KEY MESSAGES

- Dry and breezy weather with above normal temperatures continue over the next 7 days, with light snow showers possibly returning to the central mountains Wednesday.

SHORT TERM /THROUGH FRIDAY/

Issued at 202 PM MST Thu Dec 11 2025

Currently...Windy and warm across much of the forecast area today as an upper disturbance helped kick off stronger wind gusts and an influx of dry air for the I-25 Corridor. A good amount of high level cloudiness persisted along and in the lee of the eastern mts, but stronger winds helped boost temps into the mid 60s to mid 70s for much of the plains, and to near 80F for the southeast corner. The high valleys have climbed into the upper 40s to mid 50s as of 1 PM. Red flag criteria was starting to be met along the entire southern I- 25 Corridor by midday. Spotty critical conditions were seen in Baca County as well, but further research into surrounding observations indicated that it was not widespread enough.

Tonight and Tomorrow...Upper pattern remains somewhat the same over the next 24 hours, and to be honest into this weekend, which means breezy northwest flow aloft across the region with above normal temps during the day and mild overnight minimums.

First, ongoing Red Flag Warning will continue until 5 PM. Models indicate by then winds should start to gradually diminish, and combined with cooling temps and rising RH levels, will drop the area out of criteria.

Overnight low temps tonight along the eastern slopes of the eastern mts should remain somewhat mild tonight with the W-NW warming downslope flow, but a weak cool front is forecast to back into the plains overnight into early tomorrow morning. Therefore, plan on minimum temps tonight in the mid 30s to around 40F for the east slopes and along and west of I-25, mid 20s to around 30F for the eastern plains as well as for the lower AND upper Arkansas River Valley, and teens for the San Luis Valley.

Friday should see less cloud cover, though mt clouds will linger over the Pikes Peak region. Dry conditions prevail, though the plains will likely be under a light easterly wind regime due to the previously mentioned cool front. Look for highs in the 40s for the San Luis Valley, 50s for the Upper Arkansas River Valley, and mid 50s to around 60F for the plains which is still around 10 degrees above seasonal normals. Moore

LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/

Issued at 222 AM MST Thu Dec 11 2025

The weather pattern will be dominated by northwest flow aloft with brief dry cold front intrusions into the southeast plains through Saturday which retreats to the east on Sunday as shortwave ridging aloft translates in and lee troughing re- establishes. Even with the frontal intrusions temperatures across the plains remain above normal with mixing offsetting any effects from cooling especially on Saturday. Otherwise, it will be breezy at times in and near the mountains during the afternoon as northwest flow aloft mixes down, but speeds do not look as strong as recent days.

A weak Pacific trough moves through the Great Basin into the 4 corners region on Monday but it is pretty moisture starved in all of the long range models. The best it will offer is some increase in cloud cover.

Zonal flow sets up for the latter half of the work week which will bode for above normal temperatures and breezy to windy conditions in and near the mountains each day. Passing systems to the north will spread some light snow into the central mountains at times. -KT

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 420 PM MST Thu Dec 11 2025

VFR conditions are expected at COS, PUB and ALS throughout the next taf period. Breezy northwest winds at COS and PUB to diminish by sunset, with weak north to northwest winds continuing at the terminals as a weak, dry cold front pushes south and west across the plains through the late evening. This will bring weak east to southeast winds back to the terminals early Friday morning, which will persist through the day. Winds at ALS will be generally light and variable through the taf period.

PUB WATCHES/WARNINGS/ADVISORIES

Red Flag Warning until 5 PM MST this afternoon for COZ226>230.
