The episode as NWS LOT wrote it up.
A strong cold front moved across northern Illinois during the late morning and early afternoon of November 5th with convective showers which produced thunderstorm wind damage and one tornado. Wind damage from the convection was described as countywide across Ogle, Boone and McHenry Counties. DuPage Airport measured a peak wind gust to 77 mph. A handheld anemometer measured a wind gust to 80 mph near Roselle.
High winds caused tree damage both in the early morning of November 5th and then again in the afternoon of November 5th. A large portion of a roof was blown off an apartment building in Elk Grove Village. Some trees fell onto vehicles in Chicago. Peak wind gusts included 62 mph at DuPage Airport; 61 mph at Aurora Municipal Airport; 59 mph at Chicago Midway and Chicago Executive Airports and 58 mph at Waukegan Airport.

.SHORT TERM...
Issued at 250 AM CDT Sat Nov 5 2022
Through Sunday...
...Strong Fall System to Impact our Area Today...
The main forecast points are as follows:
* Strong winds remain on track today. Gusts will increase rapidly
at sunrise and last through sunset.
* Confidence has increased in a period of damaging wind gusts (>60
mph) this morning generally along and east Interstate 55 where a
High Wind Warning is now in effect. Elsewhere, gusts are
expected to remain between 45-55 mph as covered by a Wind
Advisory.
* With strong winds lasting through much of the day, downed tree
limbs and scattered power outages appear likely especially within
and in close proximity to the High Wind Warning.
* Arcs of showers will continue to move through the area with
drying expected by early afternoon. Severe weather currently
appears unlikely (<2%) along the cold front owing to little to
no instability.
* Conditions will improve quickly after sunset with weakening
winds and clearing skies.
Discussion:
Regional satellite imagery, observations, and surface analyses
confirm a surface low pressure system currently in central Missouri
is in the process of rapidly deepening as a sharpening upper-
level trough passes overhead. Recent high resolution model data
suggest the system will drop some 10-12 mb in the next 8 hours
while lifting toward La Crosse, WI. In response to continued
pressure falls in the Great Lakes, a low-level jet is in the
process of rapidly intensifying directly over our heads as
confirmed by recent VWP scans from both KLOT/KILX displaying 50kt+
at 1000-2000 feet and 70-80-kt at 4000-5000 feet. In fact,
surface wind gusts already hit 40 to 45 mph across the Chicago
area before showers began, which is impressive considering the
time of day. Speaking of showers, the intense WAA regime will
continue to support a band of showers across the region through
sunrise. As a testament to the strength of the rapidly deepening
low pressure system, narrow convective elements that originally
developed near the AR/MO border yesterday evening continue to
survive within the messy stratiform regime now entering central
Illinois. A sharp back edge to the showers is present in far
western Illinois, and will progress eastward over the next few
hours.
High resolution model guidance is in agreement that the southerly LLJ
will peak between sunrise and noon with 850mb flow of 70-75kt
(80+mph), right as the showers are pushing east into Michigan.
Accordingly, there now appears to be a window of opportunity to
mix into the base of the intense low-level jet before the cold
front sweeps across the area toward noon. Such a threat appears
highest along and east of Interstate 55, and is highlighted in
recent iterations of both high resolution and global guidance with
nearly ubiquitous depictions of 50-55 kt (60+ mph) wind gusts for
several hours this morning. In addition, the 51-member EPS mean
peak wind gusts range between 55 and 60 mph along and east of
I-55, with several individual members producing local gusts of
nearly 70 mph. For these reasons, we opted to upgrade a portion of
the Wind Advisory to a High Wind Warning where confidence has
increased in warning-level impacts of numerous downed trees and
power outages. It must be stressed that winds will increase
abruptly at sunrise, going from simply breezy within the rain to
strong enough to down tree limbs.
The cold front will sweep across the area between 10 am and noon,
ushering in a modest wind shift toward the southwest. Anytime one
finds themselves within the warm sector of a rapidly deepening low
pressure system, they must watch out for surprise severe weather
events anytime of day and even with meager instability. High
resolution model guidance continues to advocate for a strongly force
band of showers along the cold front, which may locally augment wind
gusts. Given the literal bare-bones meager CAPE expected,
convective updrafts along the front will likely be of limited width
and strength. With this in mind, updrafts may very well get
ripped apart as they grow upward, limiting their overall
longevity and "sucking" power. As a result, the threat for a
surprise tornado event along the front appears to be low (<2%). If
more instability develops to sustain low-level updrafts than
currently expected, the threat for tornadoes would increase.
Sometimes, we can't tell whether we have enough instability until,
well, tornadoes start developing. At any rate, the most likely
scenario is the front sweeps through as an arcing band of showers
with locally higher wind gusts.
Behind the cold front, winds will remain strong as cold air
advection steepens low-level lapse rates and allows for mixing into
the strong wind field along the backside of the departing low
pressure system. Wind gusts of 45 to 55 mph thus appear poised to
continue through sunset, especially near the Illinois and Wisconsin
state line. After sunset, winds will quickly relax and skies will
clear, leading to a relatively cool night with lows in the low to
mid 40s. In spite of the passage of a strong fall storm system,
tomorrow will be surprisingly pleasant with mostly sunny skies and
above-average highs in the upper 50s to lower 60s. Winds will remain
breezy with gusts in the 25 to 30 mph range.

