The next storm will bring snow to all of Colorado Saturday night and Sunday. The southern half of the state will see the most snow on Saturday night, while the northern half including I-70 will see the best accumulations Sunday morning. Most of next week will be dry and warmer.
It's super cold this morning and the state looks like a winter postcard with snow covering nearly all mountains, valleys, and trees. What a gorgeous sight!
There might be some clouds and crystals in the air today, but there will not be any snow accumulation.
The next storm moves toward Colorado from the southwest on Saturday. This storm is weaker and has less moisture than the storm on Tuesday night. However, temperatures during the upcoming storm will be near perfect for efficient snow production, so this positive factor might somewhat cancel out the negative factors of less moisture and energy.
For the southern mountains (Telluride, Silverton, Durango, Wolf Creek) and the south-central mountains (Crested Butte, Irwin, Monarch), snow will increase late Saturday afternoon and become heavy Saturday night. Accumulations for these areas could be 8-12 inches or more by midday Sunday.
For the Aspen and Sunlight areas, snow will become heavier late Saturday night into Sunday morning with total accumulations around 4-8 inches.
Along I-70 and north to Steamboat, an inch or two of snow might fall Saturday night, but the best snow won't start until 2-5am Sunday morning and will last through midday Sunday. Total accumulations will be about 3-6 inches, with more in spots that traditionally do well in northwest flow on Sunday AM. If the current timing holds, the Sunday AM snow reports might not show much, but good snow would fall after these 5am reports and last through late morning.

It'll be extremely cold once again on Monday morning, then we'll warm up through next week. There's a chance for another storm on Friday December 13th, but the models are now trending toward a splitting storm with energy going north and south of Colorado, and if this holds it won't lead to a big snow producer. I'll keep an eye on it. Maybe that's fitting for a Friday the 13th storm...
Enjoy the fantastic early-season conditions, and great to see a lot of folks at Neptune Mountaineering in Boulder last night!
