Event narrative: An NWS Storm Survey confirmed a tornado touched down in an open field south of W CR 400 N, between N CR 1000W and 925W. It tracked quickly northeast, flipping 8 spans of a center pivot irrigation system once, the destroyed 2 large pole barns at a residence near 400 N and 925W. Several trees were snapped and corn fodder from the field was pulled into the yard and extended northeast form there. The back garage portion of a home was damaged. Power poles were also snapped in the area. The tornado made a turn to the right some and began to weaken, striking a home at the intersection of W CR 400 N and N CR 900 N where the roof on the SW side of the home was lifted, several small er trees were uprooted and a fuel tank was rolled into the field to the NE. Debris was carried for a few more miles to the northeast. The track of the tornado may have continued further northeast but it weakened significantly after the noted damage areas. Max width 300 yards with max wind wind speed estimated at 100 mph.
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.

No structural damage was found. The largest concentration of damage occurred on CR 179 along and east of Boat Ramp Road. Several pines were snapped on either side of the highway and there were a couple of uprooted hardwood trees as well. The tornado then crossed a remote unpopulated area along Wright's Creek before damaging some trees on Bonifay Gritney Road between Dyson Circle and Faircloth Drive.

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.

Event narrative: This EF-2 tornado touched down north of C.M. Martin Road to the west of Highway 431 where it blew down a few trees. The tornado crossed Highway 431 south of Main Street where it knocked over some power poles, then continued to blow down trees east of the highway. The tornado moved into southern Springfield near Fairway Trail and Kemper Court, snapping and uprooting trees along many residential streets and causing minor damage to a few homes. More significant damage to homes occurred further northeast on Rudolph Street and Brentlawn Drive. The tornado strengthened as it crossed Highway 41 near the Kroger shopping center, with numerous businesses damaged from high-end EF1 to low-end EF2 intensity (110-115 mph). 25 vehicles in the Kroger parking lot were flipped with some thrown into nearby ditches. The tornado then crossed the railroad tracks behind Kroger and reached its peak intensity as it entered an industrial area, where multiple warehouse structures were heavily damaged. With the majority of these metal building systems having Grade 5 bolts holding down the columns, winds were estimated at EF-2/120 mph in this area. The tornado then struck a fire department and strip mall (EF-1/110 mph) and bent a steel transmission pole at a power substation (EF-2/115 mph) on the east side of the industrial park. As the tornado continued northeast, it significantly weakened but still uprooted trees and caused minor roof damage to homes on Greystone Drive and Sloan Lane. On Roy Pitt Road, the tornado destroyed a two car garage and rolled a trailer on its side (EF-1). The tornado continued to blow down trees as it moved northeast across Highway 76E near Oakland Road before finally lifting north of Sloan Road.
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.
