Event narrative: This tornado developed in an open field and caused no known damage. It was documented by a few storm spotters in the area.
Episode narrative: A strong, occluding storm system over the Upper Midwest produced a deep column of strong southwesterly winds over the Midwest on the afternoon and evening of the 31st. This pattern generated an inordinate amount of vertical wind shear.  The overall southwesterly flow also brought rather mild and somewhat humid air into the region, which was adequately unstable given noticeably colder air aloft, especially over the southwestern quadrant of Indiana.

Resulting thunderstorms were able to mix down the stronger winds to the surface as damaging straight line gusts, while a rather low freezing level promoted isolated large hail.  Ten tornadoes occurred across the region:  5 from a rotating supercell thunderstorm that tracked roughly parallel to and about 20 miles south of Interstate 70, and 5 others spawned from a squall line's northern book-end vortex that impacted north-central central Indiana.  The supercell's first two tornadoes (both EF3) caused a combined 5 fatalities...before the supercell spawned two more strong tornadoes (EF2/EF3), with the cell's final EF3 inflicting major damage on a warehouse in Whiteland (Johnson Co.).  The (northern) squall line's first tornado was an EF2 that impacted mostly rural areas...while the squall line's four following tornadoes were all weak (EF0/EF1), with the final three spawned over Howard County, concluding with a longer tracking EF1 that injured one person.

Event narrative: This secondary and weaker squall line tornado began just west of the Montgomery-Boone County line (tracking just southeast of the nearby, multi-county EF2 tornado).  A barn just inside Montgomery County was partially destroyed by 85 mph winds with debris thrown into Boone County and blown one-quarter of a mile to the northeast.  The tornado also downed utility poles along the county line road before continuing into Boone County.
Episode narrative: Numerous strong to severe thunderstorms developed during the late afternoon of June 15th, mainly south of I-96. Hail, measuring between 1-2 inches, emerged as the primary severe weather threat, with several instances of wind damage associated with gusts around 60 mph. The large hail caused extensive crop damage across Livingston county. Notably, an EF1 tornado also developed just west of Lake Erie. This tornado, which remained on the ground for 9 minutes, exhibited a maximum wind gust of 90 mph. In its wake, damage was reported which included multiple large fallen limbs and trees, along with damage to several residential properties.

Event narrative: A 130MPH EF2  tornado touched down near the confluence of the Pascagoula River and Escatawpa River at 2:48 PM CDT and moved southeast across the River and into the neighborhood on Griffin Street. Widespread tree branches were downed, along with some uprooted trees. Several homes had minor to moderate damage to siding and roofing. A fifth wheel RV was turned over on its side. At 2:54 PM CDT the tornado moved southeast towards Dantzler St. The damage was sporadic as it moved but one house on Bellview Ave took major roof damage, the carport collapsed and a motorhome parked nearby was overturned. It continued east-southeast over wetlands towards Main Street then sharply turned to the south-southeast. The tornado moved south along Main Street between Bellview Ave through E Bayou Ave. Numerous structures took roof damage with the most significant damage seen at the Merchants & Marines Bank and the First Missionary Baptist Church. Both buildings had the majority of the roof removed and several windows blown out. The Church's brick signage was completely destroyed. Several nearby older houses also received significant roof damage. This damage was the peak of this tornado with max winds of 130 mph and max width of 300 yards. The tornado continued southeastward towards Martin Luther King Blvd. The damage was sporadic with mainly trees downed and minor roof damage. The tornado then moved towards the intersection of Jackson St and McCall St where a small multi family home had its roof damaged. Due to the age and the type of construction, the south facing wall collapsed due to the roof damage. The tornado then continued east-southeastward and lifted before it reached Frederick Street at 2:57 PM CDT. Special thanks to the Jackson County Office of Emergency Services for their assistance in the survey including drone footage.
Episode narrative: During the afternoon and evening of June 15th, an upper-level disturbance triggered a cluster of thunderstorms along a stationary front boundary around the Texas and Oklahoma border. These storms intensified and grew upscale into an intense mesoscale convective system (MCS) as they moved east-southeast along an axis of increased moisture and strong instability that extended toward the Central Gulf Coast. As the MCS moved into western Mississippi with a bow and arrow structure, it exhibited an unusually intense rear-inflow jet with velocities as high as 80 to 100 mph descending to around 1,000 feet above the ground, as viewed by the KDGX NEXRAD site. A wide swath of significant severe wind gusts at the surface caused widespread wind damage including snapped and uprooted trees, downed tree limbs and power lines, and damage to homes and other structures. Surveys of the wind damage indicated that peak wind gusts of 90 to 100 mph likely occurred in the most intense portions of the line. Over 240,000 power outages resulted in portions of the area and many continued for several days following these and other storms that occurred during the middle of June. Two embedded EF-1 tornadoes occurred with the squall line.  There was one fatality in Madison County due to the straight line winds, and several other injuries were due to fallen trees across the state. Later in the evening, additional severe thunderstorms produced hail up to the size of grapefruits and caused scattered wind damage.
