This week brings a stretch of unseasonably warm and quiet mid-November weather across the Front Range, with highs holding in the upper 60s to low 70s through Friday. However, a stronger cold front arrives in time for the weekend and it could finally deliver a shot of snow. Models remain split on the system’s track, leaving the Metro area with only modest odds to see accumulating snow, while the Mountains look primed for several inches. With records for Boulder’s latest first snowfall and longest snow‑free streak hanging in the balance, this is a setup worth watching as the week unfolds.
Bundle up and brace for an eventful week of fall weather across the Front Range as temperatures turn colder! Gusty winds and even a few thundershowers on Monday will precede a frontal boundary set to bring the season’s coldest air yet. Read on for all the details of the week ahead, including a discussion of nightly hard freezes, the Halloween forecast, and a weekend warm-up that might just make you forget it’s the start of November…
Clouds roll in Thursday as a compact storm system approaches from the southwest—but don’t expect much more than a few sprinkles and high mountain snow. Boulder and Denver stay mostly dry, with mild temps in the 60s and a sunnier stretch ahead for Friday and Saturday. A stronger trough will arrive Sunday into early next week, bringing gusty winds and a taste of cooler fall air, but once again little in the way of meaningful rain or snow east of the Mountains. Read on for all the details.
This week’s forecast is anything but boring in the Front Range. A fast-moving autumn storm is stirring up the atmosphere on Monday with jet-driven Mountain snow, powerful downslope winds, and a fire-weather setup that demands caution. And once the winds die down? A hard freeze will slam the door on the growing season for the entire area Monday night. Read on for a full breakdown of the very active weather unfolding in Colorado on Monday, plus a peek towards the quieter days ahead.
August 2025 was on track to be our third scorcher in a row — hot, dry, and smoky — until a late-month shift brought in a welcome stretch of cooler, wetter weather. That pattern change helped balance things out across the Front Range, with most areas landing close to average for rainfall and just slightly warmer than normal overall. Still, it wasn’t all relief: the month packed in plenty of wildfire smoke and a few record-breaking heat days that served to remind us that summer wasn’t done yet. Here’s a quick and colorful graphical recap of our weather during August and how it relates to climatology.
NOTE: This monthly recap was delayed due to missing data in the August 2025 climate record for Boulder which has since been partially filled with best-guess approximations.
Last week’s cold front didn’t just drop temperatures—it dragged in a wall of chemical-scented smoke that turned the Front Range skies hazy and acrid. The days ahead are shaping up to be much more pleasant with warmer temps, limited storm chances, and a break from the smoke (at least for now) under southwest flow. Read on for a full breakdown of this week’s weather, including when to expect the best shot at rain and whether any smoke may return in the extended.
September kicks off with a mellow vibe across the Front Range — warm days and mostly dry skies are expected. But don’t let the quiet start fool you. Between drifting wildfire smoke, sneaky cold fronts, and a potential tropical system by the weekend, there’s more nuance in our forecast this week than meets the eye. Read on as we break down what to expect day by day, plus what might shake things up by the weekend.
