 Brief Description: EVENT NARRATIVE: This tornado started approximately 4 miles east of Falls City and traveled north northeast. Soon after the initial touchdown there was damage to the roof of a home and a church. The tornado then produced tree damage before blowing the roof off of a home and destroying several sheds and barns at another farmstead. Other tree, house, outbuilding and power pole damage was observed along its path before it crossed the Missouri River into Holt county Missouri. The damage path reached a half mile wide where high tension power poles were snapped northeast of Falls City. EPISODE NARRATIVE: A warm front and low pressure system over northern Kansas lifted northeast into southeast Nebraska and southwest Iowa as an unseasonably strong upper level low pressure system lifted from the Rockies into the northern plains. The front and upper level disturbance caused fast moving thunderstorms, a few severe, to develop during the late morning hours in northeast Nebraska. After a brief lull in the activity through early afternoon, additional thunderstorms developed over eastern Nebraska. The storms developed along 2 lines, one extended north of Columbus while the other stretched from southeast Nebraska into southwest Iowa. Several of the storms turned severe, including one supercell that produced an EF2 tornado in extreme southeast Nebraska. Besides the severe weather, a few of the thunderstorms produced additional areas of heavy rain that fell on saturated soils and caused some already high rivers to flood.

 Brief Description: EVENT NARRATIVE: This is the second of 5 cyclic tornadoes that a low-topped supercell thunderstorm produced at it tracked southeast through east of the Lincoln area. This tornado touched down around 2 miles east of Hickman and damaged a house in the area, destroyed some farm outbuildings, took the roof off of a barn and also caused tree damage. EPISODE NARRATIVE: An intense upper level low pressure system tracked from eastern Colorado into southeast South Dakota from March 23rd into March 24th. This caused a surface low pressure system to move from western Nebraska into southeast South Dakota during that time. As the low tracked northeast, a dry-line moved into eastern Nebraska during the afternoon of March 23rd. With surface temperatures in the 60s and 70s, and dewpoint temperatures in the 50s, ample instability was in place to allow a line of severe thunderstorms to develop as the dry-line punched eastward. Several fast moving low-topped supercell thunderstorms were embedded in the line, and one cell produced cyclic tornadoes from southeast of Lincoln into western Iowa. The storms in the line were moving north northeast at 50 to 60 mph. In addition to the severe weather, strong southerly gradient winds prevailed ahead of the low pressure. In some cases the winds gusted between 50 and 65 mph for several hours across parts of eastern Nebraska.

 Brief Description: EVENT NARRATIVE: A bow echo that moved across the Beatrice area spun up an EF2 tornado just north of town while south through east of town a narrow path of straight line wind damage occurred. The tornado touched down around 2 miles east of Highway 77 near Hackberry Road where it severely damaged two houses. Farm outbuildings were also severely damaged or destroyed. The tornado was rated an EF2 at that location. From there the tornado damaged a church on Elm Road with trees also snapped or uprooted in both areas as well. The tornado continued east northeast causing substantial tree and outbuilding damage to 10 more farmsteads, along with some house damage. Most of the damage occurred along Hackberry Road with the damage path around 1/4 mile wide. As the tornado worked its way east northeast toward Johnson county...the damage gradually weakened and the path narrowed. The tornado was estimated to have lifted a little northeast of Filley. Emergency management estimated that the tornado and the wind damage south through east of town caused at least a million dollars worth of damage. EPISODE NARRATIVE: A warm front lifted north across the region during the afternoon and evening of May 29th followed by a weak cool front passage later that night. As the warm front passed, temperatures warmed into the lower to mid 80s and dewpoint temperatures climbed into the 65 to 70 degree range. The whole system was aided by an intense upper level low pressure area that moved from the eastern Rockies into the northern plains. The combination of the high instability in place, the 2 fronts and the upper level disturbance created conditions that were favorable not only for severe thunderstorms, a few of which were supercells that produced tornadoes, but also areas of very heavy rainfall that produced flash flooding that night and river and stream flooding that lasted a day or two later.

