Tornado Warning 11, NWS Chicago, IL

Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
712 PM CDT Mon Jun 13 2022

.MESOSCALE DISCUSSION...
Issued at 548 PM CDT Mon Jun 13 2022

With storms developing and quickly intensifying within a volatile
environment we have coordinated a tornado watch with the SPC for
northeastern IL and northwestern IN. Low level helicity/shear
along the surface frontal boundary will support super cells with
very large hail and a tornado threat. This threat will continue
into the early evening, likely waning through the mid to late
evening.

.SHORT TERM...
Issued at 357 PM CDT Mon Jun 13 2022

Through Wednesday night...

After today's shower and thunderstorm activity departs, attention
will return to a brief spell of record or near-record heat that will
grapple the region through Wednesday. For more information regarding
today's thunderstorm threat, please refer to the mesoscale
discussion above.

A warm front currently draped across the forecast area will
eventually lift northward into Wisconsin and Michigan by Tuesday
afternoon, paving the way for widespread 95-100 degree temperatures
to build across the entirety of our CWA by the mid-afternoon hours.
Dew points, which are already in the 70s and even 80s across the
area, will remain at oppressive levels overnight and into Tuesday,
yielding heat indices that will peak in the 105-110F range across
most of the CWA. Not much relief will come overnight with low
temperatures expected to generally remain in the mid to upper 70s
across the area, though some temperature readings possibly might not
even dip below 80 degrees within the core of the Chicago metro
urban heat island. High temperatures on Wednesday should be
similar to or perhaps a smidge lower than Tuesday's highs, while
dew points will remain elevated but likely a few degrees lower
than what they are expected to be on Tuesday. Peak heat indices on
Wednesday will thus be a little lower compared to Tuesday, but
will still hover at or around 105F, so maintained the going Heat
Advisory from Tuesday into Wednesday.

Despite the plethora of low-level moisture, capping aloft will
suppress any attempts at deep convection on Tuesday and Wednesday
and keep us dry through at least Wednesday evening prior to the
arrival of a cold front late Wednesday night. Strong to severe
thunderstorms may be ongoing near the front as it approaches our
forecast area, but will likely be on a downward trend in both
intensity and coverage as they encounter an increasingly stable
environment with time and eastward extent. Nevertheless, at this
point in time, can't rule out these storms still being severe as
they approach the I-39 corridor with damaging winds as the primary
threat due to a favored quasi-linear storm mode owing to deep
layer shear vectors being mostly parallel to the initiating cold
front.

.LONG TERM...
Issued at 357 PM CDT Mon Jun 13 2022

Thursday through Monday...

Behind the cold frontal passage late Wednesday night/early Thursday
morning, things should remain fairly quiet across our area as
another upper ridge builds across the central CONUS. Conditions are
favored to remain dry after the front has departed through at least
early next week as high pressure dominates over the region. While
some relief from the high temperatures and humidity is expected as
we head into the weekend, there are signs that temperatures will
climb back into the 90s for the start of the next work week.

.CLIMATE...
Updated at 357 PM CDT Mon Jun 13 2022

Record or near record warmth is forecast. Here are the current
records for Chicago and Rockford:

Chicago
                      High          High Min
Tuesday (6/14)      99 (1987)       75 (1981)

.AVIATION...
For the 00Z TAFs...

* Severe thunderstorm moving east-southeast near MDW/GYY prior to
  01z.

* East to northeast winds expected in the wake of the storm for a
  few hours before turning south or southeast later this evening.

* Possibility of some fog overnight until around daybreak.

* Breezy southwest winds Tuesday.

Severe thunderstorm tracking southeast across the Chicago metro
will likely pass near GYY toward 0030z. Otherwise, wind direction
trends will be a challenge into the mid evening in the wake of
the storm, though KRFD should be more steady state. Expect that a
east to southeast direction will prevail behind the storm, though
there will likely be variability. Several frontal boundaries
remain in the area and should track back to the north and east
allowing winds to settle into the south to southeast direction.
With the very moist atmosphere, there may be some patchy fog that
develops overnight which would dissipate after daybreak. Could
also see some scattered IFR clouds develop with that. South to
south-southwest winds will set up for Tuesday with VFR
conditions.
