KEY MESSAGES

- Warming trend develops today, continuing through next Saturday, with little precipitation in sight, sticking to mountain and highland areas.

- Rebuilding ridge of high pressure may provide renewed bouts of low clouds and fog at times this coming week.

SHORT TERM /THROUGH TUESDAY/

Issued at 336 AM MST Mon Jan 26 2026

Shortwave trough swinging through today will bring increased cloud cover, slightly breezy winds, and slight chances for snow showers areawide throughout the afternoon and evening. High pressure will rebound Tuesday with the trough axis shifting directly overhead later evening. Temperatures will gradually warm through Tuesday, with daytime highs increasing by several degrees each day.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Issued at 146 PM MST Sun Jan 25 2026

Upper ridge briefly rebuilds for Tuesday, but another quick shortwave shifts through on Wednesday. The NBM has been waffling back and forth about the potential for very light precipitation across some higher elevation areas. Confidence remains extremely low, and the latest NBM is only depicting extremely light PoPs in some portions of the central mountains. The GFS depicts a repeat on Thursday, with stronger potential for the ridge to flatten for potentially better chances at moisture for the weekend. Meanwhile, the ECMWF strengthens the ridge into the weekend. In general, the expectation is for dry conditions throughout the week with a warming trend. On days where the ridge axis manages to move overhead, we could see the potential for low stratus and patchy fog, and that could have some impact on temperatures for any particular day.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

Issued at 453 AM MST Mon Jan 26 2026

Weak shortwave today brings increasing high clouds and slight chances for isolated snow showers, although confidence is too low to include in any TAF at this time. Light winds will generally remain under 8 kts. High pressure will rebound Tuesday.
