.DISCUSSION...
Issued at 1258 PM CST Wed Nov 26 2025

Light snow persists across western Wisconsin as the 992mb sfc low 
pressure treks across the Upper Peninsula of Michigan. Conditions 
have dried out, but remain breezy across Minnesota. Patchy blowing 
snow has been observed so some isolated travel impacts cannot be 
ruled out. It has been quite the shift from Fall to Winter over the 
last 24 hours, but it's been well advertised. Temperatures remain in 
the twenties this afternoon with temperatures cooling into the upper 
teens and lower 20s overnight. Skies remain cloudy into Thanksgiving 
day, but the winds relax overnight as the low pressure continues 
northeastward into Canada. Thanksgiving day will be similar to today 
without the wind element. Highs in the upper 20s with mostly cloudy 
skies but nw winds around 10 to 15 mph. Friday will be similar with 
a few peaks of sunshine possible Friday morning ahead of our next 
organized system.

Friday night through Sunday... this period will bring a long 
duration snow storm out of the Plains and into the Midwest. An 
initial band of snowfall develops upstream over the Dakotas on Friday 
driven by WAA running into the cold air, promoting a region of FGEN 
& forcing. This band of snow will move into SW MN Friday evening and 
slowly turn eastward Friday night as the sfc low takes shape over 
the Plains. The Plains low will move into Missouri/Iowa by Saturday 
& precip blossoms over the Midwest. Model solutions diverge on the 
exact direction from here with some models like the ECMWF taking the 
sfc low feature into NW Indiana while the GFS or ECMWF AIFS bring it 
into S WI. Snowfall over S MN will be likely -  but to what extent 
remains uncertain. This event will likely be a light snow event with 
moderate bursts over 24 to 36 hours for portions of S MN. Event 
totals could very well be several inches when it's finished. The 
h700 low position varies with the stronger/snowier solutions for 
MN/WI (MPX CWA) further NW from the sfc low. The weaker, drier 
solutions are more vertically stacked and limit the forcing that 
overrides the inverted sfc trough feature. Either solution we'll 
likely see light snow Saturday across much of the region but how 
much will need to pump the brakes. There is high enough confidence 
to say the highest amounts of snow will likely fall along & to the 
south of the I-90 corridor with this event. The uncertainty is how 
much moisture/forcing extend north of there. This set up is one 
where I'd like more guidance under my belt before making a decision 
on potential winter headlines as the heaviest precip occurs along 
our border region & we're still 60 hours out from the start of any 
light precipitation. Snow character will likely be 15 to 18:1 SLRs 
or a more light & fluffy snow vs wet cement. Winds look like a non-
issue with speeds at or below 10 mph for the most part. This should 
make blowing snow a non-factor. 

Behind our system comes a potent wave of cold air to start the work 
week. High temperatures struggle to warm into the mid teens with 
lows at or below zero Sunday and Monday night. We'll gradually warm 
up into Wednesday when there is a signal for another system. This 
system appears to be a more traditional Alberta Clipper that'll 
track through and produce a quick hit of light/fluffy snow. We'll 
take this one event at the time but an active stretch of Winter 
weather is ahead of us as we begin the holiday season.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 512 PM CST Wed Nov 26 2025

Stratus will stick around through the period, with some lifting
and/or scattering to VFR expected at most sites tonight into
tomorrow morning. Ceilings will generally hover around the 3000
ft threshold through the period, but do look to drop back below
3000 ft by tomorrow afternoon.

Northwest winds are diminishing this evening but gusts of 25-30
kts are still likely at times for the next few hours. Wind 
gusts generally diminish to around 20 kts by midnight & become 
more sporadic, remaining fairly steady between 10-20 kts 
through the day tomorrow.

KMSP...Ceilings will hover right around the 3000 ft MVFR/VFR
threshold through the period, but chances look more likely for
VFR ceilings tonight into tomorrow morning. SOme scattering out
even looks possible for a few hours tomorrow morning before
ceilings likely fill back in & drop below 3000 ft around noon
tomorrow. Northwest winds gusts up to 25-30 kts for the next
hour or two, and then generally remain steady around 10 kts
through the rest of the period with sporadic gusts around 20
kts.

/OUTLOOK FOR KMSP/
FRI...VFR. Chc MVFR/-SN late. Wind W 5 kts. 
SAT...MVFR/IFR -SN likely. Wind ENE 10-20 kts.
SUN...VFR. Slight chance AM snow. Wind WNW 10-15 kts.
