The foundation of  a manufactured home was slightly shifted with additional minor  damage to the roof and window of a nearby residence. Inhabitants  were home at the time of the tornado and described it as an  intense, sudden wind that did not last long. A swath of downed  pines to the east of the manufactured home was where the worst  damage was found with winds estimated near 85 mph. As  the survey continued northeast from the residence, tree damage  became much more sporadic. The last of the damage was found at a  residence off of Fair Hill Rd with no damage continuing Northeast  of the location towards Interstate 81. Resident of home was also  present at the time of the tornado and also described it as a sudden  wind that lasted 15 to 30 seconds.
Episode narrative: A few discrete supercells formed across the combined Oklahoma and Texas Panhandles on during the afternoon of the 28th, before a complex of storms moved from the northwest to southeast across the combined Panhandles. One of the discrete cells in the afternoon formed over Beaver County in the Oklahoma Panhandle and not only produced hail up to 2.5 in diameter, but also sat over the same area producing flooding rains. In the TX Panhandle another supercell produced hail stones up to 3.3 in diameter over Hansford County before moving into Sherman County where it produced a brief tornado.

Episode narrative: A regional tornado outbreak occurred during the late afternoon of Friday, March 31, 2023, and continued into the early morning hours of Saturday, April 1, 2023. This outbreak covered portions of the Ohio Valley, and the Middle and Lower Mississippi Valleys, including a good portion of the Mid-South and stretching into the Tennessee Valley. On Friday, March 31, a surface low was located near La Crosse, WI, with a cold front stretching south into central/southwest Missouri, western Arkansas, and into eastern Texas. Surface temperatures were mainly in the 70s to approaching 80 degrees with surface dewpoints in the lower to middle 60s, yielding Surface-Based CAPE (SBCAPE) values between 1500-2000 J/kg by Friday evening. Favorable upper-level divergence produced by the right entrance region of a 140-kt jet streak at 300 mb provided ample lift to produce strong to severe thunderstorms across the region. Directional and speed shear were impressive with 70-80 knots of Effective Bulk Shear present and 0-1 km Storm Relative Helicity values between 500-600 m2/s2, all more than enough for organized thunderstorms across the area. Discrete supercells started to develop across the Lower Mississippi Valley during the afternoon hours on March 31, 2023, eventually tracking into the Mid-South by late afternoon. The first supercell that developed in the Mid-South produced an EF-3 that caused major damage in Wynne, Arkansas. Tornadic supercells continued to produce significant tornado damage across the Mid-South into the early morning hours of April 1, 2023. The hardest hit areas besides Wynne, Arkansas included Covington, Tennessee, and McNairy County, Tennessee. Overall, 14 tornadoes occurred across the Mid-South along with several reports of wind damage and measured damaging wind speeds. Eighteen people in the Mid-South lost their lives in this outbreak.

Event narrative: NWS meteorologists determined an EF-1 tornado touched down in northern Marshall County on the evening of March 31st. The first evidence of tree damage occurred near Anderson Lane west of Highway 311. The tornado continued to the northeast and crossed Highway 311 where hardwood trees were snapped. Additional hardwood tree damage was noted on Hogan Road and South Slayden Road. The tornado crossed Highway 72 with hardwood trees snapped on both sides of the highway. A single-family residence on Kennedy Road sustained roof damage with hardwood trees uprooted on the property. The last evidence of damage was on Early Grove Road where a few trees were uprooted. The tornado dissipated in a field to the northeast of this location. Peak winds were estimated at 95 mph.
Episode narrative: A severe line of thunderstorms rolled through north Alabama during the late evening hours of the 24th into the early morning hours of the 25th, producing 7 tornadoes. An embedded supercell thunderstorm with a history of tornadoes in Mississippi moved east-northeast across northwest Alabama, yielding another two tornadoes in Lauderdale County in Florence and near Anderson. Associated with this line, multiple narrow swaths of intense damaging winds of 60 to 90 mph occurred across the Shoals metro area, including Sheffield, Tuscumbia, Muscle Shoals and Florence.  The winds caused widespread power outages, damaged numerous structures, and toppled or snapped numerous trees, power poles and power lines. A few trees and power poles were dropped onto residences and vehicles, either destroying or heavily damaging them. Roof damages were reported at many locations as well. All told, an estimated #### million in damages occurred, the majority in northwest Alabama in Colbert and Lauderdale Counties.  As the line continued east, additional tornadoes were spawned in Lawrence, Morgan, Jackson and DeKalb Counties.

Event narrative: The tornado touched down near the intersection of Sweetwater Avenue and Huntsville Road in southeast Florence. The tornado nearly paralleled Sweetwater Creek as it tracked northward. Along Sweetwater Creek and Sweetwater Avenue, numerous trees were uprooted and snapped and structures and small outbuildings were damaged. There was also minor room damage to a single family home.  As the tornado crossed Highway 43, more trees and minor structure damage was observed near Mall Road and north of Hough Road. The tornado approached Hunter Ridge subdivision northeast of Florence and south of Saint Florian along County Road 61, removing part of a roof at the back of the neighborhood. The tornado then moved northeast into the Plantation Springs subdivision, damaging roofs to two homes on the southeastern corner of Plantation Springs Drive around the Blackberry Trail Golf Course. The tornado then strengthened to its strongest and widest point between Cottonwood Trail and Karley Lane, producing the most widespread structure damage along its path here. About half of the roofs of several homes were destroyed, and the backside of the homes sustained severe damage as the tornado moved through the area. At this point, the tornado was about 100 yards wide, and produced  peak winds of 120 mph at this location. The last house on the northeast corner of Plantation Springs Drive sustained the worst damage near the golf course, with more than half the roof destroyed and two rooms with walls collapsed at this location. The tornado lifted shortly after this point.
Episode narrative: A prolonged damaging gradient wind event combined with an intense squall line during the daylight hours of the 3rd to produce widespread wind damage and impacts to the region. Numerous power outages resulted from power poles being snapped and power lines being brought down.  All told, thousands were without power in north Alabama for at least for a couple of hours, and in some cases lasting into the next two to three days. Hundreds of reports of trees or limbs being knocked down were received, in many cases on homes, vehicles and other structures. Sadly, two people were killed outside their homes from fallen trees while picking up debris after the line of thunderstorms went through and additional high winds developed.  Other minor injuries were also reported including one utility worker who was working to restore power.

