Severe Storms For The Northeast U.S..; Heat And Fire Out West

A strong cold front will likely trigger severe thunderstorms and locally heavy rain on Friday from the Interior Northeast into the eastern Ohio Valley and northern Mid-Atlantic region, especially in New York state and Pennsylvania. Meanwhile, in addition to the ongoing heat wave in the West, fire weather concerns are increasing across the Great Basin into the Four Corners region. Read More >

Narrative:  One of the most devastating tornadoes to ever strike Kentucky.  This historic event may have actually started in Harrison County IN, but is traditionally plotted from west of Shively, Kentucky, in western Jefferson County.  The tornado moved north-northeast and northeast through the Parkland neighborhood (Twenty-eighth and Dumesnil), leveling a few homes.  This F4 damage was the only clear example of F4 strength winds along the path.  However, when the tornado entered the city of Louisville it was 200 yards wide and grew to 500 yards wide as it plowed through the central business district downtown.  Multi-story downtown buildings were hit by the tornado and subsequently collapsed.  At least 44 deaths occurred at the Falls City Hall (1124 West Market Street).  The building collapsed with 200 people inside; 75 at a lodge meeting on the upper floor and 125 children with their mothers taking dancing lessons on the lower floor.  This was one of the highest tornado death totals in a single building ever recorded in the United States.  Damage totalled $2.5 million (1890 dollars) in Jefferson County, with another half a million dollars with F2 intensity damage in Jeffersonville IN...along with 20 injuries.  The tornado then turned to the right and re-crossed the Ohio River, coming back into Louisville dissipating near the present-day intersection of Zorn Avenue and River Road after badly damaging the city water tower.  5 churches, 7 railroad depots, 2 public halls, 3 schools, 10 tobacco warehouses, 32 manufacturing plants and 532 dwellings were destroyed by the tornado.  Union Station was crushed as well.  The next morning the newspaper called the storm "the whirling tiger of the air".  The city organized crews of 60 men each who worked day and night searching the wreckage, along with families and friends. Sightseers started arriving the next day, and the Guard was called to control the crowds. The City refused any outside aid. The Board of Trade organized a relief committee to oversee the recovery, and the Board also authorized $15,000 in pensions to widows and orphans of the storm.

Time:  3:08pm
Narrative:  One of the worst tornadoes in Kentuckiana's history.  This large tornado passed one mile north of Corydon as it moved east across central Harrison County.  Many farm buildings were damaged, and one farm was almost completely blown away.  Its occupant was found in a ditch 200 feet from the foundation, unconscious, critically injured, and holding her unharmed baby. The twister moved east-northeast from three miles west of New Albany and cut a swath of death and destruction through the north side of town.  Damage totaled $1,500,000 as 500 homes were destroyed, along with two schools and many other buildings.  While many homes were swept away, the deaths were concentrated in groups, including at least five (possibly 12) deaths at the Olden Street School, eight deaths at a wood specialties plant, and five deaths in one home.  Some children were killed on their way home from school.  The tornado dissipated after striking Harrod's Creek, Kentucky.
Note: Grazulis counts this as two tornadoes, with a gap in the path at the Harrison/Floyd County line. More recent research by Gary Purlee and Cody Moore indicate that this was actually one tornado.

Grazulis narrative:  Moved east-northeast and northeast from three miles south of Huffman, passing southeast of Branchville, north of Sulphur Springs and Pilot Knob, south of Sulphur and Curby, across the southeast part of DePauw, hitting two miles east of Palmyra, passing through Martinsburg, crossing the southeast half of Daisy Hill, passing between Bunker Hill and New Liberty, and ending two miles north of IN 160.  This tornado immediately killed a woman as it destroyed her mobile home.  As the tornado passed along southeast of Branchville it killed again.  Two people, riding in a school bus, saw the tornado and took shelter in a nearby ditch.  The bus was thrown fifty feet into the ditch, crushing the couple and killing the woman.  Moving across Crawford County, the tornado widened to over a mile, missing many small communities and levelling several farms.  In Harrison County the tornado killed a woman in her mobile home in southeast Depauw.  Another woman was killed in her home two miles east of Palmyra.  In the southeastern corner of Washington County the tornado struck the town of Martinsburg, destroying 38 of the town's 48 homes.  Homes in the Daisy Hill area were completely swept away.
Noted discrepancies:  SPC and Grazulis list 6 deaths for this tornado, NCDC lists 5.  SPC lists 86 injuries, NCDC 53, Grazulis 76, Storm Data 95.  SPC lists a path length of 68 miles, NCDC 50 miles, Grazulis 62 miles, Storm Data 67 miles.  SPC gives a path width of 10 yards (obviously incorrect), NCDC 30 yards (obviously incorrect), Grazulis 1760 yards, Storm Data 700 yards.  This tornado is split into two tornadoes at SPC.  Grazulis lists an incorrect ending point for the tornado.  Storm Data begins this tornado between Huffman and Tarry in Perry County and lifts it a few miles northeast of Lexington in Scott County.  SPC lat/lon ends the tornado southwest of Lexington, rather than northeast.  It's been mapped here according to the information in Storm Data, but additional research would be helpful.

