temperatures in Crawford CO in early December

any comments for my upcoming trip the first week of December 2018?

Crawford, Colorado

Crawford is around 6,800ft above sea level, so from mid-November to late April it's best to pack in winter preparation. Daytime is below 40 as a "Usual" and Night falls significantly lower -- into the teens or below.

Layers are important if you plan on being outside. Bring a good pair of snow boots. In your vehicle -- bring snacks and water, and a blanket or two "just in case." Come in (as in back to where you're staying) from outdoor excursions before nightfall (it's very easy to make significant changes in your elevation and not even realize it, and the temperatures get Lower faster the higher you go). Don't be fooled with hydration.

If you've never been to Colorado -- I hope you enjoy your trip as much as I enjoy living here!

Hi, I don't like snow. I believe it should just snow in the mountains for the dedicated skiers. LOL. But below that where I am snow is not a good thing. Can you kind of give me an idea of just what weather Reno, NV will have this winter? 2018/2019. Certainly would appreciate it. Thank you!
