A tropical air mass worked north out of the Gulf states as weak low pressure deepened and moved into the western Great Lakes. The high moisture content, combined with very efficient rainfall processes allowed for a period of widespread rain across the forecast area. As the main area moved north, additional stronger showers developed and moved over the same area, across northwestern Marshall county into much of St. Joseph County Indiana. Localized rain amounts exceeded 8 inches. In addition to the flooding, a low topped supercell raised havoc mainly across portions of central Indiana. The supercell moved into portions of Grant, Wabash and Huntington counties were numerous funnel clouds sighting were reported and recorded. More detail on all of these events can be found throughout the web page.
