   The severe weather threat for Tornado Watch 213 continues.

   SUMMARY...The supercell tornado threat is increasing and likely
   peaking in the next one to two hours for parts of the southern OKC
   metro.

   DISCUSSION...After several storm mergers in Grady County, latest
   KTLX radar imagery shows a couple consolidating supercell structures
   with more-organized mesocyclones in Canadian and Grady Counties. The
   near-storm environment is becoming increasingly favorable for
   sustained supercells, with expanding clockwise-turning hodographs
   (around 150 m2/s2 0-1km SRH from KTLX VAD and increasing) and lower
   70s boundary-layer dewpoints. Given slightly larger supercell
   structures moving into this environment, the supercell tornado risk
   is increasing and likely peaking in the next hour or two.
