What happened

The episode as NWS LOT wrote it up.

July 28th saw two rounds of severe storms move across the Chicago metro, one during the predawn hours of the morning and another during the evening. The first round brought isolated instances of damaging wind to the area and the second featured damaging winds, severe hail, and 13 tornadoes across the WFO Chicago CWA: 11 in Illinois and 2 in Indiana. Additionally, temperatures in the 90s and high humidity resulted in oppressively hot conditions with afternoon heat indices as high as 105-115 F.

.UPDATE...
Issued at 816 PM CDT Thu Jul 27 2023

We are in a bit of a holding pattern this evening as we monitor
convective trends well to the N/NW and a mid-level wave in Iowa.
Both are in play for convection developing very late this evening
through daybreak.

A benign wave with generally warming cloud tops and very little
remaining mid-level reflectivity over the east half of Iowa
continues to drift east this evening, with a couple more embedded
subtle mid-level curls from Dubuque to Iowa City and west toward
Des Moines. Meanwhile, a WNW to ESE boundary well-defined along a
decent theta-e gradient is gradually lifting north across the far
southern CWA. A few attempts of convective initiation have been
observed along this boundary for the past several hours, but a
substantial layer of mid-level dry air evident per the 00Z KILX
RAOB and regional WV imagery have suppressed most activity in the
absence of more formidable forcing. Weak low-level isentropic
ascent will begin to align ahead of the approaching wave late this
evening beneath steep low to mid-level lapse rates. So while
saturation of LPL heights sufficient for more robust deep
convection remains in question, expectations are that some
isolated to scattered elevated storm activity may begin as early
as prior to midnight near the far western CWA. A gradually
eastward shift in activity is then expected by around daybreak
across the east half of the CWA as the parent wave exits east.
Modest effective shear of 20-25 knots combined with weak diurnal
stability and a reservoir of deeper drier air with DCAPE values
over 1000 J/kg will support locally damaging winds. Isolated
instances of large hail also cannot be ruled out.

Upstream convective trends in MN/WI are becoming more favorable
for a more robust cold pool to surge well south into the early
morning hours and perhaps reach the IL/WI state line by the 2-4am
window. This outflow could enhance any ongoing slightly elevated
convection with the wave to the west, reinforcing any stronger
outflow winds extending through northeast Illinois prior to
daybreak.

No additional changes were made beyond daybreak ahead of an
additional round of potentially severe convection late Friday
afternoon and evening. See the short-term discussion for more
details during this period.

.SHORT TERM...
Issued at 340 PM CDT Thu Jul 27 2023

Through Friday night...

Key Forecast Messages:

* Chance of thunderstorms overnight tonight-early Friday with a
  level 1 severe threat and localized flash flooding threat

* Oppressive heat and humidity away from Lake Michigan shore
  (especially IL shore) until cold front passage late Friday

* Thunderstorms developing near a southward sagging cold front
  late Friday afternoon through Friday evening with an associated
  level 2 of 5 severe threat (primarily damaging winds and hail)
  and a level 2 of 4 flash flooding threat

...Thunderstorms and Associated Severe and Flooding Threats:

Highly uncertain convective forecast through tonight. A weakening
MCV and decaying convective footprint across central Iowa will
encounter a very dry mid-level air mass and strongly capped
conditions locally this evening. For now, no explicit precip.
mention for this, and would appear that at most spotty showers
clipping areas west of I-39 this evening.

Turning attention to overnight, strong to severe thunderstorms
have initiated across the Upper MS Valley/far northern Great Lakes
region near the cold front that will play a role in our weather
tomorrow. CAM solutions have ranged from little/no elevated
convection into our area, though outflow effects from the north,
to a strong/severe southeastward moving MCS and various
scenarios between these extremes. The global guidance,
particularly the ECMWF, has been quite consistent with a footprint
of storms in our area tonight. Continued with chance PoPs given
the uncertainty, highest I-80 and north, between roughly 1 AM and
6 AM, possibly hanging on as late as 7am-8am hour eastern CWA.

