Episode narrative: An upper-level shortwave trough moving east through the Central Plains initiated a few clusters of thunderstorms that spread into Mississippi during the morning of June 18th. With an unstable air mass and strong jet stream over the region, these storms became severe and produced hail and damaging wind through the morning. An additional round of severe storms developed during the evening of the 18th and into the morning of the 19th. This even resulted in a rare June tornado outbreak. The previous record for number of June tornadoes in the state of Mississippi was 7 in 1974. A total of 15 tornadoes occurred across the state from June 18-19, 2023 - making this event a record in its own right. The tornado which occurred near Louin, MS was the first F3 or EF-3 rated tornado in the state since 1957.

Event narrative: The tornado began northeast of the airport near the intersection of Gordon Road and Swanson Dr. Sporadic EF-0 tree damage occurred as it traveled east before intensifying to a low end EF-1 near Callaway Stadium on the LaGrange College campus. Roof damage occurred both to a local brewery and Georgia health department building. The most considerable damage occurred to a house near this location along Forrest Avenue where a large oak tree was uprooted and fell into the home. Several bleachers were tossed into a brick and metal fence destroying a portion of the fence. Damage continued to the northeast where numerous trees were uprooted and several homes sustained minor roof damage. Another area of EF-1 damage was observed at the George F. Harris Baseball Complex where a few trees were uprooted and several were snapped. The tornado then entered another area of homes where some tree damage and uprooted trees were noted before entering a shopping district along Highway 109 just west of I-85. Several businesses had damaged signs and minor roof damage. A local gas station had windows blown out of a car wash. Some additional damage continued to the northeast with some trees downed before the tornado lifted near the intersection of I-85 and Highway 109.
Episode narrative: A vigorous upper level trough traversed east through the Desert Southwest and into the Southern Rockies January 1st, before ejecting northeast across the Texas/Oklahoma Panhandles into Western Kansas on the 2nd. In advance of this trough, rich low level moisture quickly spread northward from the Gulf of Mexico across East Texas, North Louisiana, and Southern Arkansas, along a strong southerly low level jet that developed ahead of a deepening surface low over Southeast Colorado and Western Kansas. With the trough taking on a more negative tilt as it ejected northeast across the Panhandle region, a dryline mixed east to the I-35 corridor of North-central Texas by early evening, and into East Texas and Eastern Oklahoma during the evening and overnight hours. Large scale forcing increased well ahead of the approaching upper trough across the expanding moist sector from the late morning through the afternoon and evening hours of the 2nd, with scattered to numerous showers and thunderstorms developing across portions of Deep East Texas, North Louisiana, and Southern Arkansas. Increasing instability due to diurnal heating within a strongly sheared and moist air mass resulted in the gradual development of strong to severe thunderstorms across these areas, with locally heavy rain falling over areas where the storms moved repeatedly over the same areas. Rainfall amounts ranged from 1-3 inches across much of North Louisiana, with isolated higher totals of 5-6+ inches observed Eastern Bienville, much of Jackson, Western Ouachita, and Eastern Union Parishes. This resulted in areas of flash flooding across portions of North Louisiana from the mid-afternoon through the early morning hours on the 3rd, with sporadic reports of damaging winds and isolated tornadoes across the region as well.

Event narrative: An EF-0 tornado with estimated maximum winds near 70 mph briefly touched down near Ashland Road several miles northeast of the Edgefield community, where it downed large branches and peeled the shingles off of a roof of a gazebo. After crossing Ashland Road, the tornado peeled a metal covering off of a porch of a double-wide manufactured home and damaged the skirting around the home before it lifted.
Episode narrative: A major winter storm brought strong winds with moderate to heavy rain bringing renewed flooding of already elevated waterways. There was flooding of roadways, urban areas, rivers, streams and creeks, with rockslides and mudslides also reported. There were dangerous mountain travel conditions with snow levels around 4000 feet and 3 to 5 feet of storm total snowfall above 6000 feet.  Winds gusted up to 60-70 mph in the Central Valley. In the mountains there were gusts up to 80 to 115 mph, which coupled with heavy snow, brought whiteout conditions. There were widespread trees down across the area, blocking roads and causing numerous power outages. There were thunderstorms on the 10th with a tornado in Calaveras County and straight line wind damage and small hail reported in the northern San Joaquin Valley.

Event narrative: A brief EF-1 tornado touched down near a small reservoir and Hogan Dam Road and continued NE for approximately 0.4 miles. It caused extensive tree damage to white oak and pine trees with trees uprooted and topped. The approximate path length was 0.4 miles with a path width of 50 yards and max winds of 90 mph.
Episode narrative: Storms developed from the evening hours on the 15th and continued through the early morning hours on the 16th. Large hail, measured wind gusts above 60 mph and three tornadoes occurred during this event. 

This event had two areas of interest. Across the northeast counties, hit and miss thunderstorms popped up, and these were expected to intensify. Meanwhile, a line of storms arrived in the northwest (Ozark Mountains) from Oklahoma, and forecast models showed a weakening trend. In the end, the northeast storms did not amount to much, and storms in the northwest did not fall apart.

