.DISCUSSION...
Issued at 210 PM CST Wed Nov 26 2025

This system is beginning to exit and snow is ending across much
of the Northland. Lake effect snow is lingering along the South
Shore, still with plenty of moisture and high lapse rates (7-10
C/km) as cold air is advected over Lake Superior. This lake
effect is expected to affect far northern portions of Ashland
and Iron counties through early Friday, dumping an additional
6-10 inches over portions of Iron County. The heavy snow will
continue into tonight, and the Blizzard Warning will still be in
effect due to the snow rates, winds, and low visibilities still
being seen in these areas. A Winter Weather Advisory will be
considered is snow begins to end early, but not expecting any
additional headlines after early Thursday morning.

The snow will be here to stay as temperatures remain below
freezing for the rest of the forecast period, with high
temperatures in the 20s and lows in the teens across the
Northland. By early next week, highs will reach only the teens
and lows will be around to below zero.

This weekend, an upper level trough will dive south over the
Rockies and another Colorado low will move across the Midwest.
This system, however, looks to move much further south than this
previous system, and the heaviest snow looks to stay to our
south. However, there is enough upper level forcing and moisture
that some light to moderate snow is possible across northwest
Wisconsin. A few inches are possible, and won`t be nearly as
impactful as this previous system. Winds, while elevated, will
not be nearly as strong, with gusts only expected to reach 25-30
mph with this system.

Again, after this next system moves off to the east, lake effect
snow will once again start up along the South Shore. However,
the window for efficient lake effect will be short as winds turn
from the east to the northwest as sufficient moisture exits the
region, and only a few additional inches are expected for
northern Ashland and Iron counties compared to surrounding
areas.

Global models show our active pattern continuing after this
weekend, but there is nothing conclusive so far due to
discrepancies between them.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 525 PM CST Wed Nov 26 2025

MVFR ceilings engulf the Northland this evening and are expected to
largely persist through the forecast period. Radar still shows some
lake effect snow showers hitting the South Shore. Coverage of the
snow showers are expected to diminish and remain over Ashland and
Iron counties into tomorrow. As colder air pours in from the
northwest we may see some streamers off of the larger inland lakes.
Lake of the Woods in particular may rouse up some snow showers for
HIB/INL tomorrow morning.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 210 PM CST Wed Nov 26 2025

Strong northwest winds continue on the back side of the system
that brought widespread snowfall last night. Gales are expected
to last into tonight, and Gale Warnings are in effect. Waves
along the South Shore from west to east will increase to 7 to 14
ft. Winds and waves will begin to decrease tomorrow, but
conditions hazardous to small craft will linger into Friday
morning. Winds will increase again over the weekend as another
system moves to our south. Chances for gales are low, but
conditions hazardous to small craft will return.
