Last night’s quick-hitting snowstorm hit with a bang in the southwest Denver Metro area and southern Foothills, with locally heavy snowfall up to 20″ falling in parts of Jefferson County. Elsewhere, snow amounts fell well in-line with our forecast, including some Front Range cities not receiving a single snowflake! We review how the storm unfolded, the snow totals from across the region and look ahead to the remarkably warm and sunny weather about to take center stage.
A several hour period of banded snowfall impacted the entire Front Range during the daytime hours on Saturday as a weak system, with embedded jet energy, moved across the area from the northwest. We briefly review both the snow totals from this single storm and the seasonal ones.
Our second Arctic Blast of 2025 is already underway! The first round of bitter cold has already gripped the Front Range, with light snow falling last night and temperatures plunging into single digits this morning. However, the worst is yet to come! Another wave of Arctic air is set to sweep through later on Tuesday, bringing several inches of snowfall and eventually sub-zero temperatures to the entire area. We discuss the latest forecast details, including when this next round of snow will begin and end, expected snowfall amounts across the area, and just how cold it will get in the days ahead.
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.

Here’s a quick and colorful graphical recap of our weather during December and how it relates to climatology.
