Episode narrative: A tornado outbreak occurred across Central New York during the afternoon and evening hours. Strong shear supported multiple rotating thunderstorms. While damaging wind gusts were a hazard, tornadoes were the main concern. Multiple NWS surveys were performed over a couple of days to confirm a total of five tornadoes. Surveyed damage included downed trees and wires as well as structure damage to multiple residences. Fortunately, no one was injured or killed during these storms.

Episode narrative: A cold front dropped slowly through North Dakota as an upper level low moved across southern Saskatchewan, with severe thunderstorms developing along and ahead of the front. Along one boundary ahead of the front, in the Voltaire area of McHenry County, two short-lived landspout tornadoes formed. No damage was reported with the tornadoes and so by National Weather Service policy the tornadoes were rated EF Unknown. The tornadoes touched down 12 minutes apart from two different thunderstorms. Otherwise, damaging thunderstorm winds were the main threat with most of the storms, though one storm produced one-inch diameter hail near Bottineau in Bottineau County. The strongest wind gust was estimated to be 75 mph, and occurred near Twin Buttes in Dunn County, where a truck window was broken out and a snowmobile trailer was blown down a coulee.

Event narrative: This EF-0 touched down on the far northeast side of Itasca near the intersection of Prospect Ave and Thorndale Ave. It then tracked east-northeastward through a large industrial park in Wood Dale, Bensenville, and Elk Grove Village, where it caused minor damage to the roofs and fascia of a few warehouses and sporadic tree damage, which was most concentrated and severe near the intersection of Lively Blvd. and Kirk St. Eyewitness reports suggest that the tornado may have lifted intermittently along its track before it lifted for good east of Elmhurst Rd. over the far northwest side of Oï¿½ï¿½ï¿½Hare Airport.
Episode narrative: A line of strong to severe thunderstorms raced east-southeast from the Ozarks through the mid South during the evening hours of the 9th and into the Tennessee Valley during the early morning hours of the 10th.  The line produced several reports of wind damage and one EF-0 tornado in Limestone County.

Tornado event in LIMESTONE County, ALABAMA
Start: 10-AUG-23 01:21:00
End: 10-AUG-23 01:28:00
Direct deaths: 0
Event narrative: Damage was consistent with a high-end EF-0 tornado with maximum winds of 85 mph. The tornado was on the ground for approximately 7 minutes and had a maximum width of 225 yards.  Damage indicators were a mix of softwood and hardwood trees, uprooted or partially snapped along the path. The tornado formed on the northern shore of Wheeler Lake on Little Elk Road, downing softwood trees at this location. The tornado crossed Snake Road to the southeast, downing and uprooting additional softwood trees along Bay Hill and Bay Shore Drives. Several homes at this location sustained significant damage to docks as trees fell on them, with uprooted trees causing damage as well to retaining walls and sprinkler systems in this area. At this point, the tornado crossed the open waters along the north shore of Wheeler Lake before coming ashore again just before Davis Road. Several trees were uprooted along with very large, snapped branches here. One home sustained damage in this area as a tree fell on the back side of the structure. While the tree looked snapped, the health of the tree looked to be in question which likely led to its quick failure. The tornado then crossed an inlet and uprooted several more trees along Beechwood Road, before continuing to the Brigadoon neighborhood. Significant and more widespread tree damage was noted in this neighborhood as trees were uprooted, power poles knocked down, and large branches snapped. The tornado continued to follow the northern shore of Wheeler Lake but began weakening. Damage, much less widespread compared to areas further west, was observed along Beech Fork Lane and sporadic tree damage through Shaw Road. The tornado dissipated just east of Shaw Road.
Episode narrative: A highly anomalous pattern for August including an unseasonably intense low pressure system created several hours of severe thunderstorms including the final round of storms that grew upscale into a severe mesoscale convective system.

