Thursday marks the 10th anniversary of a tornado that destroyed most of the Lancaster County town of Hallam, Nebraska.
The 2.5 mile-wide F4 twister struck on the evening of May 22, 2004, killing a 73-year-old woman and injuring 37 others. The tornado stayed on the ground for more than 10 minutes and covered a path of 52 miles.
That storm system spawned 19 confirmed tornadoes, leveling 158 homes and damaging dozens of others. Gage, Saline, Lancaster and Cass counties were designated federal disaster areas.
