.DISCUSSION...

Christmas

Widespread, dense fog blankets much of the Upper Midwest this
morning. This fog is brought on by weak isentropic ascent over a
broad frontal zone over the region. Fog continues into Christmas
morning and perhaps even into the early afternoon. It will be dreary
while opening presents later this morning. One positive, is the fog
is keeping overnight temperatures a little milder in the upper 30s
and 40s for all but Northeast Nebraska. One negative, is the same
fog and clouds limits afternoon heating, keeping everyone in the 40s
to near 50. That said, temperatures remain warmer than normal.

Friday and Saturday

Fog is expected to redevelop later tonight into Friday morning,
especially over the Missouri Valley and western Iowa. This is due to
the frontal zone making little progress over the next 24 to 36
hours. By Friday afternoon, a weak "cold" front actually results in
warming temperatures. This is due to warm west winds and clearing
skies. Temperatures once again climb well into the 50s and 60s
during the afternoon, approaching records for some. Saturday starts
much the same as on Friday, but change will be on the doorstep.

Sunday and Next Week

By late Saturday into Sunday, a two part weather system will begin
to impinge on the region. One system will swing east from the
Pacific Northwest, while another lifts out of SoCal. These features
cause a low pressure system to quickly lift northeast through the
Central Great Plains. A strong cold front will initially signal this
low pressure systems impact with rapidly falling temperatures early
Sunday morning. Widespread 20s and 30s make their return to the
region and little if any daytime heating is expected. At the same
time, the developing precipitation shield may bring light snow to
the area. At this time, the chance remains low (10-20%), but this
may be something to monitor. The real cold arrives Sunday night into
Monday morning as single digits and teens are forecast. Thus, a
chilly start the next week. The colder weather continues into next
week, but will slowly begin to warm back up as weak ridging returns
to the region.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 511 AM CST Thu Dec 25 2025

Widespread fog continues across the region with pockets of dense
fog as well. Visibility is expected to continue to be LIFR or
IFR over the next several hours. Ceilings will also remain LIFR
and IFR through the morning hours. Slow improvement to
visibility and ceiling is expected later this afternoon.
Visibility is forecast to improve to MVFR and eventually VFR by
mid-afternoon. Ceilings may also lift to high-end IFR to low-end
MVFR. Heading into this evening, worsening ceilings and
visibility is expected. Confidence is highest in both the return
of MVFR and potentially IFR visibility and IFR ceilings at OMA
this evening. OFK and LNK may be on the western edge of the fog
and ceilings. There is low confidence in fog development across
these terminals and ceilings may also fluctuate between MVFR
and IFR. If everything stays east, these terminals will end up
VFR. Trends will be monitored in the coming TAFs. Otherwise,
light east to southeast winds are expected across the region.
