Colorado Climate

My first memories of Colorado go back about 35 years. I visited off and on for more than 20 years before moving here in 1983. I don't know why, but I've always been interested in the weather. Even though mountain weather is notoriously unpredictable, there are discernible patterns.

I like to think in terms of a base climate about which typical variations occur. Colorado usually has dry, fair weather, and it's not unusual for a given location to go many weeks or months without any real precipitation. These long stretches are punctuated at intervals of varying length by periods when the weather seems "broken". This generally happens when we're stuck under the storm track, or when it's wiggling back and forth over us (which is most likely to occur near, or in the month following, the equinox). The chief symptom of this is an over-abundance of storms (duh) and things changing, sometimes wildly, from day to day, or sometimes hour to hour. Both the amplitude and the duration of variations can themselves vary.
