.DISCUSSION...
Issued at 248 PM CST Tue Dec 23 2025

Tonight through Thursday (Christmas Day):

Latest surface analysis reveals a front stalled from south-
central KS into central MO with a warmer and considerably more
moist air mass residing to the south of that feature. That
moisture is contributing to widespread low clouds and areas of
fog as of early afternoon. The boundary is forecast to weaken
while lifting north with low clouds and areas of fog developing
into our area late tonight into Christmas Eve morning. Some
drizzle is also possible, especially along and south of I-80.
The good news is that temperatures are expected to remain above
freezing, so we don`t anticipate any ice accumulation.

The low clouds and fog are likely to linger through the
morning, impacting afternoon temperatures, particularly in far
eastern NE and western IA where highs in the upper 40s to low
50s are forecast. We could see more sunshine elsewhere,
allowing temperatures to warm into the mid to upper 50s. The
record high temperature of 58 at Norfolk could be within reach.

A weak front is forecast to slowly settle south through the
area Christmas Eve night before stalling across northern KS and
northwest MO Christmas Day. Light winds in the vicinity of the
front will favor the development of widespread fog and low-
clouds, which will linger into Christmas Day. Some drizzle
appears possible, but again, the best potential will exist at
locations that remain above freezing.

Reduced visibilities due to the fog could impact travel this
holiday period, as could slick spots developing on untreated
bridges.


Friday and Saturday:

The primary feature of interest this period is a short-wave
trough, which is forecast to amplify over the north-central
U.S. Saturday into Saturday night. At the surface, a strong cold
front will sweep through the region late Saturday afternoon and
evening. Temperatures are expected to warm slightly ahead of the
front with highs in the 50s and 60s both days. This forecast
update will indicate high temperatures at or within a degree of
the records at Lincoln (64/26th and 62/27th).


Sunday and Monday:

A considerably cooler air mass will filter into the region
behind the front with highs in the 20s and 30s forecast both
days. Measurable precipitation chances appear minimal through
the duration of forecast period.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1126 AM CST Tue Dec 23 2025

Late morning satellite and observational data show widespread
low clouds and fog across portions of eastern KS and western MO,
where a warm and moist air mass currently resides. That air is
forecast to advance north into eastern NE and western IA
tonight into Wednesday morning with low clouds and areas of fog
developing. The 12z HREF indicates a greater than 80% chance of
IFR ceilings developing at KLNK and KOMA in the 24/12z-24/13z
time frame, and as such, IFR conditions have been introduced to
the forecast at those locations. Some drizzle appears possible,
though temperatures should be warm enough such that no ice
accumulation is expected. Current indications are that the fog
and/or low clouds will remain to the south/east of KOFK, so
prevailing VFR conditions will be maintained there.

Light northeast winds this afternoon will become southeast tonight
into Wednesday morning.
