Event narrative: An NWS Storm Survey found that an EF-0 tornado initially touched down on the west side of Dilley where damage to hardwood trees was noted. The tornado then moved in a northeasterly direction, causing damage to roofs of buildings on either side of I-35. The  tornado lifted on the east side of the interstate and covered approximately 0.7 miles over a span of 2 minutes. Maximum winds were estimated at 75 mph.
Episode narrative: During the late morning and afternoon hours on May 7th, an occasionally broken line of strong-to-severe thunderstorms moved from north to south across central Kentucky. These storms were not associated with any low-level front; however, they were the continuation of convection which fired during the late evening hours on May 6th over northern Illinois and had moved south-southeastward along with a mid-level shortwave disturbance transiting along the top edge of larger scale ridging. Ahead of the line of storms, a moderately unstable environment existed. Initially, around 500 J/kg MLCAPE was present as storms approached the Interstate 64 corridor; this increased to between 1000-2000 J/kg later in the day across south central Kentucky as the atmosphere had more time to destabilize. Wind shear was modest at best, but was sufficient to keep storms going across the region. Most portions of the line of storms were sub-severe, but a few isolated areas of severe winds, hail, and one tornado occurred as the line moved through central Kentucky.

Event narrative: A Valero gas station sign was pushed to the east and towards Highway 55 (Taylorsville Road), with some of the sign damage thrown across Highway 55 onto Pearce Industrial Road. The next damage was at the Black and Decker plant off of Harry Long Road. There was significant roofing damage across several portions of the roof to be lifted and thrown 30-40 yards. All of the debris from the roof was pushed to the east-southeast.       There were 3 business and home videos that all faced toward the Black and Decker warehouse, where you can definitely see a narrow funnel in contact with the ground. This was key to this tornado rating as drone photography showed almost no damage between the Valero Gas Station and B & D roof structure. There was not a single tree  snapped or twisted and a large cell tower right in its path had no damage. Based on the videos and the damage to the B & D roofing structure, the survey team came up with a EF0 75 mph rating, with a width of 30 yards.        The survey team drove across several intersecting roads within a two mile radius along old Finchville Road over to Zaring Mill Road and found no other damage.
Episode narrative: A line of thunderstorms moved across the region during the late afternoon and evening. Multiple tornadoes occurred with the line of storms in Central Louisiana.

Event narrative: First noticeable damage was near Sandhill Road Southeast of the intersection with Joe Smith Road. It intersected Joe Smith Road and Crossed Cora Road. The last visible damage is near the end of J Harper Road. Only tree damage was noted. Maximum estimated wind speed was 80 mph.
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 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: A funnel cloud that moved over much of Phillips County touched down as a tornado briefly northwest of Lexa as it crossed Highway 1. An emergency manager along with several public spotters observed the tornado briefly touching down over open fields. No damage indicators were found and thus the tornado is rated as an EF-U. Nearby reports of damage were from straight-line winds that were associated with the same storm's rearflank downdraft. A special thanks goes out to Phillips County Emergency Management for their assistance during this survey.

Event narrative: The tornado touched down at the Sporting Club at the Farm in Floyd County, Indiana before it traveled a short distance and cross the river into Kentucky. The tornado entered Kentucky in the Lake Dreamland area of West Louisville in western Jefferson County. Significant tree damage was observed along River Front Drive and continued along Kale Dreamland Road where several hardwood trees were snapped or uprooted, along with many large branches down.       The tornado continued along Kramers Lane toward Van Winkle Drive, where damage appeared to be sparser with large branches down in some isolated areas. Very isolated areas of large branches down continued through the Heatherfield and St. Dennis neighborhoods (and across I-264 Watterson Expressway) and toward the Louisville  Memorial Gardens. Along Lynn Lea Road, the tornado regained strength and continued through homes along Kendall Lane west of 31W Dixie Highway. Trees were snapped heading on the east side of Hunters Trace neighborhood. Significant tree damage was observed along Malcolm Road just north of Gagel Avenue. Several hardwood trees were uprooted or snapped with damage consistent with 94 mph winds in this location. No visible damage was observed to the southeast beyond Gagel Avenue where the tornado ended.
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 began south of Section where trees were uprooted and continued northward where it overturned a manufactured home, damaged underpinning and roofs of manufactured homes, and downed powerlines. The tornado then continued to uproot and snap trees as it tracked into Dutton, AL. A home had minor roof damage off of Hodge Road and County Road 124. The tornado removed metal roofing on a chicken house off of County Road 19 and then lifted.
Episode narrative: During the afternoon of the 18th, quite a bit of moisture and unstable air was present across the combined Oklahoma and Texas Panhandle. During the heat of the day several supercell thunderstorms created large hail, up to 2.5 in diameter, heavy rain, and damaging wind gusts. One of the supercells even produced a short lived tornado. Continued storm activity into the overnight hours from the help of an upper level system continued to feed the overall rain amounts leading to widespread flooding problems across the area.

Event narrative: A brief tornado touched down just to the east of FM2373. It caused some broken tree limbs and tossed a dumpster several yards back to the south. It resulted in damage to an attached garage, collapsing the structure. It also blew some horse trailers over in a nearby field. The tornado lifted in an empty field.
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.

Along its path, it downed large branches and snapped/uprooted approximately 15 hardwood trees in a convergent pattern.
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: A National Weather Service and Lauderdale County Emergency Management Agency damage assessment team surveyed damage consistent with an EF-1 tornado near Anderson. Peak winds were estimated at 97 mph. The main damage indicators for this assessment were from uprooted or snapped trees and minor structural damage, mainly to roofs. The tornado touched down off County Road (CR) 49, near the West Fork of Anderson Creek and tracked east-northeast along Highway 64. Along Highway 64, between CR 508 and CR 93, numerous trees were uprooted with a couple of snapped trees that fell on at least one home. Near CR 508, one home sustained roof damage with greater than 20% loss of roofing materials. Additionally, a small garage was completely destroyed when the garage door caved in. The tornado began tracking more northeast as it passed CR 93. More trees were uprooted and sporadic limb damage was noted through CR 207 as the tornado lifted.
Episode narrative: Large hail and damaging winds were reported across western Kansas.

Event narrative: A video of a funnel cloud that became a landspout was shared by EM. The landspout formed near St. Mary's near 401 East Coyners Street around 4:17 pm and persisted through 4:22 pm where outflow boundaries converged. There was broad rotation in the video around a thin, elevated condensation funnel. Debris was seen rotating around the condensation funnel and was mostly vegetation (leaves). Some objects were blown around on the ground, but significant damage did not occur.  There was also some wind blown debris near the Meeting Street Boat Ramp in St. Marys.
Episode narrative: On the evening of May 7th, a line of thunderstorms produced severe winds, severe hail, heavy rain, and even two landspouts across parts of the southern and southwestern Chicago metro. The heaviest of the rainfall occurred along a narrow corridor stretching from far southern Lee County southeastward into east-central Kankakee County where widespread 2+ inch rainfall totals were reported with a few spots seeing between four and five inches of rain. Additionally, strong outflow winds from nearby thunderstorms kicked up significant amounts of blowing dust across parts of southern LaSalle County and towards the I-55 corridor in Livingston County. This was preceded by an abnormally dry period stretching back to early April leading to dry soil conditions in the area. Multiple reports of near-zero visibility resulted in the issuance of two Dust Storm Warnings, the first such warnings issued by the Chicago WFO.