The northwest storms showed rotation at times on radar, and Tornado Warnings were issued. This was understandable as values of instability and shear (acquired through balloon launches/soundings) doubled in six hours (from 600 pm CST on the 15th to 1200 am CST on the 16th)! It was a scary situation because the warnings went out in the middle of the night while people were asleep. Three tornadoes were spawned, and tracked through portions of Marion, Newton, and Searcy Counties. The strongest of these (rated EF2) cut a swath from near Pindall (Searcy County) to a few miles southeast of Bruno (Marion County). A house on a hilltop (directly exposed to the wind) shifted off of its foundation and partially collapsed. Another home was heavily damaged (loss of roof and an outer wall), and part of a roof was removed from a third home. Barns and sheds were roughed up or destroyed, and trees were uprooted or snapped. At least a half dozen roads were blocked by tree debris including Highway 65 (which was closed temporarily). A couple of people suffered minor injuries.

The other two tornadoes (rated EF1) hit in and around Canaan (Searcy County) and along Highway 21 northeast of Fallsville (Newton County). Mainly tree damage was noted, especially with the latter tornado. Any structural damage was generally minor.

Other than the tornadoes, golf ball size hail was reported at Lurton (Newton County) and Ozone (Johnson County). A 62 mph gust was measured at Conway Regional Airport (Faulkner County).

Event narrative: This tornado touched down near Dakota Rd. and Highway 27. Along the path, trees were uprooted and snapped, , in addition to a roof removed from a small shed. The tornado appears to have dissipated at 225 am CST.
Episode narrative: A powerful winter storm brought heavy rain, heavy snow and strong winds to Southwestern California. Rainfall totals ranged from 2 to 5 inches across coastal and valleys areas with 4 to 10 inches across the foothills and mountains. Snow levels dropped down, resulting in significant snowfall across the mountains. Below 5000 feet, 6 to 12 inches of snow was reported while the resort level (greater than 6000 feet) received 2 to 5 feet of snowfall. With the snowfall and strong winds, a Blizzard Warning was issues for the mountains of Ventura and Los Angeles counties. As for winds, peak gusts of 60 to 80 MPH were reported.

Event narrative: Multiple reports of tree damage, associated with a non-supercell tornado, south of East Whitter. The tornado was very small and no injuries were reported.
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: National Weather Service meteorologists surveyed damage in western Elmore County and determined that it was consistent with an EF2 tornado, with maximum winds near 120 mph. The tornado began in a wooded area near the Autauga/Elmore County line, with snapped tree tops observed west of Highway 143. It tracked northeastward and began to intensify as it reached Coosa River Road and Foreman Road, where multiple hardwood trees were uprooted, a barn was damaged, and minor shingle damage occurred to residences. It continued to uproot trees, damage outbuildings, and remove shingles from homes as it crossed Highway 111 near Chase Drive and Toad Road. More hardwood trees were uprooted along Shady Nook Drive before it began to cross the Shoal Creek inlet of Jordan Lake. It remained over the lake for a little while and uprooted trees near the Lightwood Road bridge, some of which fell on residences. The tornado reached its maximum intensity as it reached the northeast side of Jordan Lake. Multiple residences on Circle Drive suffered roof damage with much of the roof removed from one residence. Many hardwood trees were snapped and some boathouses were destroyed. The tornado continued to move along the northeast shore of the lake uprooting trees, some of which fell on residences, and caused roof damage. Dozens of residences suffered varying levels of damage. The tornado exited the lake near Joe's Fish Camp Road, where several hardwood trees were uprooted. The tornado became progressively weaker while continuing to uproot a few trees, eventually dissipating northeast of Titus Road prior to reaching Highway 231.
Episode narrative: An upper level low moved into the Southern Plains during the evening of January 17th, before lifting northeast into the Central Plains during the daytime hours of the 18th. Warm, moist, and unstable air had spread north across East Texas, North Louisiana, and Southwest Arkansas during the 17th-18th, east of a surface low that ejected northeast from North Texas into Eastern Oklahoma. The instability was maximized by daytime heating across the extreme Eastern Texas, North Louisiana, and Southern Arkansas on the 18th, as large scale forcing ahead of the ejecting low increased across these areas from the mid-morning through the afternoon hours. This resulted in scattered to numerous strong to severe thunderstorms, with ample shear available ahead of an approaching cold front spawning an isolated tornado in Central Columbia County before these storms exited the region to the east during the afternoon.

Event narrative: An EF-1 tornado with estimated maximum winds near 100 mph touched down near County Road 52 near Lake Columbia. There, it snapped several softwood trees before continuing onward into forested areas where it caused intermittent damage. As the tornado continued to move northeast, damage was again observed near North Mill and North Cottage Street where trees were snapped and uprooted. The tornado continued on to uproot and snap trees as it crossed Washington and Neil Streets in the city of Waldo. Prior to reaching Highway 371, the tornado damaged an awning of a church, before knocking over several power poles and snapping trees across several blocks in Waldo. On the northeast side of the city limits, the tornado completely destroyed a small metal outbuilding and continued on to snap more trees at the edge of a farm before lifting.