Notes:  Washington County:  
The National Weather Service in conjunction with Washington County Emergency Management conducted a detailed tornado damage survey on Saturday, March 3. Below are the results.

The tornado first touched down on the south side of Fredericksburg just south of U.S. 150 where several trees were snapped off. In this area, winds were estimated to be 90 mph (EF1) with a damage width of 30 yards along the south fork of the Blue Lick River.

Additional tree damage was observed as the tornado moved east- northeast across farmland. Near the intersection of Horners Chapel Road and Fredericksburg Road, a high tension metal power structure was toppled along with numerous trees uprooted and snapped. Here, damage was estimated as EF2 with 130 mph winds. Along Palmyra Road near Strickland Road, several trees were snapped with EF1 damage 50-100 yards wide and estimated winds of 100-110 mph. High tension wires were down and trees snapped along West End Road just north of Shanks Hill Road.

The tornado then traveled over a ridge and intensified as it hit State Route 135 at Dutch Creek Road. Here, large chunks of 5- or 6-inch thick asphalt from an approximately 4-by-4-yard  section of roadway were blown 10 to 30 yards into the adjacent  grass next to the road. Just east of Route 135, tremendous tree  damage was observed. At this location, the tornado was estimated to be of EF3 strength with 150 mph winds. The width of the damage  path also began to widen, increasing to 200 yards.

Tree and structural damage was widespread northeast of Route 135 as the tornado crossed Trainer Lane and then State Road 335 to Robbs Lane. The width of observable damage increased to one-quarter to one-third of a mile. Countless trees were snapped and uprooted. The degree of damage suggested a mix of EF2 and EF3 damage in this area, with estimated winds of 120-150 mph.

The tornado crossed U.S. 60 just south of New Pekin. Immediately east of the highway, tremendous structural damage was observed. A well-constructed and large factory building (Airgo Industries) was cleared to its foundation slab with numerous anchoring bolts bent in the direction of the storm. Debris from this building was observed one-half to three-quarters of a mile downwind. Large power poles were snapped. Another metal out building on the right periphery of the damage path had sheeting pulled off the back of the building apparently from the force of the inbound winds into the tornado. This was the area where 5 people were tragically killed in a mobile home. In this location just east of U.S. 60, damage suggested an EF4 tornado with 170 mph estimated winds, and a width of observed damage from 0.3-0.4 mile.

Damage continued to the east along and south of Hurst Road in extreme southeast Washington County. The tornado crossed into extreme northwest Clark County along and near Daisy Hill Road. In this area, a well-constructed one-story brick house at the top of a small ridge was completely destroyed with no walls standing. People onsite reported that cows were missing and could not be located. They also stated that the tornado looked like a black wall as it approached. A heavy trailer cab was blown from this house to another demolished brick home about one-quarter mile away. Damage here suggested EF4 damage with 170 mph winds.

As the tornado re-entered Washington County near the intersection of Daisy Hill Road and Williams Knob Road, widespread damage occurred. This included a home which was totally leveled as well as a couple of anchored down double wide trailers. A car was destroyed and tossed about 100 yards in the direction of storm motion from its origin at the home. At one of the destroyed trailers, a Dodge Ram pickup truck was tossed onto its side and destroyed in the opposite direction from the car (i.e., on the left side of the tornado track). Here, EF3-EF4 damage was estimated with winds of 150-170 mph. There were also snapped trees and structural damage along Whiskey Run Road. The width of the observed damage straddling the Washington-Clark County line was estimated to be one-third to one-half mile wide, although the width of the most concentrated damage was narrower. The last observed damage in Washington County was near S. Flatwood Road in a wooded area before the tornado entered Clark County.

