Mesoscale Discussion 0800
NWS Storm Prediction Center Norman OK
0524 PM CDT Wed Jun 03 2020
Areas affected...Indiana into southern Ohio and West Virginia
Concerning...Severe potential...Watch unlikely
Valid 032224Z - 040100Z
Probability of Watch Issuance...20 percent
SUMMARY...Storms are likely to persist along a stalled front, with
occasional marginally severe wind or hail. Coverage of severe is
unlikely to necessitate a watch.
DISCUSSION...A few strong storms have been noted along a lengthy,
weak front from east-central IL into northern WV, mostly parallel to
weak midlevel winds aloft. A warm, moist air mass beneath cool
temperatures aloft is however contributing to 1000-1500 J/kg MLCAPE,
with sufficient convergence along the front to sustain new updrafts
given zero CIN.
Slow moving, pulse to multicell storms should persist for a few more
hours, with outflows resulting in an eventual east/southeastward
propagation. Some of the stronger storms may produce marginally
severe wind or hail.
