.DISCUSSION...
Issued at 258 AM CST Tue Feb 10 2026
The wintry system that brought recent precipitation to the
Northland is currently exiting to the east, but we are not quite
done with the snow just yet. Cold air advection on the backside
of the departing low will lead to steepening lapse rates and
enough atmospheric instability to support horizontal convective
rolls. These features will manifest as scattered bands of snow
and flurries across the Iron Range and points northward
throughout the day. While there is some disagreement in the
soundings regarding the depth of moisture and forcing within the
dendritic growth zone which would indicate freezing drizzle
rather than snow, experience with these post-frontal setups
suggests the atmosphere will likely squeeze out some light
snow. However, because these snow showers will be battling dry
air at the surface, additional accumulations are expected to be
no more than a trace in most locations. Additionally, gusty
northwest winds are expected from the tight pressure gradient on
the back side of the system, and will decrease overnight tonight
as the system continues off to the east.
As we move into the middle of the week, a strong area of high
pressure will settle over the region. This high has already
forced a weak shortwave previously forecast for Thursday to
track much further south, effectively removing any chances for
precipitation in the Northland Thursday afternoon and evening.
We will find ourselves in the western warm sector of this high
pressure system for the remainder of the work week. This shift
in the pattern will usher in a period of quiet weather with
temperatures trending well above seasonal normals. Daytime highs
will likely climb above freezing across much of the area,
leading to a daily freeze-thaw cycle that could make untreated
surfaces like sidewalks and secondary roads slippery during the
overnight hours.
Looking ahead to the weekend, the next opportunity for
precipitation arrives Saturday into Sunday. A weak shortwave is
projected to move through the region, but it currently lacks
significant moisture, suggesting only light accumulations at
best. There remains considerable model uncertainty regarding the
exact track and timing of this system this far out. Beyond the
weekend, the pattern may become more active as a broader
troughing signature develops over the western United States, but
for now, the Northland can expect a relatively dry and mild
stretch of weather.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 518 AM CST Tue Feb 10 2026
MVFR ceilings linger on the back side of a departing low
pressure system. Gusty winds out of the northwest with values up
to 25 kts will last into the late afternoon for all terminals.
With cold air advection leading to lift in the Iron Range and
the Borderlands could lead to some convective snow showers,
particularly for INL and HIB. These snow showers may lead to
MVFR/IFR visibilities for a brief period with the showers, and
are possible on and off throughout the late morning and
afternoon. Confidence isn`t high enough to include in a TEMPO,
so have PROB30s set for now.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 258 AM CST Tue Feb 10 2026
A Small Craft Advisory is currently in effect for most of the
Western Lake Superior nearshore waters. Northwest winds will
gust between 20 and 30 knots today before gradually subsiding
late tonight and early Wednesday. Significant wave heights will
generally remain 2 feet or less near the shore due to the
offshore wind direction, though areas further out toward the
Apostle Islands may see slightly higher chop. Conditions will
improve by Wednesday afternoon as high pressure builds in.
