.DISCUSSION...
Issued at 321 AM CST Sun Dec 7 2025

Broad troughing remains in place across the CONUS, with a low-
amplitude shortwave over the lower Midwest. Surface
observations show low pressure now over Missouri moving quickly
east. Northerly winds have picked up behind the cold front,
strengthening CAA across the region. Coupled with extensive low
stratus, today will be much colder than the past couple days.
Afternoon highs will struggle to reach freezing in most spots.
Can`t completely rule out an afternoon flurry over north-central
KS with a weak vort-max passing through, but almost all short-
term guidance shows things staying completely dry.

Still looking at a nice warmup for the first couple days of the work
week, as shortwave ridging briefly builds in aloft. Sunshine and a
return of southerly flow will help highs rebound into the 40s for
Monday, while a surge of warm westerly low-level flow will boost
highs into the 50s for Tuesday. For most this will be our first day
in the 50s in two weeks.

The warmth will not last though, as a train of stronger Alberta
Clipper-type systems dropping out of western Canada help to deepen
the eastern CONUS trough. There still remains a good deal of
variability in how the overall pattern evolves, but overall some
things are coming into better agreement. The first system looks to
deliver a shot of cooler air for Wednesday, but the core of the cold
stays far enough northeast that we don`t drop too much below
average. Thursday looks to have a sharp baroclinic zone nearby, so
temperatures could be in the 50s, or potentially in the 30s. By
Friday though, there is better agreement in stronger high pressure
dropping south out of Canada, bringing a much colder airmass to the
area. So increasing confidence in another cold shot with highs
around or below freezing for the end of the week. The overall
pattern remains unfavorable for much in the way of precipitation,
with the predominant clipper track staying to our north. However
still can`t rule out a few opportunities for brief/light
precipitation (mainly in the form of snow) with any weak wave that
takes a more southerly track.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1124 PM CST Sat Dec 6 2025

Low pressure center is moving almost directly across the
area, so winds will continue to quickly switch to the northwest over
the next few hours, with some gusts to around 20 kts behind the
frontal passage. While MVFR ceilings at KTOP/KFOE have recently
cleared, more MVFR to at times IFR ceilings are approaching
from the north behind the front. These will arrive at the main
TAF sites in another couple hours. Expecting borderline MVFR/IFR
ceilings to persist for much of the period, though may begin to
scatter out by Sunday evening.
