There is a small (30%) chance for additional storms this afternoon. Some of these may (5-15%) be severe, but this risk is confined to areas mainly south of US Highway 18 in northeast Iowa and southwest Wisconsin.
Any thunderstorms that develop this afternoon (30% chance) will be capable of producing heavy rain and additional flooding. The good news is that the area at risk for this looks to only encompass about half the region, with the highest level of risk - a level 2 out of 5, confined to central Iowa.
Additional showers and thunderstorms are expected over the next several days. Don't drive through flooded roads.
