SHORT TERM /THROUGH TUESDAY/

Issued at 156 PM MST Mon Dec 29 2025

Tonight through Tuesday...

Weakening northwest flow remains aloft as high pressure continues building into the region from the west. Clear skies and relatively light winds will net us another cold night tonight, with lows forecast in the teens to around 20 over the eastern plains. Meanwhile, the high valleys will likely stay in the single digits, particularly the San Luis Valley, which may hover close to zero. Not much change to Tuesday's forecast either, with highs climbing into the mid-50s over the plains and high-40s to near-50 for the mountain valleys. No precipitation is expected in our area.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/

Issued at 222 AM MST Mon Dec 29 2025

Tuesday night through Friday...quick moving upper level riding will spread across Colorado Tuesday night through Wednesday, before an upper shortwave trough impacts the region. We will continue to see mild and dry conditions during this period, with overnight lows Tuesday night into Wednesday morning mostly in the 20s on the Plains, with single digits across the San Luis Valley. Temperatures will continue to warm on Wednesday, with upper 50s to mid 60s on the Plains, and near 50 over the San Luis Valley.

The upper shortwave will approach the area Wednesday night, and move quickly across southern Colorado on Thursday. Moisture will increase with the upper shortwave, with snow spreading along the Continental Divide by Thursday morning. Orographic southwesterly flow aloft will favor the San Juan Range, where the highest snow accumulations are forecast. At this time, snow amounts look minor, with less than 5 inches over the San Juans, and less than 3 over the La Garita Range and Central Mountains. The Plains are forecast to remain dry and mild, with highs reaching the upper 50s to lower 60s. This is a quick moving system, and will quickly eject the northeast Thursday night, with snow coming to an end across the higher terrain Friday morning to early afternoon. Temperatures will remain warm on the Plains for Friday, with continued 50s and lower 60s.

Saturday through Monday...another quick moving upper ridge will spread across the region Saturday, before the next upper wave looks to impact the region by early next week. Wind looks to increase across the area late Saturday and continue into Sunday. There are some signals in the model guidance that winds could be quite gusty late Saturday night into Sunday morning along the Eastern Mountains. Snow looks to hold off along the Continental Divide for the weekend, with another quick shot Sunday night into Monday. Temperatures will remain warm over the weekend, with 50s and 60s for most of the lower elevations, with a cold front arriving by Monday, which will knock around 10 degrees off forecast highs. Mozley
