308 PM CDT

Through Tonight...

The large footprint of a worked-over environment left in the wake
of this morning's convection continues to leave questions about
the potential for severe weather this evening, with the low-level
and mid-level air mass recovery occurring somewhat independently
of each other. 19Z mesoanalysis, model guidance, and ILX RAOB
indicate quickly steepening lapse rates above 850 hPA, with a deep
layer of 9C/km advecting into the region. This recovery has not
been a concern over the past day. What has been, and continues to
be, the biggest question for severe storm potential this evening
is the ability to sufficiently destabilize the near-surface layer
for initiation. Most of the CWA is finally clearing out after mid-
level clouds and isolated thunderstorms continued a bit longer
into this afternoon than expected across northern Illinois. With
that said, the return of a higher surface theta-e airmass has been
steadily shifting northeastward early this afternoon, with the
theta-e gradient analyzed from just west of the Quad Cities to
just west of Springfield, IL. Extrapolation of this observed
gradient paired with model guidance indicates most of the CWA
should see a nearly full recovery of the low-levels via mainly
advection with some assistance from insolation by early this
evening.

Meanwhile, the kinematic environment is becoming more favorable
for organized convection. Low-level winds continue to increase per
recent DVN/LOT VWP data showing 45kts/40kts as low as 3 kft.
These low-level winds will edge upwards in response to an
approaching mid- level wave evident in WV imagery across southern
MN into far northwest IA. Rising mixing heights will begin to tap
into those stronger winds aloft as the afternoon progresses, with
the forecast of gusts in excess of 40 mph to locally 45 mph for a
window late this afternoon into early evening remaining on track.

Putting this altogether, a highly conditional severe thunderstorm
threat exists after 00Z/7pm through the evening hours roughly
around and north of the Kankakee river Valley westward toward
Peoria. The most significant limiting factor will be the ability
for incoming forcing to erode enough of the substantial low-level
cap currently in place. If sustained deep updrafts can develop,
the environment is favorable for semi-discrete linear segments
with embedded supercell structures capable of producing damaging
wind gusts and large hail. Additionally, a conditional QLCS
tornado/mesovortex threat exists within any convection given
impressively curved low-level hodographs producing effective SRH
values possibly to 500 m2/s2 early to mid- evening. Marginal low-
level CAPE values will be a major detriment to this potential,
with a low-level warm nose below 700 hPa limiting low-level vortex
stretching. Will still need to closely monitor the fine details
of the thermo environment this evening as a kinematic environment
like this that is highly supportive for tornadoes leaves some
concern.

The severe threat will gradually diminish through the night as
convection slowly advances SSE through the CWA, ultimately slowing
across the far southern CWA by daybreak Monday.

.LONG TERM...
330 PM CDT

Monday through Sunday...

The work week continues to present challenges for forecast
confidence as well as conveying the forecast in a simple manner.
The Labor Day holiday remains looking primarily quiet during the
day with rain and some thunderstorm likelihood returning Monday
night into Tuesday morning and possibly much of Tuesday for
northern locations. The spread in forecast rain chances and
temperatures across the forecast area from northwest to southeast
grows through midweek, with higher to lower rain chances and
cooler to warmer temperatures, in general, from west to east.

The cold front will be clearing the far southern forecast area
later Monday morning or so, bringing with it most of the
thunderstorm chances. With the boundary slowing cannot completely
rule out some focus or subtle overrunning in the afternoon in the
far south, but for most areas it looks to remain dry through the
day and early evening. A strengthening high pressure ridge
centered over northern Lower Michigan will squeeze the pressure
gradient some into the afternoon resulting in a northeast wind of
around 15 mph. This should build waves some into the Chicago shore
and climatology would say that we would be at least supportive of
a marginal Beach Hazards Statement for rip currents. Have leaned
that route for the Chicago shore by mid-afternoon with a Beach
Hazards Statement, and then started the Indiana shore under one
first thing in the morning behind the cold front.

