Besides some passing high clouds over parts of the area, skies were clear over the region. Temps were noticeably cooler over the region as all of the plains were in the 20s with a few tens over the far eastern plains early this morning. A few 30s and 40s were noted immediately east of some of the mtns. The San Luis Valley was relatively warm with 30s and a 40 or two on the west side of the valley floor.

Today...

Overall, a relatively mild day is expected today over the region. warmest air will be over the higher elevations of the Raton Mesa region where upper 60s are expected over the Trinidad region while 50s and 60s will are expected over the rest of the plains. Larger valleys will be in the mid 40s to mid 50s; mtns 30s. It will be dry. Winds will be relatively light. Passing high clouds likely.

Westerly low level flow will pick up across the region as a lee trough develops over the plains. temps will be noticeably warmer across the plains tonight with 40s over the mtns/plains banana belt region and over the Raton Mesa region, 30s will occur over the lower Ark Rvr valley from Pueblo east to the KS border.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 159 AM MST Sun Dec 21 2025

Monday...

Main concern this day is some elevated fire weather concerns. It is going to be warm and record high temperatures will be possibe. Breezy surface west winds are anticipated and gap flow areas will likely see the strongest west winds of 20 to 30 mph. RH values will fall to around critical values (15%). Over the plains, expected max temps to range from the upper 60s over El Paso county to around 80 over Baca county. San Luis valley will be in the 50s. These temps will be at or close to record values.

Tuesday...

we will cool of a bit but will still be well above normal. 60s to around 70 are expected over the plains with around 50 in the valley. Winds will be more diurnal this day and RH values will be higher so no fire wx issues expected.

Christmas Eve and Christmas....

Plains: Dry and warm. Mid 60s to mid 70s. Some very spotty elevated weather concerns will be possible these two days.

In the mountains, especially along the divide, we will see increasing moisture, and expect to see snow over the mountains with some valley rain showers during daylight hours in the valley floor regions. Perusing the DESI data for the Wolf Creek area shows snow should start to pick up during the early morning hours of Christmas eve and continue through Christmas day. It appears steady, mainly light snow will fall over the Divide during this period. There will likely be some travel impacts but they should not be all that concerning as winds look relatively light and snow intensity does not appear to be all that high.

San Luis valley could see some showers, with M50s for max temps.

Friday into the weekend...

Periods of snow are expected to continue over the Divide. Main change during this period is the plains should start to trend towards cooler temps (50s). However it appears the lower elevations will continue to remain dry.

Overall, DESI is showing 2-3" of liquid water equivalent over the SW mtns from Wednesday into early next week, and this should lead to a couple feet of snow over this region. Other areas of the divide are showing 0.5 to 1 inch LWE. \/Hodanish
