Tornado - Beech Bottom EF-1 Casey County Date 7/2/2023 Time (Local) 7:55 PM EDT EF Rating EF-1 Est. Peak Winds 105 MPH Path Length .12 Miles Max Width 40 Yards Injuries/Deaths 0 Summary: The National Weather Service conducted a storm survey of damage to a property off of Wilson Ridge Road. There a well-built home with a metal roof had its roof peeled off in the middle section of the home. In that same area, an attached back porch awning was also lifted and completely detached from the house. Some thick siding was removed from the home as well. Damage in this area was consistent with an EF-1 tornado with winds of 100-105 mph. The homeowner stated the damage occurred a little before eight o`clock, which is important given multiple storms moving across the area over that hour. Time that the tornado was on the ground was brief. Homeowner noted a small gap in the tree line north of the house which we believe was the starting point. Damage went downstream into a field of soybeans, but there was no apparent path in the soybeans themselves. We would like to thank the Casey County Emergency Management and Kentucky Emergency Management (Area 10) for their assistance with the survey.                                                                                   Track Map

Tornado - Anderson City EF-1 Anderson County Date 7/2/2023 Time (Local) 3:55 PM EDT EF Rating EF-1 Est. Peak Winds 100 MPH Path Length 3.57 Miles Max Width 400 Yards Injuries/Deaths 0 Summary:  Severe storms developed west of Lawrenceburg in two waves. One produced straight line winds as a squall line and moved from west to east into downtown Lawrenceburg where it caused multiple trees to fall, likely with winds of 80-90 mph. Additionally, a brick building downtown that had been previously damaged from the March 3rd event suffered additional damage to the brickwork. The other was a storm that developed just south of that line and caused a tornado to drop along Highway 44 west of Lawrenceburg starting in the 2200 block where several large trees had fallen along the road but had been cleaned up by the time the survey occurred. There was significant tree damage along McDonald Road paralleling Highway 44. The most significant damage occurred around a square home with pyramid shaped roof. Trees fell without hitting the home, but fell in multiple directions. No shingles were damaged, but that may be due to the steepness of the roof. The survey continued ENE with tree damage on both McDonald and Highway 44 from the 2200 block all they way to the 1600 block. At the latter location, a barndominium suffered partial roof damage. Part of the metal roof was torn in one slab and thrown to the east of the property. The property owner witnessed a circulation approaching and took shelter in an open garage whose closed doors were blown outwards. At this point the tornado appeared to lift, but additional damage was reported just downstream, along Hammonds Creek Rd, where several trees on a property were uprooted or snapped. The tornado appeared to lift beyond this point and merge with the main line heading towards Lawrenceburg. The National Weather Service would like to thank Anderson County Emergency Management for escorting us through the heaviest hit areas.                                      Track Map

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0 Weak 65-85 mph	EF1 Moderate 86-110 mph	EF2 Significant 111-135 mph	EF3 Severe 136-165 mph	EF4 Extreme 166-200 mph	EF5 Catastrophic 200+ mph

Radar Imagery

KLVX Base Reflectivity (left) and Velocity (right) at 3:04 p.m. EDT for a storm moving through Bullitt County. Radar estimated wind speeds just south of Shepherdsville are between 70-75 mph at approximately 700 feet off the ground. Widespread tree and power line damage was reported from this storm.	KLVX Base Reflectivity (left) and Storm Relative Motion (right) at 3:56 p.m. EDT for a storm moving through Anderson County. At this time, an EF-1 tornado was ongoing west of Lawrenceburg, with the tornado's approximate position being represented by the red box on the image above. Winds moving toward the radar (west) are represented by green colors, while winds moving away from the radar (east) are represented by red colors.	KLVX Base Reflectivity (left) and Velocity (right) at 4:31 p.m. EDT for a storm moving through the Lexington metro. The "reverse C"/"bowing" shape of these storms are a good indicator for strong or severe winds, and many reports of wind damage were received from Lexington and Fayette County around this time. While radar velocity estimates winds between 60-70 mph from this storm, the LVX radar beam is 5000-6000 feet off the ground over this area, making surface wind estimates less reliable.	KLVX Base Reflectivity (left) and Storm Relative Motion (right) at 7:55 p.m. EDT for a storm moving through Casey County. A very brief EF-1 tornado tracked just northwest of Liberty around this time, with the estimated position of the tornado being represented by a red box in the image above.

Environment

A strongly unstable airmass developed ahead of an approaching cold front on the afternoon and evening of Sunday July 2, 2023. In addition to the unstable atmosphere, strong shear for this time of year also developed, leading to the development of organized strong to severe storms. Some of the storms displayed supercell characteristics, including splitting supercells that veered to the right and left of the mean flow. 

Environmental Parameters - 3 PM EDT

Figure 1: Mean Sea Level Pressure A weak surface low was position over the lower Great Lakes region, with a trailing cold front entering the Ohio River Valley from the west.	Figure 2: 500mb Heights/Isotachs A shortwave trough was entering the region, providing an enhancement in the deep layer wind shear, as well as upward vertical motion (triggering) for thunderstorm development.	Figure 3: Surface Based CAPE 3000-4000 J/KG of surface based instability indicated a strongly unstable environment, capable of producing robust updrafts. Instability of this magnitude can lead to increase threats of large hail, damaging winds, and tornadoes in the presence of other critical environmental parameters.

Figure 4: Effective Bulk Shear This parameter shows the amount of available wind shear that the storm was able to ingest from the bottom to the top of the storm. Values over 25 to 30 knots are usually sufficient for organized severe storms, including supercells.	Figure 5: Downdraft CAPE Downdraft CAPE measures how much downward instability momentum a storm environment may have, which leads to increased damaging wind potential. In this case, values were well over 1000 J/KG which is very conducive to severe wind gusts from strong downdrafts.	Figure 6: Supercell Composite Parameter This parameter was showing the potential for updrafts to rotate, which is the main driver for the supercell storm mode. The combination of sufficient deep layer shear (speed and directional), combined with an unstable atmosphere created the potential for supercells.

The environment was very conducive to damaging winds, and instances of large hail with the strongest storms. However, the overall environment was not that favorable for tornadoes. In a couple of instances, local storm interactions and boundary ingestion likely contributed to brief enhanced tornado threats in Anderson and Casey counties.

Environmental Parameters - 7 PM EDT

Figure 7: Mean Sea Level Pressure A weak surface continues to be positioned over the lower Great Lakes region, with the cold front now having progressed south and east of the Ohio River.	Figure 8: 500mb Heights/Isotachs The shortwave trough continues to provide lift and enhanced deep layer shear across our region, allowing for continued support of organized strong to severe storms.	Figure 9: Surface Based CAPE The environment remains strongly unstable, however a weak low level inversion has begun to set up with the loss of daytime heating.

Figure 10: Effective Bulk Shear Plenty of deep layer wind shear still exists for organized storm updrafts, adding to the potential for severe weather, including supercell storm modes in this case.	Figure 11: Downdraft CAPE Downdraft CAPE remains strong south and east of the cold front. Damaging wind reports were continuing to occur where values were exceeding 1000 J/KG.	Figure 12: Supercell Composite Parameter As evidenced by other parameters, the environment was still favorable for supercells, including some left and right moving storms.
