Mesoscale Discussion 1928
NWS Storm Prediction Center Norman OK
1123 PM CDT Fri Aug 16 2024

Areas affected...portions of extreme eastern Oklahoma into central
Arkansas

Concerning...Severe Thunderstorm Watch 629...

Valid 170423Z - 170600Z

The severe weather threat for Severe Thunderstorm Watch 629
continues.

SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 629. Damaging gusts remain the main threat with these storms
over the next few hours.

DISCUSSION...An MCS has materialized from congealing storms over the
last few hours, with strong wind gusts over 50 mph recently
reported. Preceding the eastern portion of the MCS is a cooler
airmass, characterized by surface temperatures in the upper 70s to
low 80s F. However, along the western periphery of the MCS track are
warmer surface temperatures between 85-90 F, which also reside
beneath the eastern periphery of a modest LLJ and acco*panying WAA.
As such, the portion of the MCS cold pool propagating into this
airmass has the greatest chance for supporting stronger updrafts and
corresponding downdrafts, which may penetrate the increasing MLCINH.
Here, a few additional strong to severe gusts may occur over the
next few hours.
