Unrated tornado, Jasper County, Indiana, August 12, 2026

This Unrated tornado ran 0.4 miles across Jasper County on August 12, 2026, touching down at 10:49 AM CDT and reaching 50 yards wide. It killed nobody.

Preliminary. This is NWS LOT's damage survey, filed in the Damage Assessment Toolkit as Rensselaer. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the survey found

A narrow tornadic damage path through crops was observed in Sentinel-2 satellite imagery just east of Rensselaer. The damage path was a little over 0.4 miles long and about 50 yards wide. Since this tornado did not cause any known damage to any qualified damage indicators, it has been assigned an EF-U rating.

Written by NWS LOT in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

The damage survey

2 damage points were recorded along this path by NWS LOT, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU.

  • Approximate start point of narrow damage path through crops in Sentinel-2 satellite imagery.
  • Approximate location of last instance of crop damage evident in Sentinel-2 satellite imagery.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

.DISCUSSION...
Issued at 329 AM CDT Wed Aug 12 2026

Forecast remains complex within our persistent pattern of active
weather. Main concern in the near term is the potential for
another fast-moving line of wind-producing storms across at
least a portion of the area later this morning/midday.

A nearly stationary frontal boundary remains in place across
the Midwest early this morning, stretching roughly from near
Omaha to north of Des Moines to Milwaukee. Complicating the
surface pattern however, is the remnant outflow boundary from
Tuesday's derecho, which intersects the front near Waterloo, IA
and extends southeast and bisects IL along a SQI-BMI-MTO-EVV
line. The west/northwest periphery of the cold pool appears to
be fairly shallow however, per 00Z DVN and ILX soundings (as
compared to ILM farther to the east/southeast). Aloft, a subtle
mid-level short wave has been evident in GOES vapor imagery
transiting northern IA and entering northwest IL, inducing a
modest west-southwest 25-30 kt low level jet from northern MO
into northern/central IL/IN. With an axis of 3500-4000 J/kg
MUCAPE along/north of the front/outflow boundary across the
region, there's been concern since last evening for the
potential to develop elevated convection within a northwest-
southeast arc across the area (along/northeast of the remnant
outflow boundary). So far however, only isolated updraft
attempts have been noted and successive CAM runs have backed off
considerably in convective coverage across the forecast area
through daybreak. That said, we'll have to continue to monitor
for any deeper updraft development, as the environment would
support the potential for strong elevated storms with a hail
threat if they develop.

Of greater concern this morning, is an MCS which has been
developing southeast from western South Dakota into northern
Nebraska overnight in association with an attendant mid-level
short wave and MCV. There is notable CAM support indicating this
MCS becoming more organized across eastern NE/western IA toward
daybreak, then propagating quickly eastward along the
aforementioned surface front/outflow boundaries into our IL cwa
after 14/15Z (9-10 AM) this morning. While not quite as robust
as yesterday's derecho, high-res guidance does explicitly
indicate 60-70 mph winds across parts of our forecast area with
this MCS. CAMs indicate an easterly propagation of this system
across the cwa, though with the remnant outflow likely mixing
back north across the southern half of our cwa that may support
more of an east-southeast or southeast track as we saw
yesterday. SPC has pulled their new Day 1 slight (level 2 of 5)
severe risk up to about a Dixon-Renssalear line. It's possible
that could be adjusted further if the evolution of the MCS
supports it later this morning. For now, will be advertising the
severe threat (primarily wind) even a little north of that for
this morning/midday. Thunderstorm threat should then diminish
markedly from the west into this afternoon in the wake of the
MCS and parent short wave.

There may be somewhat of a lull in convection
coverage/potential tonight into early Thursday morning,
depending on the footprint of the anticipated MCS cold pool, and
with some weak mid-level height rises indicated in model
guidance. Have trimmed pops during this period especially up
north along the IL/WI border and Lake Michigan. Another mid-
level wave (currently over NV/UT) is then progged move into the
region on Thursday which look to increase shower and
thunderstorm chances again during the day and with additional
rounds through at least Thursday night. These continued rounds
of storms will maintain at least a marginal severe threat and
a threat of flash flooding if storms train over the same areas.

Unfortunately, medium-range guidance continues to depict our
active pattern remaining in place across the region into the
weekend. There does appear to be decent agreement in the global
models/ensembles that high pressure eventually settles across
the western Lakes region by Monday-Tuesday of next week, pushing
our stalled frontal zone to the south and providing a period of
dry weather at that time.

.AVIATION /12Z TAFS THROUGH 18Z THURSDAY/...
Issued at 719 AM CDT Wed Aug 12 2026

Key Messages:

- A complex of storms is likely to affect the terminals between
  mid-morning and mid-afternoon today. Strong to severe wind
  gusts will be possible with these storms.

- IFR/LIFR ceilings and visibilities possible at RFD this
  morning, while patchy MVFR ceilings remain possible elsewhere.
  Additional low ceilings and reduced visibilities possible
  overnight tonight into Thursday morning.

An organized thunderstorm complex is entering northern Illinois
early this morning and will approach the terminals during the
mid-late morning. Some uncertainty remains with whether these
storm complex will begin to dive southeastward along an
instability gradient or whether it will continue to progress
more towards the east and into the heart of the Chicago metro.
Current thinking is that the strongest winds with this storm
complex (50+ kts) may remain south of the terminals, but the
threat for lightning at the Chicago metro terminals remains high
enough to maintain the going TEMPO groups. Also maintained a
VCTS mention at RFD, but the latest radar trends that the storms
should remain south of RFD. Conditions are likely to dry out by
mid-afternoon.

IFR/LIFR ceilings and some visibility reductions are being
observed at/near RFD this morning, while patchy MVFR ceilings
are being observed elsewhere at press time. These conditions may
stick around for a bit this morning, but a return to prevailing
VFR conditions is favored by this afternoon. Persisting rich
low-level moisture and light winds may allow for another
episode of sub-VFR ceilings and visibilities late tonight into
tomorrow morning. The potential for this appears to be greatest
at RFD, DPA, and GYY, but based on how some forecast guidance
fared poorly with the visibility and low ceiling forecast this
morning, confidence in this occurring is only low-medium.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
