   Concerning...Severe Thunderstorm Watch 245...247...

   Valid 260400Z - 260500Z

   The severe weather threat for Severe Thunderstorm Watch 245, 247
   continues.

   SUMMARY...Severe gusts and mesovortices may continue to northeast in
   the vicinity of the I-40 and I-44 corridors during the next 1-2
   hours.  A local extension-in-area for severe thunderstorm watch 247
   may be needed in the short term.

   DISCUSSION...Radar imagery during the past 30 minutes has shown a
   couple of brief circulations embedded near the apex of a bowing
   segment across the greater OKC metro.  An outflow boundary
   intersection with the bow likely contributed to a tornadic
   circulation over Canadian County during the past hour.  KTLX VAD has
   strengthened during the past 2 hours with 0-1km shear approaching
   40kt.  Given the moist/unstable airmass in place with a mature
   small-scale bow echo, a continued risk for severe gusts/wind damage
   and perhaps brief mesovortices seems probable during the next 1-2
   hours.
