Mesoscale Discussion 1294
NWS Storm Prediction Center Norman OK
0232 PM CDT Thu Jul 15 2021
Areas affected...Northeast OK...Southeast KS...Southwest MO
Concerning...Severe potential...Watch unlikely
Valid 151932Z - 152130Z
Probability of Watch Issuance...20 percent
SUMMARY...A few strong storms are possible later this afternoon,
with a threat of locally damaging winds.
DISCUSSION...At 1930Z, convection is gradually increasing near a
weak surface boundary across southeast KS into southwest MO, in
advance of an MCV moving across south-central KS. While widespread
clouds are noted across much of the area, somewhat more substantial
heating has occurred to the south/east of the boundary, where some
clearing has occurred this afternoon. Where temperatures have risen
into the mid/upper 80s F, MLCAPE has increased into the 1500-2500
J/kg range, per recent mesoanalyses. A few strong storms may evolve
along this instability axis this afternoon, as modestly enhanced
midlevel flow associated with the MCV overspreads the region. A few
briefly organized cells/clusters will be possible, with locally
damaging winds possible where low-level lapse rates have steepened.
Another round of potentially strong storms will be possible this
evening across the same general region, as a low-level jet becomes
focused into the area.
