 Brief Description: EVENT NARRATIVE: This is a continuation of the tornado that initially touched down in Burt county Nebraska, about 4.5 miles west of Little Sioux Iowa. The tornado eventually reached EF3 strength in Monona county when it hit a boyscout camp where 4 fatalities and 48 injuries occurred. The tornado crossed into Harrison county near mile marker 97 on Interstate 29 where a semi-truck was flipped. The tornado snapped power poles northeast of there with an estimated strength of EF2 in Harrison county. The tornado then crossed into Monona county Iowa about 4 miles north of Little Sioux. EPISODE NARRATIVE: A very strong and unseasonably cold upper level low pressure system that was tracking across the northern plains brought a strong low level jet to the region during the early morning hours of June 11th. The warm and unstable air that worked north into the region helped spawn early morning severe thunderstorms across eastern Nebraska and southwest Iowa. Later that day as the upper level system worked into the central Dakotas, a cold front pushed across the region. This helped set off another round of thunderstorms that developed over east central Nebraska by late afternoon. Isolated small supercell thunderstorms initially developed ahead of the cold front over eastern Nebraska, but they were quickly overtaken by a broken line of larger supercell thunderstorms, some of the heavy precipitation type, that developed along the cold front. Cell mergers and training were observed well into the evening hours as the activity quickly spread across southwest Iowa. The storms produced a total of 8 confirmed tornadoes in the Omaha/Valley warning area which covers eastern Nebraska and southwest Iowa.

 Brief Description: EVENT NARRATIVE: This tornado tragically hit a boyscout camp north of Little Sioux Iowa killing 4 young scouts. The tornado initially touched down in Burt county Nebraska, crossed into Harrison county Iowa near mile marker 97 on Interstate 29, and then finally crossed into Monona county Iowa about 4 miles north of Little Sioux. In Monona county the tornado entered the Little Sioux Scout Ranch, destroying the rangers home near the entrance of the park giving it a rating of EF3. The storm then blew down trees and destroyed bunk houses at the camp. Four scouts were killed in one bunk house when a brick chimney collapsed on them. In total 48 people were injured at the camp. The tornado continued to topple trees as it tracked into Preparation Canyon State Park. Just before it entered the park a farmstead sustained damage. The tornado hit another farmstead about 2.5 miles southwest of Moorhead where trees were blown down and sheds damaged. The tornado then began to weaken and finally lifted about 2 miles southwest of Moorhead. The total path length was around 14 miles.

 Brief Description: EVENT NARRATIVE: The tornado touched down near highway 30 about 1.5 miles west of the interchange between Interstate 29 and Highway 30, or about 3 miles west of Missouri Valley Iowa. The tornado was at its strongest and widest within a mile of its touchdown point, becoming weaker with more intermittent damage farther north. Near the touchdown point, a barn sustained roof damage and a windmill was knocked down. One-half mile north of Highway 30, 54 empty grain rail cars were derailed. One mile north of Highway 30, along 305th St., two residences were impacted by the tornado. A 100-year-old single family residence directly in its path was completely destroyed, with all walls collapsed and debris relocated about 50 feet north of the foundation. The debris collected over the site of a cinder block garage, which also partially collapsed. About 100 yards north of the garage site, a machine shed was collapsed onto a combine inside, which had been moved by the wind. Trees near the house sustained some broken limbs and treetops, and a power pole was snapped. The damage at this site was given an EF2 rating. Another residence one-quarter mile to its west sustained minor siding and shingle damage and windows were broken. Seven of the eight outbuildings at that residence were collapsed, with debris strewn into nearby fields. Damage at the two houses indicated a path width of one quarter mile at that point, the widest along the path of the tornado. The tornado continued northward, overturning two semis on Interstate 29. From there to a point about 3 miles southwest of Magnolia, near the intersection of the Loess Hills Trail and Melody Oaks Trail, intermittent light damage to trees and roofs of a couple of outbuildings was noted. From this point, the survey team determined the damage path narrowed to 100 yards or less based on scattered tree and outbuilding damage, with EF0 intensity north of Interstate 29. EPISODE NARRATIVE: An intense upper level low pressure system tracked from eastern Colorado into southeast South Dakota from March 23rd to 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 and 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 between 50 and 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 60 mph for several hours across parts of eastern Nebraska.

 Brief Description: The stronger of the 2 tornadoes that ripped through Harrison county the afternoon of 5/16/99 killed 2 people and destroyed 6 homes and a bridge before it dissipated a couple of miles east of Logan. A family of 5 leaving a high school graduation party encountered the tornado on a road around 6 miles northeast of Missouri Valley and took cover in a ditch about the time the path of the tornado widened to a quarter mile. Two of them were killed after their car and a 3-ton combine head were thrown on them. There were also numerous flipped or smashed vehicles in this area. F37OU, F15OU

 Brief Description: EVENT NARRATIVE: This is the continuation of tornado number 1 (of 2) to hit the Omaha metro area this night. Tornado number 1 crossed over from Sarpy county near 144th and Harrison Streets before merging with tornado number 2 just east of 132nd and Westwood Lane. From there the merged tornado continued northeast to near 114th and Shirley Streets. Tornado number 1 traveled at about 50 mph in Douglas county. Tornado number 1 produced EF2 damage in both Douglas and Sarpy counties. Although tree and roof damage was noted along most of the track, the area hardest hit in Douglas county was around 137th and Y Streets. A few homes had their roofs completely blown off in this area, while others had significant roof and siding damage. The tornado then hit a Walmart, Sams Club and Home Depot causing damage to each of those businesses after it crossed L Street. Tornado number 1 first set down just southeast of 232nd and West Angus Road about a mile west of Gretna in Sarpy county. It traveled about 8 miles in Sarpy county before crossing into Douglas county. The tornadoes spun up on the leading edge of a bow echo that gathered strength and raced through the Omaha metropolitan region. OPPD reported that 13,800 customers lost power from the storm. In total, more than 500 homeowners reported damage from the storm and according to FEMA, 7 homes were destroyed and 21 others sustained major damage. 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.

