SHORT TERM /THROUGH TONIGHT/

Issued at 227 AM MST Sat Jan 24 2026

Today and Tonight..

Temperatures have dropped near and just below zero across the plains, though much of the area has seen a lull in snow overnight. The main exceptions have been the eastern mountains and the Palmer. As of 2 AM, snow is redeveloping across our far eastern plains as well out near the Kansas border. As easterly upslope continues and better ascent arrives through the morning hours, snow looks to fill back in over much of the plains, especially where easterly upslope is favored, and along and north of Highway 50. Snow chances come to an end from north to south throughout the evening hours, with most of our plains looking to be dry by around midnight or so. Our southern mountains will likely hang on to snow through the morning hours, though rates will continue to decrease. No changes have been made to existing winter weather highlights, with the San Juans and Sangres still in a Winter Storm Warning through 5 AM Sunday morning, and much of the rest of the of the high country in Advisories through the same timeframe. Pueblo and Huerfano Counties are also in Winter Weather Advisories through 5 AM, though significant totals are not expected after midnight, especially for Pueblo County. Highest accumulations will remain along western portions of both counties closer to the higher terrain. Winds have subsided since yesterday, though dangerous travel conditions may still exist due to moderate and, at times, heavy snowfall. Please use caution if you must travel today, especially since dangerous temperatures are accompanying this snowfall. Apparent temperatures are in the teens and twenties below zero this morning, and are only expected to climb just above or near to zero throughout the afternoon for a couple of hours before falling back down into the double digits below zero again. These conditions can cause frostbite in as little as 30 minutes on exposed skin! Actual air temperatures today will range from near zero on our far eastern plains, to teens for the I-25 corridor, to 30s for the San Luis Valley. Arctic air makes its way into the Valley by tonight though, dropping temperatures back down below zero across the entire area. Otero, Crowley, and eastern Las Animas have been added to the ongoing Cold Weather Advisory for the plains, which is in effect through Sunday morning.me can cause frostbite on exposed skin in less than 30 minutes!

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 227 AM MST Sat Jan 24 2026

Models remain in decent agreement through midweek, with continued differences for late in the week into next weekend.

Sunday...southern Colorado will be between two upper systems, one departing to the southeast, while the next wave drops south across Wyoming. Snow will likely be ongoing early in the day across the San Juan Range and southern Sangre de Cristo Mountains into the Raton Mesa. This snow will be light, with little additional accumulation expected. This snow will end during the morning hours as the first wave departs the area. Undercut guidance for highs on Sunday, with snow cover on the ground and cold air in place across the region, most of the Plains will see 20s for highs, with the coldest readings near the Kansas border. These temperatures may be too high as well, and we will continue to adjust them as guidance comes in. By late afternoon, a few snow showers will likely begin to develop over the Central Mountains, east into the Palmer Divide as the next upper wave approaches the area.

Sunday night into Monday...the upper wave will continue to track south across Colorado Sunday night into Monday morning. As it does so, it will send another cold front south across the Plains, with a re-enforcing shot of cold air. Overnight lows will fall to near zero, to slightly below zero on the Plains. Northerly winds will make windchill readings fall in the 10 to 15 degrees below zero range heading into Monday morning. The coldest readings will be across the San Luis Valley where lows will fall to near 10 below zero, and a Cold Weather Advisory is in effect. This may need to be expanded into the Plains. As for snow, expect light snow to spread south behind the front overnight, clearing to the southeast early Monday morning. This will be a light, fluffy snow, with accumulations less than inch expected.

By Monday afternoon, broad northwesterly flow will spread across Colorado with warming conditions. Afternoon highs will be tricky, with most of the region quickly rebounding back through the 30s and into the lower 40s. These highs may be a bit generous with any snow on the ground, which may hold highs down a few degrees. But, it will be warmer!

Tuesday through Saturday...upper ridging will spread across Colorado Tuesday into Wednesday. This will allow for continued warming for mid week, with 40s Tuesday, and upper 40s to lower 50s by Wednesday on the Plains. There looks to be a couple of weak embedded disturbances in the flow during this period, which could produce very isolated snow showers over the Central Mountains, with little to no accumulation expected.

By Thursday and into Saturday, the models diverge significantly, and have changed from guidance 24 hours ago. The GFS drops a low south across the Intermountain West into Mexico, while another trough digs into the Central Plains, sending a cold front across the region. This would bring another shot of colder air and precipitation to the area. The ECMWF and Canadian drop a low, but much later in the period, and much drier and progressive than the GFS. Once again, given the uncertainty, did not stray from the NBM guidance for the later part of the extended period. Mozley
