Mesoscale Discussion 0973

0540 AM CDT Mon May 30 2022
Areas affected...Western IA...Far East-Central NE
Concerning...Severe Thunderstorm Watch 290...
Valid 301040Z - 301215Z
The severe weather threat for Severe Thunderstorm Watch 290
continues.
SUMMARY...There is a threat for isolated hail across western IA and
far east-central NE for the next few hours.
DISCUSSION...A north-south oriented band of thunderstorms recently
developed along the northern edge of the slightly better low to
mid-level moisture return. The steep mid-level lapse rates in place
support moderate buoyancy, evidenced by the presence of several
strong updrafts within the band. A southward-moving outflow boundary
may interact with this northward-moving band, leading to some
uncertainty regarding the overall duration and convective evolution
of these storms. Even so, given the moderate buoyancy and modest
deep-layer vertical shear, a few instances of severe hail are
possible within this band for the next hour or two.
