This Week in Colorado Weather: February 3, 2025

February 3, 2025 / Andy

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.

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.
