.DISCUSSION...
Issued at 1126 AM CDT Tue Sep 9 2025
A stationary front currently positioned from the Brainerd Lakes
stretching northeast along the North Shore is leading to some
low stratus and isolated showers. This will continue as the
front slowly moves to the southeast for this afternoon through
Wednesday. A rumble of thunder or two are also possible with the
smallest amount of CAPE available to these showers. As the
front moves away from the Northland, a high pressure is filling
in behind with clearing skies. Tonight, lingering moist
conditions from today`s rain may lead to more patchy dense fog,
similar to what we saw this morning. The highest chances will be
in areas that see skies clearing today and areas along Lake
Superior. A dense fog advisory may be needed across much of the
area and the nearshore waters tonight.
High pressure combined with an upper level ridge will settle in for
the mid week, leading to quiet weather until Friday. Partly
cloudy to mostly sunny skies are expected, and warming
temperatures into the 70s each day.
Thursday night, the backside of the ridge will move over the
Northland and the high will move off to the east. Warm air advection
will lead to increasing chances for showers and storms for Friday.
This flow will remain for the out of the south for the majority of
the weekend, with several slight chances for rain showers and
general thunderstorms. Though the greatest uncertainty is not
necessarily whether showers will occur, but where. No severe weather
is expected during the weekend.
Into next week, a small shortwave will move up the southwesterly
flow, leading to more widespread chances for showers and storms.
More details will be available as we move through the week.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1126 AM CDT Tue Sep 9 2025
Low MVFR/IFR ceilings continue into this afternoon with a slow
front moving southeast throughout the day. INL has already
lifted to VFR and is expected to remain throughout the rest of
the day. Next concern will be the return of low ceilings and
visibilities tonight with fog, especially near Lake Superior and
where skies clear. Sites most likely to see dense fog tonight
are INL, HIB, and DLH. BRD will also have a decent chance for
fog if skies remain clear into this evening.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 1126 AM CDT Tue Sep 9 2025
Foggy conditions over Lake Superior continue. Fog is expected
to slowly clear throughout the afternoon, but will likely
return quickly this evening into the overnight hours. An
additional dense fog advisory may be needed for much of the
western Lake Superior near shore waters. Additionally, some
scattered showers and an occasional storm are possible along the
South Shore this afternoon.
