EF1 tornado in Lancaster County, Nebraska

This was the second tornado to track near the Raymond area from this event. This particular tornado had a path length of around 5.3 miles. The tornado was generally weak throughout the path but did remove the roof from a well built large outbuilding as it crossed North 14th Street at Branch Oak Road. Otherwise damage was confined to mainly tree damage.

One long-tracked supercell thunderstorm, and several other shorter-lived storms spawned tornadoes across eastern Nebraska during the late afternoon and evening hours of May 11th. The storms developed near the intersection of a warm front and dry-line/cold front in south central Nebraska then tracked northeast along the warm front toward the Lincoln and Omaha areas. Conditions in the area were very unstable with temperatures in the 80s to around 90 south of the warm front with dew point temperatures in the 60s. In total 12 tornadoes were recorded in the Omaha/Valley warning area with several others in the Hastings forecast area. The storms also produced very heavy rainfall which caused some flooding, mostly north through west and southwest of Lincoln.