 Brief Description: As was mentioned above, the weather pattern was very active over the central U.S. A cold front had become stationary to the west of Iowa during the afternoon of the 16th. This set the stage for a serious weather situation. During the afternoon, 70 degree F. surface dew point temperatures were widespread for the first time of the season. The airmass became very unstable as the upper levels were still relatively cool. CAPE values during the few hours just prior to the development of the thunderstorms were in excess of 5000 J/kg. The situation became explosive as thunderstorms formed along and just ahead of the cold front over western Iowa. A little later in the afternoon, thunderstorms formed over northeast Iowa along the nose of the low level jet and just north of the surface warm front. These two features combined to produce a variety of severe weather across much of Iowa. The first of the severe weather broke out over west central Iowa. This was on the form of tornadoes. The strongest tornado in the Des Moines CWA touched down in Crawford County near Ricketts. The tornado was F2 strength and caused damage to 10 farmsteads along the way. One farmstead reported the house as being destroyed. The tornado had a duel structure with the two tornadoes about 2.5 miles apart north and west of Ricketts. This tornado was on the ground from near the western county line to a point north of Deloit. This was by far the strongest tornado in the CWA. There were several brief touchdowns and one that was on the ground for a couple miles, west of Denison. During the late afternoon and early evening hours, there were several reports of brief touchdowns from west central into central Iowa. One tornado touched down briefly in Audubon County, another southeast of Bedford in Taylor County destroyed a trailer there and tore a roof off of a shed. Another tornado touched down briefly in rural areas west of Perry in Dallas County. The tornado did little damage however. The same storm knocked down power lines and trees south of Perry as winds were recorded at around 70 MPH a short time later. The final touchdown was brief near Ames, in Story County. There were a few reports of high winds as the line in western Iowa transformed into more of a bow echo structure. A 67 MPH wind gust was recorded at the Creston Airport in Union County. As the storms moved across Dallas County, winds of around 65 MPH blew trees down on a commercial chicken house, killing 5000 laying hens. Winds gusted to 61 MPH at both the NWS office in Johnston and at nearby Ankeny, both in Polk County. As the bow echo continued to move north and east, winds around 65 MPH swept through the Marshalltown area. Damage was reported at a trailer court there as the skirting on some of the trailers was torn off and one of the trailer houses was nearly blown off its supports. The line of storms and high winds made its way northeast into the Wellsburg area of Grundy County, causing extensive damage on a farmstead just southeast of the town. Hail was widespread with all of the thunderstorms as they moved across the state. Many areas reported hail nearly dime size. Reports of hail of up to an inch were quite common as well. Some of the larger hail reports included golf ball size hail in Cass County at Atlantic and baseball size hail reported at both Boone in Boone County and south of Plainfield in Bremer County. Once the severe weather started to wind down, flash flooding was a fairly widespread problem, especially near the warm front over that was over northeast Iowa. The storms associated with the cold front produced flash flooding in Cass County at both Atlantic and Griswold. For the most part, the storms with the cold front were moving too quickly to cause much in the way of flooding, though urban flooding was reported in some areas. The big flooding was over the northeast part of the state. Those areas were hit twice with heavy rain and severe weather, once in the morning and once with this event. Widespread flash flooding took place in Black Hawk, Bremer, Butler, and Hardin Counties. Rains of 4 to 6 inches for the day were common in these areas, as well as areas to the northeast of that. Governor Vilsack declared 12 Iowa counties disaster areas. Butler, Bremer and Black Hawk Counties in the Des Moines CWA were declared disaster areas. All of these same counties were later declared Presidential Disaster Areas. Some of the more serious damage in the Central Iowa CWA was in Black Hawk and Bremer Counties. In Black Hawk County, U.S. Highway 218 was closed for a time by flooded water. The Cedar River caused considerable flooding in the area. The town of Dunkerton was approximately 50% evacuated as waters rose. The Sewage plant there was inundated by the high water. There was damage caused to many public roadways around the county. Some of the bridges over smaller creeks were declared unsafe. The County Engineer stated damages in Black Hawk County were at least $1,200,000, including $560,000 in damage to ditches, roads, culverts, and bridges. Damage in the town of Dunkerton were placed at $500,000 to public infrastructure. The county also reported $183,000 in damages to parks. In Bremer County, numerous homes in the town of Tripoli reported sewer backups into the basements. In the town of Denver, 25 homes reported at least 6 feet of water in the basement. Of those 25 homes, five of them had basement wall damage. Fifteen business in the town had anywhere from 2 inches to 8 feet of water in the basement. Bremer County reported damages to 19 culvert sites, 55 road sites, 2 bridge abutments, and 8 driveway washouts. Damage from these items alone were at least $200,000. In Butler County the county Engineer reported 20 to 30 sites affected with estimated damage of $150,000. One Bridge sustained at least $60,000 damage. Needless to say, numerous county and state roads were under water and closed as well throughout the area. The flooding in these areas was described as worse than the flooding in 1993. In many areas it was worse than the record floods of 1968. Farther to the southwest flash flooding also occurred in Cass County. Damage was not as serious there as the amount of rainfall was not as great. One basement was completely flooded in the town of Griswold. Flooding was serious enough in Atlantic to not only flood several homes but also buckle the pavement on one of the streets in town.

 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.
