September weather brought a little bit of everything to Colorado.
The first week of the month brought record heat. Both Colorado Springs and Pueblo saw their all-time September high on the 6th, of 97, and 103 degrees, respectively.
A couple of days later Pueblo tied the earliest recorded freeze on the morning of the 9th with a powerful shot of cold air. Southern Colorado saw the first snow of the year at the beginning of the month after several decades of snow-free Septembers. This was the earliest first snow in Pueblo, but not for Colorado Springs.
After that tumultuous first week, the weather pattern settled into a bone dry hot streak. The majority of the month was above average with only one or two days with rain after the snow. Colorado Springs and Pueblo both saw record high temperatures on the 25th and 26th.
September was another month of wildfire activity on the increase in the Rockies and west coast, which brought air quality down significantly. We spent most of the month with moderate or unhealthy air quality due to particulate matter from the smoke. Warmth and high pressure helped increase ozone levels which further decreased air quality.
