A Soaker or a Near‑Miss: Will Hurricane Polo’s Remnants Push Far Enough North to Drench Denver and Boulder? (Updated)

September 29, 2026 / / 0 Comments

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.

This Week in Colorado Weather: September 28, 2026

September 28, 2026 / / 0 Comments

A complicated weather pattern is taking shape across Colorado this week, with a deep low pressure system, a surge of tropical moisture, and the remnants of Hurricane Polo all getting tangled up together. For Boulder, Denver and the Front Range, that combination creates some unusually large forecast uncertainties — particularly when it comes to how much rain falls and just how chilly things get by midweek. Meanwhile, southern Colorado is in store for a much bigger soaking, with some impressive rainfall totals showing up in the guidance alongside high peak snowfall. We break down what we know now, what remains uncertain, and when we can finally expect this week’s definitively gloomy weather to break and sunshine to return.

Colorado Forecast Update: Thursday Gloom, a Beautiful Weekend and Some Big, Wet Questions for Next Week

September 24, 2026 / / 0 Comments

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.

May 2026 Graphical Weather Review: A Tale of Two Storms — Damaging Snow and a Deluge of Rain Put a Dent in the Drought

June 4, 2026 /

May 2026 delivered a true roller‑coaster pattern along the Front Range. Despite finishing warmer than average, the month was punctuated by two significant chilly precipitation events that funneled a remarkable amount of moisture into Boulder and Larimer Counties. The first arrived as a damaging late‑season snowstorm, wrecking leafed‑out trees across the region, while the second system — fortunately — remained all rain at lower elevations.

Together, these systems provided meaningful drought relief, though the broader hydrological picture across Colorado and the West remains deeply strained. Here’s a graphical look at how May unfolded across Boulder, Denver, and the Front Range — and how it compared to climatology.

Colorado Drought Update: Boulder Just Matched Its Last 7 Months of Precipitation — In Two Weeks

May 22, 2026 /

May has finally snapped the atmosphere out of its months‑long bone dry spell, and the Front Range is making up for lost time fast. A destructive early‑May snow event, followed by a second, well‑timed upslope system just ten days later, has pushed Boulder’s May precipitation total beyond everything we managed to scrape together through fall, winter, and early spring combined. We dig into what triggered the pattern reversal, how much moisture different parts of the region have banked, what this burst of wet weather actually means for our entrenched drought, and whether the upcoming Memorial Day weekend warm‑up signals a slide back toward a more aggressive drying trend.

This Week in Colorado Weather: May 19, 2026

May 19, 2026 /

After a devastating spring snowstorm barely more than a week ago, a slow‑moving May storm parked itself over the northern Front Range, wringing out 1–2 inches of moisture and dropping a fresh blanket of wet snow in the Foothills — all without giving the lower elevations any freezing temperatures. For mid‑May, that’s about as friendly as a storm of this size gets. And with the larger‑scale trough refusing to budge, we’re not done yet: this week will feature more daily shower chances through Friday before drier, warmer weather returns just in time for the holiday weekend. Read on for all the details.

*Premium* Storm Update – Mon 05/18/26 8:00AM | Rain and higher elevation snow ramp up through the day, freezing temperatures unlikely tonight

May 18, 2026 /

A fresh surge of moisture, lift and colder air are flowing into the Front Range today, with rain, high‑elevation snow, and even a few rumbles of thunder unfolding before the storm finally winds down Monday evening. The highest terrain could quietly overachieve on snow, while the Boulder-Denver area stays mostly just rainy. We also check in on the declining chance for sub-freezing temperatures Monday night.

Colorado Forecast Update: Another soaking storm is headed for the Front Range. Fortunately it’ll be too warm for (much) lower elevation snow this time

May 17, 2026 /

That quiet Sunday morning was lovely wasn’t it? But the sun is unfortunately gone as as powerful spring storm is digging into the West, already lighting up hazard maps from California to Montana to Kansas with snow, fire and wind warnings. For the Front Range, the approaching system will provide another round of widespread, soaking precipitation with the target once again on Boulder and Larimer Counties.

After a round of scattered showers and storms during the day Sunday, including some severe ones east of Denver, a more widespread precipitation shield will develop overnight and continue into Monday, with the Foothills grabbing accumulating snow and the lower elevations flirting with a few wet flakes as well. We break down the timing of everything, the most likely precipitation and snowfall totals, the post-storm freeze risk, and what this storm means for our ongoing drought.
