.DISCUSSION...
Issued at 425 AM CST Sun Feb 1 2026
A fast moving Alberta clipper is tracking into the region
today, bringing widespread light snowfall to northeast Minnesota
and northwest Wisconsin. While deep dry air near the surface
has initially delayed the onset for some eastern areas, snow
will eventually have a quick onset as moisture fills in with
the progressing system. Most of the Northland can expect 1 to 2
inches of accumulation through this evening. However, southerly
flow ahead of the cold front will provide some orographic
enhancement along the North Shore, where 3 to 4 inches could
accumulate in the higher elevations. Winds up to 30 mph has and
will continue to blow snow around throughout the day, which may
lead to some localized visibility reductions on roadways.
This afternoon into the evening, cold air advection leading to
favorable lapse rates and plentiful low level moisture within
the dendritic growth zone may keep scattered snow showers
lingering behind the main front into the evening hours. Strong
southerly winds this morning will shift to the northwest by
tonight, ushering in a brief cooling trend with lows dropping
near or below zero for many inland locations.
Looking ahead to the work week, the region will remain under a
relatively cold air mass, but temperatures will moderate
compared to recent extreme cold. Highs in the teens and 20s are
expected Monday through Wednesday. By Thursday, a more potent
clipper system will bring robust warm air advection ahead of
it and will push high temperatures into the mid-30s, likely
causing a transition from snow to rain or a rain and snow mix
for much of the area. Latest thermal profiles show a vertically
stacked freezing line, suggesting a clean rain to snow
transition, though that is subject to change with future
forecasts as there is still high uncertainty five days out. The
storm track is also uncertain, which will affect where
precipitation types will fall.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 538 AM CST Sun Feb 1 2026
Snow continues to move east throughout this morning. A dry slot
has set up where conditions lift to VFR for a couple hours
before a second round of snow once again lowers conditions to
MVFR/IFR. Winds will switch from the south to the northwest with
the cold front associated with this system and winds will
increase to around 20 kts throughout the day. Some scattered
snow showers may linger into the evening from continued cold air
advection and low level moisture, but confidence is not high
enough to include in the TAF.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 425 AM CST Sun Feb 1 2026
A Small Craft Advisory is in effect for all western Lake
Superior nearshore waters until this afternoon and evening.
Southwest winds will gust up to 30 knots this morning, creating
waves of 2 to 4 feet in ice free areas, particularly along the
North Shore and around the Apostle Islands. Winds will diminish
and shift northwest by tonight.
