This Week in Colorado Weather: June 1, 2026

June 1, 2026 / Ben Castellani / 0 Comments

Spring’s grip on our wet season is loosening, and the atmosphere is starting to hint at the drier pattern ahead — but not before we squeeze out a few more days of spotty storm potential. This week brings a mix of low‑end daily rain chances, early‑week severe storms, and a slow warm‑up that could push us toward our first 90° reading of the year by the weekend. Read on as we break down what to expect as we ride out this transitional stretch of early June.

This Week in Colorado Weather: May 25, 2026

May 25, 2026 / Andy / 2 Comments

A slow‑moving Pacific storm settling in across the West will set the stage for a classic late‑May stretch along the Front Range — warm afternoons, building clouds, and hit‑or‑miss late day showers and thunderstorms. While no day looks like a washout, the pattern does get more interesting mid‑week as deeper moisture sneaks in and storm chances tick upward. We break down what to expect, which day carries the best shot at rain, and how temperatures will swing as the broader system drifts our way.

This Week in Colorado Weather: March 16, 2026

Colorado may be easing into the week on a calm, cool note, but the atmosphere has no intention of staying quiet — and the shift ahead isn’t the one you might expect. While a major storm system pounds the eastern half of the country, a powerful ridge is quietly taking shape off the West Coast, ready to drive an exceptional, record‑shattering March heatwave straight into the Front Range. With gusty downslope winds on the way and the strong likelihood of multiple all‑time records falling, this week is all about the heat. How hot will it get and when will the heatwave end? Let’s take a look.

2025 in Review: Boulder’s Wildest Weather Moments of the Year Explored Through 100 Charts & Visuals

January 7, 2026 / BoulderCAST Team

2025 was one of those years where Boulder’s weather never seemed content with a single storyline. We opened with a bitter Arctic punch that delivered our coldest January in nearly two decades, only to swing into a summer packed with 90°+ heat, smoky afternoons, and the hottest day since 2012. The monsoon showed up often but rarely with much enthusiasm, fall dried out in a hurry, and our first snow didn’t arrive until November 29th — the latest on record by a country mile. Now that the dust (and smoke, and snow) has settled, we’ve pulled together a full graphical recap of the temperature swings, precipitation quirks, record‑setting moments, and long‑term trends that defined Boulder’s and Colorado’s atmosphere in 2025. If you want the full story behind the chaos — and a clearer picture of where 2025 truly landed — this is a fun one to dive into. Be warned, there really are 100 charts and visuals to explore. Enjoy!

August 2025 Graphical Weather Review: A hot, dry & smoky month saved by a cool & rainy finish

September 26, 2025 / BoulderCAST Team

August 2025 was on track to be our third scorcher in a row — hot, dry, and smoky — until a late-month shift brought in a welcome stretch of cooler, wetter weather. That pattern change helped balance things out across the Front Range, with most areas landing close to average for rainfall and just slightly warmer than normal overall. Still, it wasn’t all relief: the month packed in plenty of wildfire smoke and a few record-breaking heat days that served to remind us that summer wasn’t done yet. Here’s a quick and colorful graphical recap of our weather during August and how it relates to climatology.

NOTE: This monthly recap was delayed due to missing data in the August 2025 climate record for Boulder which has since been partially filled with best-guess approximations.