Event narrative: The tornado started on Yarnell Road, then reached peak intensity and width as it passed the Lovell Crossing apartment complex. Significant roof damage was noted to several of the homes and apartments in Lovell Cove and Crossing, with partial roof loss and uplift of roof decking common to several apartments. In addition to roof damage, a complete collapse of a garage at Lovell Crossing was noted, along with wooden boards driven into the ground and a large gash in the side of apartment complex office from the impact of a large, but unknown object. Numerous trees in the apartment complex suffered damage from the tornado. The tornado then crossed Pellissippi Parkway, and continued along and north of Bob Gray Road. A driver on Pellissippi Parkway recorded a video of the tornado crossing the parkway. Significant tree damage was observed along Bob Gray Road, with a narrow path of snapped hardwood trees as the tornado progressed eastward. The tornado appears to have dissipated at the intersection of Bob Gray Road and Middlebrook Pike.
Episode narrative: Scattered severe t-storms during the afternoon on July 22nd produced a brief small land spout type tornado and numerous large hail reports.

Event narrative: Video of a small brief land spout type tornado was provided.  The eyewitness said the feature lasted around one minute as best they could tell. No known damage.
Episode narrative: During the early morning hours of May 7th, a cluster of strong and occasionally severe thunderstorms over central Illinois gradually grew upscale into a bowing line of storms as it moved southeast into central and southern Indiana toward dawn. Ahead of the developing quasi-linear convective system, a moderately unstable environment was present across southern Indiana, with MLCAPE ranging from around 500 J/kg in the east to around 1500 J/kg in the west. The line of thunderstorms generally produced sub-severe wind gusts across southern Indiana, as the strongest winds remained aloft thanks to a residual nocturnal stable layer. However, as storms approached the Ohio River, a few discrete cells moving from west to east were overtaken by the line which was moving from north-northwest to south-southeast. In the fifteen minutes or so after these cell mergers took place, five brief spin-up tornadoes occurred in Floyd County, producing pockets of structural and tree damage across the county. All of the tornadoes produced either EF0 or EF1 damage, with estimated wind speeds generally between 75 and 105 mph. Minor straight-line wind damage was also observed as this line of storms moved through. The severe threat ended by 10 a.m. as storms pushed southward into central Kentucky.

Event narrative: At 3424 Hamby Road, several trees were snapped and uprooted. Trees were facing from the east northeast to a southeasterly direction. Branches from the trees were scattered from the northeast to the southeast direction. An outbuilding had some siding and gutter damage. Of particular note was a large, healthy red oak tree that was uprooted with a significant root ball, which hit the far corner of the neighbor's house, doing structural damage to the roof and gutters.       The vast majority of the damage was to the trees, and just off the ground. The tornado topped a few trees at the edge of their property by the forested area, before lifting. Wind speeds of 90 mph were estimated, with a width of 100 yards, across this very short tornado track.
Episode narrative: An upper level low pressure system slowly ejected northeast across the piney woods of East Texas during the evening through the morning hours of May 10th-11th. A southerly low level jet present ahead of the low spilled copious amounts of low level moisture north into East Texas and Western Louisiana, with strong large scale forcing ahead of the low enhancing numerous shower and thunderstorm development which moved repeatedly over these areas throughout much of the overnight into the early morning hours. Widespread rainfall amounts of 2-4+ inches fell across much of North Louisiana during the morning through the early afternoon hours on the 11th, resulting in instances of flash flooding across this area. Given the strong low level wind shear out ahead of the low, as well as increased instability especially with the onset of daytime heating, severe thunderstorms containing damaging winds, while also spawning a few isolated tornadoes, were observed throughout the morning as well before eventually diminishing during the afternoon.

Event narrative: A weak EF-1 tornado with estimated maximum winds near 88 mph, touched down near the intersection of Cedar Creek Drive and Dean Road, before moving northeast across Highway 3132, St. Helens Drive, Hickory Ridge Road, Meriwether Road, Parkdale Drive, Walker Road, before lifting along West 70th Street on the southeast side of the Shreveport Regional Airport. Most of the damage was limited to tree limb damage and tree uproots, although a few structures were damaged by falling limbs. The most highly rated damage occurred between Meriwether Road and Parkdale Drive, where a handful of snapped softwood trees warranted a peak wind speed of 88 mph. A tornadic debris signature for the Shreveport dopplar radar was coincident with the majority of the tornado's track.
Episode narrative: A deepening upper/low pressure system slowly approached portions of the Central Plains on the 11th. Combined with increasing instability and wind shear, a favorable environment for severe weather (capable of producing all severe hazards) developed across much of western into central Oklahoma on the evening of the 11th. Numerous supercell thunderstorms developed and produced twelve tornadoes and large hail across portions of these areas.

