.DISCUSSION...
Issued at 112 PM CST Thu Feb 26 2026
Very light snowfall may skirt the Minnesota Borderlands tonight
ahead of an incoming cold frontal passage slated for Friday late
morning to late afternoon. This cold frontal passage has moved
up in time by a few hours in guidance trends over the last day.
Winds will intensify rapidly by midday Friday. West winds will
gust between 40 and 50 mph for northern Minnesota along and
north of US Hwy 2 and Douglas and Bayfield counties into the
evening hours. Wind Advisories were issued this afternoon for
this part of the Northland covering Friday late morning to late
evening hours. The strongest winds are expected along the North
Shore Friday mid-afternoon to late evening when gusts to 60 mph
gusts are forecast in southern Cook County. This magnitude of
wind gusts may result in tree limbs being knocked down and cause
sporadic power outages. A High Wind Warning is in effect for
southern Cook County all of Friday afternoon and evening.
The threat of snow squalls has continued to move further
northward over the last 24 hours. The chances of snow showers
and embedded isolated snow squalls is largely limited to Friday
afternoon and early evening right along the International
Border. The deepest pool of low-level instability is progged in
high res and global guidance to reside just over the Border into
Ontario. A few diurnally-aided snow showers could still create a
quick burst of localized heavy snowfall in Borderland places
though Friday PM.
The timing of flash freeze potential concerns has also moved up
in time by few hours compared to the forecast 24 hours ago. This
also promotes an earlier onset of freezing temperatures now
into the mid to late afternoon for areas of the Iron Range
northward. By early Friday night, expect most areas that were in
the 40s that afternoon to be observing temperatures in the low
teens to upper single digits above zero.
While winds do decrease Midnight afterward Friday night,
lingering gusts and that seasonably cold airmass creates
forecast wind chills by Saturday early morning of 10 to 25 below
zero. Even colder air temperatures are very likely Saturday
night into Sunday morning. Expect Sunday morning low
temperatures of 10 to 20 below zero along and north of US Hwy 2
and 5 to 10 below zero south of US Hwy 2.
A gradual warming trend returns next week under a quiet weather
pattern through mid next week. There are hints of a possible
southwesterly track system moving somewhere through the Midwest
next Wednesday PM into Thursday.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1134 AM CST Thu Feb 26 2026
Last of the warm front snow showers exit northwest Wisconsin
over the next couple of hours. Lingering MVFR sky cover in far
northern Minnesota will persist though into the late afternoon
hours and potentially early evening. Another few hour period of
light snowfall is possible tonight for northern Minnesota with a
PROB30 mow in place for the KINL TAF site. Ahead of an incoming
cold front Friday midday to afternoon, a period of low level
wind shear is expected late tonight into Friday morning before
gusty westerly winds mix out from 15 to 18Z Fri.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 1146 AM CST Thu Feb 26 2026

morning under increasingly gusty southwesterly winds. Dangerous
conditions develop Friday afternoon on Western Lake Superior.
West winds will increase to Gale force for most nearshore
waters. Storm Force gusts to 50 kt are likely from Taconite
Harbor to Grand Portage. These conditions taper in coverage and
magnitude late Friday night with ramp down Small Craft
Advisories very likely being needed after the Warnings are let
go late Friday. Northwest winds over the western waters last
into Saturday daytime, but forecast around or less than 20
knots. Heavy freezing spray will rapidly accumulate on vessels
Friday evening through Saturday morning as Arctic air arrives.
Waves will build to 6 to 11 feet Friday PM.
