KEY MESSAGES

- Dry with a gradual warm up through mid week as we melt off the snow cover across the lower elevations.

- A cold snap possible late week into next weekend, though details on the western extent of cold air spreading southward through the plains is still in question.

SHORT TERM /THROUGH TONIGHT/

Issued at 207 AM MST Sun Jan 11 2026

Dry weather with light winds expected for the short term with the primary forecast challenge revolving around temperatures. Current readings range from the single digits and teens across most of the lower elevations with negative single digits across the center of the San Luis Valley over the snowpack. Temperatures will rebound some more today, though with light winds, most of the solar radiation will go into snow melt where the snow cover exists. Have leaned the forecast towards the 10th percentile of the National Blend of Models over the snow covered areas. This will result in 30s for the snow covered areas with upper 20s in the San Luis Valley. The remainder of the valleys and lower eastern slopes will see some readings rebound into the 40s with primarily 20s for the high country.

Another mostly clear night will allow temperatures to cool efficiently once again and went closer to guidance vs NBM in the San Luis Valley with temperatures dropping into the negative single digits. Elsewhere blended down towards the colder NBM range where lingering snowpack is likely to exist. Added some patchy fog into the grids for the San Luis Valley, but confidence is low and it will depend on if some snow melt can occur today. Overall it will be a quiet 24 hours with slowly moderating temperatures. -KT

LONG TERM /MONDAY THROUGH SATURDAY/

Issued at 207 AM MST Sun Jan 11 2026

The moderation in temperatures continues through early next week as we continue to chip away at the snowfield across the lower elevations. Nudged temperatures down a bit for Mon and Tue but let the forecast trend closer to NBM towards mid week as we gradually loose the snow cover. Upper high out west amplifies opening the door for energy to drop south out of Canada, sending a cold front through eastern CO. The first surge comes through Tue night, though it is not overly cold for eastern CO as the core of the colder airmass is progged to stay east. Another system digs down for Fri into Saturday with some variability in how far west the core of colder air will descend through the plains. The more amplified farther west GFS/GEFS solution suggests a much colder Fri and Sat with a chance of light snow for the southeast mountains and plains, while EC/EPS is farther east with the cold airmass and keeps southeast CO dry. Confidence is a strong cold snap is still low, though the 10th percentile of NBM shows high temperatures in the 20s across the plains by Sat with the coldest outlier solutions in the teens. Will need to monitor this closely as a cold snap of some magnitude does look likely given the consensus for deep north to northwesterly flow aloft. But how cold remains difficult to pin down at this point. Maintained the NBM blend for now. -KT

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

Issued at 207 AM MST Sun Jan 11 2026

VFR conditions expected over the next 24 hours with light diurnally driven winds. There is a low probability (less than 10 percent) for fog at KALS towards the end of the TAF valid period early Mon morning, especially if we can melt some snow today. KPUB has an even lower chance for some patchy ground fog Mon AM given deep dry air aloft and some mixing above the surface. Given such low probabilities have left fog out of the TAFs at this point, but this will be re-assessed with future issuances. -KT
