.DISCUSSION...
Issued at 233 AM CDT Sun Sep 28 2025
Not much to speak to here as the forecast continues to favor
quiet conditions through the period. Early this morning, a
zonally- oriented cold front is steadily dropping southward
across the CWA. A few northerly gusts to 15-20 mph have been
reported immediately behind the front, but otherwise skies
remain clear and we`re not even seeing any noteworthy cooling in
its wake. Temperatures are sitting in the upper 50s and 60s at
the time of this writing.
Today will be a similar story to yesterday, but noticeably
cooler for some. Surface high pressure will be centered over the
lower Great Lakes today bringing more sunny skies to the
region. Most inland areas are forecast to again reach the middle
to upper 80s this afternoon. However, onshore flow throughout
the day will keep communities near and just inland from the lake
a few to several degrees cooler. Lakeside locales will likely
fail to make it beyond the lower or middle 70s.
High pressure will dominate the region through the week.
Conditions will remain unseasonably warm, especially through
Tuesday. Only slightly cooler temperatures are favored for the
latter half of the week, but much of the CWA may very well be
seeing 80s every day this week. Cooler daytime conditions will
continue to be found near the lakeshore for the next several
days with persistent onshore flow. Ensemble PoPs are basically
zero through the end of the workweek, but dry conditions are
highly favored until at least early next week.

.AVIATION /18Z TAFS THROUGH 00Z TUESDAY/...
Issued at 1215 PM CDT Sun Sep 28 2025
There are no significant aviation forecast concerns anticipated
through the period.
Broad surface high pressure will dominate across the Great Lakes
region through the forecast period and beyond. Overall, this
will result in quiet weather conditions, with little in the way
of cloud cover and light surface winds. Accordingly, after a
period light and somewhat variable wind directions tonight,
expect another afternoon lake breeze to move inland and result
in an easterly wind shift at the Chicago area terminals again
Monday afternoon.
