Last week’s storm finally delivered the kind of soaking rain we’ve been waiting months to see, but don’t get used to it. The atmosphere is shifting back into a familiar pattern this week, with summer-like warmth, abundant sunshine, and another surge of tropical moisture headed toward the Southwest. The catch? Most of that moisture will never make it to the Front Range. In this week’s update, we look at the drought-improving impacts of last week’s storm, why the San Juans are poised to cash in yet again, and whether a late-week cold front can squeeze out a little bit of rain for us before temperatures finally start feeling a bit more like October.

After months of drought, the Front Range is finally cashing in on a meaningful storm, with Boulder already topping an inch of rain and more moisture still to come. But are the best rains already behind us? A closer look at the storm’s evolving track suggests the answer may be yes, while a hard freeze waits on the other side of this long-overdue autumn gloom.
After months of watching drought deepen across the Front Range, Colorado is finally getting a storm that could turn the tide. A slow-moving upper low will tap into an unusually rich plume of subtropical moisture and bring widespread rain to much of northern Colorado, along with the season’s first meaningful Mountain snowfall. How much rain can Boulder and Denver expect, who stands the best chance of topping an inch, how low will snow levels drop during the event and which night will bring the season’s first freeze? We break down the latest forecast, timing, rainfall totals, and snow prospects.
After one final taste of summer warmth on Monday, the weather pattern across Colorado is about to undergo a dramatic shift. A much colder and wetter setup is taking aim at the Front Range this week, with rain returning to the forecast, accumulating snow in the Mountains, and perhaps our first real frost threat of the season by week’s end. While we’ve seen promising storm systems fizzle already this fall, the data continues to suggest this one has a better chance of delivering. We break down the timing of the cooldown, what the latest ensemble guidance says about rainfall totals, and why Friday and Saturday mornings will bear watching for frost.
Boulder just endured its driest water year on record, closing out twelve months with only 10.65 inches of precipitation — barely half of normal and nearly at desert-level. From a failed snow season to record spring warmth and a monsoon that largely bypassed the city, every season conspired to keep Boulder locked in a warm‑and‑dry feedback loop. Reservoirs and upstream snow storage will cushion the blow for now, but the bigger question looms: what happens if we start stringing years like this together?
A broad, slow‑moving heat dome has settled over the West, delivering a run of persistent October warmth to the Front Range — but this quiet, summerlike stretch won’t hold forever. This week will be defined by record‑challenging heat aided by downslope flow, and only the faintest chances for a few stray rain showers before a major pattern shake‑up arrives early next week. Ensemble guidance hints at everything from long‑awaited rainfall to the season’s first frost, with even a few early‑season snow scenarios lurking in the spread. Read on for all the details.
A slow‑moving, high‑stakes storm has been creeping toward Colorado all week — a rare mash‑up of an autumn upper‑low and the juicy tropical remnants of Hurricane Polo — and for a moment, it looked like Boulder and Denver might finally score a true soaking. But as the atmosphere loves to do, the script flipped late. Today’s update breaks down how this once‑promising setup unraveled over the last couple days, why southern Colorado is now squarely in the bullseye, and what scraps of moisture the Front Range can still squeeze out as the system passes by to our south.
A slow‑building, tropical‑charged system is about to make its move on Colorado — and the setup behind it is far more complex than your typical late‑September storm. As Hurricane Polo’s remnants collide with a impressive Pacific upper‑low, the stage is set for a rare, moisture‑laden system that could deliver anything from a major rain event to a near‑miss for Boulder and Denver. We break down why the models are struggling, what the key track differences mean for your neighborhood, and where flooding and high‑elevation snow may become real concerns as the storm unfolds.
UPDATED Tuesday Sep 26 5:00PM: Updated rainfall forecast map and some wording to account for growing confidence the bulk of the storm will miss the Denver Metro area.
