 Brief Description: The tornado tracked south for about 4 miles along 97th avenue southeast, then turned to the southeast and tracked about 6 more miles before it crossed into LaMoure county about 2 miles north-northwest of Marion. One abandoned farmstead 10 miles west-northwest of Litchville was nearly swept clean of its buildings. Eight to nine buildings and 5 to 6 metal grain bins were swept away. At an occupied farmstead about 9 miles west of Litchville, the most damage was reported. The family was out baling hay at the time and were not hurt. The equipment they used to bale hay (three tractors and a baler) were the only things left unscathed by the tornado. Two houses, 5 outbuildings, a cattle barn, and miscellaneous farm equipment were all leveled. Machinery and debris were scattered across the yard and in the nearby pond and fields. A new pickup truck was demolished and sheet metal and metal support beams were wrapped around trees and vehicles. About 35 cows were killed, 20 grain bins were demolished, and a semi truck was overturned. The last F4 tornado in eastern North Dakota occurred on June 6, 1999, near Mountain, ND.

 Brief Description: EVENT NARRATIVE: The tornado touched down about 2 miles west-southwest of Northwood. The tornado crossed the Goose River about a mile west-southwest of the Northwood airport and left a 200 yard wide stretch of downed trees in its wake. By the time it hit the airport, the ground track was one-third of a mile wide and growing wider. At this point the tornado was still visible outside the increasingly heavy rain. The tornado reached an incredible width of eight-tenths of a mile as it pushed through Northwood to the east-northeast. At this point it had multiple vortices embedded in the overall wedge shaped tornado. The strongest of these vortices appears to have scoured the ground and left broad circulation patterns of debris in the overall damage and debris field. Around this time the tornado likely became wrapped in heavy rain and would have been difficult to observe from a distance. The most extreme damage appeared to be in the northeast corner of the community. Northwood, in southwest Grand Forks County, had a population of about 1000 people. 90 percent of the roughly 460 homes were damaged. One death occurred in a mobile home, with 18 other injuries reported. The death occurred in a trailer park on the north edge of town, where 19 total units were demolished. Just to the east of the trailer park, in the area that sustained the extreme damage, three businesses were hit particularly hard. An agricultural company, the towns largest employer, had its buildings heavily damaged. A nearby construction company lost two large steel buildings and other equipment. Steel beams from the two steel buildings were twisted and tossed nearby. Finally, a car dealership lost 15 to 20 vehicles from its parking lot along highway 15. Many of these vehicles were damaged beyond recognition and tossed into nearby fields. One corn field to the north of highway 15 (across from the 3 businesses on the northeast side of town) had it stalks snapped off several inches from the root bases, with pieces of husked corn laying around. Hangers and airplanes were also damaged at the airport. The local health center, school, supermarket, and grain elevator were damaged. Near the elevator, several rail cars were knocked off the tracks. Hundreds of trees were snapped, uprooted, or damaged. Power was also knocked out to many customers, but eventually was turned off (for safety reasons) to the entire town. A total of about 2600 truckloads of debris were hauled to the town landfill. In the days following the tornado, a Presidential Disaster Declaration was granted. EPISODE NARRATIVE: A cold front moved across North Dakota on the 26th, with a hot and humid airmass in place ahead of the front. At 6 pm CST, a surface low was located over southern Manitoba (Canada), just north of Pembina, ND. The cold front stretched to the southwest, back toward Devils Lake (ND) and Bismarck (ND). Ahead of the cold front, temperatures ranged in the low to mid 80s with dew points around 70F. Behind the front, temperatures did not cool significantly, but dew points dropped to the mid 40s. Thunderstorms began to form along and ahead of the cold front by early evening (from northeast ND into south central ND), eventually crossing into northwest Minnesota several hours later. Eight distinct tornadoes occurred over northeast North Dakota and northwest Minnesota during this event.

