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. As Hurricane Marie drifts offshore of Baja California, pulses of subtropical moisture will begin sneaking into the state, boosting storm chances in the High Country and adding some intrigue to an otherwise familiar stretch of warm, southwest flow. 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.

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.
The atmosphere is gearing up for a busy stretch in Colorado, and this week’s forecast has a little bit of everything: a juicy monsoon plume to start, a sharp mid‑week dry‑out, and eventually a deep moisture surge tied to a tropical cyclone that could push the state’s moisture levels into rare territory. Whether that translates into meaningful rainfall east of the Continental Divide is the big question — and the answer hinges on timing, storm motion, and whether we can sneak in a well‑placed cold front or two. There’s plenty to watch this week for the Front Range. Let’s dig into the details.
A stubborn late‑summer pattern is locked in across the Front Range this week. While it won’t bring major shifts, it will deliver subtle day‑to‑day changes worth watching. A strong subtropical ridge keeps monsoonal moisture just high enough for daily storm chances, yet still too disorganized to produce reliable rainfall — a theme all summer. With shifting flow aloft, a mid‑week cold front and moisture bump, and a gradual drying trend late in the week, there’s plenty to unpack, from renewed severe potential to evolving flash‑flood risks and ongoing drought concerns. Read on as we break down the key ingredients driving this persistent — and likely still underperforming — monsoon pattern.
A series of subtle weather shifts will shape the upcoming week along the Front Range, beginning with a return to warmer temperatures and a brief interruption of monsoonal moisture. A midweek frontal passage then reintroduces instability, moisture transport, and an uptick in storm coverage — including the potential for some severe cells. Heat will rebuild late week as the ridge re-strengthens over the area, before another likely resurgence of monsoonal flow enters the discussion for next week. Read on for all the details.
After weeks of sizzling heat and hydrological disappointment, a deep surge of monsoon moisture is pushing into the Front Range today, with precipitable water values approaching 200% of normal and a highly efficient rainfall environment already in place. Satellite imagery and overnight boundary interactions are signaling an active convective day ahead, with both severe and flooding hazards on the table Thursday. Monsoon storm chances will progressively decrease but ultimately stick around through the weekend alongside below normal temperatures. We dive into the forecast specifics, including the monsoon moisture transport, mesoscale boundaries, severe and flood risk, expected rainfall amounts, and how the weekend will play out as subtropical moisture slowly retreats.
As we kick off the week, the Front Range is staring down a few more days of stubborn August heat — but that pattern is about to crack. A midweek shift will pull cooler air, deeper monsoon moisture, and widespread storms back into Colorado, including a real shot at heavy rainfall. After weeks of haze, heat, and bone‑dry afternoons, the atmosphere finally looks ready to turn the page. We break down what this transition means for the Boulder-Denver area, and how long the cooler, wetter pattern is poised to stick around.
