.DISCUSSION...
Issued at 208 PM CST Sat Dec 6 2025

Tonight and Tomorrow...

An upper-level shortwave trough diving south across the High Plains
has spun up a surface low now tracking across north-central Nebraska
as of early afternoon. Ahead of this system, warm air advection and
frontogenesis have produced a north-south oriented shield of
precipitation extending from southeast SD/northwest IA southward,
gradually decaying as it approaches southeast NE. Precipitation type
has been variable, with temperatures ranging from the upper 20s in
the far northern CWA to the upper 30s across southeast NE/southwest
IA. Southwesterly winds gusts of 20-25 mph has also kept wind chills
in the 20s to low 30s. Snow has been the predominant precipitation
type across northeast NE, where 1 to 3 inches of accumulation is
expected, though most of this has already fallen. This area has seen
the most efficient snowfall rates, approaching 1 inch per hour,
thanks to strong isentropic lift along the eastern NE/SD border.

Farther south, a transition zone has set up roughly along a Columbus-
Wahoo-Omaha line, where a light rain/snow mix has been observed.
South of this corridor, precipitation has fallen primarily as
spotty, light rain. Any accumulating snow in this transition zone
will likely peak at a dusting. Precipitation will exit from west to
east through the rest of the afternoon and early evening as the
surface low tracks southeast into northwest Missouri. A Winter
Weather Advisory continue for portions of northeast NE and western
IA through the afternoon. As temperatures fall this evening,
refreezing of residual moisture may create slick spots, so use
caution if traveling or walking on untreated surfaces.

Behind the departing low, cooler air will settle in, dropping
overnight lows into the teens, with single digits likely across
northeast NE and northwest IA. Wind chills will fall into the single
digits above and below zero, with values as low as five below across
the far northern CWA. Persistent CAA and lingering cloud cover will
hold Sunday`s highs to the teens and mid-20s. A brief ridge of
surface high pressure will move in early Sunday before a mid-level
shortwave crossing the northern High Plains pushes a warm front into
the region during the mid-day. This may bring a brief round of
flurries across northeast Nebraska Sunday afternoon (15-30% PoPs).
QPF remains minimal, generally under 0.05", so accumulation and impacts
are not expected.

Monday and Beyond...

An active upper-level pattern will persist through the work week,
bringing fluctuating temperatures and a chance for late-week
precipitation. The work week will kick off with a chilly Monday
morning, as lows dip into the teens and wind chills drop to the
single digits. Southerly low- level flow will help Monday`s
highs rebound into the 30s and low 40s, with a more pronounced
warmup Tuesday as temperatures climb into the 40s and even low
50s across east- central NE. This warmer day will also feature
breezy northwesterly winds, with gusts of 25-35 mph.

A shortwave passing to our northeast will sweep a cold front through
the region late Tuesday, knocking highs back into the 30s for both
Wednesday and Thursday. Precipitation chances return late Wednesday
into Thursday as a mid-level trough advances into the northern
Plains and and sends a ribbon of vorticity across the area. Current
PoPs peak near 30%, though GEFS and EPS/EPF-AIFS ensemble guidance
continues to show a wide spread in placement and intensity of any
associated snowfall at this range. One aspect with higher confidence
is the cold air that follows. Temperatures will tumble behind the
system, with Friday`s highs only reaching the teens and 20s.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1149 PM CST Sat Dec 6 2025

IFR conditions have expanded south to KOMA and KLNK, and cigs
have lowered to LIFR at KOFK. Expect reduced conditions to hold
overnight with winds out of the north. We`ll see cigs start to
lift between 13-15Z on Sunday, with winds starting to relax a
bit to around 08-10kt. We`ll see clouds gradually breaking up
through the morning from northeast to southwest, with MVFR cigs
more likely holding through the day at KOFK. This will bring
VFR conditions to KOMA and KLNK by 16-17Z. Clouds from the west
will spread back eastward toward the evening, with some
uncertainty in how low they will be when they arrive at KLNK and
KOMA around 00Z. Model spread has cigs anywhere from FL050 to
FL015, but greater confidence (60%) is in VFR cigs probably
around 3500-5000 ft. At the same time, winds will be shifting to
southeasterly.

.KEY MESSAGES...

- There could be scattered snow showers (20-30% chance) Sunday
  afternoon mainly across south central Nebraska with better
  chances north of I-80. This would mainly be trace amounts of
  snow if anything.

- Colder on Sunday with highs in the 20s (northeast) to mid 30s
  (southwest). Just a 1 day cold snap.

- Above normal temperatures return Monday and Tuesday with highs
  mainly in the upper 40s to mid 50s Monday, mid 50s to lower
  60s Tuesday.

- A series of clipper systems will swing through beginning
  Tuesday night bringing progressively colder air back into our
  region. There could be some light snow Wednesday afternoon
  into Wednesday night, but currently not looking like it will
  amount to much.

.DISCUSSION...
Issued at 218 PM CST Sat Dec 6 2025

Tonight...

A surface area of low pressure will slide off to our southeast
and colder air will filter back into our region with briefly
gusty northerly winds this evening behind the low. Any
precipitation with this clipper system will be well to our
northeast across far northeastern Nebraska this evening. We
expect dry weather across our forecast area.


Sunday...

This will be a one day cold snap behind tonight`s clipper system
with the coldest air across our northeast and especially east of
our area. Our southwestern areas will only get a glancing shot
of this cold air. Northeastern Nebraska will likely only see
highs in the teens while our northeastern zones should reach
into the 20s, and our southwestern areas could make the mid 30s.

There is a chance for light snow Sunday afternoon with warm air
advection as 850 mb temperatures start to climb from west to
east. Will see at least increasing clouds and forecast models
vary on snow chances, but the predominate model solution seems
to be trace amounts of light snow showers across our northern
counties, mainly north of I-80. Did introduce small snow POPs
of (20-30%) into the forecast. Again, only expecting trace
amounts of snow for those that do catch a little snow.


Monday through Tuesday...

This will be a nice warm up especially Tuesday with many areas
seeing highs over 60 by Tuesday afternoon. We are essentially in
a northwest flow pattern and warmer air pushes in from the west
before the next clipper can blast us with another round of cold.


Wednesday through Saturday...

Warming periods typically don`t last long this time of year and
that will be the case as we end the work week and move into
next weekend. The next clipper system comes in from the
northwest Tuesday night and could bring some light rain or snow
to the forecast area by Wednesday afternoon into Wednesday
night. At this point it doesn`t look like a big snow maker for
our area but it`s still a long ways off with a wide envelope of
model solutions at this point in time. What is most likely at
this point is that gradually colder air will work back into the
area late week into next weekend.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 545 PM CST Sat Dec 6 2025

For KGRI/KEAR Airports:

Tonight: Expect MVFR to borderline IFR CIGs to push in from the
N later this evening (generally 02Z to 04Z) along and behind an
Arctic cold front. This front will also bring some breezy Nrly
winds overnight, gusting 20-25kt. The best chance for IFR CIGs
looks to be at GRI, but EAR will also be close. May hover right
near the threshold towards dawn, so introduced some TEMPO MVFR
CIGs after 09Z to show IFR may not be a lock. Confidence: Med.

Sunday: Stratus will likely persist much of the morning, with a
general trend from IFR/MVFR to primarily MVFR CIGs. There could
be some flurries or very light snow during the afternoon, but
doesn`t appear organized enough at this time to meaningfully
reduce VSBYs or CIGs. Winds will weaken through the day and turn
more NErly for the afternoon. Confidence: Med.
