As a powerful shortwave trough dropped into the northern United States and move east-southeast, the stage was being set for a multi-day tornado outbreak in the upper Midwest. The Storm Prediction Center had every day on its 4-8 outlook marked for severe weather on June 5. June 8 featured high instability and good shear, but a cap that didn't erode until mid afternoon. The SPC had an enhanced risk with a 10% hatched tornado risk in place for much of central and east North Dakota and South Dakota, with a 5% risk extending into northern Nebraska. 24 tornadoes touched down that day, including one EF4. The most prolific day of the outbreak took place on June 9. A strong surface low was located near the North Dakota/Minnesota border, with a cold front draping down through west MN into northern IA. A warm front in central/north MN was also expected to be a focus for tornadic activity later that day. 0-1 km helicity was in the 300-500 m2/s2 range and MLCAPE exceeded 4,000 j/kg in some spots. The SPC issued a moderate risk with a 15% hatched tornado risk for much of central and southern MN, which was eventually upgraded to a high risk at the 1630z outlook, the third high risk of 2020. A PDS tornado watch was issued and several long-tracked, intense supercells developed spawning 55 tornadoes, including 8 EF4's. After dark, storms congealed into an MCS, and several QLCS tornadoes occurred across Wisconsin. By morning, the MCS had weakened, and rapid destabilization occurred in north Illinois and southern Wisconsin. The surface low had moved southeast quite a bit, now positioned in northeast Iowa. Again, a moderate risk was issued with a 15% hatched tornado risk. 31 tornadoes touched down, including two EF4's, one of which had a path length of about 91 miles. A high-end EF2 tornado tracked through western Chicago. Activity became sloppy and another MCS formed late that evening, but it weakened before dawn on June 11. Another moderate risk was issued that day. The surface low was located in extreme southwest Michigan, and the whole warm sector was primed for supercells and tornadoes. 32 tornadoes touched down, including two EF4's. Some areas hit in the Tornado outbreak of April 23, 2020 less than two months earlier were hit again in this outbreak. 41 people died in the outbreak, and it left $2.66 billion in damages. It joins similar outbreaks, such as the June 2, 1990 outbreak, June 16, 1992 outbreak, and June 17, 2010 outbreaks as one of the most intense June outbreaks ever recorded. 142 tornadoes were confirmed over the four day span, 13 of which were violent, making it one of the most active periods of tornadic activity on record. It is the only recorded instance of four straight days with violent tornadoes. Only five days in recorded history since 1950 had more violent tornadoes than June 9th.

Along Horseshoe Lake, trees were slightly debarked and snapped and a small boat was tossed nearly 100 yards. At this point it became heavily wrapped in rain and weakened quite a bit, doing mainly EF1 damage to trees and outbuildings. It eventually reached Motley, where high-end EF2 to EF3 damage occurred again to buildings on the western half of town. It entered Cass County and dissipated shortly afterwards.
EF3 N of Olivia to SE of Buffalo Renville, Meeker, McLeod, Wright 2117 65.12 mi As the Renville EF4 was ending, the same supercell produced another long-tracked intense tornado.

EF4 NE of Thomson to Carpentersville Carroll, Ogle, DeKalb, Kane 2011 91.18 mi 1 death - This large and violent wedge tornado had the longest path length of any tornado in this outbreak. Spawned by the first of two long-tracked cyclical supercells in north Illinois, it began northeast of Thomson inflicting EF0 and EF1 damage to trees and homes. It rapidly intensified to EF3 strength as it moved past Ideal, were a barn was blown off its foundation and trees were debarked. It continued east-northeast maintaining EF2 strength passing through rural areas of Ogle County. The first instance of EF4 damage occurred northwest of Milledgeville, where a farm home was completely disintegrated and blown off its foundation. A tractor from the location was hurled 170 yards.

Southeast of town, it became a high-end EF4, leveling or sweeping away several homes, tossing a car over 200 yards, and debarking and snapping trees. It reached peak strength as it passed through the northern tip of Oregon, where it completely swept away several large, well-anchored homes at borderline-EF5 intensity. Granulated debris was pushed east into debarked trees. On the shore of the Rock River, several houses were flattened, and one was pushed off its foundation into the river. It weakened to EF2 strength and re-entered rural areas. It narrowly missed the town of Holcomb to the south, although one house lost its second story, where an EF3 rating was applied. To the east, ground scouring was noted, and as the tornado crossed I-39 it scoured pavement from the highway. South of Fairdale, where a similar EF4 passed through in April 2015, a house sutained low-end EF3 damage. Low-end EF4 damage occurred in a subdivision west of Kirkland, where several houses were flattened and left as piles of rubble. EF2 to EF3 damage was noted to many homes and businesses on the northern tip of town. It intesified to high-end EF4 intensity again northwest of Kingston, where again numerous homes were flattened or partially swept away. North of Genoa, two homes were destroyed at EF2 strength. No significant structures were damaged for some time after that. An industrial facility lost its roof and an outer wall at EF3 strength as the tornado neared Huntley. A tornado emergency was issued as it moved into heavily populated residential areas of Huntley, where widespread EF4 damage occurred, as several homes were leveled. Cars were thrown long distances and trees were debarked. The tornado gradually began to weaken as it moved east, crossing I-90 and eventually dissipating near Carpentersville. It was on the ground for roughly 3 hours and is considered one of the strongest tornadoes of this outbreak, along with the Albert Lea EF4 on June 9th. There was a dispute over the rating of this tornado, as one survey team found EF5 damage. Due to contextual discrepancies and doubt over certain buildings' structural strength, the EF4 rating was maintained.
