Mesoscale Discussion 1374
NWS Storm Prediction Center Norman OK
0215 PM CDT Sat Jul 01 2023
Areas affected...southeast MO into southern IL
Concerning...Severe Thunderstorm Watch 427...
Valid 011915Z - 012045Z
The severe weather threat for Severe Thunderstorm Watch 427
continues.
SUMMARY...Damaging wind potential may be increasing across parts of
southeast Missouri into southern Illinois over the next 1-2 hours.
DISCUSSION...A cluster of storms from Phelps to Oregon Counties in
southeast MO is showing signs of intensification and better
organization over the past 30 minutes or so. Radar velocity
signatures have increased and reports of wind damage and hail have
been noted with this activity. While some semi-discrete cells
continue, the cluster over Texas County has shown better
organization and an increase in forward propagation. Very steep
lapse rates and DCAPE values exceeding 1000 J/kg indicate potential
for strong downbursts. If continued organization into a bowing
cluster continues, an attendant increase in a swath of damaging
winds is expected downstream across parts of east-central/southeast
MO and southern IL.
