.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 /06Z TAFS THROUGH 12Z MONDAY/...
Issued at 1147 PM CDT Sat Sep 27 2025
Winds will remain light and turn from northwest to northeast
through the overnight period, and remain northeasterly through
the remainder of the TAF period. Wind magnitudes tomorrow may
remain fairly light (5kt or less) through mid-afternoon before a
lake breeze reinforces speeds to 10kt or so. Occasional periods
of mid-level clouds may occur, but clear skies should generally
prevail.
