Showers and storms that tracked through the Southern Iowa Wednesday morning meant that a warm front in Missouri couldn't move northward. That kept the storms on Wednesday night in the southern half of the state. In turn, that meant that the highest tornado potential was not realized, since the warm and muggy air stayed out of the area. We did have enough energy to get strong storms and heavy rainfall in some areas. Central Iowa saw the worst with some radar estimates just northwest of Des Moines showing over a foot of rainfall overnight. Many reports of flooded roads, streets and basements are coming into the National Weather Service in Des Moines and Flash Flood Warnings are posted for that area through early morning. In the KWWL viewing area, the southern two-thirds of Benton County received up to 2 inches of rain and water was reported over Highway 218 south of Vinton overnight.
