Event narrative: National Weather Service meteorologists surveyed damage in northwest Winston County and determined that it was consistent with an EF1 tornado, with maximum winds near 100 mph. This tornado began in Marion County and crossed into Winston County just north of Sherwood Place Drive. The tornado weakened somewhat as it crossed the county line, and the damage path widened. As it approached the vicinity of Posey Field, the tornado seemed to intensify locally, uprooting several trees in a residential neighborhood. The tornado crossed Airport Road, damaging trees and a detached garage at a residence. The tornado continued eastward through the Center community, with damage decreasing and becoming more sporadic before eventually dissipating just north of County Road 68 just west of Alabama Highway 195.
Episode narrative: Numerous strong to severe thunderstorms impacted Central Alabama during the morning and afternoon hours of Thursday, January 12th, 2023. Several supercell thunderstorms spawned multiple tornadoes which caused significant damage in many areas. The severe thunderstorms also produced damaging straight-line winds and hail up to golf ball size.

Event narrative: National Weather Service meteorologists surveyed damage in southeast Greene County and determined that it was consistent with an EF1 tornado, with maximum winds near 90 mph. This tornado crossed a winding Black Warrior River several times before eventually moving into Hale County. Damage consisted of several uprooted and snapped trees along the river banks.
Episode narrative: A very strong system developed on the morning of March 31st and tracked across the state of Iowa. This system pulled unseasonably warm and moist air into the Midwest, which combined with a very favorable wind profile to create a volatile environment for severe thunderstorms.  Discrete supercell thunderstorms occurred initially, but quickly transitioned into a QLCS mode. This system produced a historic tornado outbreak for the area, with a record 29 tornadoes on the day, including 13 rated EF-2, 1 rated EF-3, and 1 rated EF-4. This was the first EF-4 tornado in the NWS Quad Cities service area since 1995. 11 injuries were reported, with no known fatalities. In addition to the numerous tornadoes, there were many large hail and damaging wind reports. Maximum straight line thunderstorm winds were estimated at 80 to 90 mph.

Event narrative: A tornado touched down just south of Bellevue, and moved northeast over the Mississippi River before dissipating. This tornado impacted an RV park and some cabins located nearby. Some structural damage was noted, with some RVs that were flipped and damaged. Several trees within the area were also impacted, with some uprooted. Three  injuries were noted with this tornado in the vicinity of the RV park. This tornado continued into Jo Daviess County, Illinois, but likely dissipated over the river as no damage was observed in a wooded area adjacent to the river. Peak winds were estimated around 105 mph. The tornado damage in Bellevue was rated EF-1. The rating in Jo Daviess County was EF-U as there was no observable damage.
Episode narrative: A cold front moved into northwest Ohio the evening of Thursday, June 15. A weak surface low pressure developed along this front over southern Michigan earlier in the day and moved southeast across the western tip of Lake Erie during the evening. A warm front extended southeast of this low pressure along the western Lake Erie shoreline and then down towards central Ohio. Thunderstorms erupted along the cold front near Toledo just before 6:00 PM and moved southeast towards east-central Ohio over the coming hours. Enhanced vertical wind shear associated with the low pressure and warm front allowed storms to rotate amidst an unstable environment. A particularly intense supercell (rotating thunderstorm) developed near the Ohio/Michigan border just north of Toledo and tracked across parts of Lucas, Ottawa, Sandusky, Erie, Huron, Seneca, Richland, Ashland, and Wayne Counties. This supercell was responsible for nine tornadoes and numerous instances of large hail, with hail to at least the size of tennis balls reported near Toledo and multiple reports of hail to golf ball sized or larger as the storm continued southeast. Heavy rainfall from this supercell also produced flash flooding across Huron County. Storms gradually congealed into a line that produced some hail and straight-line convective wind damage into east central Ohio.

Episode narrative: Abundant moisture, relatively weak air flow, and a weak disturbance moving through the region produced scattered thunderstorms during the afternoon and evening of June 10.

Event narrative: A brief landspout developed around 1.5 miles west-southwest of Lake Wilson, and was seen and photographed by numerous individuals, despite its brief appearance.  The touchdown occurred within an open field and caused no visible damage to determine a rating.
Episode narrative: A stalled front remains situated just to the northwest this morning with a light onshore flow near the surface while persistent southwesterly flow continues aloft. Cooler than normal mid-level temperatures created deeper instability that strengthened diurnally driven sea breeze storms as they develop along the east-coast sea breeze in the afternoon. Deeper moisture was across NE FL and portions of SE GA (generally south and east of Waycross) created more widespread storm coverage, especially along and west of the St Johns River basin as the sea breeze interacted with the river breeze. 

Strong to marginally severe wind gusts of 40-60 mph occurred. Marginal deep layer shear was around 20 kts which create a lower end hail threat. Locally heavy rainfall occurred that created mainly nuisance minor flood issues.

Episode narrative: A surface low moved across north-Florida during the early morning hours as a warm front lifted up from central FL. Strong effective shear combined with marginal surface-based instability near the lifting warm front and surface low enabled rotating mini-supercells to form. Toward sunrise, enough low-level instability nosed inland from the Atlantic coast across Flagler County to support a couple of tornado touchdowns. Locally heavy rainfall occurred across northeast Florida, generally south of the I-10 corridor and toward the Atlantic coast.
