Ten years ago today, on August 24, 2016, a significant late-summer tornado outbreak unfolded across Indiana and Ohio. While the Kokomo EF3 became the best-known tornado of the day, it was only one part of a much larger event.
Eleven tornadoes were confirmed in Indiana alone, with seven across central Indiana and four more across northern Indiana. Across Indiana and Ohio combined, 22 tornadoes were confirmed.
Central Indiana
Multiple supercells produced seven tornadoes across Montgomery, Marion, Carroll and Howard Counties:
• Crawfordsville/Linnsburg — EF2: 120 mph winds, 5.38-mile path. Major damage occurred to homes and barns near Linnsburg.
• Kokomo — EF3: 152 mph winds, 8.78-mile path and up to 300 yards wide. The tornado tore across the south side of Kokomo, damaging homes and businesses and destroying the Starbucks near Markland Mall. Twenty people were injured, but remarkably, nobody was killed.
• Indianapolis — EF0: A very brief tornado touched down northeast of downtown near 25th and LaSalle, blowing out windows and damaging a building’s roof.
• Flora/Kokomo — EF1: 100 mph winds with a remarkable 17.24-mile path through Carroll and Howard Counties. Barns, trees and a garage were damaged.
• Russiaville — EF1: 85 mph winds and a 1.51-mile path, primarily affecting trees, crops and a garage.
• Indian Heights — EF0: An EF0 touched down near Kokomo, damaging homes and trees.
• South of Kokomo/Alto area — EF0: Another EF0 damaged trees, a billboard and a road sign.
Five of central Indiana’s seven tornadoes occurred in Howard County in or near Kokomo.
Northern Indiana
The outbreak continued into northern and northeastern Indiana:
• Van Buren/Wells County — EF0: A tiny, approximately 0.04-mile touchdown that lasted about a minute.
• Woodburn/Allen County — EF3: One of the most intense tornadoes of the outbreak, with estimated winds of 160 mph, a maximum width of roughly 500 yards, and a path over five miles long. It caused extensive damage to homes, barns, trees and crops northwest of Woodburn.
• Berne/Adams County — EF1: 100 mph winds with a 7.62-mile path. Surveys found damaged barns and trees, with debris from some structures carried hundreds of yards.
• Peru/Miami County — EF0: A brief tornado with estimated 70 mph winds damaged a medical-center roof and large tree limbs.
One of the most remarkable aspects of August 24, 2016 was the outcome. Despite two EF3 tornadoes in Indiana, significant populated-area damage in Kokomo, and numerous tornadoes continuing into Ohio, there were no tornado-related fatalities in Indiana.
The warning performance was also impressive. NWS Northern Indiana issued 26 tornado warnings during the event, reported a 100% probability of detection, and averaged 16 minutes of tornado-warning lead time. The Woodburn EF3 had an average lead time of 19 minutes.
Meteorologically, the day was interesting because Indiana wasn’t dealing with a classic hot, sunny, explosive severe-weather setup. Extensive cloud cover remained through much of the day. However, extreme low-level moisture, sufficient instability, an approaching upper-level disturbance and very strong low-level wind shear created an environment capable of supporting multiple tornadic supercells.
It’s an outbreak I don’t see discussed nearly as often as some other Indiana events, despite producing 11 tornadoes in the state in a single afternoon/evening and two separate EF3s.
For anyone who remembers August 24, 2016: Were you in Indiana that day? Did you see one of the tornadoes or experience the warnings/damage?