Across Washington County, particularly east of IN 135, thousands of trees were uprooted and snapped.

Clark County and Scott County:  The National Weather Service in conjunction with Clark County Emergency Management conducted an exhaustive tornado damage survey on Saturday and Sunday, March 3 and 4. Below are the results. The tornado continued east-northeast in far northwest Clark County on Dan Gray Road where the twister leveled many well-built homes and caused extensive tree damage. The tornado here was rated EF4 with estimated wind speeds of 170 mph and a damage width of one-third mile.

The tornado moved into far southeast Washington County before reappearing in Clark County. In Clark, the damage width narrowed to one-quarter mile as the tornado crossed Pixley Knob Road and decreased in intensity to EF2 with wind speeds of 115-120 mph.

Farther east, the tornado intensified again as it destroyed two double wide homes on Speith Road. One family residence on the west side of the road was severely damaged, reflecting EF3 damage with 150 mph winds.

The tornado crossed Interstate 65, damaging several vehicles and semis and closing the interstate for several hours. Several people were trapped in these vehicles, but were later rescued.

The tornado continued to strengthen just east of Exit 19 of Interstate 65 in a heavily industrialized area. Here, buildings containing several businesses were severely damaged. A home was destroyed on the east side of North Fraucke Road. The violent tornado also seriously damaged several homes on the north side of State Highway 160. Here, there was evidence of multi-vortex structure with EF4 damage and 175 mph estimated winds.

The tornado then struck the south buildings of the Henryville middle and high school complex, with severe damage and 170 mph winds (EF4). The middle school experienced the worst damage. The cafeteria was completely destroyed. Two school buses were ripped off their chassis.

There was also extensive structural damage on the east side of Henryville on North Front Street and Pennsylvania Street. A high tension tower and other homes were damaged on Pine Drive. Incredible tree damage also occurred just west of Pine Drive as the tornado traveled up a ridge. In this region, the tornado was an EF3 with 150 mph winds.

On Brownstown Road, many homes were severely damaged especially on the north side of the tornado track with estimated speeds of 150 mph (EF3). Farther east, there was massive deforestation on the east side of a ridge just west of and along Henryville Otisco Road. Several more homes were severely damaged along this road. One of these homes reflected EF4 damage and 170 mph winds.

The tornado rapidly narrowed to a rope-like structure and ended as an EF1 with 90-95 mph winds and an 80 yard wide path. This occurred near the intersection of Blackberry Trail and State Highway 3.

Simultaneously, a new cyclic tornado vortex rapidly formed from the same supercell near Mahan Road and Old State Road 3 immediately southwest of the first tornado. The second tornado began as an EF1 and damaged a church and a few trees. The vortex quickly intensified to EF3 strength as it crossed the south portion of the town of Marysville, severely damaging several homes.

East of Marysville, another cyclic vortex from the parent storm formed just southwest of the intersection of Nabb New Washington Road and Nabb Marysville Road. This vortex intensified and merged with the primary circulation. The tornado severely damaged or destroyed several houses and double wide mobile homes around the intersection of Nabb New Washington and Nabb Marysville. Debris from the double wides was tossed around a mile downwind. The tornado was rated EF3 here with 150 mph winds and a damage width of one-third mile.

A Civil Air Patrol flight on Sunday, March 4 revealed extensive ground scouring in farmers` fields east of Marysville all the way to the Jefferson-Scott County line. This scouring was evidence of a multi-vortex tornado, which was confirmed by multiple videos and photographs.

The tornado continued north of Barnes Road, damaging several clusters of trees in open country. The tornado intensified east of the intersection of Kettle Bottom and State Highway 362.

In Scott County, immediately north of Highway 362 and east of Concord Road, three homes were severely damaged while five double wide mobile homes were completely destroyed. Here, the tornado was an EF4 with 170 mph winds. Just south of 362 in Clark County, two additional homes and power poles were damaged greatly. From there, the tornado crossed into Jefferson County, Indiana.

