1.) Osage Township Tornado
|
(click on image to enlarge) |
|
Summary: This tornado started in the vicinity of N 8th Road near Sandy Creek. Distinct swirl marks are evident as the tornado tracked northeast before tracking almost due east and crossing E 9th Road roughly one third of a mile south of IL-17. The tornado then continued on a northeasterly path, impacting a residence on IL-17 where it caused some roof damage, snapped a large hardwood tree about one-third of the way from the top, and downed a wooden electrical pole. The tornado then continued along IL-17, destroying multiple machine sheds in the 900 block, with debris strewn northeastward toward E 10th Rd. Storm chaser video shows at least three fast-moving subvortices as the tornado continued northeast and crossed E 10th Rd. Here, high-resolution Sentinel satellite imagery reveals significant cycloidal markings, widening to approximately 500 yards as the tornado tracked across multiple fields before appearing to weaken rapidly and lift near N 10th Rd just west of the Livingston County line. |
2.) Long Point - Streator Tornado
|
(click on image to enlarge) |
|
Summary: This tornado began in a field southwest of E 2600 N Road and N 190 East Road. It tracked into Long Point, where some tree damage was noted before continuing northeast with sporadic damage near Ancona and Reading Township. The tornado intensified as it crossed east of N 500 East Road, where it blew a grain bin off its foundation and dragged it along the ground for approximately 700 yards. The tornado reached its peak intensity on the southeast side of Streator near the Livingston-La Salle county line. Here, several houses along Sunbury Drive were heavily damaged. At one residence, only the inner-most walls were left standing, with debris tossed southward, upstream against the tornado path. Damage in this area was consistent with EF-3 winds around 145 mph. The tornado continued northeast before turning nearly due north, causing damage consistent with EF-2 caliber winds to several residences along E 19th Road. The tornado appears to have lifted northeast of Streator near N 1475th Road. |
3.) Rowe - Dwight Tornado
|
(click on image to enlarge) |
|
Summary: The tornado appeared to start near IL Route 23 just north of Rowe before tracking northeastward across portions of central Livingston County. The tornado may not have been fully condensed to the ground or consisted of intermittent touchdowns along the first half of its path, where damage was primarily confined to trees. Based on storm chaser videos, the tornado appeared to rapidly strengthen and widen northeast of Odell while crossing IL Route 47 and approaching the unincorporated community of Blair, where several homesteads sustained roof and siding damage and several barns were destroyed. Storm chaser video depicted subvortices within the tornado as it crossed several open fields in the general area. The tornado then appeared to lift just north of IL Route 17. The tornado was likely stronger than the official rating of EF-1, though a lack of impacted damage indicators precludes a higher rating. |
4.) Blackstone Tornado #1
|
(click on image to enlarge) |
|
Summary: Several storm chaser videos confirm a brief tornado began in a field between N 975 East and N 1100 East roads. Videos clearly show this tornado crossed E 3200 North Road and dissipated in a field just south of the LaSalle-Livingston county line. No known damage is associated with this tornado, leading to an EF-U designation. |
5.) Blackstone Tornado #2
|
(click on image to enlarge) |
|
Summary: At least two storm chaser videos show this brief tornado touch down east of Illinois Route 18/North 1200 E Road just north of the LaSalle-Livingston county line near a wind farm. No known damage is associated with this tornado, leading to an EF-U designation. |

Summary: Eyewitness reports and radar data indicate that a tornado began in Pratt's Wayne Woods before quickly intensifying and tracking east-northeastward into Bartlett. The tornado produced a concentrated area of EF-1 damage at a shopping center at the intersection of Sutton Road and Stearns Road, where roofing material was peeled off of buildings, brick columns and metal fencing were blown out at a garden center, and all of the gas pumps at a gas station were blown over. The tornado continued to produce extensive tree damage at Beaver Pond Park and in the subdivisions to the east of the shopping center before dissipating east of Bartlett Road. |
19.) Morocco Tornado
|
(click on image to enlarge) |
|
Summary: This tornado touched down near S 600 W Road just north of the intersection of W 550 S Road before tracking northeast across mainly open farmland in western Newton County. The tornado damaged a farm outbuilding along with several trees near S 550 W Road consistent with 85 mph winds and an EF-0 rating. From there, the tornado continued northeast through the town of Morocco, where a corridor of tree damage occurred, including near the town park. Additional tree damage across the broader Morocco area was consistent with straight-line winds in excess of 60 mph. After exiting Morocco, the tornado crossed US-41 before turning to the north-northeast across open farmland, where damage was confined to mainly trees and irrigation pivots. The tornado ended just east of the intersection of E 300 N Road and N 300 E Road. No injuries or fatalities were reported with this tornado. |

21.) Boswell - Atkinson Tornado
|
(click on image to enlarge) |
|
Summary: This tornado began approximately one and half miles southwest of Boswell, initially damaging an outbuilding and peeling a few roof shingles off of a house at a farmstead on S 400 W Road. The tornado tracked east-northeastward and blew down a barn and power lines along S 200 W Road before curving off more towards the northeast. It then blew a press box off of the bleachers at Daugherty Speedway and into a nearby power pole and field before reaching peak intensity as it tracked into the unincorporated community of Chase. There, a grain elevator and multiple associated grain bins were destroyed, and a couple of tree trunks were snapped. The tornado then continued to the east-northeast, snapping multiple rows of power poles from Meridian Road to S 200 E Road and downing another set of power poles in the unincorporated community of Atkinson. As the tornado reached E 200 S and S 600 E roads, it downed more power poles; downed a few trees; damaged the roof, chimney, and gutter of a house; and blew a chicken coop into a field, killing 30 chickens. The tornado likely dissipated shortly after crossing S 600 E Road. |

