.DISCUSSION...
Issued at 213 PM EDT Fri Sep 26 2025
Behind the cold front that moved through early this morning,
satellite imagery shows mostly sunny skies across Upper Michigan
this afternoon as high pressure ridging briefly moves into the area
this evening. As the winds continue to die-down over Lake Superior
this afternoon, expect Low Swim Risk conditions to return to the
beaches of Marquette and Alger counties by around 4 PM as waves drop
from just below 4 ft at noon to around 2 ft or less. Given the
cooler air behind the front, expect highs this afternoon to be
somewhat muted, only getting into the 60s. However, with skies being
sunny and dry air moving in, we could see min RHs drop to into the
upper 30 percents in some of the interior areas before recovering
during the overnight hours. Because of the dry air behind the
front/with the high pressure ridging, no fog is expected
tonight/Saturday morning. The lack of cloud cover should allow
temperatures to bottom-out into the lower 40s over at least the
interior central and east late tonight/early Saturday morning.
While we do have another cold front skirting the area Saturday, no
rainfall is expected with it as the better forcing will be located
well north of the area. While an isolated shower or thunderstorm
cannot be completely ruled out, rain chances are expected to be
around 10% or less. With dry air moving in behind the cold front
Saturday, we could once again see min RHs drop into the 30 percents
in some of the interior areas Saturday afternoon, mainly in the
western U.P.. In addition, thanks to the warm air advection ahead of
the front, expect temperatures to be warmer Saturday, reaching into
the upper 60s in the west to mid 70s in the central and east.
Expect high pressure ridging sitting overtop us to keep the U.P. dry
for the rest of the period, with above normal temperatures expected
to continue through next week as warmer air from the south sneaks
into the region.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 145 PM EDT Fri Sep 26 2025
VFR conditions will continue through the forecast period at all
the TAF sites. East to northeasterly winds less than 10 kts are
expected to prevail through the evening across the area. Winds
will become southerly after midnight tonight and westerly on
Saturday. Wind gusts around 20 kts expected Saturday morning at
all terminals.

.MARINE...
Issued at 213 PM EDT Fri Sep 26 2025
Light winds of 20 knots or less continue the rest of today as high
pressure moves through the region. However, as a cold front
approaches the lake tonight, expect winds to pick up from the south
at 20 to 30 knots, particularly over the central lake; a gust or two
up to 30 knots, while not expected, cannot be completely ruled out
either at this time. Along the front, there may be an isolated
shower or thunderstorm over Lake Superior Saturday morning (15% or
less), but for the most part no precipitation is expected. As the
cold front moves through Saturday morning, expect to see winds veer
to the west with a few gusts up to 20 to 25 knots before picking up
over the western half of the lake from the west-southwest late in
the day; expect the winds to die back down to 20 knots or less again
Saturday night as high pressure returns to the region. Light winds
of generally 20 knots or less look to continue through most of the
rest of next week as high pressure ridging settles overtop the Upper
Great Lakes.
