Mesoscale Discussion 0919
NWS Storm Prediction Center Norman OK
0230 PM CDT Sun May 31 2026
Areas affected...Southeast MO...far southern IL...far western
KY...and far northwest TN
Concerning...Severe potential...Watch unlikely
Valid 311930Z - 312130Z
Probability of Watch Issuance...20 percent
SUMMARY...Locally damaging gusts will be possible with a cluster of
thunderstorms tracking southeastward.
DISCUSSION...A loosely organized cluster of thunderstorms is
tracking southeastward across southeastern MO, which has produced a
few damaging gusts and small hail. Despite limited deep-layer shear
(around 25-kt midlevel flow per regional VWP), warm/moist inflow and
steepened lapse rates (around 2000 J/kg MLCAPE) will continue to
maintain this activity as it continues southeastward along the CAPE
gradient over the next couple hours. Locally damaging gusts will
remain possible, but current thinking is that the overall severe
risk will remain too limited for a watch.
