   Areas affected...portions of extreme north Texas into southern
   Oklahoma

   Concerning...Tornado Watch 149...

   Valid 200201Z - 200330Z

   The severe weather threat for Tornado Watch 149 continues.

   SUMMARY...The tornado threat should continue with ongoing storms
   along the Red River into southern OK over the next few hours.

   DISCUSSION...Several strong to severe thunderstorms are growing
   upscale into an MCS along the Red River, and these storms are poised
   to advance east-northeast across southern OK over the next few
   hours. An embedded, sustained supercell has recently produced a
   tornado in Love County, OK, and tornado potential is expected to
   continue with this storm, even if it morphs into a bowing/LEWP
   structure. Regional VADs depict large, curved hodographs across
   central TX/OK, and adequate surface based buoyancy remains in place.
   Furthermore, the 01Z Warn-on-Forecast run depicts continued swaths
   of stronger 0-2 km updraft helicity, indicative of longer-term
   low-level rotation potential with the ongoing storms. Given the
   strong low-level shear in place, a strong tornado remains possible.
