.DISCUSSION...
Issued at 104 PM CST Wed Feb 25 2026
Below normal temperatures will continue today and tonight. A
warm front arrives tonight, spreading a band of light snow
across the Northland. Most areas will see less than an inch of
accumulation through Thursday morning. As the front passes,
temperatures will warm significantly on Thursday, reaching the
mid 30s to lower 40s. However, lingering moisture in the
Arrowhead may create a period of light freezing drizzle or mist
late Thursday morning and afternoon, potentially leaving a thin
glaze of ice on elevated surfaces.
The most impactful weather arrives Friday. A low pressure
system moving through Manitoba and Ontario will drag a stout
cold front through the Northland. Ahead of the front,
temperatures will warm into the 40s for many locations. As the
front cross over the region Friday afternoon, localized snow
squalls may (20-40% chance) develop, especially from the Iron
Range to North Shore and northward. These bursts of heavy snow
can reduce visibility to less than one quarter mile over very
short distances and lead to very hazardous travel conditions.
Southwesterly winds will quick shift westerly and increase in
speed behind the front, then further shift to northwesterly.
The strongest gusts, potentially reaching 60 mph, are forecast
for the North Shore. Elsewhere, expect gusts of 35 to 45 mph.
Temperatures will rapidly decrease Friday night, which may lead
to a flash freeze on roadways of any snowmelt to freeze rapidly.
Much colder air settle in for the weekend with highs only in
the from 8 to 18 F on Saturday. Expect wind chills from -10 to
-25 F Friday night as the cold settles in and combines with
lingering gusty winds. Even under calm winds Saturday night, the
air temperatures will still lead to seasonably very cold
conditions. Air temperatures of -10 to -20 F are forecast north
of US Hwy 2 and -5 to -10 F south of US Hwy 2. Sunday remains
below normal for temperatures, but not to the extent of
Saturday. Another gradual warming trend begins early next week.

Issued at 1115 AM CST Wed Feb 25 2026
Outside of MVFR ceilings along the South Shore, VFR conditions
are largely expected through the daylight hours today. Going
into this evening, a warm front lifts across the area late
tonight into Thursday morning. This will bring a period of very
light snowfall to most terminals. A few hour period of IFR
visibility within the heaviest snowfall in far northern
Minnesota along and north of US Hwy 2. After most snowfall exits
the area tomorrow, a few hour period of mist/drizzle may occur
in the Arrowhead and potentially affect KDLH and KHIB for a few
hours after 12Z Thurs. Winds become southwesterly post warm
frontal passage Thursday daytime.
