.DISCUSSION...
Issued at 214 PM CDT Mon Sep 22 2025
Very weak troughing in northwest Ontario drops southward this
afternoon into the Borderlands. This is helping promote some
weak instability showers. Radar shows the expected nature of the
weakly supported showers collapsing soon after formation, which
is likely to persist into the evening hours today in the
Arrowhead. Any rainfall would be less than 1/10 of an inch in
the Arrowhead to Iron Range area over the next few hours under
these widely scattered rain showers.
Another round of dense fog moves onshore again tonight from 7-10
PM this evening. The first round of Dense Fog Advisories for
those areas along or near Lake Superior go into effect at 8 PM
with all other inland zones, except Price County, at Midnight
tonight. Expect another night and Tuesday morning commute with
visibility less than 1/4 mile. All Advisories remain in effect
until 11 AM Tuesday, but some inland zones are likely able to be
dropped early tomorrow morning as visibility improves 9-10 AM.
More limited dense fog coverage is expected to return again
Tuesday night.
The remainder of the forecast features a very quiet early fall
pattern with temperatures in the upper-60s to low-70s and less
than 10 percent chances of additional rainfall beyond this
evening.

Issued at 632 PM CDT Mon Sep 22 2025
Fog is expected tonight, and it should be dense at times. Expect
fog to develop at DLH right around sunset, and the onset of fog
should be fairly quick with light onshore and upslope flow. In
the next hour, a brief period of partially clearing skies can`t
be ruled out. Elsewhere, the fog should be more gradual to
develop. IFR to LIFR conditions are expected everywhere at times
later tonight through Tuesday morning, then gradual clearing
through the morning with VFR conditions expected everywhere
Tuesday afternoon. Light and variable winds with high pressure
in the vicinity.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 214 PM CDT Mon Sep 22 2025
Dense marine fog continues through at least late morning
tomorrow, with Dense Marine Fog Advisories in effect for all
nearshore waters of western Lake Superior. Clearing and
improving visibility may occur Tuesday afternoon ahead of
another possible round of dense fog Tuesday night into
Wednesday. Winds remain light and variable under 10 knots.
