Episode narrative: A surface low moved across north-Florida during the early morning hours as a warm front lifted up from central FL. Strong effective shear combined with marginal surface-based instability near the lifting warm front and surface low enabled rotating mini-supercells to form. Toward sunrise, enough low-level instability nosed inland from the Atlantic coast across Flagler County to support a couple of tornado touchdowns. Locally heavy rainfall occurred across northeast Florida, generally south of the I-10 corridor and toward the Atlantic coast.

Event narrative: A weak, sporadic tornado caused intermittent tree and minor structure damage as it track NE across the east-central part of the county. Tree damage was first reported near the intersection of County Roads 302 and 75 where several pines were snapped. Damage continued along a narrow ENE track which included a flagpole blown down in the R-section of Palm Coast at near the intersection of Rymshaw Drive and Ryman Lane. The last damage report was in Painters Hill where a resident reported a wind sail was shredded and patio furniture lofted and blown away.
Episode narrative: The middle part of June was unusually stormy across the area. Numerous rounds of strong to severe storms impacted the region with multiple squall lines that produced severe winds as well as supercells that produced large hail and tornadoes.  Heavy rain also occurred over a multi-day period, which saturated the ground and led to some instances of flash flooding.  

The synoptic pattern featured well above average 250 mb zonal wind anomalies, which were traceable back to an active subtropical jet stream.  Greater than average instability was also present, in part due to anomalously warm Gulf of Mexico SSTs.  This combination of above average shear from the active subtropical jet and above average instability from the warmer than average SSTs provided a synoptic environment favorable for severe weather as upper level shortwaves moving through the area.  This pattern persisted for many days, leading to an unusually large amount of severe weather.

Event narrative: A pair of tornadoes touched down east of Cuthbert near Trinity Church Road. This tornado was the northern circulation, which touched down near the intersection of Trinity Church Road and Wilton Rigsby Road, causing tree damage and damage to an old out building. Further east, roof damage to a single family home and significant tree damage was noted supportive of an EF-1 rating with winds of approximately 110 mph. The tornado continued east, damaging a church, a mobile home, several stands of trees, and tossing debris into nearby fields. This circulation appears to have dissipated in a field near the intersection of Trinity Church Road and Wooten Road.
Episode narrative: A prolonged, active weather pattern persisted across Georgia through late March, culminating in a series of disturbances that impacted the region March 25th through March 28th. In addition to numerous reports of damaging winds, hail and a few tornadoes, extreme rainfall amounts caused flash flooding over portions of the state. A swath of 4 or more inches of rain stretched from LaGrange, to Forsyth, to Augusta, with isolated amounts above 10 inches.

Event narrative: The tornado first touched down along Ogletree Road where several trees were snapped and uprooted.  The tornado continued east along and just north of Ogletree Road where trees were both snapped and uprooted both along the road and in the forested area to the north of the road.  The tornado increased in intensity to EF1 as it crossed Old Durand Rd snapping and uprooting hundreds of trees.  A large home suffered minor roof damage as the tornado crossed Bobwhite Road.  Numerous trees were snapped and uprooted near the intersection of Ogletree Road and Bobwhite road.  The tornado continued east crossing Hwy 18 at the intersection of Ogletree.  Several homes were severely damaged from fallen trees including a mobile home that was nearly destroyed by a tree.  The tornado weakened as it crossed Hwy 27 and Harmony Church road causing mostly EF0 tree damage as it passed.  The tornado passed Temple Dukes road snapping and uprooting trees causing minor home damage before reaching Dukes Waddell and Moreland Gill road where a large cover attached to a home was destroyed causing damage to the home.  An outbuilding nearby also sustained roof damage in addition to snapping and uprooting trees.   The tornado lifted as it crossed Hwy 85 where a couple trees were uprooted.
Episode narrative: Two areas of thunderstorms brought severe weather to central and northeast South Dakota on the evening of July 25th. A warm front across northeastern South Dakota provided the focus for storms that generated at least one observed wind gust of 63 mph. A secondary area of thunderstorms developed over central South Dakota near a surface low-pressure system. The thunderstorms that developed over Hand County resulted in quarter-size hail, winds in excess of 60 mph, and a brief tornado that produced EF0 damage.

