As those elevated storms approached the central third of Iowa, the linear storms began to backbuild and with increasing convection behind them in association with ongoing warm air advection. Through the morning hours ample lightning was associated with the storms along with heavy rainfall around 3 inches in the Fort Dodge area and 4 to 6 inches in the Des Moines area.
