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!
Shallow cold air has surged back into the Front Range overnight, causing temperatures to tumble and dense freezing fog to form. While the higher elevations enjoy sunshine and milder temperatures Saturday, the Plains remain in the 20s. An incoming storm system will bring light snowfall and reinforce the cold air Saturday evening, with the best chances of accumulating snow east of DIA and towards Kansas and Nebraska. We discuss just how cold it will be this weekend, the timing of the snow, and how much to expect. We also look ahead to our next and better chance of snow coming early in the upcoming week.
Northwest flow aloft will keep the start of 2025 cool and largely dry for the lower elevations. However, ridging aloft will allow for milder temperatures by the latter part of the week. The High Country will cash in on more snow Thursday and Saturday, perfect for skiers looking to start the New Year right. We also recap the brief high wind event that occurred on Monday.
Exactly three years to the day since a thousand Boulder County homes burned to the ground in the Marshall Fire, the Front Range is bracing for a similar yet tamer weather event on Monday, with high winds, elevated fire danger, and Mountain snow on the way. A quick-moving storm system will bring widespread gusts over 40 MPH to the area, creating conditions favorable for the spread of wildfires across most of drought-stricken northeast Colorado. While Monday is not expected to be as nearly bad as that fateful day three years ago, we urge you to remain vigilant to prevent any fire ignitions on Monday. We discuss the latest forecast, including how the developing conditions for Monday compare and contrast to those back in 2021.
Yesterday on Christmas Day, a deluge of rain dumped on the western Denver Metro area during the afternoon and evening, but amazingly not a single snowflake fell across most of the lower elevations as temperatures remained several degrees too warm for frozen precipitation. This led to the first “Rainy Christmas” that most of us have ever experienced. As expected, a white Christmas was enjoyed by those in the higher terrain where temperatures were colder. We recap the holiday raindrops and snowflakes, including a look at just how rare Christmas rain really is and if it will be the new normal in a warming climate.
