KEY MESSAGES

- Snow ends Monday with continued cold, warming on Tuesday.

- The next upper storm system will move across the area Wednesday with another round of snow for the Mountains, down into the I-25 corridor.

SHORT TERM /THROUGH MONDAY/

Issued at 227 PM MST Sun Nov 30 2025

Temperatures will remain cool the rest of today, with increasing cloud cover as an upper trough continues moving through our area from the northwest. Light snow has already started over portions of the higher terrain, mainly over the Central Mountains.

This evening into tonight, snow showers will spread across the rest of the higher terrain, mountain valleys, and potentially portions of the Pikes Peak Region as well. The main forecast challenge for this event will be tonight. With the system moving across the I-25 corridor and providing some instability aloft, some of the high-res model guidance is showing the potential or a few brief snow bands over El Paso and/or Pueblo Counties, typically prior to 11pm or so. Given the fast-moving nature of this system, should these snowbands form they would result in about an hour of moderate snowfall rates, but those rates could bring forecasted trace amounts of snow towards the 1-2 inch range. So nothing worthy of any winter highlights, but still more than enough to briefly limit visibility and make roadways slick for a few hours.

Current high-res models predict an increase in confidence in the formation of a few embedded bands of heavier snow, but the placement will still be dependent on the timing of the upper-level ascent and localized terrain factors. Current guidance is split between northern Pueblo County and central El Paso County,including portions of Colorado Springs. People within these areas should be wary of quickly changing road conditions this evening.

Latest snow totals have not changed much from the previous forecast. Heaviest accumulations are still expected over the San Juans and the peaks of the Southern Sangres, with an additional 7-10 inches between this evening and Monday morning. Meanwhile, the rest of the Central Mountains and Pikes Peak will see widespread 2-4 inches, with a few spots getting 5-6 inches. The mountain valleys, Upper Arkansas, and areas along and west of I-25 should see less than an inch or so. However, once again, embedded snow bands in El Paso and/or Pueblo Counties may form briefly this evening, and could bring localized amounts closer to an inch or so. Anywhere east of I- 25 should only receive trace amounts of snow, if any precipitation manages to make it out that far before the system moves out of our area.

Once the system moves past early Monday morning, conditions across the area will dry out, with high temperatures climbing into the high- 30s to low-40s over the lower elevations, while the mountains remain in the teens-20s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 226 AM MST Sun Nov 30 2025

Models are in much better agreement tonight through the extended period, with less spread in the track of the Wednesday system. Ensembles are also more in line with the 00z cycle.

Monday night through Tuesday...a brief break in the active weather is forecast during this time period, before the next upper system moves into the region. Flow aloft transitions westerly, and enhanced mixing will allow for temperatures to warm quickly through the 40s to lower 50s for much of the Plains. Gap wind prone areas along the I-25 corridor could see breezy conditions through the afternoon. A few light snow showers may be possible over the Central Mountains late in the day and into Tuesday night.

Wednesday...the next quick moving upper trough will transition across the state on Wednesday. Models in much better agreement this morning, with all solutions dropping an upper trough into the Intermountain West, and across Colorado. Snow will increase late Tuesday night across the higher terrain, and spread eastward Wednesday morning into the afternoon. A cold front will arrive on the Plains Wednesday morning, with northeasterly low level flow developing behind it. This will usher in colder air with a quick period of snow Wednesday afternoon into the evening as the upper trough axis swings through. The heaviest snow looks to be confined ot the higher terrain, with a couple inches possible down into the I-25 corridor. Much will depend on temperatures, with lower to mid 30s expected Wednesday afternoon.

Thursday through Sunday...models in agreement that persistent northwest flow with embedded waves will prevail for late in the work week through next weekend. Near continuous light snow would prevail across the Central Mountains due to favorable orographic flow. As for the Plains, northwest flow usually limits precipitation and dry conditions are likely. Temperatures will be dependent on individual cold fronts that may impact the area, and with cold air settled to the east, it wouldn't take much to bring some of that cold air back into Colorado. For now, high temperatures look to move from the 30s on Thursday, back into the 40s to possible near 50 Friday into the weekend. Mozley

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1043 AM MST Sun Nov 30 2025

KALS: Gusty west winds and increasing clouds will move in this afternoon, lowering cigs to MVFR through tonight and into early Monday. Snow showers will move off of the higher terrain, starting around 02Z, with potential impacts to the terminal between 05-09Z in the form of lower clouds and light snow with limited visibility. VFR conditions will return later Monday morning, near the end of this forecast period.

KCOS and KPUB: MVFR conditions will mostly persist through the next 24 hours, due to increasing cloud cover. Later this evening, by about 03Z or so, an incoming system will spread snow across the higher terrain to the west. While VCSH will be present at both terminals, there is also a low-end chance for isolated bands of snow to move out over the I-25 corridor. If snowfall does move to the terminals, it will result in brief periods of lowered visibility and snow showers. Have included PROB30 groups to account for this possibility. Outside of that, lingering nearby showers and some lower clouds will last into early Monday morning, before VFR conditions are expected to return.
