.DISCUSSION...
Issued at 226 PM CDT Tue Sep 23 2025
Surface high pressure extended from Hudson Bay into the Upper
Midwest, Northern Plains and Northern Rockies early this
afternoon. Most of the lingering low stratus had lifted along
the fog from earlier this morning leaving mainly fair weather
cumulus across the region. Skies will likely clear this evening
with the loss of daytime heating. However, low level moisture
remains in place and will again lead to the development of low
stratus and fog overnight. While it is not expected to be as
widespread as the past few nights, it will be dense in spots,
especially from the Twin Ports to the Iron Range and Brainerd
Lakes regions. Depending on how dense and widespread it is,
Dense Fog Advisories may be needed.
High pressure will then control the remainder of the forecast
period bringing dry conditions along with generally above normal
temperatures. There will be a few weak cold frontal passages
during this period with the strongest being Friday night into
Saturday. While this looks to be a mainly dry passage, aside
from some low pops along the International Border, there will be
some cooler air that arrives behind this front for Saturday that
will bring closer to normal highs in the 60s and lower 70s.
Temperatures then warm back into the 70s for the remainder of
the weekend and into early next week.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 620 PM CDT Tue Sep 23 2025
Fog will form tonight and create areas of dense fog resulting in
visibilities less than one quarter mile into Wednesday morning.
Winds will be light less than 10 knots.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 226 PM CDT Tue Sep 23 2025
High pressure will bring light winds at 10 knots or less to
western Lake Superior tonight through Wednesday night. Winds
will then turn southwesterly on Thursday with gusts to 15 knots
from Gran Marais to Grand Portage. Main concern for the next
few days will be another round of fog that will likely develop
tonight and linger into Wednesday. This round is not expected to
be as widespread and will likely dissipate quicker than this
morning`s round.
