An area of snow is currently moving south across southeastern Wyoming and the northeastern plains of Colorado. That may affect parts of the Front Range urban corridor later this morning or this afternoon. Some areas will totally miss out, but where it does snow there may be an inch or two. This is the kind of setup where DIA has a better chance for snow than areas closer to the foothills.
Dry weather is likely to finish out the week, with milder temperatures by the end of the week.

As the storm about to move through the region approaches, it appears the most significant snow will likely stay to the south and east of Denver. There is still some uncertainty about whether the storm will come together fast enough to shift the heavier snow northwest into Denver-Boulder, but that is only a small chance. Right now it appears snow will spread over the area early Sunday, but shift south and east during the day.
Most likely accumulation:
4-8″: Palmer Divide region, Colorado Springs, far south suburbs of Denver.
3-5″: South side of Denver
1-3″ Denver, Boulder
less than 1″: Fort Collins, Cheyenne
Another cold front late Monday and Monday night will continue the cold weather into midweek. There may be some additional snow with that front, but it appears that there will be little or no new accumulation.

The next in a series of frequent storms will be moving through the Front Range region on Sunday. This one is a closed circulation and the timing of the development and intensification will make the difference between a near miss and a significant snowfall.
The European model, one of the best performing, forecasts only a brief period for snow along the urban corridor Sunday morning (only minor amounts) and then more significant snow and wind farther out on the plains. The U.S. model has the storm develop a little sooner and therefore produces more significant snows along the Front Range. I will update tomorrow morning on the development of the storm.

There are a few chances for light snow accumulations along the Front Range between now and early Thursday. There are no big storms or widespread upslsope likely that would favor heavy snow. Instead it looks like it will be mainly a dry period that is punctuated with periods of cloud cover and some snowfall as some weak disturbances move across the region.
The most likely period for a dusting to 2 inches is tonight in very early Tuesday, and again late Wednesday afternoon and evening. There may be some parts of the region that don’t get any measurable snow. So nature is trying to keep a snow cover in place a little longer!
11:20 AM MST, Friday, February 14, 2020
The eastern foothills and plains should enjoy dry weather this weekend, but the possibility of sporadic gusty west winds near the foothills exists. For the west side of the mountains, the chance for snow returning increases on Sunday.
Mountains and West Slope
Significant snow (some areas more than a foot) is likely beginning Sunday and continuing into Monday for the mountains and west-facing slopes. Expect winter travel conditions at the high passes starting on Sunday.
Eastern foothills and plains
The Front Range urban corridor and adjacent foothills should have a dry weekend. Temperatures for Denver-Boulder-Fort Collins should approach 50 today and Sunday. Saturday will probably be 5-10 degrees colder. There is a chance for some localized areas of gusty west winds in and near the foothills, especially late today, and again early Sunday. The winds are not likely to be widespread. Blowing snow may occur in windy areas, although the warmer temperatures should create a wet layer at the top of the snow which will reduce blowing potential.
The next chance for snow is on Monday or early Tuesday. However the trend for this next storm has been toward less snow than it was looking like yesterday. For now the chance for snow is still there, but it’s possible if the current trend continues that we will just have a change to colder temperatures on Monday without much new snowfall.
Noon MST, Wednesday, February 12, 2020
I just got back into town and missed the latest in a series of snowfalls this month, the one Monday night. More snow will likely fall late this afternoon or evening in and near the foothills, making it the 7th date this month with measurable snow for those areas.
Accumulations will generally be minor:
0-1 inch Fort Collins, Longmont, DIA, Colorado Springs
1-3″ Denver-Boulder metro.
3-5″ in some localized areas in and along the lower foothills in Jefferson and Boulder counties
After that we should have a stretch of days with no snow lasting through the weekend.
The Boulder climate station is up to 30.1″ of snow for February, and that’s already more than twice the monthly average. DIA snowfall for February is running close to 200% of average as well.
3 PM MST, Saturday, February 8, 2020
There will be a couple more chances for snow in the Front Range region, first on Sunday and then again late Monday afternoon or night. Both will be from upslope type events with storm centers passing well to the south of Colorado. The best chance for snow is along and south of a line from DIA to Lyons, with a smaller chance of light amounts north of that line. Monday night may see a major winter storm down near the New Mexico border.
0-1″ Fort Collins, Cheyenne, Longmont
1-3″ Denver metro and Colorado Springs
3-5″ in some localized areas in and near the lower foothills and Palmer Divide
Late Monday/Monday night: generally a 1-4″ event appears possible, more south of Colorado Springs
