Event narrative: A thin rope tornado began along Interstate 80 around 5 miles southwest of Kimball at 8:01 PM MDT. The tornado remained over mainly open farmland south of the Interstate. The tornado did impact one property, where a cinder block outbuilding was destroyed. Cinder blocks were thrown approximately 50 yards in a scattered debris pattern north of CR 28. Additionally, a large shipping container was moved off its foundation by 6 inches. Finally, a large tandem-disk plow weighing 20,000 pounds was pushed approximately 15 feet in a field just north of CR 28. The tornado dissipated about 4 miles WSW of Kimball at 8:05 PM MDT.
Episode narrative: A weak shortwave trough lifted from northern Mexico into west Texas on the 25th. While this contributed to increasing (and sufficient) wind shear, only weak instability was present across the region (owing to widespread rain showers/clouds). Despite this, a weak quasi-linear convective system (QLCS) developed and swept across portions of south-central into east-central Oklahoma during the early evening. Localized pockets of low-level instability yielded sufficient conditions for the development of two weak/brief tornadoes across these areas.

Event narrative: NWS storm survey found the path of a very brief and weak tornado that touched down along Breeland Dr just off Leeds Rd. Damage consisted of a few downed large tree limbs and one split tree. Path length was estimated due to inaccessibility beyond Breeland Dr.
Episode narrative: Isolated severe thunderstorms, including a few supercells, developed on the afternoon of November 20th from East Texas into parts of Northern and Central Louisiana. These thunderstorms continued to mature ahead of an approaching upper-level trough and associated cold front shifting east from the Southern Plains. Modest destabilization occurred within the downstream air mass, most notably in Louisiana along a retreating warm front with abundant low-level moisture and a large area of mid and upper 60s to near 70 degree dew points. The warm sector continue to expand northward ahead of the approaching upper trough, contributing to further destabilization through mid to late afternoon. Low-level flow also continued to increase ahead of the upper trough, with the resulting combination of buoyancy and shear contributing to an increasing threat for severe weather as a few thunderstorms became severe and produced some damaging wind gusts across portions of North Central Louisiana, as well as an isolated tornado in Natchitoches Parish.

Event narrative: An EF-1 tornado with estimated maximum winds near 105 mph touched down in extreme southern Natchitoches Parish in the Kisatchie National Forest along Forest Road 306, tracking northeast across Highway 119 through the Gorum community. Numerous trees were snapped and uprooted along its path, with the tornado crossing Andy Cedars Road, where a portion of a tin roof was ripped off of a home. The tornado crossed Janie-Gorum Road, where additional trees were snapped and uprooted, a tree fell onto a single family home, and a camper was blown over. Additional trees were downed and a roof was ripped off of a double-wide mobile home farther east along Janie-Gorum Road, before the tornado lifted just to the east of Sunk Hill Road. The estimated path length was 8.8 miles, with a path width of 150 yards.
Episode narrative: A long-lived supercell thunderstorm developed over the higher terrain of the central Laramie Range in far northwestern Laramie County near the Platte County late in the afternoon on 6/26. This thunderstorm quickly became severe as it tracked to the east-southeast across northern and eastern Laramie County through the early to mid evening hours, before exiting into western Nebraska. Multiple tornadoes were reported over rural eastern Laramie County, with an official NWS damage survey confirming two EF-1 tornadoes to the west and southwest of Albin, and an EF-0 tornado 8 miles ESE of Albin. In addition to the tornadoes, this storm also produced up to baseball sized hail near Gun Barrel. Additional isolated severe storms occurred over Converse County later in the evening.

Event narrative: A very brief tornado was observed over the intracoastal waterway along the Belleair Beach causeway at 11:34 AM EST (1534Z). At 11:35 AM EST (1535Z), the tornado moved onshore and damaged the roof of an apartment building before dissipating.
Episode narrative: A broad area of low pressure moved slowly across the state through the day, with a number of associated weak boundaries that resulted in off and on convection through the day. In the afternoon the primary boundary, acting almost as a dry line, was draped across Iowa from northwest to southeast. With good 0-3 km CAPE exceeding 124 J/kg and surface vorticity to enhance stretching in the vicinity of the surface low, conditions were good for funnel clouds and tornadoes. As the band of thunderstorms moved slowly across central Iowa it produced two weak tornadoes along with three funnel clouds.  One tornado was rated EFU as it remained in rural farmland and the other was an EF0 with minimal damage produced to a tin building.

