Mesoscale Discussion 1361
NWS Storm Prediction Center Norman OK
1118 PM CDT Wed Jun 18 2025

Areas affected...portions of eastern Arkansas into western
Tennessee...far southwestern Kentucky...and far northern Mississippi

Concerning...Severe potential...Watch unlikely=20

Valid 190418Z - 190545Z

Probability of Watch Issuance...5 percent

SUMMARY...An instance or two of marginally severe hail is possible.
A WW issuance is not expected.

DISCUSSION...Multiple multicellular clusters have fluctuated in
intensity over the past couple of hours, with MRMS MESH data
suggesting that isolated instances of marginally severe hail may be
occurring. These storms are developing ahead of an approaching 500
mb impulse, where residual buoyancy (1000-2000 J/kg MLCAPE)
coinciding with 35 kts of effective bulk shear (04Z mesoanalysis),
may support a couple instances of marginally severe hail over the
next couple of hours. Even so, the severe threat should be isolated
enough to preclude a WW issuance.
