Unpredictable Is an Understatement
Colorado weather is extremely unpredictable. I've literally walked somewhere in jeans and a t-shirt and gotten caught in a blizzard an hour later. Layers are a must and even if it's in the 70's it's not a good idea to go anywhere without a jacket. It snows a decent amount but it usually melts pretty quickly and hardly ever rains because it's so dry. As soon as it's decently nice everyone is outside from noon till dinnertime.
