NWS Confirms Tornado In Marion County
NWS Indianapolis has confirmed a brief tornado touched down on Saturday evening in Indianapolis, just northwest of downtown. This tornado occurred in association with the remnants of Hurricane Isaac. The tornado was captured on a tower camera with the touchdown occurring near 16th Street and the White River. No damage has been reported or observed, but it is likely that this tornado will be rated EF0, and the yearly statistics on the right reflect this assumption.

2011 Year In Review
As we move toward the end of 2011, I thought it would be prudent to post a summary of this year's tornadoes. Here it is month by month.
February:
6 tornadoes occurred, all of them on the last day of the month. An EF2 tornado cut a 14 mile swath in Dubois county, injuring 1 person. A separate EF2 struck portions of Gibson and Pike counties.
April:
This was a quiet month for tornadoes until the 19th. 29 tornadoes struck the state on the 19th and into the 20th, the second most in a single outbreak. This event was followed up on the 23rd by an EF0 tornado in Jackson county. Three additional tornadoes struck the state on the 26th and 27th, one of them an EF2 which had a 5 mile path through Warrick county. There were 33 tornadoes in total during April, making it our second most active month on record.
May:
May followed a similar trend as April with a quiet early and middle part of the month. Then an EF1 tornado in Jasper county kicked things off on May 22. EF0 tornadoes struck Huntington and Ripley and Dearborn counties on the 23rd. After a 1 day break, another significant outbreak happened on May 25. This outbreak produced 22 tornadoes, including several EF2's and an EF3 in Lawrence county. The Lawrence county tornado began east of Bedford and moved northeast for about 7 miles before lifting. In all, there were 25 tornadoes in May.
June:
Like the preceding months, much of June was quiet. The first tornado was a brief EF0 in Perry county on the 19th. Another tornado struck Harrison county on the 22nd. Two more tornadoes occurred during the early morning hours of the 26th, bringing the monthly total to 4.
July:
Only 1 tornado happened in July, a brief EF0 in Newton county on the 23rd.
September:
After nearly 2 months without a tornado, an EF1 hit Jennings county early on the 26th. An EF0 struck Elkhart county the following day.
November:
An EF1 tornado touched down in Orange county on the 14th, the only tornado during November. This was the last tornado of the year, bringing the 2011 total to 72.
February:
6 tornadoes occurred, all of them on the last day of the month. An EF2 tornado cut a 14 mile swath in Dubois county, injuring 1 person. A separate EF2 struck portions of Gibson and Pike counties.

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

September 12, 1988 Indianapolis Tornado
Still waiting for the May Storm Data to come in so the May tornado statistics can be finalized. Hopefully this occurs sometime in the next couple weeks.
Anyway, since posts have been lacking as of late, I thought I'd mention that today is the anniversary of a F1 tornado that hit Indianapolis. The tornado began on the north side of the city and moved northeast through Marion, Hamilton and Madison counties. Roofs and automobiles were reportedly damaged along the path. The tornado caused intermittent damage over a path length of about 35 miles and resulted in 1 injury.