It's unclear if upglide from strengthening low level jet will
result in elevated convection blossoming in addition to upstream
convection moving in, and certainly can't rule out the "null"
scenario either. Conceptually an MCS would ride the thickness and
instability gradient southeast into the area, and mid-level lapse
rates will be steepening. On the other hand, there may be
lingering capping issues to elevated parcels from antecedent dry
air aloft and very warm EML base, plus effective bulk shear is
forecast to be on the marginal side at 25-35 kt. SPC included us
in a level 1 (marginal) risk for damaging winds, which appears
reasonable, and high PWAT regime could support pockets of heavy
rain/localized flooding *if* deep moist convection is widespread
enough. These next few to several hours well off to the northwest
will *hopefully* shed some light on how things will go.

Confidence is increasing that regardless of a decent overnight
convective footprint, extreme warmth at the 850 mb level should
cap things off and the balance of Friday will be dry. The steep
mid-level lapse rates, dew points pooling well into the 70s south
of southward sagging cold front, and temps into the 90s are
expected to contribute to very large (up to 3-4k J/kg MLCAPE).
Questions remain on exact timing of convective initiation, ranging
from mid-late afternoon across far northern Illinois to holding
off until the evening. MLCIN should erode with time and modest
height falls plus backdoor front shifting south late in the day
Friday point toward a decent chance of explosive convection
starting over far northern IL and then gradually expanding south
into or through the evening. This has been a scenario consistently
depicted by the ECMWF over recent days.

We'll message a timing of 4pm-12am roughly for what will be a
fairly classic mid-summer severe and flooding threat. Sufficient
deep layer bulk shear up to 35-40 kt and large instability plus
steep low and mid-level lapse rates support damaging wind and hail
threats, with uncertainty regarding mode (surging bowing segments,
or more loosely organized clusters. Proximity of the cold front
boundary likely slowing its southward progress with inland extent
suggests that a brief tornado or two near the boundary can't be
ruled out amidst favorable low-level CAPE. Finally, PWATs up to
2-2.25", basically top of the charts even for late July, and
likelihood of intense convection suggests pockets of excessive
rainfall are plausible, particularly if west-east training occurs
north of the sagging front and any outflows. For the reasons
above, collaborated with WPC for a level 2 (slight) risk in the
day 2 ERO. SPC maintained its level 2 of 5 (slight) severe risk in
its day 2 update, which is reasonable due to the overall
uncertainty in convective evolution.

...Oppressive Heat and Humidity:

No big changes in the thinking for the heat and high dew point
forecast, with main update to add northern and central Cook
(including Chicago) into the Heat Advisory on Friday. Thinking
most locales away from the lake will top out in the low-mid 90s,
with widespread mid 70s dew points common outside of the heart of
the Chicago urban heat island. Upper 70s to even 80F dew points
are a decent bet due to ET over farming areas. The extreme 100+F
temp scenarios appear to be strongly driven by over-mixing and
mixing out dew points well below what is likely to occur, though
ultimately ends up a wash when the oppressive dew points still
yield 105-110F to locally 115F degree heat index values, highest
southwest half of the CWA where no changes were made to the
Excessive Heat Warning.

As mentioned above, did add in northern and central Cook zones
into the advisory for Friday, but note that models have come into
better agreement on an earlier onshore wind shift prior to the
backdoor front arrival in the afternoon. This would entail Lake
County IL seeing onshore winds all day and the Chicago shore
seeing an earlier onshore wind shift and muting the heat there
somewhat. Given this, did not include Lake County IL in the
advisory and Heat Advisory text mentions inland of Lake Michigan
being in line for the peak heat indices near 105 degrees and we
did brief the city of Chicago on this element.

While debris clouds and stronger onshore winds may conceivably
start the day with north and eastward extent, the earlier
overnight convective timing (albeit with plenty of uncertainty)
and very potent air mass (mid 20s C at 850 mb) point toward us
being able to realize the forecast heat indices on Friday.

