In the wake of a morning mesoscale convective system (MCS) across Nebraska, storms refired during the evening hours across northwest Iowa within fairly weak deep-layer shear and up to 2000 J/kg MUCAPE. Storms produced locally damaging wind as cores collapsed, and training of storms resulted in locally heavy rainfall of 2 to 3 inches around the Iowa Great Lakes in the matter of an hour or two.
