Record highs are likely under this setup and we may even see some triple digits at times as well. The light at the end of the tunnel is a welcomed cold front currently scheduled to arrive on Friday.

July 2022 Graphical Weather Review: Many rounds of raindrops, but not much rain!

July 2022, a month that falls in the heart of monsoon season, ended up fairly hot and dry across much of the Front Range as a ridge of high pressure dominated our weather. Raindrops were a frequent occurrence, at least in Boulder, but ultimately they didn’t add up to much. A wave of thunderstorms towards the latter part of the month provided soaking rains to much of the Denver area, “saving”many locations from worsening drought for the time being. Here’s a quick and colorful graphical recap of our weather during July and how it relates to climatology.

Boulder surprisingly notched its first 100-degree day in over two years on Tuesday! Or did it?

On a day which should have been slightly cooler than recent times on paper, Boulder officially reached 100 degrees Tuesday afternoon. However, other reliable weather sensors around the city came in several degrees cooler and more in-line with forecasts. We take a look at the temperatures measured around the area and weight on what will ultimately go down in the books as a record high temperature and the city’s first triple-digit reading in over two years.
