Mesoscale Discussion 1172
NWS Storm Prediction Center Norman OK
0209 PM CDT Fri Jul 10 2020
Areas affected...southeastern Oklahoma and western Arkansas
Concerning...Severe potential...Watch unlikely
Valid 101909Z - 102115Z
Probability of Watch Issuance...5 percent
SUMMARY...Loosely organized, pulse-type convection may pose an
isolated damaging wind risk this afternoon, although a WW issuance
is not anticipated.
DISCUSSION...Although earlier convection associated with a mature
MCS entering southeastern Oklahoma has weakened, newer updrafts
near/southwest of FSM have materialized over the past half hour to
hour. These storms are beginning to propagate into an environment
characterized by strong instability (2500+ J/kg MLCAPE), but very
weak shear (10-15 knots through the 0-6km AGL layer). This suggests
that any organization with newer development should be weak, though
an advancing remnant cold pool from earlier convection may aid in
focusing newer convective development into loosely organized
clusters/lines, promoting a few damaging wind gusts. The magnitude
of instability and mid-level lapse rates may promote small hail
also. A WW issuance is unlikely for this activity.
