The beginning of 2024 was completely opposite to the conclusion of 2023, with temperatures taking a sharp colder turn as multiple Arctic outbreaks slammed the Front Range. Warmer temperatures toward the end of the month saved January from being one of the all-time coldest here. There were also several light snow events during the month, but nothing substantial — not surprising as January is our driest month of the year after all. Here’s a quick and colorful graphical recap of our weather during January and how it relates to climatology.

No updates to the going snowfall forecast. Still expecting a cold, gloomy and mostly dry day. Best chance of seeing snowflakes is this evening SE and E of Denver. Maybe a few more Friday PM.

Both #Boulder & #Denver are now under a Winter Weather Advisory late Sunday night into Monday afternoon. Probably going to be some disappointed folks in eastern Boulder County. Nonetheless, most of us will awake Monday to a wind swept dusting to 3" of snow (highest south)! #COwx pic.twitter.com/f31fGMboV6

6:30AM Update: Overnight snowfall was mostly light & fluffy, but wind chills are now close to ZERO. Roads are slick & snowy across the entire area with a dusting to 3" on the ground. Snow, some heavy, continues south of Interstate 70 this morning. Drive safe! 🚗💥 #Cowx pic.twitter.com/Jq1ogPHJHB

❄️ Official snowfall totals from the "holiday weekend in the Arctic" were 7.1" in Boulder and 3.0" in Denver, split across two (arguably three) unique snowfall events. Totals of 2 to 5 feet were common in the Mountains!

This is somewhat of a cherry-picked statistic, but nonetheless the period of Saturday to Tuesday has tied for the 4th longest streak in #Boulder history for number of consecutive days where -7°F (or colder) was reached! #COwx #Boulderwx pic.twitter.com/IFpIulQz3C

It's been 38 days, but we finally reaches 60 degrees again this afternoon in #Boulder. This is just the first of many 60+ days to come this week before a big ol' wet & snowy storm hits during the upcoming weekend. Happy Sunday! 🏔️ 🌞 #cowx pic.twitter.com/vzQlgIO6yF

The “flatness” of the Snow Probabilities is as clear of a sign as any that the models aren’t quite sure how to handle this system yet. The Denver area currently has an equal chance of seeing <1″ of snow as seeing 12"+ (~25% chance of each)! https://t.co/uQNnjZewE8 #COwx pic.twitter.com/IrwA5Y672i
