Two additional tornadoes have been confirmed from the storms on June 24, an EF0 in Owen county and an EF1 in Morgan county. Also, the path length of the Plainfield-Indianapolis tornado was extended by about 1/2 mile.

November 22, 1992 Tornado Outbreak
Today is the anniversary of the November 22, 1992 tornado outbreak. This outbreak spawned 15 tornadoes in central Indiana and is the largest November tornado outbreak on record here. Here is a writeup from the NWS in Indianapolis:

September 20, 2002 Tornadoes
Today marks the 9 year anniversary of the September 20, 2002 tornado outbreak. When we think about local tornado climatology, we don't tend to think of September as being an active month. The events of September 20, 2002 - and one tornado in particular - would turn climatology on its head.
The first of 6 tornadoes touched down in Posey county at 9:40 AM local time. It was on the ground for less than a quarter mile and caused no significant damage. The same thunderstorm would produce a stronger F2 tornado near Poseyville at 9:50 AM local time. This tornado destroyed 10 mobile homes and 4 other buildings and had a path length just under 5 miles.
After a break, another tornado would form in northwestern Pike county and move into Knox and Daviess counties. In Knox county, the tornado destroyed a few homes and damaged several others and peaked at F2 intensity. A conservation officer in his vehicle was thrown an eighth of a mile by the tornado. The tornado weakened to F0 as it moved into Daviess county, finally lifting after being on the ground for over 13 miles.
After another break in the action, the most notable tornado of the day touched down in Ellettsville at 12:59 PM local time and started producing F3 damage shortly thereafter. After weakening and heading northeast into Morgan county, the tornado reintensified and produced more F3 damage in Martinsville. The tornado remained at F2-F3 strength as it continued northeast into Johnson and Marion counties, producing additional F3 damage at Greenwood. The tornado took a slight left turn and entered the city of Indianapolis around 1:45 PM, generally producing F1-F2 damage on its trek through the southern and eastern portions of the city. The tornado exited Marion county just after 2 PM and continued northeast through several more counties, producing its final damage in Hartford City at 3:20 PM. In all, about 130 people were injured by this tornado with damage in excess of $150 million.
2 other tornadoes occurred simultaneous to the long track tornado. One of them damaged 10 single family homes and 30 mobile homes in Henry county and was rated F2. The other tornado destroyed 2 barns and 2 mobile homes in Rush county and was rated F0.
This event probably would've been forgettable were it not for the long-tracked F3 tornado. This tornado is interesting in several respects:
1) Its path length of 112 miles makes it one of the longest tracked tornadoes to ever hit the state (reanalysis of the April 3, 1974 Monticello tornado reduced the path length from 121 to 108 miles). The tornado was on the ground for a total of 2 hours and 21 minutes, giving it an average forward speed of about 48 miles per hour.
2) The tornado passed through 9 counties, second most behind the April 3, 1974 Monticello tornado
3) It is the second longest tornado to hit the United States in the month of September since 1950
4) The tornado did not occur as part of a discrete supercell; rather, it formed along a QLCS/squall line
5) Although the tornado was rain-wrapped much of the time and passed through urbanized areas, no deaths occurred

Top 10 Tornadoes Since 1950
#7 - September 20, 2002 Ellettsville to Hartford City Tornado
This is probably one of the lesser known tornadoes but that doesn't mean it wasn't impressive. It was on the ground for 2 hours and 21 minutes and traveled 112 miles and charged through the south and east side of Indianapolis. Fortunately, there were no fatalities but over 100 people were injured. This tornado was rated F3 and caused over $100 million in damage.

Biggest Summer Tornado Outbreaks Since 1950
Although tornadoes can and do occur here during Summer, they do not happen as frequently and tend to be weaker than those in Spring. This is mainly due to the fact that temperature gradients are less intense during Summer and thus the jet stream tends to be weaker and farther north. This lack of stronger winds aloft is detrimental to the production of strong tornadoes, but they can still occur when conditions come together just right.
I have scanned the tornado database back to 1950 in order to establish our biggest summertime tornado outbreaks. Here are some of the biggest outbreaks between the Summer Solstice and Autumn Equinox (roughly June 21-September 22).
June 26, 1973: 10 tornadoes struck the state, 9 of which occurred in central/southern Indiana. The strongest was a F2 near Bloomington.
July 30, 1992: 6 tornadoes occurred, including an F2 in Morgan county and a F3 in Johnson county. The Johnson county tornado had a path length of about 7 miles and injured 25 people.
September 20, 2002: 6 tornadoes happened with 4 of them rated F2 or higher. The highlight of this event was the long track F3 tornado that started near Ellettsville and ended near Hartford City in Blackford county. This impressive tornado had a path length of 112 miles, injured over 100 people and caused more than $100 million damage. For more on this event, click here
June 23, 2010: 6 tornadoes occurred in northern Indiana, mostly in Elkhart county. These tornadoes were spawned from a quasi-linear convective system which moved across the area.
August 9, 1969: 5 tornadoes occurred, the most significant being an early morning F3 in Indianapolis which injured 6 people.
September 19, 1988: 5 weak tornadoes struck various parts of the state, injuring 3 people.
July 26, 2005: 5 tornadoes occurred, including a F2 in Cass and Miami counties. Nobody was injured.
June 27, 2008: 5 brief EF0 tornadoes occurred, one of which injured 2 people in Morgan county.
Special mention: On July 9, 1980, a F4 tornado struck Rush county, killing 2 people. Although there was only one other tornado on this date (a weak F0 near Crawfordsville), this event is significant because it is the only known F4 tornado to hit Indiana during the summer.
