.DISCUSSION...
Issued at 243 PM CST Mon Dec 22 2025

A mild afternoon is well underway with filtered sunshine and
temperatures in the 30s to low 40s. Low pressure over northeast
Nebraska early this evening will lift northeast across the
Upper Midwest and bring a cold front southeast overnight. As the
low passes overhead, winds will become light and variable and
could promote the development of areas of fog. The fog will
likely dissipate as winds increase behind the cold front late.

High pressure will slide east along the Canadian border Tuesday.
Cold air advection is not expected to be particularly strong,
so Tuesday will be a bit cooler but there won`t be a bona fide
shot of arctic air with this front. The high will shift east
Tuesday night and allow winds to turn southeast again through
Wednesday. Another high across southern Canada will bring the
second act of winds shifting northwest for Wednesday night,
resuming southeast for Thursday. A stronger low pressure system
over South Dakota will allow these southeast winds to strengthen
and advect better low level moisture north. Considerable low
cloud cover should result and may also result in fog. The
overcast conditions and snowpack will limit how mild
temperatures will likely get and forecasted highs have decreased
a few degrees with the recent trend. The low will become an
inverted trough as it tracks east to the Great Lakes Thursday
night. While not overly impressive, some precipitation should
break out across northern and eastern MN. Warm temperatures
aloft will favor liquid and surface temps will determine whether
it hits the surface as rain or freezing rain. Similar to last
night, amounts will be light but could be impactful for Friday
morning.

A more substantial trough is forecast to dig into northern
Rockies/northern Plains Friday and then track east to the Great
Lakes Saturday night. Most of the precip with this system could
be confined to northern MN, but shifts are likely in the coming
days. The low pressure center could undergo strengthening
depending how the trough digs southeast. Strong high pressure
building south into the northern Plains behind it will usher in
another shot of arctic air Sunday and early next week. Then,
a quick moderating trend in temperatures back to above normal is
likely as zonal flow or slight ridging returns.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1151 AM CST Mon Dec 22 2025

VFR conditions will continue through the day with some potential
for lower cigs and patchy fog tonight. Confidence is not
particularly high, but it is higher toward EAU so included MVFR
cigs returning this evening. Southeast winds will become
west/northwest tonight behind a cold front.

KMSP...Can`t rule out some ground fog overnight, but winds
aren`t expected to decouple fully so the probability is low.
There is a low chance MVFR cigs will develop Tuesday morning, so
included a FEW mention for now.

/OUTLOOK FOR KMSP/
WED...VFR. Wind SE 5-10kts.
THU...VFR. Wind SE 5-10kts.
FRI...VFR, chc MVFR/IFR. Wind light/variable.
