January 8, 2024 / Andy

Breezy conditions and chilly temperatures will kick off the week behind a departing winter storm which brought a thin blanket of snow to the Metro area last night. Highs below freezing on Monday will trend slightly warmer in the coming days, but with gusty winds remaining. The tail-end of the week will turn more active with a few chances at light snowfall. There are also signs in the extended that an Arctic airmass will ooze into the region during the upcoming weekend turning things even colder for us. Read on for more details

December 2023 was yet another warm month in Boulder, the same fate which has befallen four out of the last five months. Despite the lack of appreciable snow events, precipitation ended just a hair above normal for the month since December is typically one of our driest months of the year.

Winter Weather Update: First southern-track storm (of several) turns things much colder on Thursday, but snowflakes will be hard to come by

The weather pattern is shifting as we speak across the West and with several southern-track storms set to impact our area in the coming week or so. The first arrives on Thursday, but unfortunately it is coming in a bit too far south with things largely bypassing the Denver Metro area. Still there will be some amount of wintry weather to end the week. Let’s take a look at the latest forecast for not only the storm knocking on the door, but the next one gearing up for late in the weekend.

El Niño has yet to deliver any major storms to the Front Range this winter season but that could change heading into the first week or two of January as a more active southern storm track takes shape across western North America. Several systems will bring snow to Colorado, though the focus appears to be across the southern tier of the state rather than the Front Range.

This Week in Colorado Weather: December 25, 2023

December 25, 2023 / Andy

The Christmas holiday week starts off on the cold to chilly side as an area of low pressure continues to impact us from the central United States. There will be another chance of snow late tonight on Christmas into Tuesday, but only light accumulations are expected south and southeast of Denver. However, blizzard conditions are set to unfold across far eastern Colorado with travel eastward becoming impossible at times Monday night into Wednesday. A trend towards drier and warmer weather is in-store for the latter part of the week and to close out 2023. Read on for the latest details.

Holiday Snow Update: Rain transitions to snow Saturday evening, most accumulation over by Christmas Eve morning

December 23, 2023 / BoulderCAST Team

Winter weather is on-track to arrive into the Front Range Saturday evening into Sunday just in time to give most of us a white Christmas! Two vastly different storm systems will be moving in from opposite directions later in the day Saturday with widespread rain changing to snow across the Boulder and Denver area. While we still have some lingering concerns regarding temperatures and exactly when rain will switch-over to snow, our forecast confidence has grown over the last few days. In this final forecast update, we discuss the storm’s timeline, how much snow will accumulate across the area, the probability the snow sticks around into Christmas Day, and how it will impact holiday travel the next few days. We’ve even got another chance of snow coming the day after Christmas. Whew! Read on for all the details.
