   Areas affected...South-central OK into north TX

   Concerning...Severe Thunderstorm Watch 293...

   Valid 220542Z - 220615Z

   The severe weather threat for Severe Thunderstorm Watch 293
   continues.

   SUMMARY...50-60 mph gusts should persist for another hour or two
   with a gradually decaying QLCS in south-central OK that should
   spread into a part of north TX. WW 293 was scheduled to expire at
   06Z and will be locally extended in time until 08Z with a
   replacement WW unlikely.

   DISCUSSION...Leading edge of a long-lived QLCS is approaching the
   Red River in south-central OK. While the overall radar reflectivity
   and velocity have trended down, strong to locally severe gusts
   persist along the apex of the line with a 52 kt gust measured at
   KLAW at 0511Z, as well as 58-60 mph gusts recently measured at the
   Walters and Washington mesonet sites. Substantial MLCIN sampled in
   00Z FWD suggest that significant reintensification of the QLCS is
   unlikely, especially given how far south the leading outflow has
   outpaced the reflectivity cores in western north TX. Still, with
   robust pressure rises within the cold pool, a localized severe risk
   will probably persist for another hour or two in far south-central
   OK and perhaps into part of north TX.