Meteorology and Environment
Tornado outbreaks are rare and require an overlap of strong instability and strong wind shear. Provided both ingredients are in place, there are additional contingencies on the types of storms that develop (supercells, squall line?), number of storms (just a few or so many that they destructively interact?), direction of travel (will they remain in the favorable environment for long?), and time of day (will the storms begin to weaken after the sun sets?). And, that's not taking into account other subtle factors such as the impact of earlier rounds of showers and thunderstorms. Needless to say, a lot has to go wrong to support a tornado outbreak.
In the Lower Great Lakes region, tornado outbreaks often occur when a low pressure system intensifies while tracking from central Iowa into Wisconsin. In such scenarios, a warm front often lifts across the region, serving as a focus for both wind shear and thunderstorms. On June 11, 2026, such a meteorological set-up was forecasted to occur with a low pressure system expected to strengthen while lifting from northern Missouri toward central Wisconsin. A warm front was expected to lift across northern Illinois and into southern Wisconsin, potentially serving as a focus for tornadic thunderstorms. Taken together, there was higher than average confidence in an episode of severe weather across the region on June 11.
No forecast is clear-cut, and the regime on June 11 was no different. While the overarching weather pattern would be supportive for severe weather, there was a giant fly in the ointment whereby early-day thunderstorms were expected to impact the position of the warm front. Oftentimes, early-day thunderstorms suppress the northward movement of such frontal boundaries, leading to uncertainty as to whether the best instability (located near and south of the front) would overlap with the strongest wind shear (closer to the center of the low pressure system). While forecast models suggested the warm front would lift as far north as southern Wisconsin, the early-day thunderstorms caused the front to orient from northwest to southeast across north-central Illinois and northern Indiana.
| Storm Prediction Center Outlook | Description |
 |
Five Days Beforehand:
On June 7, five days before the eventual tornado outbreak, forecasters at the Storm Prediction Center highlighted the Lower Great Lakes as a region favorable for severe weather. The yellow-shaded area corresponds to the equivalent of a Level 2 out of 5 threat level for severe weather. |
 |
Four Days Beforehand: By June 8, four days before the outbreak, parts of the area were upgraded to the equivalent of a Level 3 out of 5 for severe weather. Such a level is relatively rare anywhere across the country four days in advance, let alone in the Great Lakes region. Included in the associated forecast discussion was a prescient statement noting a threat for tornadoes: "There is some model signal that a corridor of enhanced tornado potential could develop along and south of the surface low track from eastern IA into northern IL into central and southern WI." |
 |
Three Days Beforehand: Three days before the event, the big-picture items started to become more in focus. At this point, there was an emerging signal that there could be two windows of storms on June 11 with an early-day line of storms and an afternoon round of supercells. Forecasters at NWS Chicago noted in an Area Forecast Discussion: "Do want to highlight that there is a scenario where morning thunderstorms reinforce a west-to-east orientation of the warm front by late afternoon somewhere in our area. (...) The net result would likely be the development of a focused zoned of intense thunderstorms with a threat for all hazards (tornadoes, destructive winds, damaging hail, and flash flooding) in our area." |
 |
Two Days Beforehand: The day before the event, concern continued to rise for a regional severe weather outbreak. The Storm Prediction Center broadened the areal extent of the Level 3 out of 5 threat level area. In addition, forecasters at NWS Chicago remained focused on the apparently growing threat for tornadoes. In an Area Forecast Discussion, it was noted: "Of particular concern is the rapid increase in low-level flow on the southeastern flank of the surface low during the evening hours. (...) Accordingly, should supercell storm modes be maintained along the warm front, there will be a threat for strong (EF-2+) tornadoes." |
 |
The Day Of: The day of the tornado outbreak, the Storm Prediction Center issued a rare level 4 out of 5 threat level area across northern Illinois driven by a threat for tornadoes. In addition, forecasters at NWS Chicago noted great concern for tornadoes, noting in an Area Forecast Discussion:
"Am quite concerned in a relatively narrow west-to-east zone favorable for strong to intense tornadoes (EF-3+) somewhere across southern Wisconsin and northern Illinois particularly between 4 and 8 PM. (...) Pinpointing the eventual location of the warm front will be paramount to identifying the zone of greatest tornado potential (...)" |

Individual Meteorological Variables:
 |
 |
 |
| Surface pressure analysis at 6 PM showing a seasonably deep area of low pressure around 1000 mb shifting across southern Wisconsin. | Temperature and dewpoint analysis at 6 PM. Strong south to southeasterly winds were helping push increased moisture northward following widespread morning rain and thunderstorms. | Accompanying surface observations at 6 PM. Temperatures jumped around 7-11 degrees in 1-2 hours, and dewpoints additionally surged back into the upper 70s. |
 |
 |
 |
| Winds around 20,000 feet at 6 PM were near 50 knots and steadily increasing with the approach of a robust upper-level disturbance. | Winds around 5,000 feet. These were rapidly increasing, to around 45-50 knots. This rapid increase promoted a considerable uptick in low-level wind shear. | 0-1 km wind shear analysis around 6 PM. Values were increasing through 30-35 knots, which is exceptionally strong and supportive of low-level storm rotation. |
 |
 |
 |
| Significant Tornado Parameter analysis at 6 PM. Values in excess of 5 highlight a volatile environment supportive of general updraft rotation and tornado development. | Violent Tornado Parameter analysis at 6 PM. Values over 8-10 highlight that the parameter space was rapidly becoming supportive of significant tornadoes. | A special 21Z (4 PM) upper air sounding from Lincoln, Illinois showing a highly favorable thermodynamic and kinematic environment for severe, rotating thunderstorms. |
