   Concerning...Tornado Watch 214...

   Valid 120607Z - 120800Z

   The severe weather threat for Tornado Watch 214 continues.

   SUMMARY...An isolated severe threat should continue for a couple
   more hours across parts of southeastern Oklahoma.

   DISCUSSION...A small convective cluster is ongoing across parts of
   southeastern OK early this morning. This cluster is being aided by a
   30-35 kt southerly low-level jet. Some evidence of a rear-inflow jet
   can be seen from the velocity data from KTLX/KSRX. Indeed, a recent
   measured gust to 55 kt was recorded at KMLC (McAlester OK). With a
   moderately unstable airmass is place downstream and sufficient shear
   to support updraft organization, this should support an isolated
   threat for mainly severe/damaging winds as thunderstorms spread
   slowly eastward over the next couple of hours. With sufficient
   low-level shear also in place, an embedded tornado may also occur.
   While small extensions in area for Tornado Watch 214 are possible,
   additional watch issuance is not anticipated.
