SHORT TERM /THROUGH SATURDAY/

Issued at 239 PM MST Fri Jan 30 2026

Tonight: For Friday night, quiet weather continues for south central and southeastern Colorado. Northwesterly flow will be in place across the region, and given the lack of any major forcing, along with only minimal moisture in place, dry conditions are expected. The exception to this may be across the eastern plains, where freezing drizzle will be possible as a shallow backdoor cold front sags across the eastern plains tonight. Confidence in this though is very low (10%) at this time, as weak ascent and drier surface conditions may hinder efficient drizzle development. If freezing drizzle were to develop, accretion would be minimal, though slick spots on roads couldn't be ruled out. In addition, given sub- freezing temperatures and pockets of low level saturation, patchy freezing fog is expected across the plains, with higher confidence (60%) in development outside of any freezing drizzle. Any ice accretion from this would also be expected to be minimal. Beyond all of that, light winds around and less than 10 mph are anticipated, with a cool night for many. Looking at temperatures, much of the region will fall to around and slightly below seasonal lows, with the plains dropping into the 10s, and the valleys and mountains into the 10s and single digits.

Tomorrow: Heading into Saturday, the quiet weather trend continues another day for south central and southeastern Colorado. Northwesterly flow will remain in place, and like previous days, given the lack of major forcing, and only modest moisture in place, dry conditions are anticipated. Otherwise, light winds around and less than 10 mph and mostly clear skies are expected for the region. As for temperatures, near to slightly below seasonal values are anticipated, with the plains rising into the low 40s to low 50s, the valleys into the 40s, and the mountains into the 20s and 30s. The coldest air for the plains will settle into the Arkansas River Valley and far eastern plains as the denser and colder air behind Friday nights cold front remains in place.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/

Issued at 314 AM MST Fri Jan 30 2026

Saturday-Sunday...

An upper-level ridge will continue building overhead this weekend, leading to more dry and warm conditions. Highs on Saturday will likely climb into the 40s-50s, while better warming and some downsloping west winds on Sunday push temperatures into the 50s to low-60s. With mostly clear skies, overnight lows will remain cold both Saturday and Sunday Night, with teens-20s over the plains and single digits to low teens over the San Luis Valley. Dry conditions are expected both days as well.

Monday Onwards...

The upper pattern starts to shift on Monday, with the ridge flattening out and increasing westerly winds aloft. Though there is still some uncertainty in the models, Monday looks to be the driest and windiest day in the next week, with the highest chance for critical fire weather conditions. That being said, despite the dry conditions, will have to see how models resolve wind gusts as we get closer to date, with only marginal critical conditions in the long- term forecast as of now.

Long-term guidance suggests a quick-moving wave passing just to our east around the Tuesday-Wednesday timeframe, which could lead to a quick round of precipitation, mainly a mix of rain and snow. Temperatures also cool down 5-10 degrees both days behind a passing cold front. Timing and magnitude of any incoming pattern shifts will need to be better resolved in the coming days, with current guidance divided on the speed of the upper-level pattern. But overall, expect warming and drying through Monday, followed by cooler and briefly wetter conditions around midweek.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 510 PM MST Fri Jan 30 2026

Backdoor cold front across eastern CO this evening will usher in some lower clouds along with fog potential and possibly spotty freezing drizzle across the eastern plains this evening through early Sat morning. Low clouds are mentioned for KCOS tonight starting at 06z and possibly lasting through 20z. KPUB has a greater chance for IFR conditions due to low cigs and reduced vsby as cold air follows the Arkansas River west.

The remainder of the forecast area, including KALS, will have VFR conditions over the next 24 hrs.