 Brief Description: EVENT NARRATIVE: This tornado began in Traill County about 3 miles north-northeast of Mayville at 349 PM CDT. The tornado crossed into Grand Forks County and tracked for an additional 8 miles to about 10 miles west of Thompson. The total track length was roughly 17 miles. One well constructed house near Holmes was completely swept from its foundation and destroyed along with several other farm buildings. Peak winds were estimated at 185 mph. EPISODE NARRATIVE: Conditions were ripe by the afternoon of the 17th for a major severe weather outbreak. A surface low had moved into east central North Dakota with an occluded front extending to the southeast. Warm and humid air was in place ahead of the front, with a much drier airmass pushing in behind it. The 500mb low was located over northwest North Dakota with a nice southwest to northeast upper jet pushing into eastern North Dakota. Two lines of convection formed by late afternoon, one from Roseau County down toward Eastern Otter Tail County and the other over east central North Dakota. Nearly all the cells that formed took on a classic hook shape with rotation very evident on radar imagery. Multiple tornado warnings were issued before the event wound down by mid evening. The strongest tornadoes were determined to be EF4 tornadoes, two in west central Minnesota and one in northeast North Dakota.

 Brief Description: EVENT NARRATIVE: This tornado continued into western Grand Forks County, where it dissipated 3 miles west-northwest of Logan Center at 716 pm CST. The total tornado track was about 6 miles long, with about 5 miles of this total occurring in Nelson County. The tornado destroyed a garage and farm outbuildings at 3 farmsteads. It killed 5 buffalo and completely dismantled a swathing combine. Trees were also snapped off or uprooted along the damage path and several empty metal grain bins were torn from their anchors and demolished. Gravel roads were deeply scarred by debris. Peak winds were estimated at 150 mph. EPISODE NARRATIVE: A cold front moved across North Dakota on the 26th, with a hot and humid airmass in place ahead of the front. At 6 pm CST, a surface low was located over southern Manitoba (Canada), just north of Pembina, ND. The cold front stretched to the southwest, back toward Devils Lake (ND) and Bismarck (ND). Ahead of the cold front, temperatures ranged in the low to mid 80s with dew points around 70F. Behind the front, temperatures did not cool significantly, but dew points dropped to the mid 40s. Thunderstorms began to form along and ahead of the cold front by early evening (from northeast ND into south central ND), eventually crossing into northwest Minnesota several hours later. Eight distinct tornadoes occurred over northeast North Dakota and northwest Minnesota during this event.

 Brief Description: EVENT NARRATIVE: By North Dakota standards this was a long lived tornado that covered many miles. A National Weather Service storm damage survey was completed in Rolette County on July 8, the day following the event. The storm survey concluded that the total path length was 17.6 miles, with a maximum width of 250 yards. The worst damage corresponded to low end EF3 on the Enhanced Fujita Scale, with maximum estimated winds of 140 mph. Multiple tornado sightings were reported by local officials and residents along Bureau of Indian Affairs (BIA) Highway number eight between 2:50 PM CDT and 3:10 PM CDT. The storm survey concluded that tree and structural damage along this corridor west and northwest of Belcourt corresponded to EF1 and EF2 on the Enhanced Fujita scale, or wind speeds ranging from 90 to 130 mph, with a path width ranging from 50 to 75 yards. Greater damage was surveyed north and northeast of Belcourt. Along BIA Highway number seven, a tornado path width of 250 yards was observed with significant widespread tree damage, corresponding to an EF2 rating or winds of 115 to 130 mph. Northeast of Belcourt along BIA highway number five, a home sustained heavy damage and there was one injury. Here, a rating of EF2 was assigned, with estimated wind speeds up to 135 mph. Storm reports around the immediate Belcourt area indicate a time of approximately 3:15 PM CDT for tornado impact. Seventy structures in total were impacted in the Belcourt area with varying degrees of damage. The tornadic storm continued east hitting the north side of the city of Rolla at approximately 3:30 PM CDT. Twelve homes were destroyed and 18 homes were damaged. The homes with the most significant structural damage corresponded to an EF3 rating. From this it was determined that the maximum wind speeds here were on the order of 140 mph. Two minor injuries were also reported in the Rolla area. The tornado continued east-southeast, hitting a farmstead east of Rolla which sustained structural and tree damage consistent with an EF2 tornado, or winds around 125 mph. The tornado then crossed US Highway 281 before pushing southeast into Towner County (See National Weather Service Grand Forks, North Dakota Storm Data from July 7, 2008). EPISODE NARRATIVE: In the early afternoon hours of Monday, July 7th, isolated thunderstorms developed over southwestern Manitoba, Canada, as a result of an upper level short wave trough tracking east across south central Canada. Maximized low level wind shear along a surface boundary over north central North Dakota, along with low lifted condensation levels, created a favorable environment for low level mesocyclones and the development of isolated tornadoes. The end result was a tornadic supercellular thunderstorm developing near Lake Metigoshe. It tracked east-southeast through northeastern Bottineau County and across northern Rolette County, before exiting into Towner County (Grand Forks, North Dakota County Warning Area) later in the afternoon. A storm survey conducted the following day found tornado damage in the Belcourt and Rolla areas, with the heaviest damage observed on the north side of Rolla. There were injuries from the tornadoes, but there were no deaths. Estimated damage was around one and a half million dollars.

