It is looking increasing likely that the remainder of September will be completely dry with above average temperatures. Pueblo, Denver, and Cheyenne are all on track to have the warmest September on record. Boulder has a few warmer Septembers from the 1940s-1960s, but that has mostly to do with the poorly sited rooftop thermometer those years that introduced a large warm bias in the daily low temperatures. Denver has had only 0.04″ of precipitation, and Boulder is at 0.06″. This is among the driest for both locations, but both locations have had a few Septembers with no measurable precipitation (in Boulder 1922, 1943, and 1944 only saw a trace).
We are not likely to set any daily record highs this weekend, but we will get close. The records highs for Denver on Saturday and Sunday are 90 and 92, and for Boulder the records are 89 and 92.
Don’t forget the total lunar eclipse Sunday evening from 8:11 to 9:23 MDT. The moon is in the part of it’s orbit that is closest to Earth– a supermoon. A supermoon total eclipse last occurred in 1982 and is not due again until 2033.
