This coming week will be colder with some snow Monday and/or Monday night. We are not looking at bitterly cold weather, but even in the lower elevations daytime temperatures might not get out of the 30s for most of the week.
It looks like snow will develop in much of the Front Range region Monday morning, with generally cloudy conditions and occasional snow or flurries lingering into Tuesday. Light to moderate amounts are likely on Monday.
General accumulations: 1-3 inches
Local accumulations: 3-5 inches in some areas, mainly north of Denver and along the foothills (Boulder, Fort Collins, Cheyenne, Nederland, Estes Park).

Tonight and Wednesday
A cold front this evening will bring a blustery cold wind and some accumulating snow in the mountains. For the Front Range foothills and plains, most areas will see little or no accumulation, but there may be some snow showers around. It will be cold Wednesday, but mainly dry, with north winds lingering for longer east of I-25.
Thursday through Saturday should be dry. It will still be chilly on Thursday, but not as cold as Wednesday. By Christmas Day afternoon temperatures should be a bit above average. The chances for a white Christmas are rather small for the Front Range urban corridor. The next change to colder and more unsettled weather will probably arrive on Sunday, but that is also looking like a storm that will have minimal impacts for the eastern foothills and plains.

Some clouds and maybe some flurries or light snow will be around today, but then look for a dry weekend, with temperatures a little milder each day through Monday.
The snowfall potential is pretty minor. In fact, little or no measurable snow is the most likely outcome for many parts of the Front Range. Where it does snow more substantially (southern metro Denver, Castle Rock, and higher mountains) we are probably only looking at around and inch.
Snowfall is running below average this season in most areas, although not nearly as low as some past years. Remember that we got an early start this year in September. The long range pattern is not looking promising for any major snowstorms.
Temperatures in the lower elevations are likely to rise into the 50s Sunday and Monday. The winter solstice is at 3:02 AM MST Monday, but they day won’t be nearly as wintry as it could be this time of year. Occasional gusty Chinook winds might be the price to pay for the warmer weather. The next cold front is due in late Tuesday, and right now it’s looking like another dry one.

It’s true, another weak storm system is likely to bring another layer of snow this evening, possibly starting late this afternoon, and be gone before morning. For most places this will likely be another 1-3 inches.
Sunday should bring some sunshine even though it will be chilly. But clouds will be on the increase again Monday as yet another weak storm moves through. It’s not clear yet if that storm will bring more snow, but if it does, it should another fairly minor snowfall late Monday or early Tuesday.
Sunday night is the annual Geminids meteor shower (one of the two best meteor showers of the year). The good news is that there will be no moon this year. The bad news is that it is very likely there will be cirrus clouds obscuring the sky, especially after midnight when the meteors peak.
5:45 AM MST, Wednesday, December 9, 2020
Today will be the last day in our current stretch of unseasonably warm weather for a little while. Tomorrow will be colder, but not too bad. Then tomorrow night through Saturday night are likely to have frequent cloudy periods, some periods of snow, and daytime temperatures not doing better than the 30s even in the low elevations.
The first period of snow will probably be Thursday night and Friday morning with about 1-4″, most likely in and near the foothills.
A series of weak Pacific storms won’t allow a complete clearing out Friday. There may be lulls and some breaks in the cloud cover, but additional periods of snow (mainly light) appear likely through Saturday morning. Even on Saturday night there may be one more weak disturbance bringing at least some clouds, and maybe some more light snow. Through all of that a few more inches are likely.
So a big snowstorm does not appear to be bearing down on us, but a multi-day period of cold and occasionally snowy weather does seem to be on the way.
