An anomalously hot and humid air mass was in place ahead of a cold front. Widespread showers and storms developed ahead of this front in a highly unstable environment with sufficient deep layer shear to lead to more organized multicell clusters. This led to scattered wind damage reports. In addition, with high PWATs, flash flooding developed in downtown Columbia.
