An impressive atmospheric river event currently hammering California moves onshore this week leading to gusty winds as well as rain and snow for Colorado Tuesday through Wednesday. Prior to that, warmth will abound to start the week with perhaps one final 80-degree day in the works. A quieter patten takes shape for the late week period and upcoming weekend which should make for excellent holiday activities.

These posts cover interesting weather phenomena from around the world, and won’t be specific to Boulder County. However, Earth is very diverse in the world of weather, so you will surely learn a thing or two.
September 2021 will go down as one of the overall hottest on record for the Front Range, and not much more. Other weather highlights during the month included a multi-day late-summer heatwave, continued smoky skies from the California wildfires, the first snow for many Mountain locations, dismal precipitation for much of the state, and one measly day that could pass for autumn. Here’s a quick and colorful recap of our weather during September and how it relates to climatology.
Meteorological summer begins on June 1st and runs through August 31st. With that end date now having come and gone, the official numbers are in for Summer 2021! Let’s take a look at how Boulder, Denver and Colorado as a whole did this summer in terms of temperatures and precipitation. We also check in on how our state fared compared to the rest of the country. If you like seeing data displayed on graphs and maps, this post is for you!
August 2021 across the Front Range was defined by its poor air quality and tenacious smoky skies which were mostly caused by out-of-state wildfires. Other weather highlights during the month included a rotating thunderstorm which prompted tornado sirens, lots of red smoky sunsets, a sprinkle of summertime snow in the Mountains, and the landfall of Category 4 Hurricane Ida sixteen years to the day after Hurricane Katrina. Here’s a quick and colorful recap of our weather during August and how it relates to climatology.
Sure…it has been fairly smoky already this week across our area, but it’s about to get a whole lot worse! An extremely smoke-laden airmass is poised to invade the entire state of Colorado late Friday night. The cause? An upstream low pressure system has been hard at work gathering up literally ALL the smoke from massive wildfires burning in California, the Pacific Northwest and southern British Columbia…and guess what? That low pressure system is headed our way!
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.
June 2021 began as one of the hottest and driest on record for the area, but ended on a cool and rainy note! Other weather highlights during the month included a slew of new wildfires across the Western Slope, a highly photogenic landspout tornado, multiple heatwaves, and poor air quality from near and distant wildfires. Here’s a quick and colorful recap of our weather during June and how it relates to climatology.
This week will feature a continuation of the dangerous, unprecedented heatwave in the Pacific Northwest, but cool and rainy weather in the Front Range. Go figure! Our temperatures will remain below normal through the week with daily chances for showers and thunderstorms, helping to alleviate but not remove wildfire concerns across the state. We also discuss the status of monsoon season, the active tropical eastern Pacific, and what may lie ahead for the Fourth of July weekend.
