Event narrative: A tornado developed and produced a Tornadic Debris Signature (TDS) on the KVNX radar north of Burlington. The tornado moved primarily over cropland, although it did apparently damage a few trees.
Episode narrative: An area of low pressure tracking northeastward across Iowa pushed a cold front into central Illinois during the afternoon of January 3rd.  The arimass ahead of the front became moderately unstable thanks to surface temperatures climbing into the lower to middle 60s and dewpoints hovering near 60 degrees.  Given the instability and increasing amounts of deep-layer wind shear in association with a strong upper low approaching from the west, scattered supercell thunderstorms developed along the front during the afternoon.  The storms were primarily focused in a corridor from Springfield and Taylorville northeastward to near Champaign.  A total of 8 short-lived weak tornadoes touched down within this corridor, with the strongest tornadoes producing EF-1 damage near Maroa and in the Decatur area.

Episode narrative: A widespread significant damaging wind storm tracked across nearly all of eastern Nebraska and western Iowa on the morning of July 12. These storms produced widespread winds of 60 to 80 mph, with embedded stronger downbursts with wind speeds up to 100 mph. The strongest measured wind gust was 82 mph in Dodge County NE, but some of the high-end straight line wind damage supports embedded wind speeds up to 100 mph.

This storm also produced a few embedded tornadoes. Some of the tornado tracks were only identified by narrow swaths of damage through mature cornfields, with minimal damage otherwise and peak wind speeds similar to the nearby downburst winds. All but one of the tornadoes was preceded by a Wireless Emergency Alert. There were 0 reported injuries or fatalities.

Episode narrative: A line of strong thunderstorms moved into north and central Georgia during the afternoon through the evening on Thursday, January 12th and spawned numerous tornadoes, including several that were long track and significant. Ahead of this line, a few supercells also spawned tornadoes in portions of central and eastern Georgia.  Upon further examination of radar data and high resolution areal imagery, it was found that several tornadoes rotated around and within a larger vortex and caused the widespread damage in the area near Griffin GA, over 2 miles wide in some cases.   The result was that as many as 4 tornadoes were on the ground simultaneously in SW Spalding County, which were rotating around the larger circulation, merging together in several cases and crossing paths. The presence of 3 mergers was identified in the reanalysis. Additional analysis revealed that wind speeds in the EF3 storm reached as high as 155mph or high end EF3.  This confirmed a total of 14 tornadoes, including 10 which resulted from the same storm/larger mesocyclone.

Event narrative: This long-track tornado originated in Chambers County, Alabama. The entire survey was conducted by NWS Birmingham. Estimated start point was near County Road 114 west of Highway 431 to the southwest of Five Points. Northeast of Five Points, the tornado intensified, snapping and uprooting many trees along County Road 267 and causing roof damage to a barn. The swath of timber damage became almost a mile wide along County Roads 281 and 282 and at least one residence there suffered roof damage. The tornado continued to intensify as it crossed County Road 268 where large swaths of pine trees were snapped. A manufactured home was completely destroyed and blown downstream near County Road 278. Most of the structural damage happened along County Road 284. A couple residences suffered significant shingle damage, one had siding damage, and a manufactured home had its porch ripped off, impacting its walls. Another manufactured building was blown off its footings. Another significant swath of snapped pines was observed on County Road 283, some snapped off only a couple feet off the ground. The tornado then crossed into Georgia, continuing to snap trees along West Point Lake. Numerous trees were snapped along the end of North State Line Rd.as the tornado crossed the lake. The tornado began to weaken some as it made its way into Deer Point Rd and Rock Mills Road where tree damage and some damage to shingles and gutters occurred for a few homes. The tornado continued east through mostly wooded areas, doing damage to pines and crossing just north of a few homes along Neely Rd. Weakening continued as it continued NE with only minor tree damage occurring before the tornado dissipated along Cameron Mill Rd.

