  forecast totals continue to decrease as the system approaches.

.SHORT TERM /THROUGH SATURDAY/...
Issued at 226 PM MST Fri Nov 28 2025

As an upper-level trough continues to move through our region
Tonight and Saturday, get ready for a blast of much colder weather.
As the system moves in from the northwest, snow showers will spread
over portions of the Central Mountains, dropping a few inches at the
higher peaks and lesser amounts over the slopes. Meanwhile, as the
front moves across the plains tonight, gusty winds and cooler temps
will set in, with overnight lows dropping into the teens-20s. Areas
east of the mountains are still expected to remain dry, as there is
not a lot of moisture with this passing system, though a few flakes
may hit the top of the Palmer Divide very early Saturday morning.

Snow will start dissipating by mid-morning on Saturday, due to how
quickly the system will pass through the region. Behind the front,
high temperatures for Saturday will be a stark contrast to today,
with low-mid 30s over the eastern plains and 30s-40s over the high
valleys. Cloud cover will also start to decrease moving into the
afternoon hours, with breezy north winds remaining over the far
eastern plains.

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 303 AM MST Fri Nov 28 2025

Saturday Night Through Monday.

Our coldest night of the season so far is expected for Saturday
night, with single digits likely over our far eastern plains, and
low teens expected elsewhere on the plains and for mountain valleys.
Our temperatures stay even colder on Sunday for our second day of
post-frontal air, as another reinforcing push of arctic air arrives
with a secondary trough pushing through later on Sunday. Daytime
highs look to stay in the 20s and 30 on Sunday, and this Arctic push
looks to bring slight better snow chances along with it, however,
the system is still moisture starved and very quick moving. Snow
looks to begin over the central mountains on Sunday afternoon,
spreading across the high country through Sunday evening. All of our
mountain ranges have decent chances at picking up 1-2 inches of or
so of new snow, and our plains even have a solid chances at a
dusting, especially near the mountains, but the system will be out
of here quickly and the snow will be lower in water content given
the source region. Meaningful moisture is not expected on the
plains, though our first wake up with fresh snowfall on the ground
will certainly be possible for Monday morning, especially near the
mountains, and for the Palmer and the Raton. Highest totals with the
Sunday night event look to be once again over the western and
northern slopes of the central mountains, where 3 to 5 inches will be
possible, and also over the San Juans, where similar amounts are
forecast. Though the snow is exciting, the temperatures will be
noticeable and potentially more impactful to most. Highs look to
remain in the 30s once again on Monday, with overnight lows dipping
back down in to the teens and single digits again on Monday night.

Tuesday Onwards..

Models push the arctic air out by Tuesday, warming most areas
back up into the 40s, and back into near normal ranges by
Wednesday. Our pattern looks to remain unsettled through next
week though, and current trends point towards more chances for
snow, especially for the high country, by mid-week.
