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.

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.
A warm, summer-like pattern is about to take over the Front Range in the middle of May. This week’s weather is driven by a robust mid‑level ridge anchored over the Desert Southwest, producing strong subsidence and a sustained warm anomaly across Colorado. A weak cold front on Tuesday will briefly cool us off, but its effect will be short-lived, with near-record heat building back in by midweek. Rain chances through the extended period remains quite low given the setup, but the late-week period is somewhat uncertain. We break down the dynamics driving this pattern and the implications it will have for the Denver–Boulder corridor through this warm, mostly dry stretch ahead.
April 2026 wrapped up as another water‑starved month along the Front Range, trading March’s record heat for a parade of fast‑moving systems that looked promising on paper but rarely delivered meaningful moisture. Temperatures still ran warmer than average overall, punctuated by a few sharp cold fronts that briefly returned a wintry feel before the pattern snapped back to mild, windy, and dry. Fire danger stayed elevated on many days, and despite several rounds of light precipitation, Colorado’s snowpack remained historically low heading into May. Let’s take a graphical look at how April unfolded across Boulder, Denver, and the Front Range — and how it stacked up against climatology.
This brief lull in the action Wednesday morning won’t last long as the pattern is set to turn unsettled again in a hurry. A pair of poorly aligned disturbances is gearing up to bring the Front Range a long‑overdue dose of moisture — along with snow in the higher terrain. While the bullseye of heaviest precipitation is frustratingly expected to be south of our area again, a slew of marginal ingredients are coming together for what should be our most meaningful storm in months. We break down what to expect as we head into a soggy, colder, and in some cases, snowier end to the week.
Colorado headlines have been buzzing about a looming “Super El Niño,” but the story behind the hype is far more layered than the headlines let on. Before leaning into the dramatic graphics and sweeping claims, it’s worth unpacking where this narrative actually came from and why one overzealous model run has taken on a life of its own. More importantly, we must consider what this all really means for our state as we limp into summer with record‑low snowpack, deepening drought, and a fire season that has already been sharpening its teeth. The truth is far more nuanced than the current online discourse suggests.
The atmosphere is gearing up for a dramatic mid‑week pivot, and the Front Range is about to feel every bit of it. We start the week under a warm, bone‑dry ridge that will send temperatures soaring and fire danger spiking—especially by Wednesday, when downslope winds and exceptional dryness are set to collide. But just as quickly, the pattern will flip. A pair of incoming troughs will drag us into a cooler, unsettled stretch of weather heading into the weekend, with several chances for much‑needed moisture and even the prospect of a few snowflakes mixing in at times. It’s a true tale of two patterns this week! Read on for all the details.
Friday delivered one of those classic Colorado curveballs. The storm showed up fashionably late, then hit harder than expected once it finally got going. It left behind a fast‑melting blanket of spring snow and cleared out almost as quickly as it arrived. In today’s update, we break down the wild midday burst of snow, take a look at how the forecast held up, and highlight why the real headline may have been what happened — or didn’t happen — after the flakes stopped.
