estimates that 500 hPa flow was around 80 knots from the WSW and that CAPE was from 1000–2000 J/kg. These conditions are similar to those found in other tornado outbreaks. Tornadic storms developed from 5:00-6:00 PM local time and while storm motions were to the NE, the prevalence of tornadic storms moved southward with the dryline/cold front intersection, lasting until 8:00 PM local in NW Missouri. A serial derecho then formed and moved across Iowa and Illinois through the nighttime hours, hitting Chicago in the early morning. Outbreak statistics Confirmed tornadoes March 21 event March 23 event Omaha, Nebraska The Omaha Easter Sunday tornado struck Omaha, Nebraska, at approximately 6:00 p.m. on March 23, 1913. The storm's path was reported as being wide and contained multiple vortices. The Omaha tornado followed the path of Little Papillion Creek as it entered the city.

Buildings were found chopped in half, pipes and supports dangling into space, such as the Duchesne Academy which was nearly obliterated. At North 24th and Lake Streets in the Near North Side neighborhood a large African American crowd was enjoying an Easter Sunday performance when the tornado flattened the building and killed more than two dozen people. Other brick structures in this small commercial district took similar hits, and more people died here than in any other part of Omaha. A streetcar running down North 24th Street in North Omaha encountered the tornado near this area. Thanks to the quick action of operator Ord Hensley in ordering passengers to lie on the floor of the car, everyone survived. Later, photographers would spot the wrecked machine and would call it the "Streetcar of Death", imagining that no one on board could have survived given the immense damage. The F4 tornado skirted the downtown