Event narrative: The tornado touched down in the Woodhaven Lakes campground south of Amboy. There, multiple campers were damaged by the tornado including two that were rolled. Farther along its northeastward track, two trees had fallen onto a home destroying it. The tornado appeared to have reached its maximum intensity with wind speeds estimated at 115 mph shortly after crossing US Hwy 52 where it destroyed a large garage and snapped several trees at their trunks. Several dozen other large trees were snapped and many branches sheared off along its path. Toward the end of its lifespan, the tornado also did minor damage to an outbuilding before lifting near Butler Hill Rd north of West Brooklyn.

Event narrative: New high resolution areal imagery in concert with a reanalysis of radar data, areal surveys and ground surveys it has been determined that there were multiple tornadoes on the ground simultaneously in southwest Spalding and Northwestern Pike Counties as well as crossing tornado paths. The tornadoes were part of a larger mesocyclone which can be traced west all the way back to the Selma Alabama tornado. Our analysis determined that this tornado spun up near the center of the main mesocylone as it crossed the Flint River in SW Spalding County. The first evidence of a tornado touching down appear along Blanton Mill Road where several trees were uprooted. This tornado would become caught within the larger circulation and swing SE around the center through mostly wooded or swampy areas of SW Spalding County. Numerous trees were snapped or uprooted in a path that that tracks ESE until it reaches Scott Barch Road. It is in this area it crosses the path of a tornado which passes approximately 2 minutes early moving NE on the eastern periphery of the larger mesocyclone. Low end EF1 damage occurred to a barn in this area, however, it could have occurred with the first tornado. Numerous trees are uprooted or snapped in this area as well. The tornado continued ESE crossing Flat Creek causing mid range EF1 damage to trees. It is noted per areal imagery and radar data that as the tornado approached Yarborough Rd and Shackleford Road it become absorbed/merged with a larger stronger circulation/tornado moving to the NE. Damage on the ground in this area is indicative of tornadoes coming in from 2 different directions. The particular circulation is terminated at this point as the larger more dominate tornado continues NE toward a rock quarry along Rover Zetalla Road. It should also be noted that EF2 damage occurred shortly after these 2 tornadoes merged near Yarborough Road but will be attributed to the more dominate circulation.
Episode narrative: Widespread showers and storms moved through the region on August 13th. One storm became severe and produced a brief tornado in far southern portion of Monroe County Illinois.

Event narrative: A brief, weak tornado formed near Ames Road, just north of intersection with Faust Road and tracked due east. It struck a shed, producing EF0 damage. Images show the debris from the shed was thrown into the pond down wind. Further east, photos show a narrow track through a soybean field north of Faust Road where it dissipated. Overall, the tornado was rated EF0 with a path length of 0.38 miles. The max path width was 10 yards. No deaths or injuries were reported.
Episode narrative: A strong upper level trough ejected over the Southern Plains which caused rapid surface cyclogenesis to occur in southeast Texas. This surface low traversed across central and northern Louisiana. The rapid development of the surface low gave way to very high shear values, and with enough instability, a line of thunderstorms formed along its cold front. A couple of brief tornadoes occurred with the line in Pointe Coupee and Terrebonne Parishes. The Pointe Coupee Parish tornado resulted in 3 injuries. Otherwise, damaging wind gusts were noted with the line due to the extreme shear. The line exited southeast Louisiana in the early morning hours of the 25th.

Event narrative: NWS storm survey found the path of an EFO tornado that  apparently developed over Lake Norman before moving  onshore at the Lake Campus of Davidson College. Picnic tables were blown into the water and a large hardwood tree was snapped. Numerous spots along the shore between the Lake Campus and I-77 saw snapped tree trunks or large branches. One large poplar tree was uprooted and damaged other large trees as it fell. One fence was damaged along with a wellhead. The tornado crossed I-77 at about 7:30 am, and more sporadic damage subsequently occurred across the south sides of Mount Mourne and Mooresville. Numerous large, healthy tree branches were downed between Langtree Rd and Blackwelder Farm Dr. In the vicinity of Mooresville Middle School, a fence collapsed and a tree was uprooted. Uprooted trees and branch damaged occurred in a few spots between Linwood Rd and Teeter Rd. The tornado ended along Teeter Rd just short of the Rowan County line.