 Brief Description: EVENT NARRATIVE: This tornado originated in Rolette County, where it produced EF3 damage near Rolla. It continued into Towner County for about 3 more miles and lifted about 11 miles west-northwest of Rock Lake. It produced mainly EF1 damage to scattered trees and fields in Towner County. Peak winds in Towner County were estimated at 90 mph. EPISODE NARRATIVE: An area of low pressure moved along the Canadian border on Monday (7th) and developed several severe thunderstorms. A triple point, or the intersection of multiple boundaries, formed in north central North Dakota, and resulted in several tornado reports.

 Brief Description: EVENT NARRATIVE: Meteorologists from the National Weather Service conducted a storm damage survey in and around Dickinson on Thursday, July 9th, 2009. Meteorologists walked through the area and spoke with numerous people affected, many of whom were eye witnesses to the event. This tornado passed through the city of Dickinson on the far south side, mainly just south of the Heart River. No witnesses spoken to actually saw the tornado. From their eye witness accounts, and from video obtained by the Dickinson Police Department, it is likely that this was a rain-wrapped tornado, and very difficult if not impossible to see. The tornado occurred before sunset, yet it was described as being as dark as night during the event. The conclusion of the damage survey was that this tornado touched down around a mile or so outside the city limits, on the southwest side, and moved east-northeast, passing through the far southern part of the city. It lifted back into the parent thunderstorm on the extreme southeast side of Dickinson near the city limit. This occurred in the window between 815 PM MDT and 830 PM MDT. Over 450 structures were damaged, of which nearly 100 were declared completely destroyed or beyond repair. Numerous vehicles were damaged or destroyed, some were on their roofs. Power lines were snapped, knocking out power to most of Dickinson, and tree damage was extensive. Two minor injuries were reported, with no deaths. The injuries were to a 23 year old male and a 42 year old male. Both occurred in homes. The worst damage surveyed was between the Heart River and roughly 8th Street Southwest and 8th Street Southeast in southern Dickinson. Of that damage, the absolute worst corresponded to middle EF3 on the Enhanced Fujita Tornado Scale. From that it was determined that peak wind speeds in the tornado were on the order of 150 mph. Other parts of Dickinson and the surrounding area sustained wind damage likely associated with the rear flank downdraft of the storm. EPISODE NARRATIVE: In the mid afternoon hours of Wednesday, July 8th, Tornado Watch 563 was issued for all of western and parts of central North Dakota, due to the expected widespread and dangerous development and rapid intensification of thunderstorms near a surface trough along the western North Dakota border. Destabilization along the surface trough, coupled with the approach of a strong upper level trough and an intensifying late afternoon/early evening low level jet, all contributed to the watch issuance. Later Wednesday evening, Severe Thunderstorm Watch 565 was issued for much of central North Dakota to replace the expiring Tornado Watch, and specifically to account for a developing bow echo which was expected to push east across the watch area into the early morning hours of Thursday, July 9th. The end result was a large severe weather outbreak experienced across much of west and central North Dakota, lasting from the late afternoon hours of the 8th, into the early morning hours of the 9th. Multiple severe thunderstorm and tornado warnings were issued. Numerous reports of large hail and severe thunderstorm wind gusts were received throughout this event. Several tornadoes occurred, including an EF3 within city limits on the south side of Dickinson. That tornado alone resulted in over twenty million dollars in damage.

