Mesoscale Discussion 2093

0501 PM CDT Wed Sep 17 2025
Areas affected...portions of southern into central Iowa
Concerning...Severe potential...Watch unlikely
Valid 172201Z - 172330Z
Probability of Watch Issuance...5 percent
SUMMARY...A couple of additional severe gusts are possible over the
next few hours.
DISCUSSION...An organized multicellular cluster has developed over
southern IA, with a recent history of producing at least one
measured severe gust. This cluster is showing slight bowing
tendencies as it progresses through an ambient environment
characterized by 1000-1500 J/kg MLCAPE. However, vertical wind shear
is weak, and buoyancy does decrease downstream, likely because of
preceding showers and thunderstorms. As such, the severe threat
should remain sparse and localized.
