Slow-moving Frontal System Triggers Storms, Flooding Across Ohio Valley

A slow-moving frontal boundary draped across the central US from the Central Plains across the Middle Mississippi and Ohio Valleys and into the Mid-Atlantic region has been providing the focus for numerous showers and thunderstorms the past few days while an associated East-West oriented, upper-level jet stream located near the front has helped to organize and strengthen the storms.