Event narrative: The tornado first touched down on the northwest portion of the Brookside subdivision (near the eastern portion of Georgetown Lake), with a couple larger branches of two older compromised trees twisted off. The Brookside subdivision is located just south of Indiana Route 64 and just east of Baylor Wissman Rd. There were over a dozen homes sustaining shingle, soffit, gutter, and fascia damage with many tarps on roofs. Shingles were thrown from an east northeasterly direction to a east southeasterly direction. There was little if any tree damage inside the subdivision, with one playground lifted and thrown into a fence. Drone photography showed the vast majority of the damage was to shingles and to soffits. The damage was estimated to be EF0 with 80 mph winds. The last damage point was in a wooded area just east of Zachary Trail before interstate 64. One tree was topped in that grove of trees.

Event narrative: A EF-1 tornado with estimated maximum winds near 100 mph, briefly touched down along the west and east sides of Highway 763 a couple miles south of Stanley. Along its brief path, several softwood trees were snapped but multiple hardwood and softwood trees were uprooted. An outbuilding and a single family home on the west side of the road sustained roof damage by wind impacts alone. There was also minor wind damage to a single-wide mobile home on the east side of the road. A tornadic debris signature  from the Shreveport dopplar radar was observed with the surveyed damage, but also continued about a mile farther east. This suggests that the tornado probably continued on farther east for some distance after the end of the surveyed track, although the NWS survey team had no ground access to survey points immediately to the east.

Episode narrative: On the afternoon of May 6 strong thunderstorms formed in far northwest Missouri. Through the afternoon these storms strengthened as they moved east across northern Missouri, ultimately turning into robust supercells that started diving southeast toward Highway 36. Along the way they produced giant hail reaching, and perhaps exceeding 4 inches at times. As the main storm pushed southeast toward Linneus, Missouri it produced a tornado that at times was several hundred yards wide. This tornado produced EF-2 damage just north of Linneus. Perhaps as noteworthy, if not more so, was the extremely strong and wide rear flank downdraft that produced some intense damage well south of the main tornado track. This RFD destroyed numerous homes along the way and produced extreme tree damage to the city of Linneus, which was largely spared a direct hit from the actual tornado. Overall the storm produced three separate tornadoes, the most noteworthy of which was the EF-2 just north of Linneus, Missouri.

Event narrative: After the large tornado across central Linn County there was a brief interruption in the damage path. The next tornado formed a few miles southeast of where the larger tornado circulation became discontinuous. This tornado did some minor damage to residences and outbuildings between Linneus and Bucklin. Some of the more extensive damage occurred from rear-flank downdraft winds 1-2 miles south of the main tornado circulation.
Episode narrative: Thunderstorms developed along a cold front brought severe weather to central South Dakota during the evening hours. A storm moved into Pierre and Fort Pierre, SD, producing hail. There were numerous reports of baseball-sized hail across the area, and even one larger than a softball, with an estimated diameter of 5.0 inches. The hailstone is the largest on record in Hughes County (4.0 in Pierre on 6/30/1997 and Blunt on 8/26/2018). Damage was done to vehicles, roofs, and other outside structures. The storm also produced a brief tornado about 11 miles south of Fort Pierre, just west of US Highway 83, around 6:45 pm CDT. These storms then moved south and east through the evening, producing large hail and damaging winds. A wind gust of 100 mph was recorded just west of Oacoma at 8:15 pm CDT via a weather station from the South Dakota State University's mesonet. Damage was done to power poles, trees, trailers, and other property in and around Oacoma.