As substantial digging of the jet stream occurs over the Rockies
Monday night into Tuesday, the downstream baroclinic zone will
inch back northward over the Midwest and tighten. In addition the
anticyclonic jet will strengthen over the Great Lakes and across
southeast Canada, poising a right entrance region aloft over the
area Monday night through Tuesday. With a period of increased
low-level moisture transport in the low-level jet layer off the
deck, these ingredients should be juxtaposed to support a
blossoming area of rain and some thunderstorms Monday night,
especially after 10 p.m. or so. MUCAPE values are forecast to
climb toward 1,000 J/kg in the southern forecast area and there is
some uncertainty on how the best forcing and instability will
line up. But the dynamics are supportive of at least a marginal
severe threat for hail, and thunderstorm chances all the way to
the northern CWA with periodic heavy rainfall. The heaviest rain
amounts of 2+ inches on high resolution guidance, such as the 3 km
NAM and the HREF, and primarily west of the area but would not be
surprised to see some isolated amounts that high by midday
Tuesday along/north of I-80.

Confidence then lowers significantly and much of that is owing to
the digging trough in the west developing a dislodged, closed
upper low. The 12Z guidance has wobbled back to the west with this
and naturally slowing to eject it. With this being so far west,
more of the forecast area is impinged upon by upper ridging and
drier air from the southeast during midweek. The active
frontogenesis area and 850-700 mb moisture convergence zone
shimmies northwest of the area in the GFS and ECMWF, and the upper
support from the jet region starts to be lost too. It's still too
early to say a heavy rain threat has diminished during that time,
but the potential for a flood threat due to a long duration heavy
rain beyond the day Tuesday looks to have diminished some.

The temperatures continue to show a large spread across the area
thanks to northeast winds, clouds, and some rain in northern areas
and potential for less clouds southeast. Forecast values for
maximum temperatures on Tuesday-Wednesday have 20-25 degree
differences from northwest to southeast for the CWA.

The GFS and ECMWF lift the closed low late this week much further
west of the forecast area than had been the case 24 hours ago.
This shows the common theme in forecasting experience that model
handling of closed lows can be very problematic, and naturally
lowers confidence. With it being further west, the chance of
convection at least lingers further into the week, but it's also
possible we remain dry and actually more mild.

.AVIATION...
For the 18Z TAFs...

An active next 12 hours is expected at all TAF sites as a rather
dynamic system for early September affects the region. A couple
axes of warm-advection induced SHRA with isolated embedded TS will
cross the Chicago metro through 19Z. While a few lightning
strikes cannot be ruled out, coverage and chances are too low to
include in the TAF.

Behind these SHRA, mixing will increase under clearing skies.
Meanwhile, low-level winds above the ground will also be on the
rise, with 850 hPa winds nearing 50 knots by 21Z. Mixing should
become sufficiently deep to tap into at least some of the stronger
winds aloft, producing frequent SSW wind gusts in excess of 35
knots to perhaps briefly 40 knots from mid-afternoon into mid-
evening.

Low-level capping remains a concern for initiation and coverage,
but at least a broken line of strong to severe thunderstorms,
perhaps in the form of semi-discrete linear segments with embedded
supercell structures, will quickly develop around or shortly
after 00z across northern Illinois. Timing into ORD/MDW looks to
be 03-05Z/04-06Z, with the potential for severe wind gusts to 50
knots with the strongest storms. Hail is also possible with any
stronger embedded supercell core.

Other than a potential short period of high-end MVFR ceilings
behind the convection, VFR conditions are expected through the
remainder of the period. The cold front will lag the convection by
a few hours, ultimately veering winds NNW late tonight into
Monday afternoon before a lake-enhanced boundary shifts winds NE
for ORD/MDW/GYY during the mid-afternoon.

.MARINE...
308 PM CDT

A Gale Warning is in effect for all of our nearshore waters
through late this evening. Expecting wind gusts to increase
quickly this afternoon, with occasional gusts to around 40 kts
appearing possible into the evening hours. Wind speeds should
incrementally diminish overnight tonight but will remain elevated
and breezy. Long-duration Small Craft Advisory conditions are then
in the forecast through the end of the upcoming week with a
prolonged period of onshore gusty north to northeasterly winds
resulting in building and choppy wave action.
