.KEY MESSAGES...

- Well below normal temperatures for today and tomorrow with
  sub zero lows and afternoon highs in the single digits to
  teens.
- Warming again for the coming work week with a daily
  freeze/thaw cycle likely. Some days with high temperatures in
  the mid to upper 40s are expected mid to late week with
  pockets of 50s possible.
- A light dusting of snow possible for the Borderlands Tuesday,
  and then a more active pattern could start up again towards
  the end of the week. Depending on exact storm track and
  temperatures, accumulating mixed precipitation could impact
  the Northland.

.DISCUSSION...
Issued at 116 PM CST Sat Feb 28 2026

As high pressure continues to slide into the Upper Midwest and
across the Great Lakes this weekend, the Northland should stay
under fairly calm and cold conditions. Daytime highs are
expected to just barely top out in the single digits and teens
today and tomorrow, with sub zero overnight lows. While some mid
to high clouds remain prevalent today and this evening from a
band of snow to our south, clearing is expected under the heart
of the high pressure tomorrow to make for a congruous sunny
Sunday.

Into next week, well find ourselves stuck in the synoptic
doldrums as persistent upper level ridging over the gulf and
troughing over the southwest advects copious amounts of moisture
and warmth into the south-central CONUS but troughing over
Hudson Bay locks our area into fairly zonal flow and on the
right exit region of the prevailing jet stream to our north. A
momentary break in that jet stream could yield itself to a
little clipper brushing over the international border Tuesday
that might bring a light dusting of snow to the far north CWA.
This pattern should bring warmer temperatures into the region,
with highs above freezing expected for all of the Northland
through the week but a refreeze at night is likely.

Later in the week, global models are generally in agreement
that troughing should begin to move over the central CONUS and
allow for additional moisture and warm air advection into our
area. This will probably mean warmer high temperatures at least
into the 40s mid to late week with some areas along the southern
CWA border possibly struggling to get below freezing at night.
With current snowpack conditions, some transformation and melt
is likely through the week, and this may start to eat away at
the already meager snowpack that exists along the southern edge
of the CWA. The freeze/thaw cycle will also likely lend itself
to the potential for fog development.

Ensembles are starting to get a little more attached to the idea
of a Colorado Low type system that could move over MN/WI in the
late Thu - early Sat timeframe impacting the Northland.
Depending on the track and intensity of this system, some areas
of heavy mixed precipitation (rain, freezing rain, snow) could
be possible. At this time range however, it could also shift and
miss our area entirely. Something to keep an eye on for now.
Once that system moves through, synoptic pattern agreement
breaks down with solutions ranging between having more Colorado
Low/Gulf air influence from the south or a return to some
slightly cooler air and systems that track along the
International Border. Eventually ensembles do come back to some
agreement showing that cooler airmass pushing into northern MN
by mid March, but the disagreement on how fast we get there and
what kind of systems we experience before that point is large.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 515 PM CST Sat Feb 28 2026

Broken ceilings at around 8 kft and higher will persist this
evening, but generally clouds are expected to start clearing out
with high pressure passing through on Sunday. Winds are expected
to be light and variable as high pressure passes through with
VFR conditions through the period.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 116 PM CST Sat Feb 28 2026

Fairly calm conditions under high pressure this weekend with
light winds out of the northwest to west through midday Sunday.
Through Sunday afternoon and evening, winds turn to become
southwesterly into Monday. Those SW winds could increase into
Monday as warm air surges into the area. Some gusts in excess of
25 knots are possible Monday along portions of the North Shore
from Taconite Harbor to Grand Portage. Calmer conditions return
into Tuesday.
