It s the snowiest month, it could be a blizzardit could also be 60F, hard to predict Colorado. But indeed, count on snow.
i know last year in march girls (including me) wore shorts to school in march. cuz it was like 60 or 70. years before its been freezing. its so hard to predict. i recomend waiting until soon before you go and go to weather.com and searching for the zip code of where your hosts live so you can get a general idea :)
The first answer is correct. 10--20 inches of snow on one day and 65 degrees all the next week. It melts fast.
