August brought welcomed change to the Front Range with the elusive American Southwest Monsoon finally making a late appearance. While much of the area ended with below normal rainfall in August, it was notably wetter than months prior leading to a slight improvement in the regional drought. It was also hot in August, with overall temperatures and the number of 90-degree days landing above normal. Here’s a quick and colorful graphical recap of our weather during August and how it relates to climatology.

📊 #Boulder is up to 2.22" of rainfall in August, the wettest August for the city since 2008. That will likely be the monthly total as we'll be bone dry the rest of the week. For reference, the entire May-June-July period spit out only 0.97" of rain, an all-time record low #COWx pic.twitter.com/MvSwi31gXJ

Nice and informative plots. Presenting the entire context is critical, and you do that very well.
Thanks. If you have any other ideas for plots, let us know. We try to provide as much data and historical context for the month here as possible.
The plots with the climatologies are great, as are the year-to-date timeseries. The scatter plots could emphasize the current month a bit more, but I really like that presentation. Great work!
