Read the full account →A slow moving cold front entered the state and produced heavy rainfall across a large portion of central Iowa. The front eventually stalled, and transitioned to a northward moving warm front the next day.
Read the full account →A warm front extended east to west across the Upper Mississippi Valley on June 7, which provided the focus for thunderstorms producing excessive rainfall. In fact, these storms exhibited very high rainfall rates, which led to 1 to 2 inch rainfall amounts in an hour.
Read the full account →Heavy rainfall moved across the state with several locations receiving one to two inches of rain. Multiple convective complexes moved across the state on the 14th. The heavy rainfall caused some local flooding with minor river flooding in parts of central Iowa.
Read the full account →Continued heavy rain and high streamflows led to many rivers going back into flood in late May across central Iowa. Several crests occurred on the Des Moines River at Ottumwa.
