A potent storm system moved across central Indiana late on February 27 and early on February 28. Warm and moist air moved into the area with the system, and this allowed thunderstorms to develop. Some of the storms produced hail, damaging winds, heavy rain, and one storm produced a tornado near the town of Ingalls.
In addition to the tornado damage, downburst straight-line wind damage was also observed just south of the tornado touchdown near Woods Drive at State Road 67.  Additional downburst straight-line wind damage in the form of downed trees, limbs and power lines occurred further southwest on State Road 67 in Fortville at Motel Road, Industrial Drive and just north and west of the downtown area.
Northern sections of central Indiana saw 1 to 3 inches of rain, with isolated 4 to 5 inch amounts. This rain, combined with water from a melted snow cover, led to flooding of numerous streams, creeks, and rivers. Flooding also occurred in low lying areas. Some creeks and rivers experienced record flooding.
