Areas affected...Portions of southeastern OK

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.
