What happened

The episode as NWS LOT wrote it up.

Severe thunderstorms moved across northwest Indiana during the afternoon and evening of June 11th producing wind damage, localized flooding and several tornadoes.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Chicago, IL wrote its last area forecast discussion before the first event at Jun 11, 1:42 PM CST, 13 minutes earlier. Its key messages:

  • Severe storms likely through this evening (highest threat between 5 and 10 PM). All hazards (tornadoes, destructive winds, significant hail) are possible across the entire area.
  • After a dry and cooler day on Friday, there is another threat for severe weather late Saturday.

.MESOSCALE...
Issued at 222 PM CDT Thu Jun 11 2026

Quick update on latest thinking regarding today's severe threat.
The 18z sounding from ILX has shown an impressive EML (elevated
mixed layer) has advected into the area. This is resulting in
MUCH steeper 700-400 mb lapse rates, however at the base of those
steeper lapse rates there's been about a 2C+ warming in/near
700mb. That warming near 700mb and resultant convection
inhibition combined with weaker large scale ascent (for now) has
prevented the convection near the tail end of the morning MCS from
becoming rooted in the boundary layer and taking off. This bodes
well for reducing the chances for discrete convection in the open
warm sector across central IL.

HRRR continues to lose that convection much more quickly than
what is actually happening, however the WOFS (Warn-on Forecast
System) hangs onto that convection and the lingering footprint
of the cold pool longer than the HRRR. It too, loses that
convection quickly, perhaps a bit too quickly, but generally
depicts that the northern extent of the very concerning tornado
environment later this afternoon would be a farther south. It
wouldn't be shocking to see that northern extent shift a bit
farther south in later runs as WOFS initializes from current
radar.

Farther west, the low level response the sfc cyclone lifting
northeast has been quite impressive with northward surge of low
level moisture. Cloud cover and precipitation is preventing
boundary layer temps from warming in this area resulting in very
weak low level lapse rates. Farther south, across far northeast
Missouri some breaks in the cloud cover have allowed temps to warm
into the low to mid 80s, resulting stronger low level CAPE.
Satellite trends suggest that some partial clearing will
overspread much of northern IL this afternoon. This combined
with increasing southerly flow in the synoptic response to the
deepening low lifting north in Iowa should result in the
outflow boundary/southern extent of outflow from the morning
convection gradually lifting north and perhaps mixing out a bit
this afternoon.

It still seems like there will be a gradient between stronger
low level CAPE and weaker low level destabilization somewhere in
our CWA. Latest WOFS has the northern extent of that better low
instability and resultant very favorable tornado environment
getting as far north as roughly to an Ottawa to Chicago line by
later this afternoon. While the exactly how far north the more
concerning environment gets is lower confidence (ultimately may
not be a sharp line rather more of a gradient), but the general
idea of significant tornado threat increasing near/south of I-55
and I-80 seems reasonable.

There is a dramatic increase in low and deep layer shear comparing
ILX's VWP to DVN's VWP. The unseasonably strong shear noted on
DVN's VWP is expected to spread eastward across our CWA as the
afternoon progresses. Storm mode may tend to favor linear by the
time the convection reaches our CWA, but given the very strong low
level shear, QLCS tornadoes and perhaps even tornadic supercells
embedded within the QLCS will be a threat. This threat will likely
be more prolific where the stronger boundary layer heating leads
to stronger low level CAPE, but even farther north the strong
shear will support a QLCS tornado threat.

Finally, any discrete supercell within the warm sector later this
afternoon (especially southern CWA) will be in an exceptionally
favorable environment for strong tornadoes. While linear storm
mode is most likely, there is still some chance for discrete
supercell development in the warm sector, so we will be
watching that closely. If the remnant outflow boundary from
this morning's MCS doesn't mix out, then it would be a potential
source for enhanced low level vorticity and a zone we'd watch
for a locally higher tornado threat (both supercellular and
QLCS).

.DISCUSSION...
Issued at 242 PM CDT Thu Jun 11 2026

Broad mid and upper-level cyclonic flow will persist across the
northern United States through the period. While this will
maintain periodic opportunities for showers and thunderstorms
into next week, we will experience a brief break in pattern for
Friday. On Friday, a much less humid airmass shifting overhead
on westerly winds in the wake of this evenings cold frontal
passage will support a more comfortable weather day with
temperatures topping out around 80 under mainly sunny skies.

Humidity values will be back on the increase again for Saturday
as the low-level flow turns south-southwesterly in advance of
the next approaching surface cold front dropping southward from
the Upper Midwest. As the front shifts into our area late
Saturday into Saturday night, a narrow corridor of slightly
better low-level moisture return preceding it may support the
development of some scattered showers and thunderstorms. Should
these materialize, we will also have to monitor the potential
for some more organized storms into Saturday evening,
particularly given the presence of strong deep layer flow. While
not looking to be a major severe weather event at this time, we
certainly cannot rule out the threat for a few stronger storms
to become capable of producing instances of damaging winds and
hail. Accordingly, the SPC Day 3 outlook continues to highlight
our area in a level 1 of 5 severe weather threat for late
Saturday.

A push of much cooler and dry weather is anticipated for the
second half of the weekend into early next week following the
cold frontal passage Saturday night. Interestingly, this airmass
looks to hold daytime highs in the 70s (lows in the low to mid
50s) early next week. Conditions then look to turn more active
again (return of showers and thunderstorms) mid to late next
week as an enhanced northwesterly upper-level flow pattern sets
up across the central part of the country.

.AVIATION /18Z TAFS THROUGH 00Z SATURDAY/...
Issued at 1250 PM CDT Thu Jun 11 2026

Key messages for the 18Z TAF period:

* Showers and non-severe thunderstorms to begin the period with
  gusty westerly winds possible

* Additional strong to severe thunderstorms in the mid-afternoon
  to early evening. Strong to damaging wind gusts, hail, and
  LIFR vsbys will be possible

The period opens up with a push of showers and non-severe
thunderstorms moving east across the Chicago metro. Gusty W
winds to around 30 kt and pockets of moderate to heavy rain can
be expected through around 19Z with additional showers
lingering. Storms have moved past RFD at the time of this
writing and will see largely shower activity through mid-
afternoon.

A push of strong to severe thunderstorms will roll across N IL
from the west from mid-afternoon through early evening. Storms
look to approach RFD after 21Z and the Chicago sites after 23Z.
Widespread strong to damaging wind gusts are the primary concern
from a TAF perspective, although instances of severe hail and
tornadoes will also be possible with these storms. Heavy to
torrential rainfall should bring vsbys down to at least IFR with
LIFR likely for a brief period. The severe threat should last
on the order of an hour or less over any given location with
additional showers and storms trailing into the mid-evening.

Outside of thunderstorm winds, WSW winds will back around to
SSE for mid-afternoon behind this first push of storms. Winds
will then abruptly turn westerly with the arrival of the
stronger storms and remain westerly into Friday. Gusts to 20 to
25 kt following the storms will persist into the night.