Event narrative: A brief EF0 tornado touched down just west of Highway 319 with trees blown down along the highway.  This tornado was confirmed by photos of trees down corresponding to the TDS location on radar.
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: An EF-0 tornado occurred on the afternoon of September 11, 2023, in the Dagsboro area of Sussex County, Delaware.  The brief tornado began along Adams Road just east of Dagsboro where damage to multiple structures and trees was observed. A shed in a backyard of a home on Adams Road had partial roof and wall collapse, and an additional larger and more structurally sound shed just feet from the first one was shifted off of its foundation, had the door blown off, and had partial roof collapse. Damage to three homes along Adams Road was noted with glass windows blown out and partial siding and shingle loss. Numerous  large softwood trees were uprooted along the wood line behind the homes on Adams Road along and had large branches snapped off of the trunks.

Further south on Adams Road, very close to the intersection of Tingle Lane, minor loss of siding was noted on a home as well as some more tree and limb damage. This is likely where the tornado reached its maximum width of around 370 yards.

The tornado then continued a short distance down Piney Neck Road to near the intersection of Wild Goose Way where another softwood tree was uprooted in the backyard of a home. The tornado likely occluded at this point and lifted as no further damage was found further downstream.

The National Weather Service would like to thank Sussex County Emergency Management Agency, local Skywarn spotter coordinators, and the public for their assistance with this survey.
Episode narrative: A weak stalled boundary over the coastal waters triggered thunderstorms in some marine and land areas during the morning and early afternoon, causing some stronger wind gusts with the stronger storms. One particular cell took advantage of colliding boundaries and a moist airmass to produce a waterspout over the Mississippi River. The waterspout moved onshore and caused minor damage to buildings. The activity tapered off throughout the day as the front washed out.

Event narrative: A weak tornado touched down just off the MS River in Kenner. It moved north along Minor Street and dissipated around Short Street. The windows of a police van were blown in with minor damage to the Kenner Fire Dept building. Tin roof was peeled off the theater and was blown south, a good indication of rotation. Other minor building damage was noted near the track. This determination was a combination of surveys from local emergency management, radar analysis and pictures and videos of a rotating funnel cloud in the area.

Event narrative: A tornado touched down just east of the intersection of Odom Lane and Cedar Springs Lane south of Blakely. Several snapped pine trees were found, consistent with EF-1 damage. The tornado then crossed Georgia Highway 39 where several large branches were broken off. The top bar of a chain-link fence was pulled out and a wooden fence was also blown down in this area south of Blakely. The tornado then moved eastward, roughly paralleling south of Damascus Street, snapping and uprooting both hardwood and softwood trees. The tornado crossed Waller Road south of Damascus Street, causing significant roof damage to a single-family home as well as uprooting and snapping several trees nearby. A large area of snapped pine trees was spotted south of Damascus Street between Waller Road and Sandy Bottom Road. The tornado then turned slightly to the northeast, crossing the intersection of Damascus Street and Sandy Bottom Road. Here, the damage was consistent with EF-2 intensity. Significant roof damage was done to a single-family home and numerous hardwood and softwood trees were snapped in the area. The tornado continued northeastward toward Giles-Hightower Road near the intersection of Mays Ford Road. A barn's walls collapsed here along with many other snapped and uprooted trees. Tree damage continued to the northeast south of Mays Ford Road, generally consistent with EF-1 damage. More tree damage was observed along Old Damascus Road and Georgia Highway 45. The tornado turned a bit more northeastward and crossed Georgia Highway 216 where more snapped and uprooted trees were found. Another area of EF-2 damage was then observed along Quail Country Road in far northeast Early County. Large sheds were completely destroyed here with large swaths of pine trees snapped. A double-wide manufactured home lost its roof and a couple exterior walls.  Damage cost was estimated.
