Snow coming to Den/Bou Mon night into Tue (a little bit more for the mountains as well)

01/05/24 12:30pm: The active weather pattern continues. Den/Bou (and Ft. Collins, Springs and Pueblo) you ready for some snow! Models are consistent now showing a cold upslope event for the front-range on Mon night into Tue mid-day with several inches of snow for the urban corridor. Also some more snow coming to central mountains as well (including southern CO).

Timing:

• For Den/Bou and the front-range a stronger cold-front will move in from the north after 5pm Mon. Then snow likely from about 8pm Mon to 2pm Tue

Amounts:

• Generally 2-5" for the urban corridor with highest amounts in/near the foothills and from Boulder county south (upslope notch: west of a line from Boulder to Parker will be favored). Foothills can expect 3-7" in spots

• It will be cold in Denver on Tue (highs in the low 20s)

For the mountains

Timing:

• For the north-central mountains after some more light snow today (through 5pm today), more snow expected from about 11am Mon through 8pm Tue

Amounts

• Generally 2-5" of additional snow for the local ski areas (I-70 mountain corridor), with highest amounts likely over the Front Range mountains along/east of the Cont. Divide (or maybe highest amounts near Vail, BC, Aspen again, depending on how the trough evolves)

• Highest amounts overall likely in the Western San Juans (Telluride, Silverton, Purgatory): 5-10" additional down there, Even Wolf Creek will get 3-6"

  
  

Looking ahead, models show the chance for a little bit more light snow over the mountains (maybe front-range) on Thu night into Fri am.

Then the next more significant storm slated to bring more heavy snow to the mountains from about 11pm Fri through 11pm Sat (01/10 to 01/11), but details need to be worked out for that.

Heading out for the Broncos game soon. Go Broncos, lets get into the playoffs!

First image shows the next storm system / setup with a large broad trough dropping in southwest of CO which will produce some cold upslope (northeast flow) on the front-range as you can see valid 11am Tue from latest GFS. Image 2-4 compare forecast additional snowfall form 5am this morning through 5pm Wed from latest 12z GFS, ECMWF and NAM models, take forecast snow amounts with grain of salt but gives general idea of what is coming (these models broad-brush the mountain valley features).
