   Areas affected...western Oklahoma

   Concerning...Severe potential...Tornado Watch likely 

   Valid 072224Z - 072330Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Western Oklahoma is being monitored for thunderstorm
   initiation. Supercells capable of tornadoes and large hail will be
   the initial primary threats. A tornado watch will likely be needed
   soon.

   DISCUSSION...Early this evening, visible imagery shows a band of
   deepening cumulus along what appears to be a confluence boundary.
   With temperatures in the upper 70s to near 80, the surface layer is
   only weakly capped, and discrete storms will probably develop soon
   within the moderately unstable warm sector. VWP data show only
   modest vertical wind profiles, but both deep shear and size of
   low-level hodographs will increase during the early evening as the
   low-level jet strengthens in advance of an approaching mid-level
   jet.
