.SHORT TERM /THROUGH THURSDAY/...
Issued at 223 PM MST Wed Dec 31 2025

Tonight through Thursday...

Westerly flow aloft will increase this evening and into the
overnight. With a bit of energy and more moist air heading into the
Continental Divide, we can expect to see some snow spread into a few
of the ranges overnight into Thursday. That being said, forcing is
overall pretty weak, and there isn`t an abundance of available
moisture, so accumulations will be pretty light, with a few inches
or less expected by the end of Thursday over the Sawatch and
Mosquito Ranges, the La Garitas, San Juans, and maybe the northern
Sangres. Most places will only see a dusting to a half inch, with
the San Juans maybe seeing up to 4-5 inches. Meanwhile, increasing
cloud cover will keep overnight lows a bit warmer tonight, with
teens to low-20s for the valleys and 20s to around freezing for the
eastern plains.

We warm right up again on Thursday, with 50s for the valleys and
mostly 60s for the plains. Other than the light snow over the
mountains, the area will remain dry and mostly cloudy, with
relatively light winds.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Issued at 241 AM MST Wed Dec 31 2025

Thursday night through Friday...the first embedded upper wave will
track eastward overnight, with a brief lull in snowfall along the
Continental Divide, before a secondary wave strengthens
overhead. Overnight lows be mild heading into Friday morning,
with upper 30s to lower 40s along the Eastern Mountain lee
slopes, and upper 20s for the lower Arkansas River Valley.

The next embedded upper wave will track across Colorado on Friday.
Snow looks to increase in intensity during the morning hours, and
persist into the afternoon. That being said, snow rates look low,
with an additional inch or two possible through the day. This is a
quick moving wave, and will depart by late afternoon, with snow
ending by Friday evening. Storm total accumulations for both the
Thursday and Friday waves looks to be in the 2 to 5 inch range. Dry
conditions will continue across the Plains. Friday`s high
temperatures will remain warm, with upper 50s to lower 60s on the
Plains, and near 50 across the San Luis Valley.

Saturday and Sunday...upper ridging will pass across Colorado
Saturday into Sunday, with increasing southwesterly flow by Sunday
afternoon. Temperatures will slightly cool on Saturday, with upper
50s to near 60 on the Plains. Increasing southwesterly flow will
help boost temperatures on Sunday through the 60s to possibly
lower 70s on the Plains. There could be spotty fire weather
conditions in gap wind prone areas of Huerfano County due to low
humidity and gusty winds.

Monday through Wednesday...the upper ridge will sit across the
Central Plains, with southwesterly flow remaining in place across
Colorado. This will lead to periods of light snow for the
Continental Divide during this period. Nothing at this time looks to
heavy, with a few inches possible by mid week.
Temperatures look to cool across the region, with upper 50s to low
60s Monday, falling into the 50s for Tuesday and Wednesday.
No precipitation is in the forecast for the Plains. Mozley
