During July 2021, the summer monsoon pattern tended to favor areas further west with persistent high pressure holding over Colorado. Despite this, with a little luck involved, Boulder managed to notch a Top 20 wettest July, while most of the Front Range was very dry. Other weather highlights during the month included persistent smoke from new fires burning in the Pacific Northwest, multiple bouts of triple-digit heat, highly localized flooding in portions of Boulder, and frequent mudslides across the Mountains which has left Interstate 70 indefinitely closed near Glenwood Springs. Here’s a quick and colorful recap of our weather during July and how it relates to climatology.

The important result, however, was a significant improvement in the drought across northeast Colorado. Here’s a quick and colorful rundown of our weather during April 2021 and how it relates to climatology.