.LONG TERM...
Issued at 108 AM CDT Fri Jul 28 2023

Saturday night through Thursday...

After a hot and stormy end of the week, the long-term period looks
relatively quiet as upper-level troughing stalls over the Great
Lakes. The result should be lowering humidity levels and
comparatively cooler temperatures with highs in the low to mid 80s,
save for even cooler readings (mid to upper 70s) along the Lake
Michigan shoreline. We'll have to keep an eye on the potential for
choppy waves and rip currents on Lake Michigan beaches on Sunday.
The next chance of rain looks to arrive toward the end of the
workweek.

.AVIATION...
For the 06Z TAFs...

The aviation forecast has much lower than average confidence owing
to the possibility for multiple rounds of convection including subsequent
impacts on winds. For this reason, opted to maintain the
structure and themes of the inherited TAFs with only modest
adjustment to timing of wind shifts and convection.

A weak wave continues to move across northern Illinois ahead of a
southward-moving outflow boundary from Wisconsin. As the outflow
boundary catches up to the wave across northern IL, at least
isolated to scattered thunderstorm development remains possible
primarily between 07-12Z. Based on the observed speed of the
approaching outflow boundary to the north, opted to move up the
timing of a north to northeasterly wind shift and VCTS at each
terminal. If coverage of convection is trending higher, will
introduce targeted TEMPOs at each terminal but for now will
continue a "wait and see" approach. Notwithstanding variable
directions in and around convection, winds behind the outflow
boundary should turn northerly with gusts of 15-20 kt before
"going around the clock" from northeasterly to easterly and
eventually southwesterly by daybreak.

Convection or not before daybreak, there remains a signal in
available model guidance that the mid-morning to early-afternoon
period tomorrow should be dry (but we offer no guarantees given
the unstable and moist environment). Nevertheless, southwesterly winds
should become gusty (15-25kt) in the afternoon as mixing peaks
with diurnal heating.

Attention then turns toward the potential for another round of
convection tomorrow evening. While the exact evolution and
character of convection is not overly clear at this range, the
overlap of seasonably strong upper-level flow, orientation of a
surface boundary and developing westerly low-level jet, and
copious amounts of instability warrants concern for a potentially
prolonged period (6+ hours) of convection near of over the
terminals. In addition, convection may be associated with damaging
hail and winds, including gusts >50kt. For now, opted to
introduce 6 hour VCTS groups and push back the inherited TEMPO
groups keeping in mind adjustments are all but likely in future
TAF packages. As always, wind directions in and around convection
may be erratic and variable.

This tornado began just west of 8000 East Road at 2500 North Road west of Momence, based upon drone imagery provided by the Kankakee County Emergency Management Agency. The tornado produced EF-0 damage to a farm near the aforementioned intersection with damage to tree branches and part of a metal outbuilding roof damaged. The tornado continued east just south of 2500 North Road with a narrow, convergent path evident in a corn field from drone imagery. The tornado's intensity briefly weakened in the immediate vicinity of the Kankakee River with only limited tree damage noted. Just east of River South Road, the tornado again intensified as it moved through fields toward IL-17. Drone footage again indicated a narrow path of convergent damage in corn fields until the tornado moved into the backyards of a few residences on River South Road, causing significant damage to multiple trees. As the tornado moved east, drone footage revealed additional corn flattened in the field southwest of the Van Drunen Farms building. The tornado then struck a row of two-story apartment homes on Harvard Street, removing the roof and a portion of the upper-level walls from one of them and depositing the debris over the next couple of blocks to the east. Damage to the adjacent apartment homes was very minor. East of Harvard Street, there was little to no additional structural damage, but there was considerable damage to trees and power lines, especially along Indiana Street. East of Momence, the tornado continued along Route 114. Just west of N 13250E Road, it removed part of the roof of a metal outbuilding while snapping and uprooting additional trees.
