The tornado outbreak of June 8-11, 2020 was a four day severe weather event that produced numerous significant tornadoes across the Upper Midwest. 39 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 (EF4+) tornadoes. Only five days in recorded history since 1950 had more violent tornadoes than June 9th.

Meteorological synopsis

June 8

As a powerful shortwave trough dropped into the northern United States and moved east-southeast, the stage was 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 across the central and eastern portions of the Dakotas, 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 on June 8, including one EF4 in South Dakota.

June 9

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 250-400 m2/s2 range and MLCAPE exceeded 3,000-4,000 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. A PDS tornado watch was issued that afternoon and several long-tracked, intense supercells developed spawning 55 tornadoes, 35 of which were Rated EF2 or higher, including 8 EF4's. The high concentration of significant and long-tracked tornadoes on June 9 is fairly unique for June outbreaks and the region. After dark, storms congealed into an MCS, and several QLCS tornadoes occurred across Wisconsin, many of which were significant; one such tornado was rated EF4.

June 10

By the morning of June 10, the MCS from the previous night had weakened, and rapid destabilization occurred in north Illinois and southern Wisconsin. The surface low had moved southeast, now positioned in northeast Iowa. A moderate risk was issued with a 15% hatched tornado risk across the northern half of Illinois. While isolated supercells were anticipated in that region, the warm front in southern Wisconsin would also be a focal point for tornadic activity on June 10. Modest to good wind shear coupled with excellent instability allowed for 31 tornadoes to form, including two EF4's, one of which having a path length of about 91 miles. A high-end EF2 tornado tracked through western Chicago, as well. Activity became sloppy into the evening hours and another MCS formed, continuing through the night until weakening before dawn on June 11.

June 11

Another moderate risk for tornadoes was issued on June 11, this time for northwest Ohio. An enhanced risk extended into Central Ohio, where a more conditional, but still significant, tornado threat existed. The surface low on this day was located in extreme southwest Michigan, and the whole warm sector was primed for supercells and tornadoes that evening. Again, modest to good wind shear existed across northwest Ohio, northeast Illinois, and southern Michigan, with plentiful summertime instability. 32 tornadoes touched down, including two EF4's. The town of Monroeville, Indiana was hit by two separate tornadoes (an EF4 and an EF3) within an hour. New Albany, Ohio, which was hit by an historic EF5 tornado during the tornado outbreak of April 23, 2020, was hit again in this outbreak by a high-end EF3 tornado at dusk, severely hampering cleanup efforts which were still ongoing. Storms tapered off as the sun set, bringing an end to the outbreak.

It turned a bit more to the north and reached peak intensity on the east side of Browerville. Over a dozen houses were flattened at high-end EF3 strength. 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.

Illinois
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. Nearby, grain bins were toppled and crushed. Ground scouring was noted as well as slight wind-rowing of debris. Similar damage was noted to a home on Eagle Creek, where a home was completely flattened and trees were debarked. Two outbuildings on the property were swept away, as well. On S Summer Hill Road, an old, unanchored house was picked up off its foundation, carried 80 yards, and smashed into the ground, killing a man inside. Southwest of Mt. Morris, it re-intensified to EF4 again, completely debarking trees and sweeping away a large house. 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 the structural integrity of certain buildings, the EF4 rating was maintained.

EF3	New Albany	Franklin, Licking	0050	6.69 mi	Large, high-end EF3 wedge tornado that impacted New Albany, Ohio, including many areas previously impacted by an EF5 tornado on April 23. The tornado began and slowly moved into the Hampstead subdivision in New Albany. There, EF1 and EF2 damage was widespread. At this point the tornado grew to a large wedge and a PDS tornado warning was issued. The tornado intensified as it approached New Albany High School, reaching low-end EF3 strength. The school's gym was most heavily damaged, and significant roof and wall damage occurred. The tornado persisted into the central part of New Albany, where an EF5 had done catastrophic damage less than two months prior. High-end EF3 damage was noted in the Windsor subdivision, as well as to the fire station. A car was tossed about 350 yards to the east in this area. The tornado weakened slightly to low-end EF2 strength inflicting severe damage to Mt. Carmel Hospital, then weakened substantially as it left Franklin County. It lifted roughly twenty minutes after touching down, injuring seven. Due to an early warning, no fatalities occurred. It is a remarkable coincidence that the town of New Albany sustained two direct hits from intense tornadoes in the same year.
