This week in Colorado weather: November 29, 2021

November 29, 2021 / Andy

The entire upcoming week will feature well above average temperatures across the Front Range with several days of record highs up for grabs. There will be a couple of “cool-downs” behind dry cold fronts but temperatures will still remain above seasonal normals on those days as well. While the upcoming week is expected to be totally dry, there are some hints of a return to a more active and unsettled pattern next week. We’ll discuss this and more in our weekly outlook so read on!

This week in Colorado weather: November 22, 2021

November 22, 2021 / Andy

Warm weather and sunshine will start out our holiday week as temperatures reach comfortably into the 60’s. A strong cold front will usher in much colder temperatures around midweek, along with a slight chance of snow. Early indications are that Thanksgiving will be seasonal and dry. A gradual warming trend is in-store for the latter half of the week and into the weekend with no major storm systems anywhere to be found in the pipeline.

The saga for our first measurable snowfall of the season is finally over, in Boulder at least. In a rather uninspiring fashion, the city reported its first official snowfall early Wednesday morning before sunrise. Let’s review how it happened, check in how this fits in with climatology, and congratulate the winners of our 2021 First Snow Contest!

October 2021 Weather Review: Drought returns after one of Boulder’s all-time driest Octobers

November 9, 2021 / BoulderCAST Team

October 2021 was extremely dry for all of eastern Colorado and drought has exploded once again across the region. Other notable highlights during the month include the return of La Niña for a second winter in a row, magnificent fall colors, a drizzly Halloween, and the lack of any accumulating snowfall yet in Boulder or Denver. Here’s a quick and colorful graphical recap of our weather during October and how it relates to climatology.

This week in Colorado weather: November 8, 2021

November 8, 2021 / Andy

After an unseasonably warm weekend across the Front Range, this week starts and ends with seasonal to below normal temperatures. A series of cold fronts will traverse through our area as a storm system strengthens over the midsection of the country. This pattern will favor snow for the higher terrain mid to late-week, but just dry, breezy, and chilly conditions for the Plains. Denver and Boulder are both rapidly approaching record territory for the latest first snow.

Our first snowfall of the season is running late, but that could change soon!

Happy Friday! It sure is gorgeous out there today. Change is coming however as the weather pattern is set to shift just in time for Halloween and the end of the month. We discuss the latest forecast surrounding the much cooler and gloomier weather about to settle into northeast Colorado…and yes, it will offer another chance for Front Range cities to pick up their first snow of the season!

La Niña is set to return for a second winter in a row, but what does this mean for Colorado?

For the second year in a row, La Niña conditions are expected to develop and last through the upcoming winter. We discuss the forecast, remind you what La Niña actually is, go over recent La Niña outcomes and explain the potential impacts this will have on Colorado for the rest of autumn.

With a chance of snowflakes in the forecast, here’s the entries to our 2021 First Snow Contest!

Thanks to everyone that entered our 2021 First Snow Contest. We briefly review the entries which actually trend towards an earlier date than Boulder’s climatology would suggest. That’s good news because snow may be in the forecast right now. Contest prizes and recognition will be awarded in the days following our first dumping of snow, BIG or SMALL!
