.SHORT TERM /THROUGH WEDNESDAY/...
Issued at 207 PM MST Tue Dec 23 2025

Currently...most of southern Colorado has warmed up nicely this
afternoon, with 60s and lower 70s across the Plains. The
exception is a pocket from Colorado Springs, down to Pueblo,
which have temperatures in the 50s. Overall, temperatures may
warm a couple of more degrees this afternoon, before cooling
around sunset. A few areas along the southern I-25 corridor are
seeing occasional wind gusts near 30 mph, which has helped
boost temperatures there. Widespread mid and high level clouds
continue to stream across the region as flow aloft increases
from the southwest.

Tonight and Wednesday...the upper level ridge sitting over the
Central Plains will slowly drift eastward into the Missouri
Valley over the next 24 hours, while the trough off the west
coast slowly moves east. This will lead to increased
southwesterly flow across southern Colorado through Wednesday.
Expect a quiet night tonight, with mild temperatures over
southern Colorado. Most of the Plains will see 30s to 40s by
morning, with the coldest readings along the lower Arkansas
River Valley. Lower 20s are expected across the San Luis Valley.

Moisture in the southwesterly flow will begin to push out of
the Great Basin and into western Colorado throughout the day
tomorrow. This increased moisture will lead to afternoon snow
showers along the Continental Divide, mainly over the San Juans.
A minor dusting of snow could be possible across the higher
peaks by sunset. Elsewhere, dry conditions are forecast to
prevail, with high temperatures once again well into the 60s to
lower 70s on the Plains. (Records: 70 in Colorado Springs with a
forecast of 67, 76 in Pueblo with a forecast of 71, and 58 in
Alamosa with a forecast of 59) A few areas down near Springfield
could push 80 for tomorrow. Mozley

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
Issued at 215 AM MST Tue Dec 23 2025

Longwave Pacific trough to linger across the western US through
Friday, then weakens, splits in two and tracks east across the Great
Basin and Rocky Mt region Saturday through Monday.

Wednesday night through Friday...Models are in fairly good
agreement showing a longwave Pacific trough producing persistent
southwest flow across the desert SW through Friday. This will
keep moisture advection in place for the Four Corners and
western CO through the week, bringing some snow to the higher
terrain while at the same time keeping the eastern plains dry
and significantly warmer than normal. Snow will be ongoing
Wednesday night, and remain off and on into the weekend, with a
focus on the Continental Divide, and the southwest mts seeing
the most snow. Total snow amounts Wed through Fri are forecast
to be in the 4-10 inch range, with the eastern San Juan Mts
again having the best chance at seeing the higher amounts. The
heaviest snowfall rates will likely occur late Wed night through
Christmas. Latest QPF amounts have come down a bit, though
total QPF across the southwest mts through Fri are still nearing
1 inch.

As for temps, Thu will be the warm with highs in the 50s for
the high valleys, and upper 60s to upper 70s for the plains. Fri
will be slightly cooler but still well above seasonal normals,
with highs in the mid 40s to around 50F for the high valleys,
and upper 50s to around 70F for the plains.

Saturday through Monday...There are some differences in model
solutions this weekend, but in general the upper trough finally
starts to move east on Sat, weakening as it splits into two pieces.
Light snow will remain a possibility for the Continental Divide Sat
and Sun. Meanwhile, the upper system pushes east across the Rockies
and forces a surface cold front south into CO by late Sat night.
While Sat looks to be a cooler day, the more significant drop in
temperatures is forecast for Sun and Mon when afternoon highs may
actually be near seasonal normals. There is an isolated shot of some
light showers Sat night with frontal passage, but the safe bet is
continued dry conditions for the plains through the extended. Plan
on highs Sat in the 40s for the high valleys, and 50s to near 60F
for the plains. For Sun and Mon, widespread high temps in the 40s
are expected. Moore
