KEY MESSAGES

- Dangerously low wind chills across the plains and the San Luis Valley this morning.

- Warming back to at and above seasonal temperatures, with a few passing waves bringing chances of light precipitation and cooler temperatures for the middle and end of the week.

UPDATE

Issued at 805 AM MST Mon Jan 26 2026

Temperatures have slowly warmed over the last hour and will continue to do so through the rest of the morning, allowing wind chill values to also warm. Given this, the Cold Weather Advisories in place will be allowed to expire at the top of the hour.

SHORT TERM /THROUGH TONIGHT/

Issued at 217 AM MST Mon Jan 26 2026

Today and Tonight..

Mid/Upper trough continues to exit the region early this morning, with subsidence and drying supporting a quickly diminishing precip shield. Don't anticipate any additional snows in this setup, outside of a few flurries early this morning. Any lingering low stratus will also erode and scatter over the next couple of hours, with clear and dry weather expected for the remainder of the period.

The cold temperatures and low wind chills will be the main concern for the remainder of the morning, especially across the plains and San Luis Valley. The stronger winds which were in place last evening have since diminished, with lighter winds likely for the remainder of the morning. The light winds and clearer skies have allowed temps to really fall over the last couple of hours, and have lowered temps this morning several degrees in many spots, including locations along the I-25 corridor. Temps will likely lower further early this morning and despite diminishing winds, they will be strong enough to support rather low wind chills all along the I-25 corridor. So, have now included Pueblo, Huerfano, and western Las Animas counties in the Cold Weather Advisory.

Backing wind field today will support downsloping and warming across the plains. While cold this morning, should see temps rise to the 30s and even 40s today. With this warming and a rather dry air mass in place, will actually see critical RH values. Winds do also remain higher over and near the higher terrain into the afternoon. If it weren't for the snow/snow depth in place, would be concerned for the development of critical fire weather conditions.

LONG TERM /TUESDAY THROUGH SUNDAY/

Issued at 217 AM MST Mon Jan 26 2026

Latest model data supports continued moderate west to northwest flow aloft across the Rockies throughout the end of the week, with upper level ridging in place across the West Coast, and occasional short waves translating through the broad upper trough in place across the Central and into the Eastern Conus.

Embedded waves moving across the Rockies Tuesday and Wednesday could bring some light snowfall to the Central mtns, with a stronger wave on Thursday bringing the potential for precipitation across Central mtns into the southeast Plains Thursday and Friday. Will need to watch the evolution of this late week system, as there will be the potential for a much cooler airmass to back into southeast Colorado, as Canadian surface high pressure builds into the Northern and Central High Plains.

Upper level ridging looks to build into the Rockies through the weekend, with dry conditions and above seasonal temperatures expected into early next week.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1028 AM MST Mon Jan 26 2026

KCOS, KPUB, and KALS: VFR conditions are expected over the next 24 hours for all three TAF sites. For KALS, winds will remain relatively light through this TAF period. For KCOS and KPUB, winds are expected to remain light, though there may be a brief period this afternoon when diurnal mixing becomes established, and gusts to around 20 knots will be possible. Otherwise, dry conditions are anticipated, with increasing cloud cover for the later half of this TAF period.
