.DISCUSSION...
Issued at 258 AM CST Thu Jan 15 2026
Currently over the Northland, a surface ridge axis extends
northeastward through the region, with low stratus off western
Lake Superior spreading over portions of northwest WI with
light snow/flurries falling. To our west, mid to high level
clouds are moving into north central MN, ahead of the next
clipper. A surface low is centered well to our north over
northern Manitoba, with warm front extending southward into the
Central Plains. The ridge axis quickly shifts to the east this
morning as a shortwave advances across the Canadian Rockies and
into the Plains. This will push the warm front into the
Northland, ahead of the southeastward moving surface low.
Recent CAMs show a band of snow showers developing up stream and
moving SSE into the Northland later this morning, associated
with significant pressure falls and a band of frontogenesis
ahead of the trough, and steep lapse rates and saturated columns
aloft. This could lead to locally heavy snow showers, with
snowfall rates of 0.5-1.0 inch per hour, and sudden reductions
in visibility. There is still dry air at the surface that we
need to overcome, and uncertainty amongst model guidance on if,
and where, these heavier snow showers are most likely. Will
likely cover the potential impacts with a SPS this morning, and
assess trends once activity develops upstream.
There is a low chance of freezing rain/sleet mixing in at times,
particularly across the Brainerd Lakes area, as a warmer nose
nudges in from the southwest behind the warm front while a
pocket of drier air pushes across the Red River Valley ahead of
the shortwave. Other than a very light glaze, no ice
accumulations are expected. The warm nose and drier air is not
as pronounced further northeast, and expect all snow east of the
US 53 corridor. Along the North Shore, with increasing
southwest winds, there could be some enhanced snowfall from
Tofte northward this afternoon.
As the shortwave and cold front arrive tonight, lapse rates
steepen again and could see another round of heavier snow
showers this evening that could quickly reduce visibilities with
a 20-30% chance of snowfall rates of 0.5-1.0 inch per hour.
Another SPS or advisory might be needed. Otherwise, as the
shortwave closes off over the Great Lakes, light snowfall will
persist over the Northland into Saturday. Totals though Saturday
morning will approach 3-6 inches for locations north of US-2.
Locally higher amounts are expected over northwest WI, due to
lake effect showers.
The first of two cold air surges arrives Friday night. Weekend
highs will be 10 to 20 degrees below normal with readings in the
single digits either side of zero. Dangerous wind chills are
forecast Sunday night into Monday morning as another cold front
dives southward across the region. Colder than normal temps will
persist for much of the upcoming week and may drop well below
normal again next weekend.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 536 AM CST Thu Jan 15 2026
Outside of the South Shore snowbelt in north-central Wisconsin,
where low clouds persist, mid and high clouds stream across the
area ahead of the next weather system. An incoming clipper
system brings snowfall chances beginning this morning, through
the forecast period. A few heavier snow showers today could
bring sudden drops in vis with snowfall rates of 0.5 to 1.0 inch
per hour. Cannot rule out a period of SN/FZDZ that could lead
to a light glaze of ice on untreated surfaces. South to
southwest winds increase through the morning, with gusts up to
22kts, before veering to the west tonight. Cigs fall to MVFR
heights this morning, with IFR heights possible this afternoon.
&&
.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 258 AM CST Thu Jan 15 2026
Winds increase from the southwest this morning ahead of an
approaching clipper. Conditions will become hazardous with gusty
winds and building waves. Gusts of 25-30kts are possible in all
nearshore zones. Heavier snow showers are possible mid morning
into the afternoon, causing quick reductions in visibility. A
cold front will pass eastward across the water tonight and
Friday morning which will veer winds northwesterly. By late
Friday afternoon and early Friday evening wind and waves will
become hazardous once again and there is a 30-40% chance of
gales to 35 knots near Grand Marais to Grand Portage. Winds
gradually relax Saturday afternoon and evening.