 Brief Description: EVENT NARRATIVE: This tornado crossed from Burke County into Ward County. Note that for roughly three miles in the vicinity of the Des Lacs River, U.S. Highway 52 runs right on the Burke and Ward County line. The tornado was right on the highway in this area. This was the location of the worst damage with this tornado. Farm property on the north side of the highway, Burke County, and on the south side of the highway, Ward County, was impacted. One fatality and one injury occurred here, in a single automobile travelling along the highway, on the county line. The vehicle came to rest in a field, nearly 200 yards off the highway, on the south side of the highway, on the east side of the river, in Ward County. See the EF3 tornado entry for Ward County from August 12. This third tornado touched down just northeast of Bowbells, Burke County, and tracked east-southeast along U.S. Highway 52, and into Ward County where it dissipated. This EF3 tornado was spawned from the same supercell thunderstorm that earlier produced two brief and weak tornadoes in Burke County. Meteorologists from the National Weather Service conducted a storm damage survey on Friday, August 13, 2010. Meteorologists walked through the area and spoke with numerous people affected, some of whom were eye witnesses to the event. Significant damage occurred nearly six miles east of Bowbells, near the Des Lacs River, where U.S. Highway 52 is on the Burke and Ward County line. Three farms were impacted. The worst damage was on the Burke County side of the highway and west side of the river, where a farm home (DI 2, DOD 8) and six outbuildings were destroyed. Nineteen of 21 grain bins were also damaged or destroyed. In addition, a fifty foot air seeder connected to a cultivator, with a combined estimated weight near 60,000 pounds, was moved approximately 100 yards. Based on a lack of scratch marks in the ground it was determined that this equipment was picked up and carried through the air. A second farm, on the Ward County side of the highway, had trees in shelter belts snapped and uprooted and the chimney on the house damaged. A third house, this one on the east side of the river and the Ward County side of the highway, also had significant damage. Here, one camper was thrown into the river on the south side of the Highway 52 bridge that crosses the river, while another camper was thrown into the river and landed on the north side of the bridge, back into Burke County. The house had damage to siding and shingles. Of all the damage surveyed the absolute worst corresponded to a high EF3 on the Enhanced Fujita Tornado Scale. From that it was determined that peak wind speeds in the tornado were on the order of 165 mph. One fatality and one injury occurred in an automobile in this same immediate area. A car with two occupants travelling east along U.S. Highway 52 was picked up and carried over the Des Lacs River, and came to rest 200 yards off the highway, in a field east of the river, and on the Ward County side of the highway. The driver of the vehicle was injured and the passenger was killed. See the other two tornado entries for Burke County, and the EF3 tornado entry for Ward County from August 12 as this tornado crossed into Ward County. EPISODE NARRATIVE: A significant severe weather event evolved during the evening hours of Thursday, August 12th, and continued into the early morning hours of Friday, August 13th. Southwest flow aloft was in place across the Northern Plains region, ahead of an upper level trough over the Northern Rockies. A potent upper level impulse ejecting from the base of the trough provided the trigger for two areas of strong to severe convection. The first area was near a stationary boundary across southern North Dakota, where intense thunderstorm winds of 80 to near 100 mph were observed. The second area was ahead of a cold front over north central North Dakota, where an isolated tornadic supercell developed and spawned an EF3 tornado near Bowbells. Well into this event, Severe Thunderstorm Watch number 605 was issued across southwest and south central North Dakota in anticipation of a Mesoscale Convective System over southwest North Dakota tracking eastward along the South Dakota border area. By the time of the watch issuance, the tornadic supercell over north central North Dakota had dissipated. Multiple severe thunderstorm and tornado warnings were issued. Several reports of large hail, numerous reports of strong thunderstorm winds, and one confirmed EF3 tornado was received during this episode. The EF3 tornado tragically claimed one fatality. An automobile traveling east on Highway 52 was picked up and carried several hundred yards before being thrown into a field. Another person in the car was injured. In addition, a farmstead sustained heavy damage from the tornado, with severe damage observed to the home and several outbuildings.

