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.
The first major Arctic blast of the season is set to arrive Friday afternoon, bringing a dramatic drop in temperatures and widespread snowfall to Boulder and the Front Range. Expect temperatures to plummet from the 60s on Thursday to the single digits by Saturday morning, with several inches of fluffy snow blanketing the area. The bitter cold will linger through Tuesday, with temperatures below freezing for nearly 100 hours and below 15°F for around 72 hours. Read on for the latest details on what will definitely be a frigid and snowy MLK Day weekend across most of Colorado!
This week will feature a mixture of calm and chaos in Front Range Colorado! While the early part of the week will be relatively quiet with cool temperatures, a significant change in our weather is brewing for Friday. An Arctic blast is set to slam eastern Colorado during the late-day period, ushering in the coldest air of the season this weekend alongside widespread snowfall. Enjoy the sunshine and mild conditions the next several days, but begin preparations for the deep freeze and snowy conditions ahead!
