The pattern is gradually shifting across Colorado, with lingering moisture keeping Thursday cool and cloudy before drier, warmer weather settles in for the weekend. Beyond that, the forecast becomes much less certain as the first significant autumn trough approaches from the west and potentially interacts with the remnants of Hurricane Polo across the southern Rockies. There are several possible outcomes for early next week in the Front Range, ranging from a quick cooldown with some showers to a much wetter setup. We break down what the models are showing, what we’re confident in, and what remains uncertain.

Despite an active monsoon that refuses to quit, Boulder has remained stubbornly dry with just 18% of normal precipitation during September which has been anything but typical. This week will keep the theme alive: plenty of monsoon flow, impressive moisture surges, and even a pair of dancing hurricanes in the Eastern Pacific, yet northern Colorado will still struggle to squeeze out meaningful rainfall again. We break down why the pattern looks so active on paper, why the Front Range keeps missing out, and what late‑week changes might finally nudge storm chances upward.
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.
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.
