.DISCUSSION...
Issued at 418 AM CST Sat Nov 29 2025

Surface analysis shows a low pressure system continuing to move
across Kansas and Oklahoma this morning, with warm air from the Gulf
advecting into the region. A wintry mix of precipitation continues
early this morning across the region, with snow, sleet, and freezing
rain/drizzle expected to continue. Early this morning, two bands of
snow have set up across eastern Nebraska and western Iowa, sleet,
light freezing drizzle, or freezing rain reported between the bands
and toward the Nebraska/Missouri and Nebraska/Iowa borders. The
drizzle has left several areas with a glaze of ice on surfaces.

The northernmost band is associated with an area of frontogenesis
and has been increasing in intensity and coverage over the past few
hours. The band currently extends from Beaver Crossing and
Rising City through Valley up to Harlan and Tekamah. This band
will slowly move to the east while also filling in to the south.
This will eventually result in a transition from the freezing
drizzle to snow for the Omaha metro area. A second band of snow
extending from Wilber to Nebraska City to Shenandoah, Iowa has
also developed, associated with another area of frontogenesis.
Areas to the south of this band will continue to receive mixed
precipitation through the morning and possibly into early
afternoon. There is still some uncertainty in how much snow
areas south of the I-80 corridor will see due to transition time
with precipitation type. For areas along and south of a line
from Lincoln to Clarinda, 1 to 3 inches of snow are possible
through tonight. An isolated rumble of thunder may not be
entirely out of the question with the southern band as well.

Heading into the afternoon, precipitation is expected to taper off
from west to east. Most of the precipitation should be out of
Nebraska by 8pm and out of our Iowa counties before midnight. Winds
gusting as high as 35mph on the back side of this storm system will
cause some blowing snow across the region; however, the strongest
winds will not be co-located with the heavier snowfall. This will
limit the potential for blizzard conditions; however, the blowing
snow may result in some reductions to visibility and travel
difficulties.

The forecast remains on track with the highest snowfall amounts (5-7
inches of additional accumulation) occurring in the Harlan and
Missouri Valley areas, with lesser amounts heading to the west.
Areas south of I-80 may still receive up to around a tenth of an
inch of ice accumulation by the time this storm system has passed.
Expect difficult travel conditions through the day, with things
improving overnight into Sunday.

Bundle up if you plan on heading out the door Saturday night into
Sunday. Lows by Sunday morning will bottom out in the single digits
for areas north of Highway 92 and the low to mid-teens for areas
south. Wind chill values will fall to the single digits below zero
for most of us, with a few single digits above zero in extreme
southeastern Nebraska. Sunday high temperatures will be fairly cold,
reaching the teens for areas along and north of a line from Harlan,
Iowa to Columbus, Nebraska. Monday morning will be cold as well with
highs in the single digits to around 10 degrees for Lincoln and
areas north. Areas toward the Kansas/Nebraska/Missouri border can
expect temperatures in the low teens to around 15 degrees. Wind
chills will be mainly in the single digits.

Monday morning, a mid-level shortwave trough will cross central and
southern Kansas, bringing a 30-60% chance for some snow to eastern
Nebraska/western Iowa. Unlike the current storm, Monday`s event is
not expected to be mixed-phase precipitation, and should be all
snow. SLR values are currently forecasted to range from around 16:1
to 18:1, resulting in more of a powdery snow.

Tuesday through the end of the forecast period, northwest flow sets
up over the region. Expect some slightly warmer temperatures with
highs returning to the mid-20s to mid-30s for Tuesday and Wednesday.
Expect a cool down again Wednesday night/Thursday morning, with lows
in the single digits above and below zero. Thursday`s high
temperatures will struggle into the teens for western Iowa and the
teens to low 20s for eastern Nebraska.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1143 PM CST Fri Nov 28 2025

IFR to MVFR ceilings and visibilities are observed at the start
of this TAF period along with a wintry precip mix. The wintry
mix will linger longer across KLNK, while a slightly earlier
change over to snow is expected at KOFK and KOMA. Ceilings and
visibilities may reach LIFR at times within any snow showers.
Winds will also be of concern, switching to the north northwest
with gusts of 25 to 35 kts expected late Saturday morning into
the afternoon hours at all three terminals. These winds may
result in areas of blowing snow further reducing visibilities.
Visibilities should improve to VFR sometime after 21 or 22z,
while snow should largely exit the area by 00z Sunday. May still
see lingering MVFR ceilings toward the very end of the TAF
period.
