Episode narrative: A vigorous upper level system passed over the southern Great Plains on Sunday February 26th, 2023. This brought widespread strong winds and blowing dust to the Panhandles, particularly during the late afternoon and evening hours as a Pacific cold front rapidly moved eastward, with the large amount of dust leading to greatly reduced visibility and treacherous driving conditions. East of this front, severe thunderstorms developed which led to two tornadoes in the southeastern Texas Panhandle and additional damaging winds.

Event narrative: Video evidence indicated a very brief tornado about 2.6 miles northwest of Lela. No damage was observed. The size, strength, and duration of the tornado were estimated based on a combination of video and radar data.
Episode narrative: A supercell thunderstorm developed in the far southern Texas Panhandle during the late afternoon of the 21st of June. This supercell moved south-southeastward through the western Rolling Plains during the evening and eventually moved into the Texas Big Country and the San Angelo National Weather Service forecast area around 2200 CST. This storm quickly intensified in Motley County just north of Matador where the first of five reported tornadoes occurred around 1850 CST, however no survey was conducted as no damage was reported. This storm then produced a third of a mile wide tornado that went through the west side of Matador around 1900 CST killing four people and injuring 15 others. One of the fatalities was an 85 year old woman at home. A 59 year old truck driver died while in his semi-trailer. The final two fatalities were a 43 year old male and 23 year old male in a recreational vehicle. Peak wind gusts corresponding to the observed damage were estimated to be in the 145 mph to 165 mph range, resulting in an EF-3 rating. This rating was determined through consultation with engineers from the Texas Tech University National Wind Institute, who also performed a damage survey in Matador. It also produced extremely large hail with the largest stone measuring 4.50 inches in diameter on the east side of Matador. The storm continued moving to the south-southeast where a 75 mph gust was reported at the Roaring Springs West Texas Mesonet site at 1922 CST, most likely associated with a rear flank downdraft surge. As it entered northern Dickens County another tornado was reported by an off-duty NWS employee approximately 5.5 miles northeast of Afton, however no damage was reported with this tornado. A second supercell produced a brief tornado west-southwest of Matador at 1937 CST that also produced no known damage. Shortly afterward, that supercell began to merge with the initial supercell with the fifth and final tornado being reported on US Highway 82 approximately eight miles east of Dickens and no damage was observed with this tornado either. As the storm continued to move to the south-southeast a broad rear flank downdraft was noted on radar with the peak measured gust of 109 mph at the West Texas Mesonet site in Jayton at 2107 CST with 19 minutes of continuous severe wind gusts. These strong winds also occurred with hail up to four inches in diameter leading to damage observed along State Highway 70 in northeast Kent County including in and around the towns of Girard and Jayton.

Event narrative: The National Weather Service conducted a storm assessment survey across Eastern Jefferson County from storms early Saturday morning just after midnight on April 1. The survey team found an EF1 tornado with maximum winds of 90 mph. The tornado went a little over 4 miles intermittently and crossed over into extreme northwestern Shelby County.

The tornado first touched down just east of I-265 (Gene Snyder Freeway) at a large warehouse by Terra View Trail. The western edge of the warehouse was partially peeled back and insulation was thrown off to the north through easterly directions. A portion of the tornado was aloft, based on the lack of tree damage initially, until it hit a plastic surgery center off of Bush Farm Road which sustained roof damage. This consisted of shingle and fascia damage. Most of that was cleaned up and repaired by the time of the survey. There was insulation on the backside of the three-story building.

The street sign was bent back and turned to the northeast at Arnold Palmer Boulevard near Chestnut Ridge. There was sporadic tree damage along Chestnut Ridge Circle, and at 15107 Chestnut Ridge Circle a doorbell camera showed an intense loud 20 second burst of wind and rain. The homeowner stated that the entire house was shaking, and several trees were snapped and twisted, and their garbage tote was found two houses over behind that house.  Behind their house across Lake Forest Country Club were several uprooted and twisted trees. Most of the trees were laying from the north northeast to due east. There was sporadic wind damage along Champion Lakes Way, with several houses sustaining gutter and fascia damage. The maximum wind speed in Lake Forest was 85 mph with a width of 75 yards. 

The tornado took a southward jog along Flat Rock Road and increased in wind speed and width. All along Flat Rock Road there were dozens and dozens of trees snapped, twisted and uprooted. The width of the tornado increased to 130 yards wide and the wind speed increased to 90 mph. Several residents heard a distinct roar and had their ears pop. There was shingle and fascia damage.

