KEY MESSAGES

- More wind driven snow for the central mtns late Friday into Saturday.

- Gradual warming trend (and mainly dry except central mtns) in the extended

SHORT TERM /THROUGH FRIDAY/

Issued at 224 PM MST Thu Dec 4 2025

Temperatures have been slow to recover due to light winds over the snow covered areas. Current temperatures are still hovering in the mid to upper 20s along the Arkansas River through Pueblo and in the San Luis Valley while in the 30s to low 40s elsewhere. With clear skies over the region tonight, it will be cold over the snow covered areas due to efficient radiational cooling for the first half of the night, and have leaned towards the colder side of the model blend solutions. Areas of fog will be likely across the San Luis Valley where strong inversions will develop. It is a little more amorphous as far as fog formation for Pueblo and Colorado Springs as north to northwesterly drainage winds increase (especially just off the surface) towards morning under strengthening northwest flow aloft ahead of the next system. Some patchy ground fog could develop early then erode as winds aloft increase. Have kept fog in the grids across the San Luis Valley and the lower Arkansas River valley for now.

Otherwise, temperatures will rebound a few degrees tomorrow, especially near the mountains were westerly winds will increase. High clouds could wreak havoc on the warm up where winds remain light and mixing more limited over the snow covered areas farther from the mountains. Overall a mix of 30s and mid 40s for the plains with 20s and 30s for the mountains and valleys. Snow starts to spread into the central mountains during the afternoon as the next system approaches from the northwest. -KT

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/

Issued at 215 AM MST Thu Dec 4 2025

A couple of disturbances will move southeast in the northwest flow pattern aloft, and this will bring additional snow to the central mtns during the Friday/Saturday time frame. Best chance of wind driven snow will be overnite Friday into Saturday. The winter storm watch has been upgraded to a winter storm warning for the central mountains with the Leadville area included in a Winter Weather Advisory for this time period. Most of the heavier snow will occur north of Cottonwood Pass though there will still be the potential for significant impacts to travel due to blowing snow over Monarch Pass as well.

Thereafter, northwest flow will continue aloft, but heights will gradually rise and the gradient will slacken. This will allow for a gradual warming trend over the entire fcst area with mainly dry weather. The only exception will be for some passing snow showers over the central mtns. \/Hodanish

AVIATION /18Z TAFS THROUGH 18Z FRIDAY/

Issued at 1040 AM MST Thu Dec 4 2025

VFR conditions expected through the day with a good chance of fog returning over the snowpacked San Luis Valley bringing IFR conditions to KALS. Odds are quite a bit lower for KCOS and KPUB as northwest winds aloft increase and drainage winds help keep any dense fog at bay. Have maintained an MVFR vis for now in a tempo group for both terminals, but this may be more confined to the Arkansas River valley before winds increase from the west Friday morning. -KT
