The first outbreak occurred on November 6 affecting the Evansville, Indiana area, the deadliest since April 3, 1974. The second outbreak occurred on November 15 affecting the western Kentucky area. This outbreak included the nation’s strongest tornado for the year. November 6 Outbreak The deadliest tornado to strike Indiana since April 3, 1974 occurred around 2 a.m. on November 6. Twenty- four fatalities, 238 injuries, and nearly 90 million dollars in damage were inflicted by a single F3 tornado with a path length of 41 miles (below, right). A large mobile home park near the southern city limit of Evansville was the site of the vast majority of fatalities (bottom). Twenty of the 24 deaths were at the mobile home park. Three others, including a woman who was 8-months pregnant, died in a mobile home in neighboring Warrick County. One person died in a vehicle in Warrick County. Right: The F3 tornado traveled 41 miles in a northeasterly direction from just north of Smith Mills, Kentucky to Gentryville, Indiana. Below: Ground photo of the Eastbrooke Mobile Home Park after the street was cleared. The supercell thunderstorm which spawned the tornado developed over southeast Missouri. After crossing the Mississippi River, the thunderstorm continued to exhibit supercell characteristics as it tracked across southern Illinois, where isolated minor wind damage occurred. As the storm crossed the Ohio River into Henderson County, Kentucky, the rotation intensified and descended toward the ground. The tornado first touched down in agricultural bottomlands of the Ohio River several miles 4 west of Henderson (below, right). Even though the tornado passed between the urban centers of Evansville and Henderson, there were major casualties at a mobile home park and a horse-racing facility between the two cities. The tornado reached its peak intensity after entering Warrick County, Indiana, where a large number of homes and businesses were destroyed. In all, at least 500 homes and businesses were destroyed or severely damaged. The tornado dissipated as it crossed into Spencer County, Indiana.

The supercell thunderstorm which spawned the Evansville area tornado occurred within a broken line of thunderstorms. A few other cells in the line became supercells. Only one of these other supercells produced a tornado in the Paducah County Warning Area. The atmosphere became increasingly supportive of supercells during the several hours leading up to the event. A strengthening shortwave trough approaching from Missouri contributed to increasing wind fields and upper level diffluence in the near-storm environment. At the surface, a low pressure center located over northern Illinois, with a cold front trailing southwest across the Mid Mississippi Valley. Strong southerly low level flow advected surface dew points in the mid 60’s into the Lower Ohio Valley, resulting in sufficient instability for supercell convection. November 15 Outbreak On November 15, western Kentucky was at the heart of an outbreak of tornadoes, including the nation’s strongest tornado in 2005. The year’s strongest tornado struck the Madisonville, Kentucky area with F4 winds that injured dozens of people, destroyed 151 homes and businesses, and heavily damaged 67 others (shown on cover). Damage was estimated at 33 million dollars. Eyewitness accounts and damage patterns indicated the occurrence of multiple vortices near Earlington, where the most extreme damage was inflicted. Several houses were leveled in this area. See tornado map on the next page. 5 An F3 tornado tracked 44 miles across far western Kentucky, killing one person and injuring 20 others in Marshall County. The tornado was at its strongest in Marshall County, where the vast majority of the damage occurred. At a resort along Kentucky Lake, a campground and marina were destroyed (below, left), along with many boats and recreational vehicles. After crossing Kentucky Lake, the tornado left a swath of downed trees in the Land Between The Lakes National Recreation Area. The tornado then crossed Lake Barkley, struck a subdivision on the east shore of the lake, and lifted near I-24.

Although there were three lines of thunderstorms with embedded supercells, it was the second line during the mid afternoon hours that spawned the significant tornadoes. All of the convection occurred ahead of a cold front that trailed southwest from a deepening surface low. The low tracked from southwest Missouri during the early morning to northern Illinois by early evening. A very powerful mid level shortwave trough rotated northeast from the southern Plains into the mid and upper Mississippi Valley by evening. A 500 mb wind speed of 110 knots was reported in the evening Lincoln, Illinois upper air observation. Southerly low level winds increased to around 50 knots at 2,000 feet during the day, providing more than adequate shear, moisture, and instability for tornadic thunderstorms.
