KEY MESSAGES

- Dry and breezy weather with at and above seasonal temperatures into early next week.

- Chances of light snow showers possibly returning to the central mountains into the middle of next week.

- Above normal temperatures and dry weather persist through the extended forecast for all other areas.

SHORT TERM /THROUGH TONIGHT/

Issued at 212 AM MST Fri Dec 12 2025

Water vapor imagery and upper air analysis has moderate northwest flow across the Rockies, with upper level ridging in place across the West Coast, as occasional short wave translate through the stronger west to northwest flow in place across the Pacific Northwest through the Intermountain West and into the Upper Midwest at this time. Water vapor and satellite imagery indicates embedded mid and high level moisture within the northwest flow, leading to periods of wave clouds across the Rockies.

No big changes in the forecast for today and tonight, as an embedded short wave translates out across the Northern High Plains early this morning, sending a dry, weak backdoor cold front across the eastern plains. This will keep east to southeast low level flow in place across the plains through most of the day, with winds becoming more westerly through the late afternoon and evening, as lee troughing develops ahead of the next embedded wave translating across the Northern Rockies into early Saturday morning.

With that said, dry conditions are expected through the period, with highs mainly in the 50s across the plains (which is much cooler than yesterday, but still above seasonal levels) under partly cloudy skies. Temperatures further west across higher terrain should be similar to previous days in the 30s, 40s and 50s. Increasing flow aloft and lee troughing will help to develop gap flows across the higher terrain along and west of the I-25 Corridor overnight, which will keep lows mild in the 30s and 40s across the banana belt, with a mixture of 20s and 30s across the plains, coolest in the low Arkansas River Valley, along with a mixture of teens and 20s across the higher terrain.

LONG TERM /SATURDAY THROUGH THURSDAY/

Issued at 212 AM MST Fri Dec 12 2025

Saturday...

Increasing flow northwest flow aloft will mix out across the plains through the morning, with breezy gap flows and much drier air leading to spotty critical fire weather conditions across the portions of the I-25 Corridor late Saturday morning, before another dry backdoor cold front moves across the plains, shifting the winds more easterly direction through the afternoon. The timing of this front remains in question, with the latest guidance quickly warming temperatures into the 60s across the plains early Saturday afternoon, before slowly cooling behind the front into the late afternoon. Further west, dry conditions with at and above seasonal temperatures in the 30s, 40s and 50s will persist on Saturday.

Saturday Night and Sunday..

We cool back down from Saturday into Sunday somewhat, especially for overnight lows. Most areas will be closer to normal, with temperatures dipping into the teens for mountain valleys and teens to 20s for the plains. Our highs on Sunday will also be cooler than Saturday, though still several degrees warmer than normal. The San Luis Valley looks to warm into the mid and upper 40s, with 50s and low 60s spreading across the plains. Sunday will be very mild, with dry but not windy conditions, and mostly sunny skies. Overall, a very nice weekend unless you are craving wintry weather.

Monday Onwards..

Still no mention of winter through this section of the forecast either. A weak trough looks to push in from the four corners region on Monday, dipping down into Texas by Tuesday, but this system is not forecast to bring much in the way of moisture. We could potentially see some cloud cover and a slight dip in temperatures as its passing, but that may be the only noticeable change in weather for us. After it passes, zonal flow sets up for the second half of the work week. Increasing westerly flow aloft will lead to another bout of above normal temperatures for at least Wednesday through Friday, along with breezy winds over and near the mountains. At this time, humidity values look to remain high enough that critical fire weather may not be an issue, but this trend will need to be closely monitored, especially for our gap flows on Monday and Tuesday as the dry trough is passing through. One other result of prolonged westerly flow would be chances for light snow across west facing slopes of the central mountains, though without any major forcing or moisture coming in, accumulations would be negligible.