The tornado took a northward jog and crossed into northwestern Shelby County.
Episode narrative: A storm system and its associated cold front racing across the Great Plains combined with moist southerly flow at the surface resulted in a line of thunderstorms that impacted Middle Tennessee on February 16, 2023. As this line moved into the area that provided abundant wind shear and sufficient instability, they strengthened and quickly turned severe. Several reports of large hail and damaging winds were received, and three tornadoes were confirmed across southern Middle Tennessee. While these three tornadoes were weak with 2 EF0s and 1 EF1, they were the first tornadoes in Middle Tennessee since January 1, 2022.

Event narrative: A low end EF-1 tornado touched down near Big Rock Creek northwest of Farmington and moved northeast, damaging a barn and blowing down dozens of trees west of Bethbirei Road. A home on Bethbirei Road was damaged by a large uprooted tree falling on it, and several nearby outbuildings were also damaged. Further northeast, dozens more trees were snapped and uprooted south of Wade Brown Road, and an RV was blown over with a horse trailed partially blown on top of it. A home further east of Wade Brown Road suffered minor exterior damage, while several nearby barns were damaged or destroyed. Other trees and a nearby barn on Stegall Road were heavily damage, with tree limbs and debris from the barn blown up to 600 yards away across adjacent farm fields before the tornado lifted. Damages are estimated.
Episode narrative: A cold front pushed a line of thunderstorms with strong wind gusts and some large hail, from west to east through several counties of Central New York. There were some reports of downed trees and power lines. Ahead of the main line of storms, a tornadic storm developed in Sullivan County. An NWS survey rated the tornado as an EF-2. Surveyed areas included multiple downed trees and structures that sustained damage including a couple of old barns that were destroyed. Fortunately, there were no injuries or fatalities.

Event narrative: A tornado touched down north of Jeffersonville, along Callicoon Center Road near Laundry Brook, damaging trees. The tornado then moved north, passing through a roadless area between Sander Road and Wahl Road, before crossing Hessinger and Lare Road, snapping several trees and causing minor structural damage. The tornado continued north, crossing John Dietz Road, producing a large blowdown of hardwood trees, and damaging skylights in a nearby residence. Damage in this area rated between EF0 and EF1.

The worst damage, particularly to structures, occurred on a farm and nearby residence on either side of Hahn Road. Severe damage to historic barns, a garage, and outbuildings occurred. A 180 foot truss tower collapsed, completely bending into three sections. A nearby house received seemingly minor damage, but frame damage may have occurred as interior walls were reportedly cracked, and doors unable  to close. A large blowdown of mixed trees also occurred in this area. Damage ranged from EF1 to EF2 in this area. 

The tornado continued north, causing another hardwood blowdown off of Gulf Road, with mostly tree damage along nearby Dutch Hill Road. The tornado then passed through Roscoe, NY, with more sporadic uprooted trees, and lifted as it moved into Rockland, NY.
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.

Event narrative: The tornado first touched down near the intersection of Jacksonburg Road and Oxford Middletown Road, where some minor roof and tree damage was observed. Damage was more pronounced at properties along Middletown Eaton Road. Several homes had  fascia and shingles removed. One house even lost some plywood underneath the shingles.

The strongest winds occurred at a property on Elk Creek Road, just north of the bridge over Elk Creek. A home on the east side of the road had the roof removed from the second story, with the back wall also failing in the process. This is where the tornado is likely to have been at its maximum intensity, with the degree of damage and structural damage to the home supporting an estimated wind speed of 110 mph. A barn at this property was leveled, with some debris moved slightly west from its original location and other debris strewn downwind to the northeast across a field.

Roof and tree damage was observed at several properties on both sides of West Alexandria Road, with varying degrees of shingle removal, and a few patches of trees with a significant percentage of the trees snapped off. Damage continued east-northeast to Dickey Road, with debris from these properties found as much as a third of a mile away, in a field on the east side of the road.

At one property on Hetzler Road, some minor roof and tree damage was observed. This is believed to be the last damage from the tornado.

Event narrative: The tornado began south of Darby Creek Road in the Fox Lair Farms neighborhood where two single-wide manufactured homes were flipped on their sides. Minor damage continued through the neighborhood before the tornado crossed Darby Creek Road, damaging a single property. On this property, the garage roof was lifted off the structure and landed on the other side of Darby Creek Road. 

The tornado likely crossed Big Darby Creek, however, damage could not be verified due to the lack of accessible roads. 

The next area of damage was observed toward the town of Orient, where multiple abandoned structures were damaged at the Pickaway Correctional Institution south of town. This damage was verified through video shared on social media. Most of the structures had large amounts of roof panel loss which was scattered across a nearby field. 

The only signs of the tornado in the town of Orient was scattered building insulation found in trees. It is believed that the tornado likely dissipated as it entered Orient.
