What forecasters said that day
The local office's own words before this storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Marquette, MI wrote its last area forecast discussion before this storm warning went out at Feb 26, 5:59 AM EST, 5 hours 26 minutes earlier. Its key messages:
- A weak clipper system will bring another round of light snow to much of the area today, but expected snowfall amounts will only be around an inch or less in most locations.
- After a mild day on Friday, a strong cold front on Friday night will bring much colder air back into the area along with a period of strong winds, particularly over the Keweenaw and near Lake Superior, where there is a 50-80% probability of wind gusts exceeding 45 miles per hour Friday afternoon into Friday night. There is a 50% chance of wind gusts exceeding 60 mph in the Keweenaw, where a High Wind Watch has been issued. Areas of blowing snow may restrict visibility in open areas.
- Seasonably cold temperatures are expected this weekend with highs in the teens and lows in the negative single digits.

.DISCUSSION...
Issued at 212 AM EST Thu Feb 26 2026
Broad troughing encompasses most of the CONUS early this morning,
with one branch of the jet from the Intermountain West into the
southern Plains to the mid-Atlantic, and another from the Canadian
Rockies to the northern Plains. The latter feature will continue
digging into the Great Lakes today, with poleward exit region
dynamics and modest isentropic lift provide forcing for ascent
today. Overall limited moisture and short duration of forcing should
limit accumulations to around an inch or less, although there is a
brief period where forecast soundings have modest lift within the
DGZ. 90 percentile snowfall is generally 2" or less of the NBM, so
totals should be fairly negligible compared to what we've seen over
the past couple of weeks. Onset time looks to be 12-18Z from west to
east.
A stronger WNW jet max emerges off the Canadian Rockies
tonight/Friday with a compact, vigorous vort max going negatively
tilted over central Ontario Friday. The surface reflection of this
wave is forecast to be down in the mid/lower 980s (mb). Although it
will be well to the north, the resulting wind field will advect
warmer air into the region on Friday, with highs ranging from the
upper 30s east to mid-40s west. This warm spell will be short lived
as a strong cold front will cross the UP Friday afternoon into
Friday night. Strong winds will be the main threat with this frontal
passage, as forecast soundings suggest dry air at low levels
negating precipitation potential. These soundings also show very
impressive mixing heights as cold advection aloft steepens lapse
rates, as high as 700 mb from the 00Z NAM at CMX (this is likely
overdone, but the GFS still mixes up to 800 mb). This means that the
mixing should have no trouble tapping into 35-50 kt winds at 925 mb.
925 mb winds of 45-50 kt over the Keweenaw on the 00Z LREF are at 99
percentile of climatology here. On the CAM side, the 00Z HRRR does
have an area of 50kt wind gusts over the Keweenaw Friday afternoon
and evening. With all those factors in mind, there is enough
confidence for a High Wind Watch for the Keweenaw for the potential
of 50 kt wind gusts Friday afternoon into the evening. The core of
the strongest winds will be in roughly the north half of the UP, so
that should confine the potential for advisory-level (40 kt) gusts
outside of the Keweenaw to the Lake Superior shoreline, but the deep
mixing should result in widespread 30-40 mph gusts over most of the
UP. This could result in visibility issues due to blowing snow in
open areas, however there is uncertainty if the mild temperatures
will render the snow less blowable.
The other story with this frontal passage will be the rapidly
plummeting temperatures. After highs in the 30s and 40s Friday,
lows Friday night will be in the single digits and teens, with
wind chills 0 to minus 10. 850 mb temps bottom out at -20 to -25
over the weekend, which is in the 5 to 10 percentile per the
LREF. While the probability of reaching Cold Weather Advisory
criteria is low, we can expect highs in the teens and lows in
the negative single digits over the weekend. Saturday night
looks good for radiational cooling, with up to a 40% chance of
lows below -10F over the interior. Some light lake effect snow
in the NW belts is also expected, with negligible amounts. A
modest warming trend is forecast for early next week, with low
probability of impactful weather at this time.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 558 AM EST Thu Feb 26 2026
Light snowfall moves over the terminals today as a weak shortwave
low traverses the region. Expect conditions to deteriorate to
IFR/MVFR over the terminals during most of the daylight hours today
thanks to the light snowfall, before improving to MVFR/VFR after the
snowfall ends this evening (improvement to VFR for SAW this evening
will depend on whether the clouds scatter out or not).
While not expected, there is the potential for some LLWS to develop
over the terminals late tonight/early Friday morning as a LLJ begins
to push into the Upper Midwest and U.P.

increase through the day Friday, with a high probability of gales
developing over the entire lake Friday afternoon into Friday night.
As winds shift westerly and colder air arrives behind a cold front
tied to a strong low crossing Ontario, strong winds will mix down,
with a 30-50% probability of storm force gusts Friday afternoon into
Friday night for the central and eastern portions of the lake. A
Storm Watch will be issued to address this potential. Heavy freezing
spray will also develop Friday night over the entire lake, lasting
into Saturday. Winds will fall below gales Saturday afternoon and
continue diminishing through Sunday as high pressure builds in.
