Strong storms fired over and near Iowa on Tuesday evening. The featured lapse is of GOES-16 imagery courtesy of the College of Dupage between about 4 and 11 PM. The imagery shows "long wave" radiance with brighter colors indicating colder temperatures. These cold temperatures are associated with the tops of vigorous updrafts that are associated with the strongest convection. The lapse shows a few storms firing over northern Iowa, before the cold front / dry line erupted. You can see an unzipping like motion as storms sequentially fire.
