A Look Back, the Tornado Outbreak of August 24, 2016

Two years ago today, August 24, 2016, northern and central Indiana was impacted by 11 tornadoes.  Of the 11 tornadoes that touched down, 5 of them touched down in Howard County, including an EF-3 tornado that affected the southern portion of Kokomo.  The majority of this write up will be on that tornado that was 300 yards wide (nearly a quarter mile), had estimated winds of 152 mph and caused 20 injuries, but thankfully, no deaths.  We will look at the radar pictures as the tornado developed and moved across southern Kokomo, the warnings that were issued for this storm, the Convective Outlooks that were issued, and the pictures that were sent in to us, and brief look at the other tornadoes that touched down.

A combination of extreme low-level moisture and an upper-level disturbance moving through the area provided the trigger needed for showers and thunderstorms, despite the extensive cloud cover throughout the day.  By the early afternoon, there was just enough instability combined with high levels of shear in the lower levels of the atmosphere, lead to multiple tornadoes touching down.

The early Convective Outlook that was posted on August 24, showed much of Indiana under a marginal risk of severe weather for the afternoon hours.  Here’s what I posted at 4:33 am on that day…Good Wednesday morning, much of the state is under a marginal risk for severe storms, mainly during the late morning into the afternoon hours. Primary threat will be damaging winds. Showers and thunderstorms will increase from the late morning into the afternoon hours. In addition, heavy rainfall will be possible. We will monitor today and have additional updates as needed.

This was the first post from Equinox Weather on August 24, 2016 at 4:33 am…Good Wednesday morning, much of the state is under a marginal risk for severe storms, mainly during the late morning into the afternoon hours. Primary threat will be damaging winds. Showers and thunderstorms will increase from the late morning into the afternoon hours. In addition, heavy rainfall will be possible. We will monitor today and have additional updates as needed.

The morning and the early part of the afternoon hours was quiet, but around 2:30 pm, I would post the first of many radars that was showing signs of rotation and some that would eventually produce tornadoes.  The first radar post was at 2:30 pm for area of rotation that I noticed southwest of Crawfordsville and within 7 minutes, the first warning was issued by the National Weather Service Office in Indianapolis, here’s a look at a portion of that warning and the radar picture…

TORNADO WARNING FOR…
SOUTHWESTERN BOONE COUNTY IN CENTRAL INDIANA…
SOUTHEASTERN MONTGOMERY COUNTY IN WEST CENTRAL INDIANA…

* UNTIL 300 PM EDT

* AT 237 PM EDT…A SEVERE THUNDERSTORM CAPABLE OF PRODUCING A

The first of many tornado warnings that were issued on August 24, 2016

This storm would produce an EF-2 tornado that went through mainly open country, but did cause major damage to homes and barns near Linnsburg.  The path of the tornado was over 5 miles and tornado width of 125 yards.  This tornado caused no injuries or deaths.

The storm that would produce the EF-3 tornado became warned for the first time at 2:50 pm.  Here’s a look at portions of that warning from the Indy office…

TORNADO WARNING FOR…
SOUTHEASTERN CARROLL COUNTY IN NORTH CENTRAL INDIANA…
NORTHEASTERN CLINTON COUNTY IN CENTRAL INDIANA…
HOWARD COUNTY IN CENTRAL INDIANA…

* UNTIL 330 PM EDT

* AT 250 PM EDT…A SEVERE THUNDERSTORM CAPABLE OF PRODUCING A
TORNADO WAS LOCATED 12 MILES NORTHEAST OF FRANKFORT…MOVING EAST
AT 25 MPH.

The initial radar that I posted with this warning was at 2:52 pm.  You can see where the reds and the greens were next to each other, showing that rotation is present.  The rotation have not quite crossed into Howard County yet.  Then at 2:53 pm, I added the pathcast with the tornado warned storm, with the possible tornado arriving in Kokomo by 3:27 pm.

The first update on this tornado warning was at 2:59 pm, and the possible tornado was 10 miles west of Kokomo and moving east at 30 mph.  The next post was around 3:02 pm to show where the possible tornado was located with an updated pathcast.  This now showed the tornado to reach Kokomo by 3:22 pm.  Also the rotation was showing signs of getting stronger.  The tornado would touch down approximately 18 minutes later (more on that in a bit).

Aug 24 2016 1502

This was around the time of the first update of the tornado warning, when it was 10 miles west of Kokomo. The rotation was showing signs of getting stronger and the pathcast had the possible tornado reaching Kokomo by 3:22 pm.

The 3:09 pm update on the tornado warning stated that there was a confirmed tornado near Kokomo and moving east at 30 mph, though the official information from the National Weather Service would show the tornado touching down at 3:20 pm.  While the tornado may have been down at this point, the NWS team that surveyed the area may have not found a damage path.  The radar from 3:08 pm continued to show the rotation getting stronger.

Aug 24 2016 1508

Rotation on the possible tornado continues to get stronger and within a minute the updated warning suggests that the tornado may have touched down, even though the official reports states tornado did not touch down until 3:20 pm.

By 3:19 pm, behind the scenes, I was seeing that not only the tornado was likely on the ground, but may have been doing damage.  This was the update on the tornado warning issued at 3:17 pm by NWS…

AT 317 PM EDT…A CONFIRMED TORNADO WAS LOCATED OVER KOKOMO…MOVING

While at this point, it really didn’t matter how the radar looked like, we knew that a tornado is on the ground and it is causing major damage in southern Kokomo, but here is how the radar looked like, with a pathcast at 3:27 pm.  This tornado was projected to affect Greentown by 3:39 pm.

Aug 24 2016 1527

The highlighted warning that covered Kokomo was the area that was under the tornado emergency, as very strong rotation and tornado was over the southeast portion of Kokomo and causing major damage.

The updated tornado emergency warning at 3:32 was suggesting that a large and destructive tornado was on the east side of Kokomo.  Here is a portion of that update…

Then finally, some good news, by 3:36 pm, looks like that the rotation have greatly weaken the tornado may have even lifted and according to the official report, the tornado have lifted at 3:34 pm.  So the next two posts, will show that radar post, then the second will show the tornado track as plotted by the NWS.

Aug 24 2016 1536

It was during this time, the hook echo that normally associates with tornadoes was no longer showing and that the tornado may have even lifted, which official reports show that it did by 3:34 pm.

The tornado path suggests that there was two areas of EF-3 damage, the first near S. Armstrong St, and the second near and around Markland Mall.  Below is a series of damage photos that were submitted to us from the great folks of Kokomo and those who have sent them will be named in the captions and I apologize, I was not able to use all of them…

As it was earlier stated, this was not the only tornado of the day, as 11 tornadoes in total touched down across northern and central Indiana, including 5 all together in Howard County alone.  Below is a brief description of the other 9 tornadoes with credit from the National Weather Service Offices in Indianapolis and Northern Indiana.

Tornado breakdown from this outbreak was 5 EF-0s, 3 EF-1s, 1 EF-2s, and 2 EF-3s.  The 11 tornadoes that touched down were the most ever in the month of August, breaking the record of 8 tornadoes that occurred just 9 days earlier.  This outbreak also ties for the 11th largest in Indiana history.  Overall strong partnerships from the media, the EMAs, private meteorologists, storm chasers and spotters, and the National Weather Service offices in Indianapolis and Northern Indiana had kept people safe and very thankful that there were no loss of life.  While many people suffered property loss, you can always replace property, but you can never replace a life and that’s why we will continue to work very hard at Equinox Weather to provide watches and warnings during severe weather events.  For additional details on this outbreak you can check out details from the NWS Indy office, and the NWS Northern Indiana office.
