.DISCUSSION...
Issued at 320 AM CDT Fri Sep 26 2025
Today should be a fairly nondescript day with sunny skies, a light
ESE breeze, and temperatures rising back into the 60s and 70s this
afternoon. With clear skies overnight, some cold temperatures have
overachieved in portions of Koochiching and northern St. Louis
County, dropping into the mid to upper 30s. The coldest temperatures
are fairly isolated and as we`re well past the time that folks would
be able to cover any plants, we`ve opted to not issue a very last
minute Frost Advisory. Northeast winds pick up at the head of Lake
Superior this afternoon pushing waves up along Minnesota and
Wisconsin Point beaches, which will lead to a high rip current risk.
A Beach Hazards Statement is in effect.
A weak, mostly dry cold front should bring some partly cloudy skies
and a switch in wind direction this evening and overnight into
Saturday morning. This front has about a 10-25% chance of bringing
some sprinkles or isolated light rain to the Borderlands overnight.
Some breezy NW winds are possible along and behind this front, with
gusts of 20-25mph possible. This will need to be monitored in the
12z suite of models for the North Shore. The zestiest solutions from
some of the CAMs are suggesting gusts in excess of 25 mph, which is
above the current forecast. While there isn`t the best CAA to aid a
katabatic wind gust scenario along the North Shore, the pressure
differential and frontogenesis could help enhance some downslope
winds.
Dominant high pressure from an omega block should continue through
early next week. Little to no precipitation is expected through mid
next week and temperatures remain above normal. Global models
suggest that troughing could start to push into the Northern Plains
mid to late next week, bringing chances of rain back to the
Northland. While there are some scattered precipitation chances in
the forecast late Wednesday and Thursday, there is better global
model agreement for some rain on Friday. This of course is a ways
away and things will change.

.AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
Issued at 1150 PM CDT Thu Sep 25 2025
VFR conditions are expected through the TAF period. Light north
winds overnight become northeast into Friday morning. Winds become
east to southeast through this afternoon with some gusts of 15-20
knots possible.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 320 AM CDT Fri Sep 26 2025
Winds turn to come out of the northeast today, with some gusts of 15-
20 knots possible for the head of the lake and areas around the
Apostle Islands. At this point a small craft advisory is not
expected, but conditions will be monitored for possible issuance. A
mostly dry cold front sweeps across the area from west to east into
Saturday morning. This could lead to a brief period of gusty
northwest winds around midnight to sunrise before winds become
southwesterly into the daytime. Generally expecting those southwest
winds to stay below 15 knots at this time. Southwest winds continue
into Sunday.
