MD 1338 CONCERNING TORNADO WATCH 429... FOR PARTS OF THE EASTERN OK/TX PANHANDLES INTO FAR NORTHWEST OK



Mesoscale Discussion 1338
NWS Storm Prediction Center Norman OK
0605 PM CDT Tue Jun 17 2025

Areas affected...Parts of the eastern OK/TX Panhandles into far
northwest OK

Concerning...Tornado Watch 429...

Valid 172305Z - 180000Z

The severe weather threat for Tornado Watch 429 continues.

SUMMARY...Intensification of an ongoing discrete supercell is
possible as it continues southeastward over the next couple hours --
with an associated risk of supercell tornadoes.

DISCUSSION...A discrete supercell has developed over the OK
Panhandle, within a localized zone of surface convergence. Strongly
unstable inflow for this storm and large streamwise vorticity
(250-300 m2/s2 effective SRH) will support the intensification of
this storm as it tracks southeastward over the next couple hours. If
this occurs, supercell tornadoes and large hail will both be
concerns.
