MD 0664 CONCERNING SEVERE POTENTIAL…TORNADO WATCH LIKELY FOR NORTHEAST OK INTO SOUTHEAST KS AND EXTREME SOUTHWEST MO
Mesoscale Discussion 0664
NWS Storm Prediction Center Norman OK
0800 PM CDT Mon May 06 2024
Areas affected…Northeast OK into southeast KS and extreme
southwest MO
Concerning…Severe potential…Tornado Watch likely
Valid 070100Z – 070230Z
Probability of Watch Issuance…95 percent
SUMMARY…The tornado threat will increase through the evening.
Local extension of WW 189 may be needed, with Tornado Watch issuance
eventually expected downstream.
DISCUSSION…Convective showers are beginning to increase from
central/northeast OK into southeast KS, ahead of the primary
corridor of supercells to the southwest. With a continued increase
of the low-level jet expected into the evening, there will be some
potential for these showers to deepen into mature supercells with
time, within a very favorable environment characterized by MLCAPE in
excess of 2000 J/kg and strong low-level and deep-layer shear.
Should this occur, some increase in tornado potential will be
possible through mid evening, with an increase in storm coverage
later tonight as ongoing supercells across OK and far southern KS
spread east-northeastward.
Local extension of WW 189 may be needed across parts of northeast
OK/southeast KS in the short term. New Tornado Watch issuance will
eventually be needed farther northeast, extending into southwest MO.
Timing of the new watch will be dependent on the evolution of
developing cells ahead of the main cluster of convection to the
west.
