SHORT TERM /THROUGH TONIGHT/

Issued at 153 AM MST Sat Nov 22 2025

Shortwave ridging will bring dry and warmer weather to southern Colorado today as the next Pacific low pressure system pushes onshore across the northern Baja Peninsula. Areas of morning fog and low clouds across the San Luis Valley and portions of the southeast plains will be locally dense at times early, before gradually diminishing by mid morning. High temperatures today will rebound into the mid 50s to lower 60s across the plains, mid 40s to mid 50s for the valleys and 30s and 40s for the higher mountains. Winds will remain relatively light, increasing from the southeast in the afternoon as pressures fall to the west with the approaching system.

Upper low lifts northeastward into central AZ by 12z Sun. Broad difluence and increasing moisture spreads into the southern mountains overnight with snow expanding across the eastern San Juan mountains by dawn. A quick inch or two of snow will be possible across the southwest facing slopes after 09z as favorable southwesterly orographics works in tandem with approaching QG lift. Travel conditions will begin to deteriorate over Wolf Creek Pass towards morning where a winter weather highlight will go into effect at 09z. Elsewhere, mid and high clouds will invade from the south towards morning keeping low temperatures above normal. Kept lows in line with model blends. -KT

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 153 AM MST Sat Nov 22 2025

Pacific storm system will be moving across the region at the beginning of this time period (Sun 12 UTC). Mountain/Vally snow and rain over lower elevations will likely be ongoing across a good part of the region with only the far northern and eastern sections being dry early in the day Sunday. As the morning progresses, precipitation will lift north and east across the region. By Sunday evening, mid level low will likely be over the greater Pikes Peak region, and the precip will pivot from the northern sangres/across Pikes Peak region and then into northeast CO. By the early morning hours Monday the brunt of the precip will be out of our region, and moving across NE CO.

Overall, this system is rather potent, but somewhat moisture starved and is moving relatively quickly. Likewise, precip amounts will not be all that great, but there will be enough to warrant winter weather highlights for the San Juans where 5 to 10" is likely. The San Luis Valley and the remainder of the mountains will likely see snow with this system, but amounts will be less.

Two areas of concern I have attm will be how much snow will fall over 1.) the San Luis Valley and 2.) Northern EL Paso county. For now I have in the weather grids that snow will fall, and I do have some light accumulations for these two regions, but I am concerned the snow amounts may not be enough for these two areas. Additionally, we may need to add other mountain areas into the snow advisory later today.

The next concern will be the colder air that will move into the region starting Tuesday. The nice mild temperatures of Monday (60s plains) will be replaced by wind-blown 30s and 40s (plains) for Tuesday and Wednesday. Although it will be much cooler these two days it will be dry (except for some snow showers in the c mtns).

From Thanksgiving into Saturday it will be dry and seasonable.

Looking on from Sunday into the following weeks looks quite stormy over the intermountain region, including Colorado. \/Hodanish

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/

Issued at 1026 PM MST Fri Nov 21 2025

LIFR cigs have developed over KCOS and near KPUB due to light southeast upslope winds. IFR to LIFR vis in fog will be possible at both terminals overnight with clouds receding eastward from the mountains as north to northwesterly drainage winds set up between 12z and 15z Sat. KALS will also see IFR to LIFR cigs/vis develop overnight and persist through 15-16z. VFR conditions return for all three TAF sites on Saturday with light south to southeast winds increasing in the afternoon at 10-15 kts. High clouds will invade from the south Saturday evening. -KT
