   Areas affected...northwest AR into northeast TX

   Concerning...Tornado Watch 156...157...

   Valid 280911Z - 281015Z

   The severe weather threat for Tornado Watch 156, 157 continues.

   SUMMARY...Strong gusts remain possible across Tornado Watch 156 and
   157 in the short term. Overall tornado/severe risk is expected to
   gradually wane with time/eastward extent the next couple of hours.

   DISCUSSION...The intensity of the QLCS slowly progressing east from
   northwest AR into north TX early this morning has gradually
   decreased over the past hour, especially north of the Red River.
   While some strong gusts remain possible, tornado potential is
   expected to wane over the next 1-2 hours due to weakening
   instability and less favorable deep-layer shear. Furthermore, radar
   data suggests outflow may be advancing ahead of the convection at
   least along some segments of the QLCS. While some strong winds may
   persist in the short term, downstream watches are not expected.
