Episode narrative: Northern Ohio remained in a very humid air mass and along the northwestern flank of the Bermuda-Azores subtropical surface high pressure ridge during the late morning of the 28th into the 29th before a cold front swept southeastward across the region during the late morning through early afternoon of the 29th. Behind the front, a secondary trough axis moved generally southward across northern OH during the afternoon through early evening before another ridge built from the Canadian Prairies and northern Great Plains during the rest of the 29th. 

Ahead of the cold front, northern OH resided in an environment comprised of moderate to strong effective bulk shear and primarily moderate to strong MUCAPE. Along and ahead of the cold front, multiple rounds of multicell thunderstorms persisted generally eastward across northern OH. These storms produced sporadic straight-line convective wind damage in addition to a mesovortex-related tornado near Bucyrus, OH.

Event narrative: NWS storm survey found the path of a rare EF1 tornado over far northern Avery County. The tornado touched down just east of where Dark Ridge Rd crosses into Tennessee, where multiple large tree limbs were snapped. The damage path extended east/northeast into a heavily wooded area, re-emerging in the Whaley community, crossing Joe Parlier Rd and Beech Mountain Rd, before moving along Buckeye Rd. The most significant damage was observed in this area, with multiple small-to-medium size trees snapped and some larger trees uprooted. The damage path was lost near this point, as the tornado crossed into another heavily wooded area. It was determined that the tornado continued into Watauga County just south of Buckeye Rd, as additional damage was found in that county. This was only the second confirmed tornado in Avery County's history, with the other one having occurred on 9 April 1965.
Episode narrative: Strong shear supported multiple rotating thunderstorms across Northeastern Pennsylvania during the afternoon and evening hours.

Event narrative: A tornado touched down near the intersection of Mountain Road and  Stevens Point Road in Harmony Township northeast Susquehanna County  at 625 PM EDT Monday August 7th 2023. The tornado snapped and  uprooted many trees on Stevens Point Road as the tornado tracked  north-northeast roughly along Stevens Point Road. The tornado then  weakened as it crossed the PA - NY border with only some minor  tree damage along Laurel Lake Road in the Town of Sanford, Broome  County New York. The tornado then strengthened as it crossed over a hill and  hit Kenyon Hill Road. There was a residence on Kenyon Hill Road in  the Town of Sanford that bore the brunt of the damage with windows  blown out, shingles blown off the roof and numerous trees snapped  and uprooted. A shed was moved about 100 feet with a couple boats on  a pond lofted in the air. The tornado reached its maximum intensity  of 90 mph in this location before lifting over the next hillside.
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: An official from the Bankhead National Forest reported tornado damage to the National Weather Service (NWS) in a remote area. After reviewing high resolution satellite data through the United States Geological Survey (USGS), the NWS has determined an EF-1 tornado occurred. Damage indicators were mostly noted as hard wood tree uproots. Satellite imagery showed large swath of trees uprooted as evidenced by Worldview (35 cm) imagery. Tree fall patterns indicates convergence and falls partly perpendicular to storm track. Based on this information, the tornado touched down near Northwest Road and Thompson Creek and lifted near Braziel Creek.
Episode narrative: Strong thunderstorms developed along a cold front across the Central and Lower Great Lakes during the late evening and overnight hours of August 24-25, 2023. These thunderstorms were in an environment of strong to extreme instability, along with sufficient low-level and deep-layer wind shear for organized and rotating thunderstorms. This allowed storms that developed over Michigan to organize into a fast-moving cluster of thunderstorms that produced extensive wind damage and a number of tornadoes between southern Lower Michigan and southwestern Pennsylvania, and Ohio.

Event narrative: This survey found a concentrated area of extensive tree damage and sporadic minor structural damage that began on a farmland plateau northwest of Mill Run along Hampton Road, and continued southeast for approximately 2 miles, crossing Route 381, and ending along  Turkey Foot Road. This track cut across Yogi Bear's Jellystone  Park resort and campground, where several hundred campers were  present. A mixture of several hundred mature softwood and hardwood trees were snapped or uprooted across the campground, with many  landing on RVs, cabins, shelters, and other structures throughout  the campground. Several park fixtures including water slides,  wagons, and other unique damage indicators were also observed to  have sustained significant damage. Several tents were destroyed.  Three injuries are known to have occurred in the park from  falling trees.

The tornado then continued across Highway 381, producing additional damage to several tree groves and two farmsteads as  the tornado crossed Fairmont Road. Metal roofing was removed from several outbuildings, power poles were snapped, and a mobile home was rolled over a vehicle, landing on its side. Three additional  injuries were reported at these locations.

Drone footage was paramount in helping to document this tornado in a region of challenging terrain and limited roads, and was used  to help identify its beginning and ending points, as well as path width. The shear extent of tree damage within the Yogi Bear park  is consistent with an EF-2 rating and maximum wind speeds of  approximately 120 mph.
