Separate lines of thunderstorms swept across central Indiana producing numerous large hail and damaging wind reports as a strong low pressure system moved across the state during the afternoon of April 20, 2000. In addition, a single thunderstorm moved across in the early morning producing golfball size hail near Pendleton. The first line of thunderstorms moved across northwestern parts of the IND CWA just before noon producing penny to golfball size hail across Tippecanoe, Carroll and Warren counties. The second line produced large hail but more notably damaging winds across the center of the IND CWA. The worst damage was near Bloomington, Terre Haute, Lebanon and Nineveh in Johnson county. Structural damage occured across these areas.  In Bloomington, 1 person was injured as three mobile homes were blown off their foundations from winds estimated up to 70 mph.
