EF1 tornado in Miami County, Indiana

A NWS survey of damage indicated a tornado touched down northeast of Denver, near the intersection of N Warsaw Trail and E County Road 800 N. The tornado remained over open fields for part of its time, doing crop damage along its path. Some trees were either snapped or uprooted. A poorly anchored, older barn was destroyed near the intersection of N County Road 600 East and E County Road 900 N. The tornado lifted shortly after crossing 900 N. Maximum winds were estimated at around 90 mph.

Synoptic quasi-stationary boundary was located across the forecast area, initially across northern parts during the morning and then sagging south as an upper level wave moved into the region during the late afternoon and evening hours. A morning complex of storms caused sporadic wind damage as well as some areal flooding. Subsidence behind the system kept any further development of storms limited until the approach of the wave. This wave, combined with the front and instability advected in from central Illinois all set the stage for increasing thunderstorm development. Several supercells developed, producing long lived wall clouds and two confirmed tornadoes. IN addition, training of convection caused flash flooding in some parts of Indiana and Ohio.
