.DISCUSSION...
Issued at 228 AM CDT Sat Sep 27 2025
A weak front will move through the region this morning,
bringing an increase in clouds. This cloud cover will act like a
blanket, keeping our overnight temperatures from dropping as
much as they did last night. While this system will be dry for
most, a few isolated showers are possible along the Canadian
border, though the air is so dry that much of it may not even
reach the ground. As the front passes, expect breezy northwest
winds to develop for Saturday with gusts up to 25 mph, which
could be a bit stronger right along the North Shore of Lake
Superior. The big story then becomes a very stable and pleasant
weather pattern setting up for the entire upcoming week, as a
large area of high pressure builds in. This will lead to an
extended period of dry weather with plenty of sunshine and
temperatures warming to above-normal levels, a pattern that
looks to hold steady as we head into the beginning of October.
There are some hints of a pattern change into next weekend, but
this kind of ridging typical holds fast and models are probably
overdoing its exit.

.AVIATION /12Z TAFS THROUGH 12Z SUNDAY/...
Issued at 547 AM CDT Sat Sep 27 2025
Mostly VFR except some low stratus fog in NW WI in place ahead
of a fast moving cold front this morning. This cold front will
exit to the east today. Behind the front, winds quickly shift
northwesterly and remain gusty through the day before backing
off this evening and backing to the southwest.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 228 AM CDT Sat Sep 27 2025
Mariners on Lake Superior should expect deteriorating
conditions through the morning as a cold front sweeps across the
lake. Northwesterly winds will become breezy, likely gusting to
20-25 kts, which will build waves to 2 feet across the Apostles
and create choppy seas. Winds could be locally stronger right
along the coast as the cooler air passes over the relatively
warmer waters. The Apostle Islands may have brief Small Craft
Advisory conditions this afternoon. These winds and waves should
begin to gradually subside later this afternoon and evening as
the front exits the region. The big story for boaters is the
extended period of calm and favorable weather that follows,
beginning Sunday and lasting through the entire upcoming week. A
large area of high pressure will settle over the Great Lakes,
leading to generally light winds, calm seas, and mostly sunny
skies.
