Event narrative: An EF-1 tornado began in northern Somerset County near Bernardsville along the NJ Transit Line just to the southwest of the intersection of Minebrook Rd and Old Quarry Rd. There it dropped numerous trees onto the NJ Transit Line and snapped the trunk of around ten trees. As it moved to the northeast, the storm uprooted two maple trees along Mine Brook behind the Rose Bowl Baseball field that were on a slight embankment. The storm continued to move towards the northeast into Bernardsville where it produced tree damage along Laurel Lane and snapped the trunk of a tree that appeared not to be fully healthy. The tornado then started to move more towards the north following Mine Brook through Bernardsville producing damage from Timber Rock Trail to Anderson Hill Rd where it snapped the trunk of a pine tree that ended up falling on a vehicle. The peak width of the tornado was over this area where the damage path was approximately Four hundred seventy five yards between the damage from Timber Rock Trail to Anderson Hill Rd. Additional damage was found along the path of Anderson Hill Rd moving to the north towards the intersection of Seney Dr and Anderson Hill Rd where numerous trees were brought down with at least two ending up on power lines. At the intersection of Anderson Hill Rd and Rolling Hill Rd, another large tree had its trunk snapped. However, the interior of the tree was determined not to be healthy, so the expected winds based on the DoD were reduced significantly. As the storm was starting to occlude and weaken, it took down several more trees along Old Fort Road including uprooting multiple trees with wide, but shallow root systems. The tornado then dissipated as the storm moved further to the northeast. The EF-1 rating is primarily based on the number of trees with snapped trunks with the highest concentration in a single location being along the NJ transit line. This is where the damage indicator of hardwood trees with degree of damage of trunks snapped produced an expected wind speed of one hundred five mph.
Episode narrative: A vigorous short-wave trough interacted with an approaching low pressure system and associated warm frontal boundary to trigger clusters of strong to severe thunderstorms across west-central Illinois during the late afternoon of August 6th.  Due to enhanced low-level wind shear along and north of the warm front, many of the cells began rotating and spinning up occasional funnel clouds.  One of the cells intensified as it pushed into Sangamon County, producing a long-track tornado that was on the ground for over 25 miles from just north of Pawnee in far southeastern Sangamon County to southeast of Stonington in Christian County.  The tornado produced EF-1 damage along much of its path, peaking with EF-2 damage just south of Willeys in Christian County.  This particular thunderstorm cell dropped 2-inch diameter hail north of Taylorville and went on to produce a downburst with 80 mph wind gusts in far eastern Shelby County near Lake Mattoon.  The storms eventually congealed into a line as they pushed into eastern Illinois later in the evening, with scattered wind damage, hail, and flash flooding.

Event narrative: This is part 1 of the tornado, Part 2  continues into Burt County. The tornado touched down just south of Highway 275, damaging a home, power poles and numerous trees as it entered the Elkhorn River valley. it caused EF-2 damage to a home just south of the Elkhorn River where a porch was ripped off and large trees damaged. The tornado crossed the Elkhorn River where significant tree damage was noted and several center pivots were flipped over. The tornado became wider and impacted additional farmsteads with EF-2 damage, especially as it approached County Road F up to the Dodge and Burt county line. At these farmsteads, several hog barns, machine sheds, and well-built outbuildings were destroyed. Farm equipment was significantly damaged. Windows were broken out of homes, roofs damaged, porches ripped off, and garage doors sucked out. Several people noted that their ears still hurt a day later due to the pressure drop during the tornado. Numerous livestock were injured or killed. The maximum width of this tornado approached one mile as it moved between County Road F and County Road B. A large cattle feedlot was impacted in extreme northeast Dodge county where very large grain bins and well built barns were destroyed. This tornado exhibited multiple vortex damage patterns at times. The tornado appears to have dissipated just north of County Road F in Burt County before developing a new tornado just to the north. Additionally, a satellite tornado was reported near the end of this tornado's life cycle.
