatex
   region as storms continues to progress northward into southeast
   Oklahoma and southwest Arkansas.

   DISCUSSION...Several low-topped, semi-discrete supercells continue
   across the Arklatex region as a warm front lifts north into
   southeast Oklahoma and southwest AR. A few tornadoes have been
   reported from these supercells, and with 100-200 m2/s2 of effective
   SRH in place along and ahead of the warm front, the tornado threat
   will continue for the next 1-2 hours. A gradual increase in storm
   interactions across southeast OK, new, more discrete storm
   development further east towards southern AR, and an expected
   eastward shift in the low-level jet may lead to an eastward
   transition in the zone of greatest tornado threat through the
   evening hours.
