Currently...

Patchy fog was noted along the Arkansas rived from Pueblo east to
the KS border, with it being most widespread along the Arkansas
river in Bent and Prowers counties. Additionally, patchy fog was
noted in the San Luis Valley. A band of wave clouds was developing
along the mtns/plains interface.

Temperature-wise this morning, things were quite interesting, An
area of single digits was noted from the east side of Pueblo
out east into Bent and western Kiowa county. over the rest of
the plains it was mainly in the 20s, with some low 30s in
eastern Fremont county and far western Pueblo county.
Temperatures in Pueblo West were noted to be in the L30s while
here at the airport single digits were occurring. Elsewhere, it
was cold in the mtns with mainly single digits most places in
the valleys and mtns.

Today...

On the plains, where the snow pack remains it will be cooler than
the rest of the plains. Expect max temps in the 30s in snow packed
areas while the remainder of the plains will be in the 40s.
warmest temps will be over the far southeast sections of the
southeast Colorado plains. Mtns and valleys will remain cool
with max temps in the 20s to around 30 valleys and 10s and 20s
mtns.

A weak disturbance will move into the central mtns this afternoon,
and this will bring increasing chances of snow showers to this
region as the afternoon progresses.

Tonight...

Snow over the central mtns will let up early this evening, but will
once again ramp up significantly later tonight as a much stronger
disturbance moves into the central mtns. A Winter Storm Warning goes
into affect around midnight tonight and will continue into Saturday
night. Winds will be on the increase tonight over the higher
terrain.

Over the plains, lee troughing will develop and this will allow for
a bit warmer temperatures tonight over the plains, especially along
the mtns/plains interface where min temps will likely be in the 20s.
10s are expected over the lower Ark rvr valley while the Raton Mesa
will be in the 20s. Valleys will likely see temps in the single
digits, with 10s and 20s mtns.

Issued at 212 AM MST Fri Dec 5 2025

Saturday....Snow and wind will continue along the Contdvd area with
some of the snow pushing into the wester sections of the pikes Peak
region and Northern Sangres and possibly the northern San Luis
Valley region. Most of the accumulating snow will remain d in the
central mtns, with the heaviest accums occurring in the central mtns
in Lake County. Over the remainder of the fcst area it will remain
dry. With downslope flow over a good part of the region, temps will
warm up Saturday, with highs in the 40s and 50s plains, 30s
SLV. It will be windy in most of the mtns and breezy elsewhere.

Sunday...

Snow will end early Sunday morning in the central mtns. A
Pacific front will move across the region early in the morning,
and max temps will be several degrees cooler region-wide on
Sunday as compared to Saturday. Winds will be less on Sunday,
but still a bit breezy in spots.

For the remainder of the fcst, northwest flow will continue through
the rest of the period. A few weak disturbances will move down
across the region in this flow, but there impacts will be minor,
with mainly some snow showers in the central mtns at times. Overall
there should be a slow gradual warming trend next week, with a few
weak fronts moving across. Temps by late week may be touching 60 in
places on the plains with 50s elsewhere. /Hodanish

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1043 AM MST Fri Dec 5 2025

VFR conditions with high cloudiness will overspread the region
through Saturday at the terminals. KALS will see another round
of fog tonight with IFR to even LIFR conditions possible around
sunrise. Northwest to westerly drainage winds at KCOS and KPUB
should prevent fog formation but could cause some low level wind
shear towards dawn. Confidence is low that this will occur
within 2000 feet, so have not introduced low level wind shear
into the TAFs just yet, but this will be monitored and may
become necessary with the 00z TAF issuance. -KT
