Mesoscale Discussion 1318
NWS Storm Prediction Center Norman OK
0505 PM CDT Thu Jun 25 2026
Areas affected...Northeastern Oklahoma into northwestern Arkansas
Concerning...Severe potential...Watch possible
Valid 252205Z - 252330Z
Probability of Watch Issuance...40 percent
SUMMARY...The potential for a few strong to severe gusts and hail
will continue spreading east-southeastward in the near term.
DISCUSSION...Aided by a remnant MCV and midlevel trough moving
across eastern KS, a long-lived cluster of thunderstorms is tracking
east-southeastward across northeastern OK this afternoon. Given the
well-established cold pool, around 35 kt of 0-6 km shear (per INX
VWP), and a warm/moist PBL immediately downstream, strong to severe
wind gusts and sporadic severe hail will remain possible in the near
term. However, as the cluster of storms becomes increasingly
displaced from the MCV/midlevel trough and related enhancement to
the deep-layer shear (much weaker flow from SRX VWP), a gradual
weakening trend is expected over the next few hours. Therefore, a
downstream watch is not currently expected, though convective trends
are being monitored.
