KEY MESSAGES

- Strong winds finally back off later today into tonight.

- Very warm on the plains through Christmas, trending cooler at the end of the period.

- Pattern shift is expected to bring increasing snow chances in the mountains towards Christmas.

SHORT TERM /THROUGH SUNDAY/

Issued at 221 PM MST Sat Dec 20 2025

Strong zonal flow remain in place across the region, with slightly cooler temperatures setting in. Meanwhile, snowfall will continue over portions of the central mountains through the rest of the day. Total accumulations through this evening are still heaviest over northwest Lake County, while the rest of the Sawatch and Mosquito ranges receive a few inches. Meanwhile, the rest of the area will remain dry.

Winds will finally start weakening over the area tonight as the jet aloft shifts northward , with some modest upsloping over the mountains/plains interface. Although, winds aloft, above about 5,000 feet, remain gusty and mainly out of the west due to the greater synoptic flow. With the absence of any strong downsloping out east, overnight lows will be much colder in some areas tonight, typically in the teens-20s at most locations, though low-30s may linger right along the terrain.

Warm temperatures return on Sunday, though we may be a few degrees cooler than today. Mid-level clouds will stick around, but are expected to slowly dwindle as the day goes on. Highs will be in the 50s to low-60s over the plains and valleys. Winds will be much lighter, with a few gusts from the south over the plains, while the area remains generally dry.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/

Issued at 206 AM MST Sat Dec 20 2025

Well, there is good and bad (weather) news in the long range. The bad news is it is NOT going to feel like Christmas over the plains this week. The jet is going to remain to our north over Wyoming and mid level flow is going to come out of the west-southwest. Max temps over the plains on Sunday in the 55 - 65 range will be replaces by temps in the 60s and 70s (with possibly at 80 here and there) through this week. These temps are ridiculously way above normal as max temps on the plains should typically be in the 40s. I expect we will see some records fall Christmas week, with the warmest temps this Monday.

The good news is moisture will be increasing with the southwest flow and the mountains along all of the CONTDVD should see snow start to ramp up Perusing the DESI guidance shows the snow starting to ramp up Christmas Eve along the Divide and lasting into the weekend. Overall amounts dont look all that high(up to 2 feet through Xmas-eve into the weekend), but any accumulating snow is good snow in the mountains.

It does appear it will continue to get more "troughy" over the west XMAS weekend into the following week, and cooler, possibly wetter weather should move into all of the region. \/Hodanish
