You got your geography messed up. Colorado Springs "COS" is Southern Central CO where Arvada is Northern Denver Metro. And the weather you are describing is common all over the state. The mountain range makes for some real interesting weather. We had 90deg weather one day, 60s the next day, just a few days ago. Colorado has some of the best weather. Love it here.I used to live in COS. I remember watching the news in the morning, and in the Springs we would have a low of 10 degrees. While to the south in Arvada, it would be -20 or less. Arvada is the only place I know that the temperature can go from high 80s to near freezing in the same day, in the summer time. Houston, has terrible weather but it is predictable.
