Mesoscale Discussion 1700
NWS Storm Prediction Center Norman OK
0106 PM CDT Wed Jul 24 2024
Areas affected...Central Illinois...Central Indiana...and
West-Central Ohio
Concerning...Severe potential...Watch unlikely
Valid 241806Z - 242000Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated threat for severe wind/hail with the strongest
cells, watch unlikely.
DISCUSSION...Regional radar shows a few remnant convective clusters
moving southeast in concert with an east-west oriented cold front
across the region. Ahead of this activity, surface heating has led
to destabilization within the warm sector, with MLCAPE approaching
1500 J/kg. Satellite/radar shows additional convective cells
beginning to develop, mostly along the front. This activity is
expected to continue developing over the next few hours with some
expansion in coverage. Higher values effective bulk shear generally
remain displaced to the north behind the front, and therefore given
the proximate weak shear environment, storms are anticipated to
remain generally disorganized and watch issuance appears unlikely.
That said, relatively strong low-level lapse rates (near 8.5 C/km)
may promote a few damaging wind gusts with the strongest cells,
along with some potential for severe hail.
