.DISCUSSION...
Issued at 319 AM CST Wed Feb 18 2026
A powerful and complex winter storm remains centered over
central Minnesota this morning, continuing to lash the
Northland with a variety of dangerous hazards. Strong mid- to-
upper level atmospheric forcing and frontogenesis are
maintaining high precipitation rates. In addition, this has lead
to showers that are convective, leading to thundersnow this
morning. Heavy snow is the primary concern for most of northeast
Minnesota, while a transition from rain and freezing rain to
snow will occur across northwest Wisconsin later this morning
and afternoon as the cold front moves through.
The most extreme conditions are focused along the North Shore of
Lake Superior. Strong easterly winds have already gusted up to
65 mph this morning. These winds are interacting with the local
terrain and picking up moisture from the lake, significantly
boosting snowfall rates to nearly an inch per hour at times.
While most of the region will see an additional 4 inches of snow
today, the North Shore ridge could see an additional 12 to 18
inches. Visibility in these blizzard and storm warned areas
will frequently drop to zero due to the combination of heavy
falling snow and significant blowing snow. As the low pressure
system tracks toward the northeast today, winds will slowly
decrease and veer to the northwest, but hazardous conditions
will linger well into Thursday. Snow that falls today will also
be wet and heavy particularly in areas south of the Iron Range,
with snow to liquid ratios below 10. Caution should be taken
when shoveling snow. Travel remains treacherous across the
entire region this morning and throughout today from the
differing conditions across the region. In the Brainerd Lakes
area and throughout much of northwest Wisconsin, an initial
glaze of ice from freezing rain and sleet is being covered by
fresh snow, hiding very slippery surfaces. In the Twin Ports, a
mix of heavy snow and high winds will continue to make the
morning and evening commutes very difficult.
We are watching a second Colorado low expected to develop
quickly behind this current system. This second storm will take
a more southerly and easterly track, moving through northern
Iowa/Illinois into Wisconsin and Michigan. While the core of
the strongest weather will stay to our east, the Minnesota
Arrowhead and northwest Wisconsin could see locally heavy
snowfall and an additional up to 5 inches of snow early Friday
morning. Following this second system, cold air moving in from
the northwest will keep light snow showers in the forecast
through Sunday evening. An active weather pattern appears likely
to persist through late next week, but confidence is low of any
one solution of when/where precipitation will occur through
next week.

.AVIATION /12Z TAFS THROUGH 12Z THURSDAY/...
Issued at 532 AM CST Wed Feb 18 2026
A strong winter system is leading to widespread reductions in
ceilings and visibilities from wintry precipitation. This is
expected to continue through the morning morning, with some
terminals lifting to MVFR/VFR by late Wednesday afternoon.
Slow, steady improvements in conditions will be seen throughout
the afternoon as the system passes through the Northland and
snow becomes lighter. Confidence was not high enough to include
in the TAF, but light snow showers could persist into tonight
with MVFR ceilings and visibility to accompany it. LLWS is
included as well with up to 55 kts of shear through the early
morning. Winds will slowly decrease out of the east and veer to
the southwest throughout the TAF period. Gusts up to 40 kts for
all and up to 55 kts for DLH are expected through the night.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 319 AM CST Wed Feb 18 2026
A Storm Warning is in effect for the North Shore and Twin Ports
waters through this afternoon, with a Gale Warning for the
South Shore. Expect easterly winds gusting to 50 knots and waves
building to 8 to 11 feet, with occasional heights up to 14
feet along the North Shore. Wind gusts up to 45 kts are expected
along the South Shore, though waves will be small along the
shoreline as winds will be offshore for most of today. Apostle
Islands, however, could see waves of 8 to 11 ft as well.
Conditions will remain hazardous for small craft into Thursday
as waves slowly subside.