 Brief Description: See description below. F73PH This long tracked tornado is often referred to as the Hallam tornado. It initially touched down 3 miles west of Daykin in northern Jefferson county. The tornado was rated an f0 or f1 in Jefferson county damaging farm outbuildings, grain bins and trees. From there the tornado crossed into Saline county southwest of Western and remained an f0 or f1 until it struck the southern portion of Wilber where it strengthened to f2. Roofs were blown off of homes just southeast of Wilber. The tornado traveled from Wilber into Gage county, crossing the county line west of Clatonia where it grew to its most intense stage, f4. The tornado remained nearly at this strength as it crossed into Lancaster county near Hallam with a damage path of around 2 1/2 miles. Many well-built homes were demolished from Clatonia to Hallam, along with grain bins, farm sheds, and outbuildings. Many trees were destroyed or uprooted. Although Hallam itself escaped the strongest winds from the storm, which occurred just south of town, 95 percent of the buildings in town were either destroyed or severely damaged. The lone fatality from the tornado occurred in Hallam. The storm also toppled several hopper cars from a freight train on the west edge of town. In total 55 railroad cars were derailed. From Hallam the tornado traveled east for several miles prior to turning northeast again just north of Cortland. The storm then tracked 2 miles north of Firth, severely damaging the Firth-Norris high school and a nearby middle school. School busses were tossed in this area. Several homes northeast of the schools were flattened as the tornado regained its f4 strength. The damage path continued northeast to Holland and then to 2 miles north of Panama where the tornado weakened to around an f2 and the damage path began to narrow. The track then curved more toward the north, passing just south of Bennet where a few homes sustained f3 damage. After passing south of Bennet, the storm moved back to the northeast and began to weaken to f0 or f1 strength as it crossed into Otoe county southwest of Palmyra. The tornado finally dissipated 1 miles west southwest of Palmyra. In total the tornado was on the ground for around 54 miles with a maximum intensity of f4. Besides the fatality, 38 people sustained injuries, 158 homes were leveled and 57 others were seriously damaged. The dollar amount of damage was estimated at 160 million, with 60 million of that agricultural including 100 cattle and 50 hogs lost. Some 150,000 acres of crop land sustained significant damage. The 5 counties were declared national disaster areas by Fema.

 Brief Description: This tornado formed about 6 miles west of Wymore at 433 pm CDT (1533 CST), tracked northeast to around 4 miles east of Beatrice where it caused f2 damage, then tracked just south of Adams and crossed into Johnson county 2 miles southeast of Adams around 515 pm CDT. In Johnson county the tornado tracked another 5 miles before dissipating or lifting 3 miles north of Sterling. This tornado formed from a supercell which then became rain-wrapped and took on a heavy rain (hp) supercell characteristics. In Gage county, the average width of the damage path of the tornado was around 150 yards, but it did reach around 1/2 mile in a 3 mile stretch from 4 miles east of Beatrice to 6 miles east northeast of Beatrice. The total path length in Gage and Johnson counties was 34 miles. Seventy-three homes were affected by the tornado, one house was basically destroyed and two others received major damage. One farmstead had 10 trees uprooted. The tornado also destroyed two large chicken houses that when full could house up to 86,000 broilers. In Gage county the damage was estimated at $4.5 million.

 Brief Description: The beginning of the tornado started 4 1/2 miles west northwest of downtown Beatrice, just north of the Homestead National Monument. The storm damaged trees just north of state highway 4 when it struck several homes, primarily lifting the roofs off of them. The tornado was rated F1 at that point. Around 1/2 mile to the east, the tornado struck a subdivision. The damage was more severe, with collapsed outer walls and roofs off homes. The tornado damage was rated as a strong F2 in this area. The tornado, continuing to move in an east southeast direction, nearly paralleling highway 4, struck a church. Part of the roof was lost off the church. After striking the church, the tornado hit several more homes and barns before entering the heart of the city. The damage path width of the tornado was 1/4 to 1/2 mile wide, with damaging thunderstorms winds out to 11/2 mile. The main tornado path remained 1/4 to 1/2 mile wide north of U.S. highway 136, with much of the damage south of highway 136 due to thunderstorm downburst winds. The tornado strength weakened when entering the city, with an F-scale strength between F0-F1. Although much of the damage in the central city area was due to falling trees and large tree limbs, other damage noted was roofing torn off of several buildings and a collapsed 200 foot communication tower. After the storm exited the city, it regained strength. The tornado also began curving to the northeast. The storm maintained about F1 strength from about 1 mile east of downtown Beatrice to the storm's dissipation, approximately 3 miles northeast of the city. The strong F2 tornado's path was 9.5 miles long.

