.KEY MESSAGES...

- Pockets of heavy snow showers will persist into this evening
  mainly south of a line from Aitkin to Moose Lake to Bayfield.
  Visibility of 1/2 to 1/4 mile is likely at times in the
  heaviest snow showers. Rapid snow accumulation on roads is
  likely in those snow showers.

- Moderate to heavy lake effect snow is expected this afternoon
  and overnight in the higher elevations of Iron and Ashland
  counties, with 3 to 8 inches of new snow possible. Travel will
  be difficult at times in the South Shore snowbelt due to
  slippery roads and greatly reduced visibility.

- A much quieter and unseasonably warm week is ahead, with highs
  reaching the 40s and even 50s by Friday.

.DISCUSSION...
Issued at 1248 PM CST Sun Nov 9 2025

It certainly feels like winter across the Northland as a cold
front has brought a polar airmass into our region. This cold air
moving over the relatively warm waters of Lake Superior will
fuel bands of moderate to heavy lake effect snow this afternoon
and overnight. The greatest impacts will be along the South
Shore, especially in the higher terrain of northern Iron and
Ashland counties, where an additional 3 to 5 inches of snow is
possible. Because of this, a Winter Weather Advisory remains in
effect for Iron and Ashland Counties until Monday morning. Travel
within these snow bands could become very difficult. Snowfall
rates may exceed one inch per hour at times, which will quickly
lead to slippery roads and dangerously low visibility. For the
rest of the area outside of the snow belt, only light snow
showers and flurries are expected. Most of us will see very
little accumulation, likely less than an inch.

This burst of winter weather will be short-lived. The snow is
expected to wind down for everyone on Monday as this weather system
moves away and drier air filters into the Northland. After that,
a much quieter and milder pattern is set to take over for the
entire week. A noticeable warming trend will begin on Tuesday,
with high temperatures climbing back into the mid-30s and 40s. By
Friday, it will feel much more like fall again, with unseasonably
warm highs expected to reach the mid-40s to low 50s for most of
the area. There is only the smallest of chances for precipitation
Tuesday until next weekend.

After this brief cold snap, no snowy systems are in the forecast
as the weekend system looks like plain rain.

.AVIATION /00Z TAFS THROUGH 00Z TUESDAY/...
Issued at 546 PM CST Sun Nov 9 2025

Heavy snow showers will continue to advance south-southeast
this evening. HYR will experience several heavier snow showers
before 10.03Z. 04W, RZN, ASX and PBH will also see heavy snow
showers. Lake-effect snow will persist over northwest Wisconsin
through tonight and should remain east of HYR. Conditions
gradually improve to VFR everywhere Monday as high pressure
advances eastward with ceilings scattering out. Light snow
showers and flurries will persist through this evening elsewhere
until skies begin to clear. Brief periods of MVFR/IFR
visibility are possible if a heavier snow shower passes over the
terminals. LLWS may become a concern at INL and BRD Monday
evening after 11.00Z.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 1248 PM CST Sun Nov 9 2025

North to northwest winds of 10 to 20 knots with gusts up to 30
knots are expected on Lake Superior this afternoon. These winds
will build waves to 2 to 5 feet, especially along the South
Shore and near the Apostle Islands. Small Craft Advisories are
in effect through tonight. Visibility may be poor at times near
the South Shore due to lake effect snow showers. Winds will
diminish early Monday. By Tuesday, winds will shift to the
southwest and increase, likely requiring new Small Craft
Advisories into Wednesday, when even stronger westerly winds are
possible. There is some potential for westerly gales Wednesday
as model gusts are trending upwards as a strong pressure
gradient develops from a low crossing Hudson Bay with high
pressure over the Dakotas.

Forecast Discussion at weather.gov/mqt.
