afternoon into the early evening. There is a level 2/5 severe
weather risk for most of the area with damaging winds as the
primary severe weather hazard.
- Hot and humid conditions are expected today with peak heat
indices of around 100 degrees.
- MUCH cooler and less humid Thursday with gusty northerly winds
and dangerous swimming conditions at Lake Michigan beaches.

.DISCUSSION...
Issued at 343 AM CDT Wed Jul 16 2025
Through Tonight:
Today`s main focus is on the likelihood of thunderstorms this
afternoon into this evening as a convectively-augmented
shortwave trough/MCV tracks through the region. At press time,
this feature was located in western Iowa and was powering an
expansive thunderstorm complex extending from central Iowa
southwestward through northeastern Kansas. The expectation is
for this thunderstorm complex to continue gradually losing steam
with time through the remainder of the night while exhausting
an outflow boundary, though (perhaps unsurprisingly in this
moist, unstable mid-summer air mass) it appears that this
complex will persist longer than what CAM guidance is showing,
which does throw some additional uncertainty into the forecast
for today.
Assuming that this complex does eventually largely die off
prior to reaching northern Illinois, additional thunderstorms
are likely to redevelop near the Mississippi River during the
late morning/early afternoon either along the complex`s remnant
outflow boundary or a cold front lagging slightly behind this
outflow boundary. The greatest coverage of thunderstorms is
expected to be found close to the center of the MCV, which CAM
guidance unanimously depicts tracking through southern/central
Wisconsin. Between the MCV/shortwave and convergence along
surface boundaries, there should still be enough forcing to
support at scattered thunderstorms in our forecast area, and
most of the 00Z CAM suite actually depicts a broken or solid
line of thunderstorms marching across our CWA later today. The
orientation of the surface boundaries and the influence of any
morning convection/cloud debris will likely play key roles in
just how widespread convection ultimately ends up being this
afternoon.
While mid-level lapse rates will be lackluster, progged
thermodynamic profiles support a threat for damaging winds from
water-loaded downbursts with the strongest thunderstorms that
develop today. That would especially be the case within any
bowing segments that materialize. While damaging winds by and
large appear to be the primary severe weather hazard today,
deep-layer shear profiles closer to the core of the MCV may be
favorable enough to support at least transient supercellular
structures, which could carry a slightly greater threat to
produce isolated large hail or weak tornadoes in an environment
that is otherwise not overly favorable for either of those
hazards. A lower-end threat for brief, weak QLCS tornadoes also
could not be completely discounted with any northeastward-
surging bowing segments that develop north of I-88 given the
expected presence of 25-30 kts of 0-3 km shear there.
It appears that convection on the MCV`s southern flank should
be progressive enough to preclude an appreciable flash flooding
threat from materializing this afternoon and evening, though it
should still be said that precipitable water values pushing 2"
and 12000-15000 ft warm cloud layer depths will support very
efficient rainfall rates, so couldn`t completely rule out some
hydrologic concerns materializing in some of our usual trouble
spots even if there isn`t much in terms of training convection.
One area to watch for a potentially higher threat for flash
flooding would be our far southern CWA tonight as the outflow-
augmented front may stall out there as it takes on a more zonal
orientation. A strengthening low-level jet overriding this
boundary could foster the development of training convection
just north of this boundary, though this is not a sure thing
yet, and if this does occur, it`s possible that this ends up
occurring south of our CWA.
Lastly, it will be hot and humid prior to the arrival of the
thunderstorms later today. Assuming that storms don`t arrive
earlier than expected, high temperatures are forecasted to
reach the upper 80s to low-mid 90s this afternoon, which, when
combined with low-mid 70s dew points, would result in peak heat
indices near 100F.

Thursday through Tuesday:
Fairly strong high pressure (~1020mb) for mid-summer combined
with push from earlier convection should send the composite
outflow boundary/cold front south of our area Thursday. In the
wake of the front, look for much cooler and less humid air to
filter into the region. Morning stratus should break up into a
SCT V BKN stratocumulus deck during the afternoon, with this
cloud likely aiding in keeping temps cooler. Thursday afternoon
temps could be around 20F in the Chicago area with readings in
the low to mid 70s with a brisk wind off the lake. That brisk
wind off the lake will also help build up larger waves and lead
to hazardous swim conditions at unprotected Lake Michigan
beaches Thursday into Thursday night.
Friday will be warmer, but with still comfortable humidity
levels. Boundary that will have pushed south of our area
Thursday should stall near the Ohio River before heading back
north as a warm front Friday night into Saturday. There`s been a
pretty consistent signal in bringing a convectively enhanced
shortwave across the region later Friday night into Saturday.
Still several days out, so exact timing of this feature and
where exactly it tracks may need to be refined in coming days,
but the general idea of an MCS moving across the mid-Mississippi
Valley in this time frame, possibly affecting portions or all
of our area, continues.
Medium range guidance has trended toward slightly more
amplified northern stream troughing over the Great Lakes into
New England later in the weekend. This would allow for a
transient sfc high to move across the Great Lakes Sat night into
Sunday. This, combined with the prior MCS, could push the
effective boundary and rain/storm chances south of our area.
Confidence is too low to reduce or remove NBM POPs for Sunday,
but there is an increasingly plausible scenario where the
second half of the weekend could end up dry and a bit cooler
and less humid.
Looking ahead to the first half of next week, there continues to
be a consistent signal in medium range guidance that a strong
upper level ridge and associated dome of heat will build over
the central and eastern portions of the nation. In this time
frame, we`d expect that the front that pushes southward some
Sunday will lift back north bringing the potential zone of MCS
activity with it back into our area for a time early next week.
By the middle of the week, the upper ridge is progged to become
anomalously strong and centered over the lower and middle
Mississippi Valley. Assuming MCS activity doesn`t significantly
impede the northward movement of the boundary, our area could
get into a bout of some potentially dangerous heat during the
middle and end of next week. Operational runs of the GFS and
ECMWF both are explicitly forecasting 80F+ dewpoints
accompanying the heat, which given we`ll be in the heart of
evapotranspiration season, may not be unreasonable. Still plenty
of uncertainty regarding if convection can temporarily impede
the northward building heat, but concern is growing that
potentially dangerous heat wave could develop next week in or
near our area.

.AVIATION /06Z TAFS THROUGH 12Z THURSDAY/...
Issued at 1214 AM CDT Wed Jul 16 2025
- SCTD +TSRA expected to impact terminal airspace late this
afternoon into early this evening.
- MVFR CIGS possible in the wake of the storms tonight.
ISOLD SHRA will continue to percolate over northern IL through
sunrise. Coverage is expected to remain low enough to not
warrant more than VCSH in TAFs.
Primary forecast concern will be timing and coverage of +TSRA
later this afternoon and evening. May need to fine tune timing
a bit later today based on observational trends, for now there`s
no reason to make any adjustments to timing from previous TAFs
with guidance still supporting that timing. A period of gusty
westerly winds is possible in the wake of the storms this
evening, but magnitude and duration of any higher winds is low
confidence given large spread in model guidance.
Finally, there is a pretty strong signal in guidance showing
MVFR CIGS tonight. Already seeing a large bank of MVFR stratus
over the Plains on the back side of this system, so while it
isn`t climatologically all that common this time of year with
westerly winds, have added in some MVFR CIGS for tonight.
