Environment
A potent shortwave disturbance (Fig. 1) over ern North Dakota the afternoon of July 28th headed east into northern Michigan overnight. A very moist and very unstable airmass developed south of this system and became explosively unstable by late day due to strong heating in the warm sector (Fig. 4). Storms initiated late day in two areas, in eastern Minnesota ahead of the upper wave, and across northern Iowa north of the sfc warm front extending eastward out of low pressure in eastern Nebraska. Morning storms across the Great Lakes left behind an outflow boundary (Fig. 8) which led to additional thunderstorm development toward sunset across Indiana. Storms quickly became severe, especially over Iowa where a Bow Echo developed Thursday evening in response to abundant shear and instability (Figs. 3/4). That Bow Echo then marched east across Illinois, Indiana and Ohio producing widespread damaging winds and several tornadoes. Given the very moist atmosphere in place (Figd. 2/6) it was no suprise that very heavy rain resulted especially over northwest Indiana and southwest Michigan with local amounts there exceeding 6 inches in places.
