What the National Weather Service wrote
The massive EF-4 that crossed southern Indiana finally lifted in Trimble County after a solid path length of 49 miles. This tornado crossed the Ohio River as an EF-1 with a 200 yard wide path length. It damaged a home and two barns on Roger's Road. The barns were overturned with several trees damaged in a manner consistent with 105 mph winds. The tornado then crossed a heavily wooded area near the intersection of Routes 625 and 1838 and damaged some garage shingles. At this point, a second satellite vortex developed just to the south of the main circulation. It totally destroyed a barn on Rodgers Road and extensively damaged another. It severely damaged a rugged forested area before merging with the path of the original tornado near the confluence of Corn Creek Road, Highway 625, and Joyce Mill Road. At this point, the tornado was rated an EF2 with 115 mph estimated winds. Three mobile homes near the intersection of Route 625 and Joyce Mill Road were destroyed along with extensive damage to power lines and poles. Farther east, trees were damaged near Rawlett Lane. Before lifting, the twister brought EF-1 damage to two homes and a mobile home on New Hope Ridge Road. It lifted around 2 miles west of Highway 421.
The wider storm
A surface Low over Missouri early in the afternoon of March 2nd strengthened to below 990mb as it moved north into Michigan by the evening hours. Around dawn, a warm front moved north of the Ohio River. Scattered strong storms developed along this front across northern Kentucky, bringing several reports of dime sized hail. By mid afternoon, the combination of strong wind shear, temperatures rising to the upper 70s and over 2000 Joules/kg of CAPE led to the development of numerous supercells. Several of these storms produced tornadoes not only in north central Kentucky, but later in the evening across eastern Kentucky. Large hail was common, with several reports of baseball sized hail that damaged automobiles and roofs.
Began near Trout (38.6333, -85.4328).
