.SHORT TERM /THROUGH TUESDAY/...
Issued at 203 PM MST Mon Dec 22 2025

Currently...quiet and warm conditions will prevail through this
afternoon across southern Colorado. A few mid and high clouds
continue to spread overhead, and temperatures are mostly in the
upper 60s to mid 70s, with a few 80s near Springfield. Spotty,
Red Flag conditions due to low humidity and gusty winds, mainly
along the I-25 corridor.

Tonight and Tuesday...upper level high pressure will continue to
build northward and shift east into the Central Plains overnight
and through the day tomorrow. Flow will shift more southwesterly
on Tuesday, with increasing mid and high cloud cover late
tonight into tomorrow morning. Overnight lows will fall into the
30s and 40s across the Plains, with coolest lows along the lower
Arkansas River Valley. The San Luis Valley will see upper teens
to lower 20s. Temperatures look to be slightly cooler on
Tuesday, with upper 60s to mid 70s across the Plains. These
highs are 15 to 25 degrees above normal for this time of year.
Colorado Springs and Pueblo will likely fall a few degrees
short of Dec 23 records (both 77 degrees), but Alamosa will be
within a degree or two (58 is the record, and the forecast high
is 57). Overall, no precipitation is expected through tomorrow
afternoon. Mozley

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
Issued at 209 AM MST Mon Dec 22 2025

Not much change in the extended. Trough still forecast to develop
over the Western CONUS and this will bring increasing moisture to
the CONTDVD region staring XMAS eve and lasting into the weekend.
Perusing the DESI guidance, 2-3" of liquid equivalent is expected
over the San Juans. At this time, the heaviest snow will fall late
XMAS eve through Christmas day. The snow could be heavy during this
period. for the remainder of the period it appears on and off light
snow will continue into early next week. For the rest of the CONTDVD
region, accum will be less with generally 0.5 to 1.0" of liquid
equivalent falling over the region.

Most of the precip in the extended period is destined to remain over
the CONTDVD region with only a some showers reaching the mtns
adjacent to the plains. Accums look to in in consequential at this
time.

As for temps, it is NOT going to feel like Christmas around the
region (especially plains and larger valleys) as very warm temps
will last into late week. 60s and 70s are near certain every day
through Friday. There could be some spotty elevated weather
conditions over the lower elevations during this period. By this
weekend into early next week, temps should start to cool off across
the plains.

Taking a peak beyond day 7, there appears to be some hope for cooler
weather with some precip over the lower elevations as the longer
range guidance (CPC, DESI, deterministic solutions) is showing
troughing moving over the intermountain west the mid week period of
next week (AOA New Years time period). /Hodanish