Event narrative: National Weather Service meteorologists surveyed damage in northeast Fayette County and determined that it was consistent with an EF0 tornado, with maximum winds near 80 mph. The tornado touched down just west of County Road 77 with minimal tree damage. Several tree limbs were downed and a couple of trees were uprooted across a pasture as well. Along County Road 101 at Piney Grove Road, a few trees and tree limbs were downed, with a small tree falling on a small detached carport, knocking it down. Several trees were uprooted around a house on Piney Grove Road, and numerous trees were uprooted in an inaccessible area between Piney Grove and Avery Gray Road. Along Heartline Road, a couple of trees were uprooted and some roofing was peeled up on an older manufactured home. At Rocky Hill Drive, numerous small tree limbs were scattered throughout a field and a large limb was broken out of a pine tree. A small pine tree was uprooted along County Road 67 as the tornado lifted.
Episode narrative: A cold front sank south across Iowa during the afternoon and evening of July 28th. The environment was primed for severe storms with warm moist air in place; as temperatures climbed into the 90s and dewpoints into the 70s. By afternoon MLCAPE values of 3000 J/kg were in place across much of Iowa with deep layer shear exceeding 40 kts. Such an environment supported rapid storm development along the boundary by late afternoon. Storms produced ping-pong ball to baseball sized hail along with two tornadoes, damaging confinement pens and creating easily identifiable tracks on high resolution satellite imagery through surrounding fields. As storms pushed south into the evening, the hazards transitioned to a wind threat. A micro burst occurred in Marshall County very near the ASOS, resulting in an isolated pocket of 80 to 90 mph winds.

Event narrative: This was a rather slow moving tornado which moved east initially through open cropland.  The tornado then turned southeast, east and eventually northeast as it journeyed through the farmland.  The tornado did hit a hog confinement with the roof collapsing producing EF1 damage.
Episode narrative: The most notable storm of the day was an intense, long-lived, cyclic tornadic supercell which significantly impacted Scotts Bluff and Morrill Counties during the early evening hours. This storm originated in the central Laramie Range of Wyoming approximately 50 miles to the west around 3 to 4 hours prior to reaching western Nebraska, producing several confirmed tornadoes along its path. Environmental conditions across Scotts Bluff County continued to support the potential for tornadoes, with abundant moisture pooling in the Platte River Valley and favorable east-to-southeast winds near the surface with a strong southwesterly jet stream aloft. The supercell produced 7 additional confirmed tornadoes (6 in Scotts Bluff County and 1 in Morrill County), most notably including an EF-2 tornado which tracked approximately 1-3 miles ENE of Gering between 7:38 PM and 7:45 PM MDT. A Tornado Emergency was in effect for Gering and Scottsbluff from 7:31 PM until 8:00 PM MDT, which was the first ever issuance of this product from the NWS in Cheyenne. Numerous instances of baseball to softball sized hail occurred across Scotts Bluff County including the city of Scottsbluff. A second intense supercell developed and tracked across Scotts Bluff County in the wake of the first tornadic storm, producing a second swath of very large (baseball sized) hail over the same area. In addition to this primary focus area for intense storms, other isolated storms also brought quarter sized hail, 60 MPH wind gusts to portions of the western Nebraska Panhandle.

Event narrative: Based upon drone imagery provided by the Newton County Emergency Management Agency, this tornado touched down in a field northwest of 500S Road at 125W Road southeast of Morocco. The tornado tracked to the southeast over mainly rural areas, destroying a grain bin and damaging a few trees. The grain bin appeared empty but was anchored to the foundation; only a few anchors remained attached to foundation. This tornado left a narrow, convergent path of flattened corn over most of its track.
Episode narrative: A weak low-top supercell brought rain and winds, but no lightning to Fleming County during the early morning hours of August 10, 2023. However, within this system, a weak tornado developed and tracked across portions of the county. By daybreak, dispatch and emergency management began receiving reports of damage that had  occurred in the Beechburg community just east of Flemingsburg. Radar did show some weak rotation that moved across this location. After an NWS Damage Survey, it was determined that an EF-0 tornado had touched down, starting near the intersection of  Beechburg Road and Colgan Road, and continued about a third of a mile down Colgan Road before dissipating. Based on the path of damage, it is also likely that this tornado only lasted about a minute, and skipped a few times along it's track before  dissipating.

