   Areas affected...eastern OK

   Concerning...Tornado Watch 696...

   Valid 310131Z - 310230Z

   The severe weather threat for Tornado Watch 696 continues.

   SUMMARY...A sustained supercell or two is possible as storms over
   southeast Oklahoma potentially deepen while moving north-northeast.
   An extension of WW 696 or a new WW may be needed.

   DISCUSSION...Deepening warm-sector convection has increased across
   southeast OK into far north TX. Environment here is conditionally
   favorable for sustained supercell development with mid to upper 60s
   surface dew points and effective SRH around 250-350 m2/s2. Both HRRR
   and WoFS runs have largely been devoid of development here, but the
   RRFS has suggested some potential for a supercell or two to become
   sustained as activity moves north-northeast across eastern OK. With
   low-level forcing for ascent stronger to the north and west, it is
   uncertain whether these cells will truly deepen and sustain
   supercell structures.
