Mesoscale Discussion 0771

0241 PM CDT Sun May 15 2022

Areas affected...Much of AR

Concerning...Severe Thunderstorm Watch 217...218...

Valid 151941Z - 152115Z

The severe weather threat for Severe Thunderstorm Watch 217, 218
continues.

SUMMARY...Threat for hail and/or damaging wind gusts will continue
across AR. Trends are being monitored for possible downstream watch
issuance.

DISCUSSION...A large cluster of thunderstorms persists across
northern AR. Southwestern portion of this cluster continues to move
southward, although some western co*ponent has been noted in recent
trends. Air mass in the vicinity and downstream of this portion of
the cluster is very unstable, with mesoanalysis estimating MLCAPE
over 3000 J/kg. SRX VAD shows a weakly sheared air mass, with storm
motion dominant by forward-propagation. Expectation is for this
cluster to continue southward/south-southwestward for the next few
hours, with a continued risk for hail and/or damaging wind gusts.
Trends with storm motion will be monitored closely and a downstream
watch maybe needed across west-central/southern AR if trends merit.
