.DISCUSSION...
Issued at 409 AM CST Thu Dec 4 2025

Single digit temperatures above and below zero are ongoing early
this morning for most areas. Stratus developed yesterday evening
over the southeastern part of Nebraska, which has helped limit some
of the radiational cooling others have experienced. A few locations
that were impacted by the lower clouds are still hanging on to the
double digits. Clouds are starting to move out; however, their
lingering presence has impacted potential low temperatures over that
area. Temps have been adjusted upward as a result. Thursday high
temperatures have also increased a degree or two in locations. Teens
and 20s are expected for much of the region with a few 30s
toward Knox, Boone, and Antelope counties.

A broad, mid-level trough will extend west to east from Montana to
New England, and south into the Blue Ridge Mountains (Virginia) over
the next several days. Northwest flow will be in place over the
Great Plains and Central High Plains, with a ridge just off of the
West Coast. A series of embedded shortwaves will move through the
larger pattern, bringing a couple of chances for precipitation.

After a brief reprieve from the cold on Friday (highs in the 30s
with a few isolated 40s), the area gets hit with another storm
system. High temperatures are currently expected to be in the upper
20s to upper 30s on Saturday. Snow will move in from the north
Saturday morning with a 20-30% chance from I-80 northward, with a 40-
60% chance for areas toward Creighton and Winside. Snow chances
increase to 30-60% in the afternoon for areas toward I-80. This
system will exit the region Saturday night/Sunday morning from west
to east. Some accumulations will be possible, particularly for areas
north of the Platte River. Models handling of this system has
changed quite a bit from 24 hours ago, so continue to monitor the
forecast for additional changes as we come closer to the event.

Colder temps are expected Sunday as the shortwave exits the region.
Expect highs in the teens and 20s and lows in the single digits
above zero to around 10 degrees.

Another warm up into the 30s (a few low 40s possible) will arrive
Monday and Tuesday as the ridge over the Pacific shifts east.
Another weak disturbance will slide across the region on Tuesday,
bringing a chance for the northeastern portion of the area to get
clipped with a snow shower.

MVFR ceilings expected to stick around at OFK through the
afternoon, with guidance remaining persistent that it clears out
by this evening. Currently expect ceilings to stay west of LNK
and OMA, but will need to closely monitor trends. Otherwise,
winds will be southerly to southwesterly around 10-12 kts with a
few gusts of 18-22 kts this afternoon, before slowing a bit this
evening. Also expect some low level wind shear at OMA and LNK
this evening, with 40 kt southwesterly to westerly winds at
around 1500 ft agl.
