.DISCUSSION...
Issued at 301 AM CST Wed Dec 24 2025

A dreary start to Christmas Eve is developing. A broad and weak warm
front is beginning to slowly lift north this morning. This is
ushering in low clouds and fog. This fog has been dense over
northern Kansas and is expected to lift into southeast and east-
central Nebraska through the morning hours. A Dense Fog Advisory has
been issued as a result of this. Fog may develop elsewhere across
the region, but this may be patchier and less dense. Additionally,
light drizzle may develop over southwest Iowa as well. The fog and
low clouds will likely slow daytime heating across the area. That
being said, widespread upper 40s and lowers 50s are likely, with
temperatures closer to 60 further west where sunshine may break out
this afternoon.

The weather for Christmas day appears very similar to Christmas Eve.
The aforementioned warm front will remain in the vicinity heading
into this evening. Widespread fog and low clouds redevelops and
expands tonight into Christmas morning. This will likely slow
nocturnal cooling keeping most locations in the upper 30s. Dense fog
may once again be possible across portions of the area through the
morning hours. With more widespread fog and clouds expected,
temperatures may come in couple degrees cooler than Christmas Eve.

Despite a weak disturbance on Friday, temperatures continue to be
well above normal and the same is likely for Saturday as well.
Though that will finally come to an end late in the day on Saturday
as a much stronger front swings through the area. The stronger front
is aided by more significant troughing over the Great Lakes region.
Temperatures are sent tumbling back into the 20s and 30s during the
afternoon with single digits to teens each morning to start next
week.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1102 PM CST Tue Dec 23 2025

Light easterly winds will gradually turn to the south overnight,
as a moist air mass drifts north from Kansas. Models continue to
indicate the potential for fog to overspread parts of central
and eastern Nebraska, potentially reaching into western Iowa by
early Wednesday morning. Currently, the best chance for MVFR to
IFR visibilities will be at KLNK from 12-17Z. KOFK and KOMA look
to be on the fringes of the foggy conditions, but could dip to
MVFR from 13-17Z. MVFR to IFR cloud cover will also infiltrate
the region early Wednesday morning, potentially bringing patchy
drizzle. The best chance for -dz remains across far southeast
NE and southwest IA, so will not include a mention in the TAF at
this time. Temperatures should remain a few degrees above
freezing overnight, precluding any icy conditions.
