We hope you didn’t put your cold weather gear away for the season yet — another Arctic Blast will ooze into eastern Colorado this week! A strong Arctic high will entrench the region in bitter cold air through midweek, with highs during this period well below normal in the teens and 20s with lows in the single digits or slightly below zero. A few weather systems moving through in the westerly flow aloft will bring several chances for snow to the area, but for the most part accumulations will remain relatively light east of the Mountains. Temperatures will moderate by the end of the week and especially the weekend as ridging builds in from the west and the dense Arctic air retreats eastward with surprisingly warm weather not too far off on the horizon.

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.
Hot on the heels of an extremely warm and dry end to 2024, January landed on the complete opposite end of the spectrum with well above normal snowfall and very cold conditions across much of Colorado, including here in Boulder. Here’s a quick and colorful graphical recap of our weather during January and how it relates to climatology.

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.