.LONG TERM...
Issued at 320 AM CDT Sat Nov 5 2022
Sunday night through Friday...
The main highlights during the period include:
-Quiet weather with much above average temperatures during the
mid-week period.
-Potentially turning much colder later in the week into next
weekend following a strong cold frontal passage.
The period looks to start Monday on the cool side (at least
relative to what we have been lately) following the passage of a
cold front Sunday night. Winds are expected to turn northeasterly
during the day Monday as a large surface ridge of high pressure
builds into the Great Lakes region. This will result in cooler high
temperatures Monday, with readings expected to be in the low to
mid 50s north, to near 60 far south.
This cool down will be short lived though as upper level height
rises ramp up quickly over the Great Lakes region Monday night
into Tuesday in response to another large northern Pacific trough
digging in over the western CONUS. The associated southerly low-
level wind response to this larger scale pattern shift will in
turn support a return to unseasonably mild conditions, at least
for a day or two. Currently it looks like Wednesday, and
potentially Thursday could be the warmest days, with highs well
into the 60s.
Later in the week model and ensemble forecast guidance support
the northeastward ejection of a significant upper level impulse
across the Rockies and the development of a strong area of low
pressure over the northern Plains. There are signs that as this
storm system moves northeastward into south central Canada and
intensifies that it will drive a strong cold front southeastward
across our area sometime around Thursday of next week. In the wake
of this front, a much colder airmass (winter-like) may then spill
over our area in the wake of this front for the end of the week
and next weekend.

.AVIATION...
For the 06Z TAFs...
Low pressure over western Missouri early this morning will undergo
rapid intensification as it races northward into eastern IA by
daybreak, then into WI into early this afternoon. This storm
system will produce several aviation weather hazards today. These
include:
* Increasingly gusty south winds overnight, with surface gusts of
topping 35 kt at times.
* Strong Low-Level Wind Shear (LLWS) overnight, with 60+ kt of
flow at 1,500 feet AGL.
* Low MVFR CIGs with a period of showers overnight.
* Even stronger winds during the day today, with gusts of 45+ kt
likely.
* Fast moving line of low topped convective showers with a cold
frontal passage late this morning (may produce locally stronger
wind gusts in excess of 50 kt briefly).
While the showers and lower MVFR CIGs will be of some concern
today, by far the most significant aviation weather concern today
revolves around the strong winds expected. Southerly winds are
already occasionally gusting in excess of 35kt, and these winds
will only continue to strengthen over the next several hours
overnight. Very strong winds, (nearing 60 kt) are currently being
sampled around 1,000 ft AGL on the KLOT VAD wind profile, which
suggests that strong low-level wind shear is ongoing, and will
continue to be a significant concern into this morning.
Southerly surface wind gusts are likely to begin to top 40 kt
around, or shortly after daybreak today in advance of a fast
moving cold front. This front is expected to sweep across the
area in the 16 to 17z timeframe, and signs continue to point to
a fast moving narrow band of low-topped showers accompanying its
passage later this morning. While these showers will not
necessarily produce lightning, their convective nature will
allow them to easily drag down some very strong winds from aloft.
As such, we could see a brief period of 50+ kt gusts as this line
of showers along the front races eastward later this morning. I
have added a mention for these locally stronger winds in the
tempo group for showers in the 16 to 17z hour for the main Chicago
area terminals.
After the front races through the area around, or just prior to
midday, winds will shift southwesterly and remain quiet strong,
with gusts around 45 kt, through the remainder of the afternoon.
Expect the winds to ease significantly this evening with sunset.
