MD 0771 CONCERNING TORNADO WATCH 214… FOR PORTIONS OF SOUTHEASTERN OK
Mesoscale Discussion 0771
NWS Storm Prediction Center Norman OK
0107 AM CDT Fri May 12 2023
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.
