The National Weather Service reports s weak cold front will pass through Iowa late Saturday into Saturday Night bringing less heat to end the weekend, but it will also bring increased chances for thunderstorms. A few of these storms may be strong to severe but the extreme moisture content in the air will also produce conditions quite favorable for heavy rains. Rainfall amounts of 1 to 2 inches may occur from the Omaha area into northeast Iowa with locally heavier amounts possible. The risk area includes Atlantic, Audubon, Carroll, Corning, Council Bluffs, Denison, Greenfield, Guthrie Center, Harlan, Logan, and Winterset. Stay informed and be prepared for localized Flash Fooding.
