Following a bitter cold and snowy January in the Front Range, the month of February so far has brought with it milder conditions. Last week we had our first 60-degree day in Boulder since just before Christmas, and even our first 70-degree day since late October. The warmer weather has been a welcomed reprieve, though it has rightfully confused some flowering plants across the area with early blooms. This warm weather was never going to last though — we’ve still got plenty of winter to go and this week will get us right back on-track with a two-part blast of Arctic air and snow headed for the Front Range. Read on for the latest details on the snowfall timing, amounts, and expected temperatures.

While Punxsutawney Phil and Flatiron Freddy both saw their shadows Sunday morning solidifying their predictions for six more weeks of winter, we’ll start off February with wildly above normal temperatures in the 60s to lower 70s here in the Front Range. However, we are watching an Arctic cold front that will peskily waver back and forth across northeast Colorado as the week progresses leading to fluctuating temperatures and plenty of uncertainty. The brunt of the cold air, though, likely will not plunge into our area until sometime next week alongside increasing chances for snowflakes.
After a definitively wet November in the Front Range, Mother Nature did a complete one-eighty with December landing one of the warmest and least snowy on record in many locations, topped off with our first rainy Christmas in 82 years! Here’s a quick and colorful graphical recap of our weather during December and how it relates to climatology.
2025 has been exceptionally cold and snowy in the Front Range so far, but is that finally about to change? This week we can expect several tranquil sunny days to begin but we are watching the threat for more snow as a low-pressure system approaches from California by Thursday.
We haven’t really seen much melting of the more than a foot of snow that fell last weekend in Boulder, but additional white stuff is indeed on the way this weekend! A slow-moving storm system will bring relatively light but long-lasting snow to the area Friday night into Saturday night, with a heavy focus on the northern Front Range this time (Boulder and Larimer Counties). Some locations could see upwards of a foot of snow as temperatures plummet back into the teens for Saturday. Let’s take a look!
As of Sunday afternoon, skies are sunny and Round #1 of our Arctic Blast is in the books. This wave, which was always more about the white stuff than the extreme chill, delivered several fluffy inches of snow to the entire area, even over a foot in parts of Boulder County. Despite how nice it looks outside now, we are closely tracking Round #2 arriving Sunday evening into Monday with even colder air and another pulse of fluffy snowfall. Let’s take a look.