A powerful low pressure system intensified rapidly as it moved northeast from Texas through Arkansas, southeast Missouri into western Kentucky.  In doing so, very windy conditions developed across the Tennessee Valley ahead of an associated cold front and squall line. South winds increased to 35-45 mph, with gusts of 55-60 mph at times. An intense squall line moved in from Mississippi during the mid morning hours, sweeping east across the rest of the area through the midday hours. Peak wind gusts of 50-60 mph were reported frequently, with one gust up to 77 mph at Pryor Field in Decatur (Morgan County) and 69 mph at the Huntsville International Airport (Madison County). Also, at least two tornadoes were spawned by the line in Jackson County.  Behind the line of thunderstorms, the sky cleared out rapidly, but southwest winds intensified as well, with 35-45 mph sustained winds, gusting at 55-65 mph. The winds finally subsided quickly near sunset, but not after additional damage occurred.

Event narrative: A tornado tracked out of far east central Lawrence County into Morgan County.  Minor damage was noted around Danville High School with the football scoreboard partially destroyed. The tornado intensified as it tracked east-northeast toward Targum Road. Uprooted trees, minor damage to a home, and a destroyed carport were observed. Tracking east, the tornado uprooted and snapped a significant number of trees along Iron Man Road and Forest Chapel Road. While there was heavy structural damage to single-family homes, the bulk of the damage was due to trees falling on houses. The tornado remained on the ground uprooting trees and tracking toward Vaughn Bridge Road. Near the Vaughn Bridge and Vest Road intersection, the tornado lifted and snapped the anchoring system of a single-wide mobile home. This caused the unit to overturn and roll, destroying the home. One fatality was reported at this location. Given the degree of damage, and strapping of anchors to the I-beam, the damage indicator held consistent with expected wind speed values. As the tornado tracked east, numerous trees were uprooted causing structural damage along Highway 31 and further east on Sparkman Street and through Bethel Road. The tornado likely lifted before the Bethel Road and I-65 intersection.
Episode narrative: A shortwave tracked through the eastern Great Lakes early on the morning of July 27th and moved into New England by the afternoon hours while a stalled boundary draped remained draped across the area.  This allowed for a favorable set-up for rotating storms due to very high low level helicity values.  A discrete supercell formed in Cheshire County bringing a relatively long tracked tornado and large hail.  The storm weakened with the tornado lifting before it briefly strengthened again over the Manchester area bringing with straight line wind damage.

Event narrative: A National Weather Service storm survey found that a tornado touched down near Base Hill Road in North Swanzey in Cheshire County and briefly lifted before touching down again near Route 101 near the Keene/Marlboro line. A few spotters viewed a rotating wall cloud and funnel as it moved near this location.  EF-1 damage was found in Marlboro due to damage to soft and hardwood trees along with some trees falling into parked vehicles. The tornado then intermittently skipped eastward nearly right along Route 101 downing hundreds of trees along the way but no structures were damaged, before arriving in Dublin.  It is there where trees fell on cars and buildings, ripped siding and shingles off of structures, broke windows, and knocked down several hundreds of large healthy trees. The tornado then lifted for good before reaching the intersection of Route 101 and Monument Road in Dublin.  Overall an estimated amount of around 1000 trees were uprooted or snapped.  5 buildings were partial damages, along with damage to small out buildings, some boats and a few parked vehicles.
Episode narrative: A southwest to northeast corridor of storm activity occurred during the afternoon through early evening across Northwest Kansas.  The largest hail reported from these storms was near Tasco.  The dry, loose ground, combined with the thunderstorms winds produced near zero visibility near Monument and Selkirk.

Event narrative: A supercell thunderstorm moving slowly southward through eastern Jones County produced a weak tornado 2 miles east of Funston around 9:13pm. Very little, if any, damage occurred during this phase of the event. At about 9:40pm, the tornado was moving southwestward before it was intercepted by an eastward-moving bow echo about 2 miles south of Funston. The bow echo pushed the tornado back northeastward and the circulation rapidly intensified for about five minutes. During this time, the tornado widened and caused significant damage to some homes at the intersection of CR376 and CR364. Two manufactured homes were rolled and or completely destroyed. It was noted that the hurricane straps failed on one of the manufactured homes, causing it to roll off of its foundation. A small single-family residence sustained significant roof damage and caused an enclosed porch to become detached from the home. The tornado continued northeastward for nearly a mile before becoming fully absorbed into the straight-line winds of the bow echo at about 9:47 pm.
Episode narrative: As a shortwave trough (and associated area of low pressure) advanced towards the Ozarks, widespread convection developed across eastern into southeastern Oklahoma. This included a severe thunderstorm that produced large hail across eastern Bryan County, Oklahoma.
