Episode narrative: As a low pressure system moved through the Upper Midwest region, its cold front which stretched to the south through the Lower Mississippi River Valley became the focus for thunderstorm development on the afternoon of December 9th. Initially discrete supercell storms produced wind damage and hail as they moved into northern Mississippi, and these supercells eventually grew upscale into a squall line of nearly continuous storms as the cold front pushed farther southeast into Mississippi. A few severe storms developed in advance of the cold front during the afternoon and early evening and also produced wind damage and hail.

Event narrative: An EF-1 tornado developed in northwest Jasper County and moved east-southeast. Scattered small pine trees were snapped, and some small trees were uprooted. A few hardwood trees were also uprooted. The tornado also took the tops out of a few trees and snapped large limbs. Much of the path was inaccessible as it passed through areas without any connecting roads. The tornado continued into Clarke County and ended near Enterprise where additional trees and power lines were blown down. Estimated maximum wind speeds in Jasper County were 85 mph. The tornado path was 27.4 miles across the two counties.
Episode narrative: Long duration severe weather event across the northeast plains, and most of the Denver metropolitan area beginning during the early afternoon hours.   Scores of  tornadoes occurred across Washington and Logan counties.  Several rounds of hail across the Denver metro, with ping pong ball sized hail in downtown, larger hail up to 2 inches in diameter at concert in Red Rocks Amphitheatre.  In all, seven patrons were hospitalized,  with 83 treated on scene.   A substantial number of attendees suffered welts, bruises and broken fingers trying to protect themselves.  Several suffered concussions as well.  A total of 33 tornadoes touched down in Washington County, with 3 reported in Logan County.  There were reports of at least one home damaged west of Sterling and one commercial building collapse in Sterling. The home was damaged by one of the tornadoes.

Significant flooding and flash flooding also occurred in portions of the plains, including Elbert, Arapahoe, Adams, Logan, Washington and Morgan counties. There were likely several rural roads that flooded due to the heavy rainfall.  There was a flood fatality just south of I-70 along Watkins Rd.  First responders found two stranded cars swept into a field, but its occupants had either gotten out or had been rescued. The third vehicle ended up west of Watkins and 6th Ave. in what is normally a dry creek bed. South Metroï¿½ï¿½ï¿½s water rescue team was then called out to do a water rescue but that operation turned into a recovery by the following morning.  Due to flooding, Watkins Road was closed between Interstate 70 and Jewell Ave.  Interstate 70 was also closed for several hours until water could recede from flooded underpasses. Minor flooding also occurred in portions of the Denver and the surrounding metro area.  Baseball size hail was observed in Washington County.  In Clear Creek County, a thunderstorm wind gusts to 68 mph was recorded.

Event narrative: An EF-1 tornado touched down near Old Stage Road at approximately 12:28 PM EST. The tornado was on the ground for 4 minutes and tracked east-northeastward for approximately 1.9 miles before lifting near United States Highway 70 along 7th Avenue. Most of the damage was associated with snapped and uprooted trees, and some subsequent building damage due to trees falling on several structures. There we no injuries or fatalities.
Episode narrative: A deepening surface low formed across the ArkLaTex region in the early morning hours on December 1st. In the warm sector of the low, thunderstorms formed along a convergent axis almost parallel to the upper-level flow, which caused training to occur over an urban area (Baton Rouge). That same batch of convection eventually cold-pooled out and raced east when a bowing segment produced a very brief tornado in Pearl River county, aided by a surging rear-inflow jet. After that convection exited the area, another batch formed during the late evening hours, with one cell becoming dominant and producing golf ball sized hail before the whole complex weakened.

Episode narrative: By mid-morning, clusters of storms were developing across NE Arkansas and the Missouri Bootheel. These storms continued across Western Kentucky and Tennessee for the late morning and afternoon hours. A few of these storms were strong to severe across Western Kentucky, including dime size hail reports in Fulton and McCracken counties. The most impactful storm was a supercell tornado which began in Fort Campbell and tracked northeastward from Montgomery County, TN to Logan County, KY, crossing southeastern Todd County. EF-2 damage was found in multiple locations in Todd County, while the strongest damage, rated EF-3, occurred in Clarksville, Tennessee. The tornado was on the ground for approximately 48 miles, 13 of which were in Todd County. A cold front had reached the Lower Ohio River around noon. CAPE values were approximately 1000 J/kg near the Tennessee border. Effective bulk shear was 60 kts, with 25-30 kts of surface-1km shear and ESRH of 200 m2/s2.

