.SHORT TERM /THROUGH TONIGHT/...
Issued at 213 AM MST Thu Dec 25 2025

Currently...Brisk southwest flow aloft in place across the region,
with snow reported over the sw mts and satellite imagery showing
enhanced cloud cover over the higher terrain. Temps have cooled into
the 30s and 40s for most locations as of 1 AM, but a few of the more
wind-prone areas were still reporting temps in the 50s.

Today and tonight...Not a lot of change over the next 24 hrs,
providing for a very warm Christmas day for many, while the mts get
a taste of snow.

The upper Pacific trough remains centered just off the West Coast,
which in turn keeps strong southwest flow aloft locked in across the
Four Corners region. Moisture streaming into western CO will help
produce snow for the higher terrain, with a focus along the
Continental Divide. Snowfall should remain light, briefly moderate
at times, but the steady enhanced southwest winds will produce areas
of blowing and drifting snow, and reduced visibility, especially
across Wolf Creek Pass. Total snow amounts through Fri morning are
forecast to be in the 3 to 6 inch range for the eastern San Juans, 2
to 4 inches for the remainder of the Divide, and around 2 inches for
the peaks of the Sangres.

Latest model runs keep the upper jet moreso over the northwest quad
of CO and to the north, so the strongest wind gusts will likely not
be a problem for the forecast area. However, models do hint at some
high gusts across the mt peaks, especially for the southern Sangres,
so stronger wind gusts across La Veta Pass and in the normal high
wind/gap flow areas in the vicinity of Walsenburg are probable this
afternoon into the early evening.

The enhanced downslope winds will help boost temps today to record
or near record levels, with highs in the 50s to around 60F for the
high valleys, and upper 60s to upper 70s for the plains. As the
forecast max T stands right now, Alamosa will be near the record for
the day, while both Colorado Springs and Pueblo are forecast to
break the record for Christmas Day. Moore

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Issued at 213 AM MST Thu Dec 25 2025

Friday..

Our flow aloft becomes more and more southwesterly tomorrow as our
next trough begins to move onshore. This keeps snow showers going
over the San Juans, though totals look to remain on the lower end.
Daytime highs remain well above average, but are not expected to
break records again. Colorado Springs may tie theirs, since their
standing record for the 26th is rather low end at 64F, but that is
the only record in jeopardy of our climate sites at this time. Highs
in the 60s to low 70s are likely over the plains, with 50s for
mountain valleys. Winds will be lighter tomorrow as we transition
towards southwest flow, though southwesterly gusts to 35 mph or so
will be possible over the higher peaks of the Sangres, and 30 mph
gusts will be possible through our gap flow in Huerfano. This will
mean that very spotty elevated fire weather conditions will be
possible through the gap in Huerfano tomorrow. Elevated fire weather
conditions with brief gusts to 25 mph will be possible over Teller
County as well. Increasing cloudiness is expected throughout the day
tomorrow.

Friday Night Through Saturday..

Temperatures remain much warmer than normal Friday night, with lows
near freezing for much of the I-25 corridor and Lower Arkansas River
Valley. The San Luis Valley will be cooler with temperatures falling
into the 20s, and our southeast plains will be warmer with
temperatures only falling into the 40s. Snow tapers over the San
Juans through the overnight hours. Daytime highs on Saturday look to
be just a few degrees cooler than Friday, though still around 12 to
15 degrees warmer than normal for this time of year. Most of the
plains looks to warm into 60s, with a few low 70s possible on our
far southern plains, and 50s likely for the Pikes Peak region and
our mountain valleys. Models are still showing a messy split with
the incoming shortwave, bringing the trough axis into far western
Colorado late Saturday night. Though this progression has slowed, it
still favors a split, with a stronger northerly push and gusty winds
across the area on Saturday and Sunday. For Saturday though, we look
to be pre-frontal throughout the daylight hours, which may bring
chances for critical fire weather conditions across our southern
plains. Snow showers look to increase from west to east across the
high country throughout the daytime hours, spreading into the
Continental Divide by late Saturday afternoon, and into the Sangres
by Saturday evening.

Sunday..

Our much anticipated cold front finally pushes through Saturday
night into early Sunday morning, spreading rain and snow chances
across the plains as we head into Sunday. Models continue to push
this timing back, which is a trend that may continue happening for
the next few runs. At this time, QPF is very minimal for the lower
elevations, and snow amounts look to be generally less than an inch
along and west of I-25, with just a dusting further east, but these
outcomes could change as the event draws closer in time. Daytime
highs are trending cooler as models close in as well, with
temperatures in the mid to upper 30s for much of the plains and our
mountain valleys, with a few areas in the low 40s on our far
southeast plains. Breezy northerly winds will also be possible,
especially for our far eastern plains. We finally see some winter-
looking overnight lows Sunday night into Monday as well, with
temperatures falling into the low teens on the plains and single
digits over the San Luis Valley behind the front.

Monday Onwards..

Provided the front doesn`t slow down anymore, we are in cool and dry
northerly flow behind it by Monday, with near normal temperatures.
Highs look to climb into the 40s for much of the plains, with 30s
for the San Luis Valley. A warming trend looks to begin on Tuesday,
with dry conditions and weaker winds persisting through at least
Wednesday as a broad area of high pressure sits to our west and
leaves us in northwest flow. Models hint that this pattern may stay
in place through late next week before southwest flow and more
chances for precipitation return, at least for the high country.

.AVIATION /12Z TAFS THROUGH 012Z FRIDAY/...
Issued at 213 AM MST Thu Dec 25 2025

VFR conditions anticipated across the forecast area over the next 24
hours, including the three main TAF sites of KCOS, KPUB and KALS.
Steady strong southwest flow aloft will translate to gusty SW
surface winds at times at TAF sites between approx. 19z-02z though
KPUB will likely be delayed an hour or two. High level cloudiness
will be on the increase through the day.
