The 2010 Tyler–Doran tornado was a violent EF4 tornado that touched down near the community of Tyler in Richland County, North Dakota, on the evening of August 7, 2010. It crossed into Wilkin County, Minnesota, before dissipating near the town of Doran. The tornado was one of eleven reported in the Dakotas and Minnesota that day, and it became the most intense of the outbreak.[1]
Background
On the morning of August 7, 2010, the Storm Prediction Center (SPC) issued a Day 1 Convective Outlook highlighting the potential for severe weather across the northern Plains. Eastern North Dakota and western Minnesota were placed under a 5% tornado risk area, along with a broader 30% wind risk extending into eastern North Dakota, central and western Minnesota, and western Wisconsin. In addition, a 30% hatched hail risk was outlined for eastern North Dakota and western Minnesota, where very large hail was considered possible.[2]
The SPC noted that boundary-layer moisture, strong daytime heating, and a mid-level disturbance would combine to create a favorable environment for severe thunderstorms. Mixed-layer CAPE values of 2000–3000 J/kg and effective shear profiles supported the potential for supercells capable of producing very large hail and isolated tornadoes, before evolving into a damaging wind-producing mesoscale convective system later in the evening.[3]
Meteorological history
The tornado developed around 6:25 p.m. CDT approximately 10 miles south of Wahpeton, North Dakota.[1] Initially rated EF3 in North Dakota, it destroyed seven farm buildings and caused extensive tree damage. After crossing into Minnesota, the tornado intensified to EF4 strength, obliterating additional farmsteads and scouring agricultural fields.[1] A Ford pickup truck was thrown from one farm site, with its engine block found two-thirds of a mile away. The tornado dissipated at 6:47 p.m. CDT, with a total path length of roughly 5 miles (8.0 km) and a maximum width of 600 yards (550 m).[1]
Impact
Damage was concentrated in rural areas. Fourteen farm buildings were destroyed across the tornado’s path, with numerous others sustaining heavy damage.[1] A sugar beet field in Wilkin County was scoured, with plants uprooted and debris scattered. Despite the intensity of the tornado, no fatalities or injuries were reported.[4][circular reference]
Surveying
Following the tornado, damage surveys conducted by the National Weather Service and documented in regional summaries confirmed the path, intensity, and signature damage patterns. The tornado was tracked for approximately 2.5 miles (4.0 km) in Richland County, North Dakota, at EF-3 intensity, before crossing into Wilkin County, Minnesota, where it strengthened to EF-4 level in a final 2.5-mile segment—bringing the total path length to 5 miles, with a maximum width of 600 yards (550 m) and a duration of roughly 22 minutes. In Minnesota, the tornado obliterated seven farm buildings, heavily scoured a sugar-beet field, debarked trees, and hurled a Ford pickup truck such that its engine block landed nearly two-thirds of a mile away. These findings were confirmed by SPC/NCDC data and summarized in regional reports including an NWS Grand Forks–derived summary and the Tornado Talk overview.[5][6][circular reference]
