An unusually strong upper level low pressure system and surface cold front moved through central Indiana during the late morning and afternoon hours of June 10th.  A very humid air mass was in place behind a tropical system that had passed through.  This combined with the strong dynamics allowed for storms with very strong wind gusts and some large hail to form.  The strongest storms were north and east of the forecast area. Numerous reports of winds up to 70 mph and hail as large as an inch occurred with this storm system.  The most severe damage occurred in portions of Tipton and Howard counties.
