Now let’s jump into the forecast. The forecast for today will focus on the aforementioned low pressure system, which is currently over southeastern Wyoming and northern Colorado. This system will continue to move east-northeastward from this afternoon and evening. As it does so, northwesterly flow will ensue across the High-Country. That will spell out upslope flow across the mountains with favored ski slopes being those along and north of I-70 west of the Divide. Some spill-over will also occur for areas just east of the Divide.

Below shows the forecast precipitation from this afternoon and tonight across Colorado from the NAM model. This map shows a swath of snowfall across northwestern Colorado. The favored areas should be Steamboat, Vail, Winter Park, Beaver Creek, and Copper. Of course, this system does not look to be strong, but expect light to moderate snow showers from today into tomorrow morning. A general 2-4 inches of snow can be expected in areas along and north of I-70. This will lead to powder days for several ski resorts on Tuesday.
Forecasted radar reflectivity from the NAM for Tuesday morning
Forecast snow amounts today into Tuesday morning
| Steamboat: 3-6″ | Eldora: < 1″ | Winter Park: 2-4″ | Vail: 2-4″ |
| Beaver Creek: 2-4″ | Loveland: 1-3″ | A-Basin: 1-3″ | Keystone: ~ 1″ |
| Breckenridge: ~ 1″ | Copper Mountain: 1-2″ | Aspen/Snowmass: 1-2″ | Crested Butte: ~ 1″ |
As we go into Tuesday afternoon, through Thursday, the weather pattern relaxes with little to no major storms on the horizon. Sunny skies can be expected for the High Country Wednesday through Thursday. The next possible system would be Friday. Below shows the 500 mb vorticity from the GFS for Friday afternoon. It shows a weak trough of low pressure over southern California. This trough is expected to dive south of Colorado over the upcoming weekend. Also, moisture is limited with this system so we do not expect much of a snow threat on Friday, but will keep you updated if things change 🙂