Event narrative: Actual storm survey determined that tornado likely started and ended within the same minute, only traveling 0.3 miles in that time span. Starting location was 38.4464/-83.6408 and ending location was 38.4482/-83.6352. Due to limitations within the Storm Data interface, could not track the path of the storm since it shows the same start/end time. 

Damage was first observed on a property at the intersection of  Beechburg Road and Colgan Road, where the tornado directly  impacted several structures, including a wooden barn, a mobile  home, a shed, and a larger open barn located behind. All sides of  the mobile home sustained damage, including a large board impaled into the roof, and some blunt force impacts from pieces of the  nearby barn that collapsed. Vehicles parked to the north and  northeast of the barn sustained heavy damage as it collapsed and  sections became airborne. Next the tornado hit a larger open- air barn housing heavy equipment. Roof panels were torn off the west  side of the barn and sent up to 200 yards to the ENE. A little  ways down the road, another mobile home sustained blunt force  damage, including a large hole that punctured through into the  interior, as well as wind damage to all sides. Metal roofing from  the barn was found in a grove of trees to the northeast of this  house. The next door neighbor to the east faired better, but it  had debris from the metal barn in their yard, minor wind damage,  and a flagpole which was bent at the base laying northward.  Slightly farther up the road, the next property sustained major  tree damage, including several snapped trees and an uprooted tree, though no structural damage. The tornado picked up a goat  enclosure in a grove of trees, lifted it over a fence, leaving the fence untouched, and then tore the structure apart and twisted it across the front yard of the property. Additional tree damage was witnessed just past this location before the tornado lifted and  dissipated.
Episode narrative: As a strong mid-level jet streak pushed northeast ahead of an upper-level low pressure area in southwest South Dakota, numerous thunderstorms developed along a weak surface boundary during the mid to late afternoon hours in far eastern South Dakota.  While instability was somewhat limited at a maximum of around 1000 J/kg, a very low LCL and concentration of 0-1 km bulk shear supported the development of four brief tornadoes.

Event narrative: National Weather Service meteorologists surveyed damage in southern Coosa County and determined that it was consistent with an EF3 tornado, with maximum winds near 140 mph.  This long track tornado began in Autauga County and tracked across northwest Elmore County and into southern Coosa County just west of Highway 231. Structural damage across Coosa County continued to consist of roof uplift or removal and damage from wind-blown debris and fallen trees.  A manufactured home was destroyed near Highway 231 along with numerous uprooted trees. Radar showed a debris ball in southern Coosa County which matched ground observations of a truly extensive area of snapped pine trees along McKissick Road, located between the communities of Speed and Equality. The volume of snapped trees was enough to assign an EF3 rating for this segment of the tornado path. Additional significant damage occurred along County Road 18 where vehicles were moved or flipped, numerous trees were snapped, and site-built homes were heavily damaged with one destroyed. This was another area assigned EF-3 intensity. The tornado continued northeastward toward the Coosa/Tallapoosa county line where additional, relatively less intense timber damage was noted. The tornado crossed into Tallapoosa County about one mile south of Newman Road.

Event narrative: This tornado began in the area of the River Bend neighborhood south of Route 113 and west of Kankakee, where multiple trees were uprooted or had large limbs snapped. The tornado appeared to cross Route 113 near the First Baptist Church and produced concentrated tree damage along Springview Drive. It then moved east into Bradley and Kankakee, where sporadic tree damage was observed into the Pioneer Park area. The tree damage again became more significant as the tornado moved toward Hammes Avenue, especially north of Spruce Street, where numerous trees were uprooted or had limbs snapped. In the area beyond this point to the east of I-57, there was no additional damage observed, but that area is much less developed compared to areas west of the interstate. Along this entire route, little to no structural damage was observed, though the Valspar facility along Fair Street had a partial collapse of one wall. The storm lifted just after crossing I-57 near Green Street. South of the track, sporadic straight-line wind damage was observed.
Episode narrative: During the evening of July 12, scattered thunderstorms dropped 13 tornadoes across far northeast Illinois, primarily within the west of northwest suburbs of Chicago. Of these 13 tornadoes, three were determined to be EF-1 with the remaining 10 being EF-0.
