This Week in Colorado Weather: September 7, 2026

September 7, 2026 / / 0 Comments

The shortened work week arrives with a bit of a plot twist as Tropical Storm Marie sends a surge of deeper moisture straight into Colorado. That boost will keep scattered storm chances alive through Tuesday before a midweek cold front briefly dries us out and knocks temperatures back into more comfortable territory. But the break won’t last — late‑week heat is set to rebuild quickly, and weekend guidance is already hinting at yet another unsettled pattern trying to form, with a fresh plume of subtropical moisture lurking on the horizon. This summer’s stubborn, underperforming monsoon looks determined to limp well into September. Read on as we unpack the setup and what it will mean for weather along the Front Range this week.

August 2026 Weather Review: Boulder Notches 2nd Hottest August on Record and 15th Consecutive Month Warmer Than Normal

September 4, 2026 / / 0 Comments

August 2026 was a month defined by brutal heat, episodic monsoon relief, intermittent smoke, and continued climatological extremes across the Front Range, with most of the West extending a long‑running warm anomaly that has defined the past year and a half. Boulder notched its 2nd‑warmest August on record, capping 15 consecutive months averaging above‑normal temperatures, and even tied its all‑time record high of 104°F during one of several extreme heat pulses. During the month, new records were also set for the number of 95° and 100° days in a single calendar year — a clear marker of how historically persistent the heat has been. The month also featured a brief but meaningful uptick in monsoon moisture, especially in the southern Denver Metro area, where localized downpours provided slight drought improvement and a temporary break from the otherwise parched pattern.

Here’s a graphical look at how August 2026 unfolded across Boulder, Denver, and the Front Range — and how it compared to climatology.

A stubborn late‑summer pattern refuses to budge across the West, and Colorado is once again caught in the middle — but this holiday weekend comes with a tropical twist.

If you’re heading outdoors for Labor Day weekend, especially in the Mountains, you’ll want to keep an eye on the sky — the atmosphere has a few surprises lined up.

A Monsoon in Name Only: Inside One of Colorado’s Hottest, Driest Summers on Record

September 2, 2026 / / 2 Comments

Summer 2026 is beginning to wrap-up, but before we close the books on one of Colorado’s most punishing warm‑season patterns in recent memory, we’re taking you through the full story — from the record‑warm, snow‑starved winter that set the stage, to the monsoon that never quite cohered leaving fuels critically dry statewide, to the heat dome that kept both day and night historically warm.

Read on as we break down why Boulder’s rainfall never materialized this summer, why Denver fared only marginally better, how nearly 250,000 acres burned statewide, and why half of Colorado is now in Extreme or Exceptional Drought. This summer has certainly been one for the record books, in more than one way.
