This Week in Colorado Weather: January 26, 2026

A fleeting brush with winter may have swept across the Front Range this past weekend, but the atmosphere isn’t planning to stick with the theme for long. That sharp Arctic plunge—while refreshing for snow lovers—was more of a brief interruption than a true turning point. A closer look at the pattern ahead shows Colorado snapping right back into its now‑familiar routine of warm afternoons, bone‑dry air, and a statewide snowpack sitting at record‑low levels. Winter may have knocked on the door, but it certainly isn’t moving in.

Premium BoulderCAST Daily – Wed 01/21/26 | One last mild day before temperatures really begin to tumble

Last night’s weak cold front was just the beginning of what’s shaping up to be a full‑blown temperature slide straight into the weekend. Over the next couple of days, three more fronts will spill south out of central Canada, each one tugging progressively colder air into eastern Colorado, with a true Arctic punch arriving Thursday evening. For today, though, we …

Premium BoulderCAST Daily – Tue 01/20/26 | The warmest day of the week comes with elevated fire danger, bitter cold and light snow still brewing for late-week

Today stands out as the warmest day of the week, largely because it’s the only one not immediately trailing a cold front. Enjoy it while it lasts. With abundant sunshine and a relatively undisturbed airmass overhead, temperatures will climb comfortably into the lower 50s in Boulder and the rest of the lower elevations.

Premium BoulderCAST Daily – Fri 01/16/26 | High wind event gives northeast Colorado a rare day with critical fire danger AND cold temperatures–stay weather aware!

The latest temperature‑timeline graph out of Boulder tells the story loud and clear: last night’s cold front didn’t just arrive—it punched its way through around 8:30 PM, dropping temperatures nearly 20 degrees in just minutes. A true “blink and suddenly you need a jacket” kind of front. In the wake of that abrupt boundary, today is shaping up to be …

Premium BoulderCAST Daily – Wed 01/14/26 | A gorgeous Wednesday ahead of increasing fire danger & a stronger cold front tomorrow

Last night’s weak cold front slipped through right around 9:30 PM—it was nothing crazy, just a subtle dip in temperatures, a bump in dew points, and a shift of the winds around to the northeast direction. As expected, a few light rain showers are hanging out east of Denver this morning. They’re already looking pretty flimsy on radar and aren’t …

Premium BoulderCAST Daily – Tue 01/13/26 | A thick blanket of high clouds won’t stop us from reaching the 60s again

Moisture is streaming overhead this morning like a quiet conveyor belt, and it’s doing a fine job painting a broad shield of mid‑ and upper‑level clouds across all of Colorado. GOES‑East imagery shows the whole thing unfolding in real time—an impressive, almost uninterrupted swath of clouds stretching in from upstream. The infrared channels are lighting up thanks to those bright, …

This Week in Colorado Weather: January 12, 2026

A stubborn weather pattern is settling in this week, and Colorado finds itself right in the middle of the action—or the lack of it. While the coasts deal with weather extremes, the Front Range gets a quieter blend of mild spells, a couple of cold fronts, and just enough uncertainty to keep things interesting. Read on for our full outlook of the next seven days to see if this translates into meaningful moisture or just more dry January days.