Jefferson County:  The National Weather Service in conjunction with Jefferson County, IN Emergency Management conducted the tornado damage survey in Jefferson County. The tornado traveled from Clark County, Indiana across extreme southeast Scott County and into far southern Jefferson County. Damage was observed along and just north of State Highway 362 near the 3-county line. This included several mobile homes totally destroyed, several framed houses heavily damaged, tremendous tree damage, and power poles snapped and shredded. The observed damage width was one-third of a mile with estimated winds of 170 mph (EF4).

The tornado traveled east-northeast snapping trees and power poles on County Road 850, and did its most significant damage at the intersection of Jackson Road, State Highway 62, and Swan Road about 2 miles south of the town of Chelsea.

In this area, several well-built brick homes were destroyed. The homes had anchor bolts attached to steel plates and a concrete foundation. One house was lifted and slid 65 yards off its foundation while mostly still intact. Another home was completely demolished and thrown downwind several hundred yards, within which there were 3 fatalities. The garage of this house was destroyed with one vehicle thrown 30 yards and another tossed 75 yards. A piece of farm equipment was thrown 200 yards as well. A third well-built brick home had its roof completely lifted and thrown over 300 yards downwind. Also, an above ground pool half filled with water was missing. Wind speeds in the area were estimated at 170-175 mph (EF4) with a damage width of one-quarter mile.

The tornado tracked to the north of Paynesville and south of Lee Bottom, extensively damaging forests in southern Jefferson County before crossing the Ohio River into Trimble County, Kentucky. The damage width narrowed in this area to only a couple hundred yards.

Trimble County:  The National Weather Service in conjunction with Trimble County Emergency Management conducted an extensive tornado survey in Trimble County.  The tornado crossed the Ohio River from Jefferson County, Indiana and narrowed to about 200 yards wide.  The tornado damaged a home on Rodgers Road, overturned two barns, and uprooted and/or twisted several trees.  This was consistent with EF1 damage and 105-110mph estimated winds.

At the same time a second vortex formed immediately adjacent to the first vortex and totally destroyed a barn on Rodgers Road and extensively damaged another.  This tornado also damaged a lot of rugged forested area before intersecting with the path of the first vortex near the confluence of Highway 1838 (Corn Creek Road, Highway 625, and Joyce Mill Road.  In this area the tornado was rated as an EF2 with 115 mph estimated winds.

Three single-wide mobile homes near the intersection of Joyce Mill Road and Highway 625 were destroyed along with tree damage and downed power lines and poles.  This was consistent with EF1 damage, 105 mph estimated winds, and a damage width of 75 yards.

No evidence of further damage was observed until Rawlett Lane, where some trees were snapped and uprooted.  There could have been damage in-between although the survey team was unable to access this area.  The tornado then struck two homes and a single-wide mobile home on New Hope Ridge Road (Highway 2870) about 1.5 miles west of Highway 421.  Here EF1 damage, 90 mph winds, and a path width of 50 yards were estimated.  The tornado lifted near this location.

Path width:  60 yards
Path length:  6.5 miles (skipping)
Time:  3:30pm EST
Notes:  Photographs taken during a Civil Air Patrol flight corroborate interviews with residents along the damage path that there were intermittent touchdowns of a weaker tornado with the second supercell to pass over the area (see previous tornado).  The second storm, which pummeled the recently devastated area with hail up to the size of softballs, followed nearly the same path as the first supercell. At least three locations along the path of this storm support the occurrence of a tornado of EF-1 intensity, with maximum winds approaching 110 mph, an intermittent path length of 6.5 miles, and a damage path width of 60 yards.  The first observed damage was near Round Knob in the Clark State Forest. Damage was again observed along and west of Speith Road, 1/4 of a mile north of Henryville-Blue Lick Road just southwest of Henryville. Finally, the tornado lifted after doing damage from the south side of Henryville near Robyn Avenue to the east side of Henryville at the intersection of Highway 160 and Haddox Road.

Notes: A small tornado touched down in the back yard of a home about a quarter mile west of the caution light on IN 60 in Borden and uprooted trees and caused roof damage to the home. The tornado moved along Muddy Fork and snapped or uprooted numerous trees. The tornado then crossed IN 60 where people in the Buckboard Diner witnessed it. The tornado next removed the roof of an older building next to the cafe and a garage behind the cafe. It threw the debris into a small church and removed some of its roof.