 Brief Description: EVENT NARRATIVE: The tornado toppled a barn, severely injuring a horse. It tumbled farm outbuildings and toppled one high voltage power tower. The tower was made of steel and had four footings. Peak winds were estimated at 125 mph. EPISODE NARRATIVE: At 3 pm CST on the 15th, a stationary front was located from near Minot (ND) to Jamestown (ND) to near Sisseton (SD). South of the front, mid afternoon temperatures ranged in the mid 80s to lower 90s. To the north of the front, a meso-high had formed, with much cooler and drier air around it. The temperature across the boundary ranged from 89F at Minot, to 73F at Devils Lake, to 64F at Crookston. The upper air pattern had a western ridge and an eastern trough, putting the northern plains in northwest flow aloft. A strengthening upper jet also moved toward eastern North Dakota, giving this system good surface and upper level support. A supercell thunderstorm developed over southern Steele County around 530 pm CST and tracked across western Cass County and into eastern Ransom County before weakening after 7 pm CST. Then, another supercell thunderstorm formed over northern Steele County around 725 pm CST. This storm tracked just west of the path of the first storm, again mainly hitting central Steele County, western Cass County, and eastern Ransom County, before weakening around 915 pm CST. Both thunderstorms tracked south-southeast at speeds between 40 and 50 mph and spawned multiple tornadoes which were embedded within the overall downburst wind and hail pattern. The significant downburst wind and wind driven hail was seen in two partially overlapping paths, with each path from 5 to 7 miles wide and between 60 and 80 miles long (this damage path showed up clearly on satellite images). The strength of these winds is believed to have exceeded 80 mph with speeds over 100 mph in some localized areas. Hail sizes ranged from penny to hen egg sized. Most areas received considerable hail damage at the same time as the strong winds. Law enforcement officials and witnesses stated that the hail often persisted for longer than 5 minutes and completely covered the ground. The hail damaged roofs, windows, and siding in many homes along the damage path. Stripped and decimated corn, bean, and wheat fields were typical along the entire storm path too. The ND Farm Service Administration estimated losses occurred on over 700,000 acres in five counties. Total crop losses may exceed $250 million, with other property losses from $15 to $20 million. Cass and Steele Counties received a Presidential Disaster Declaration.

 Brief Description: EVENT NARRATIVE: The tornado plowed through wooden power poles and viciously ripped up mature trees over its damage path. The tornado also damaged a sturdy pole shed, where the sidewall was caved in and the roof and rafters were torn off. It tore the roof off and collapsed an older barn, then lifted and threw a well-built two car garage from its slab foundation. The tornado crumpled one steel, four footing, high voltage power tower. In combination with extreme downburst winds, the collapse of this first tower helped initiate the collapse of dozens more of these power towers. Peak winds were estimated at 130 mph. EPISODE NARRATIVE: At 3 pm CST on the 15th, a stationary front was located from near Minot (ND) to Jamestown (ND) to near Sisseton (SD).

 Brief Description: EVENT NARRATIVE: This tornado wrecked an antique wind charger windmill and downed some trees in Bentru Township (ND). It then crossed the Red River into Polk County, Minnesota, where it dissipated about 4 miles northwest of Eldred at 910 pm CST. The total path length was about 5 miles long, and about 2 miles of the total occurred in Grand Forks County. Peak winds were estimated at 120 mph. EPISODE NARRATIVE: A cold front moved across North Dakota on the 26th, with a hot and humid airmass in place ahead of the front. At 6 pm CST, a surface low was located over southern Manitoba (Canada), just north of Pembina, ND. The cold front stretched to the southwest, back toward Devils Lake (ND) and Bismarck (ND). Ahead of the cold front, temperatures ranged in the low to mid 80s with dew points around 70F. Behind the front, temperatures did not cool significantly, but dew points dropped to the mid 40s. Thunderstorms began to form along and ahead of the cold front by early evening (from northeast ND into south central ND), eventually crossing into northwest Minnesota several hours later. Eight distinct tornadoes occurred over northeast North Dakota and northwest Minnesota during this event.

 Brief Description: EVENT NARRATIVE: The tornado tracked northeastward for nearly 3 miles to around 8 miles east-northeast of Hope. Numerous trees were severely damaged in shelterbelts. An abandoned farmhouse was collapsed and other farm buildings were damaged. Peak winds were estimated at 125 mph. EPISODE NARRATIVE: Conditions were ripe by the afternoon of the 17th for a major severe weather outbreak. A surface low had moved into east central North Dakota with an occluded front extending to the southeast. Warm and humid air was in place ahead of the front, with a much drier airmass pushing in behind it. The 500mb low was located over northwest North Dakota with a nice southwest to northeast upper jet pushing into eastern North Dakota. Two lines of convection formed by late afternoon, one from Roseau County down toward Eastern Otter Tail County and the other over east central North Dakota. Nearly all the cells that formed took on a classic hook shape with rotation very evident on radar imagery. Multiple tornado warnings were issued before the event wound down by mid evening. The strongest tornadoes were determined to be EF4 tornadoes, two in west central Minnesota and one in northeast North Dakota.