 Brief Description: See description below. This long tracked tornado is often referred to as the Hallam tornado. It initially touched down 3 miles west of Daykin in northern Jefferson county. The tornado was rated an f0 or f1 in Jefferson county damaging farm outbuildings, grain bins and trees. From there the tornado crossed into Saline county southwest of Western and remained an f0 or f1 until it struck the southern portion of Wilber where it strengthened to f2. Roofs were blown off of homes just southeast of Wilber. The tornado traveled from Wilber into Gage county, crossing the county line west of Clatonia where it grew to its most intense stage, f4. The tornado remained nearly at this strength as it crossed into Lancaster county near Hallam with a damage path of around 2 1/2 miles. Many well-built homes were demolished from Clatonia to Hallam, along with grain bins, farm sheds, and outbuildings. Many trees were destroyed or uprooted. Although Hallam itself escaped the strongest winds from the storm, which occurred just south of town, 95 percent of the buildings in town were either destroyed or severely damaged. The lone fatality from the tornado occurred in Hallam. The storm also toppled several hopper cars from a freight train on the west edge of town. In total 55 railroad cars were derailed. From Hallam the tornado traveled east for several miles prior to turning northeast again just north of Cortland. The storm then tracked 2 miles north of Firth, severely damaging the Firth-Norris high school and a nearby middle school. School busses were tossed in this area. Several homes northeast of the schools were flattened as the tornado regained its f4 strength. The damage path continued northeast to Holland and then to 2 miles north of Panama where the tornado weakened to around an f2 and the damage path began to narrow. The track then curved more toward the north, passing just south of Bennet where a few homes sustained f3 damage. After passing south of Bennet, the storm moved back to the northeast and began to weaken to f0 or f1 strength as it crossed into Otoe county southwest of Palmyra. The tornado finally dissipated 1 miles west southwest of Palmyra. In total the tornado was on the ground for around 54 miles with a maximum intensity of f4. Besides the fatality, 38 people sustained injuries, 158 homes were leveled and 57 others were seriously damaged. The dollar amount of damage was estimated at 160 million, with 60 million of that agricultural including 100 cattle and 50 hogs lost. Some 150,000 acres of crop land sustained significant damage. The 5 counties were declared national disaster areas by Fema.

 Brief Description: The longest track tornado of the day moved southwest to northeast across Nemaha county miraculously producing no deaths or injuries. However significant damage occurred to about 20 different farms or farmsteads and related business, machinery and buildings. The tornado just missed populated areas and remained generally in fields and farm areas. Excessive rain in the days after the storm hampered cleanup. Property damage from the tornado was estimated at $1.1 million. In some areas the tornado was about 1/2 mile wide while in other areas damage was only about 100 yards wide. At times the tornado had multiple vortices.

 Brief Description: EVENT NARRATIVE: This was the first touchdown of 2 tornadoes that hit the Omaha metro area this night. Tornado number 1 started just southeast of 232ND and West Angus Road about a mile west of Gretna. A garage was demolished at this point, suggesting EF1 damage. The tornado moved east northeast at 45 mph and produced scattered EF0 damage in Gretna with tree and shingle damage noted. From there tornado number 1 continued northeast to near 156th and Giles Road. EF 2 damage was noted just southwest of that point with major roof damage to a home. The tornado then crossed over into the Millard area of Douglas county where it continued for about 3 more miles before merging with tornado number 2. Tornado 1 also caused EF2 damage in Douglas county with much of it concentrated in the vicinity of 137th and Y Streets. The tornadoes spun up on the leading edge of a bow echo that gathered strength as it raced through the Omaha metropolitan area. More than 500 homeowners reported damage from the storm and OPPD reported that 13,800 customers lost power. EPISODE NARRATIVE: As one unseasonably strong upper level system lifted into Canada another one dropped down behind it across the northern Plains. This caused surface low pressure to develop over northeast Kansas along a cold front that was crossing the plains. This in turn caused the front to slow down as it moved into southeast Nebraska and southwest Iowa. A small line of thunderstorms that had developed along the front moved ahead of it and encountered a strong low level jet. The combination of the low level jet, and a warm front that extended east of the low, strengthened the line segment just to the southwest of Omaha and causing it to bow out. In turn a few quick moving spin-up circulations and 2 tornadoes developed as the bow echo crossed the Omaha area. Although these tornadoes hit in the middle of the night and caused significant damage in the Omaha area, there were no deaths or serious injuries with the storm. The system also produced areas of heavy rain which caused some flash flooding and then eventual river flooding.
