.DISCUSSION...
Issued at 244 AM CDT Sat Sep 27 2025
Early this morning, a localized fog and low-hanging stratus
bank is meandering about our northern-most counties and up into
far southern WI. Immediately south of this bank is a frontal
boundary that`s become stalled near the I-90 corridor. Areas of
fog look to remain over areas near and north of I-90 into the
early morning with some localized instances of dense fog
possible. Elsewhere, we`re seeing clear skies with temperatures
ranging from the 50 across outlying areas to the 60s in the city
and around the interior metro area.
Today will be another unseasonably warm day. Temperatures
yesterday overperformed by a couple of degrees from what
guidance was showing with much of our CWA having made it into
the middle 80s, and it looks as though that may be the case
again today. Most camps resolve highs in the lower to middle
80s, not much change from 24 hours ago. However, low levels
temps are anticipated to be a couple of degrees warmer than
yesterday and guidance resolves very modest surface warm
advection today ahead of an approaching cold front. And with
another dry and sunny day in store, opted to bump high
temperatures in the forecast just a couple of degrees from
guidance to get middle and upper 80s area-wide.
A cold front that`s currently working east across MN will pivot
across WI today and become more zonally-oriented before pushing
south across the CWA late this evening. This cold front won`t
amount to any precip, but a few pieces of high-res guidance,
specifically the HRRR, ARW, and FV3, are pretty excited about a
push of breezy NNE winds behind this front late tonight across
our northern CWA and especially over Lake Michigan toward the
Lake (IL) and northern Cook County shores. Did boost winds a
little bit in the forecast for this potential, but may have to
even moreso on the dayshift as confidence builds.
There is uncertainty in the degree of cooling that we`ll see
behind this front and what it means for tomorrow`s temperatures,
particularly near and north of I-80. Modeled high temps north
of I- 90 range from the lower 70s to around 80 degrees.
Regardless, onshore flow during the day should bring the coolest
conditions tomorrow to areas near and downwind of the lake.
Downtown Chicago is favored to max out in the lower 70s while
inland areas are forecast to reach the lower and middle 80s.
The regional pattern continues to look awfully quiet next week.
Conditions will remain unseasonably mild with more 80s forecast
into next week. Another cold front will drop move through the
area sometime during the middle of next week and medium-range
guidance favors slightly cooler conditions for the back half of
the week.

.AVIATION /12Z TAFS THROUGH 18Z SUNDAY/...
Issued at 613 AM CDT Sat Sep 27 2025
Light south to southwest winds at the start of the TAF period
should become decidedly southwest and increase to 10 to 12 kt
by midday. Wind magnitudes will ease after sunset this evening.
A weak cold front with an associated northwesterly wind shift
should then move through the terminals after sunset. Winds will
trend northeasterly by the end of the TAF period.