Event narrative: This tornado first touched down on Fort Campbell just north of the Sabre Airfield in Montgomery County, TN. The tornado tracked northeastward through northern Clarksville, entering into Todd County 5 miles west of Guthrie. As the tornado continued into southeastern Todd County, sparsely populated areas were affected initially. Hwys 41, 79, and 848 were blocked by debris or power lines and Hwy 181 was blocked by a train due to debris getting caught under the train. Trees were damaged, along with broken glass at a residence on the Dixie-Beeline Highway and destruction of an outbuilding on Old Railroad Lane. Large sections of a roof were removed from a home on Snardon Mill Rd. Much of the damage occurred on the south side of Allensville, where several homes had heavily damaged roofs, along with more trees, power poles, and outbuildings damaged or destroyed. The tornado continued into Logan County, KY, crossing over on the south side of Allensville. EF-2 damage indicators occurred repeatedly along the track throughout Todd County, suggesting a fairly consistent intensity for this segment. In total, hundreds of trees were snapped or uprooted and several power poles were broken. At least a dozen outbuildings were destroyed, including barns, sheds, workshops, and garages. Over a dozen homes suffered minor to major damage to roofs, siding, and gutters. Several homes had parts of roofs removed.

Event narrative: The tornado touched down south of Socastee Blvd between Everette St and Tyner St, snapping several large trees and blowing off portions of roofs from a few mobile homes. It moved north, skipped across Socastee Blvd, and snapped several large pines along Village Dr. Eight homes suffered moderate to major damage as a result of falling trees. The storm cell continued north across inaccessible property, and emerged near Folly Rd and Wayland Circle. Significant damage was observed to several homes and trees. Several trees were snapped or uprooted, and minor to moderate damage was noted to roofs and siding. One mobile home was pushed off its block foundation. The tornado appeared to lift as it crossed the Intracoastal Waterway and touched down again on the Arrowhead Country Club property. Numerous large hard and softwood trees were snapped just south of the Flintlake Apartments. Tree debris was blown into several apartments, breaking windows and causing moderate roof and siding damage. 

Damage upstream of the initial touchdown, along and south of  Palmetto Pointe Blvd, was straightline in nature and not the  result of a tornado. Additional wind damage occurred to the old  Waccamaw Mall at Fantasy Harbour. Portions of the facade were  blown off, in addition to several pieces of siding. A few bay  doors were blown in, and a large section of storefront wall was  buckled outward a few inches. A few nearby UPS and FedEx trucks were blown over, in addition to a tractor trailer. This damage  appeared to be the result of straightline winds that occurred  after the tornado dissipated and the storm cell bowed  northeastward. Spotty tree damage was also observed on the  northeast side of Highway 501 in the River Oaks area.
Episode narrative: A pre-frontal line of thunderstorms tracked eastward across Alabama around and just after midnight on December 10th. A segment of the line intensified over Jefferson County, producing two tornadoes and a large swath of wind damage. Elsewhere, two weak tornadoes were spawned over parts of southeast Central Alabama.

Event narrative: The National Weather Service surveyed in southwestern Lee County and found the damage was consistent with an EF0 tornado. The tornado initially touched down along County Road 30 where several trees were uprooted and a single family residence sustained minor damage. The tornado continued east-northeast crossing County Road 29 where additional trees were uprooted and a home had roof damage. It was also noted that a car window was blown out. The tornado then crossed County Road 11 just before lifting north of County Road 39. Additional soft and hard wood trees were damaged and uprooted along these two roads. It should be noted that this damage was adjacent to the EF4 tornado that impacted Lee County in 2019.
Episode narrative: A major tornado outbreak impacted Middle Tennessee during the afternoon and evening hours of December 9, 2023. With a surface low pressure system situated over the Great Lakes area, a cold front was oriented north-to-south from the Great Lakes southward into the southeastern United States. Ahead of this cold front, southerly flow advected plenty of moisture into Middle Tennessee as the atmosphere destabilized. Meanwhile, a potent low-level jet resulted in an abundant amount of wind shear. This helped to set the stage for organized thunderstorms with a tornado threat. Thunderstorms began to cross the Tennessee River into the mid-state during the early afternoon hours. The first tornado of the day touched down in Indian Mound in Stewart County. That same supercell spawned another, more significant, tornado in Montgomery County that impacted Clarksville. This was the strongest tornado of the event, causing EF-3 damage before it continued its path into Kentucky. In total, six tornadoes were confirmed from this event, including another long-track EF-2 tornado that impacted Davidson, Sumner, and Trousdale counties which was warned with a Tornado Emergency. Unfortunately, seven people were killed during this event.
