April 15, 2020 / Ben Castellani

Boulder picked up nearly 19″ of snow from the cluster of storms earlier this week and now has a very good chance of breaking its century-old seasonal snowfall record. We discuss why Boulder has seen so much more than Denver this snow season, and also comment on our next winter storm knocking on the door Wednesday night into Thursday.

With the conclusion of last night’s quick-hitting snow event, our fourth in just the last eight days, Boulder has now officially eclipsed the typical amount of snow that falls in an entire season, and we’re not even half way through the month of February!

November 14, 2019 / Ben Castellani

From record warmth over the weekend, to snow and bitter cold on Veterans Day, to the rebound back into the 60’s just one day later…it’s been quite a wild week in Colorado weather.

Where did this week’s Arctic airmass come from? Why the Arctic, of course!

November 1, 2019 / Ben Castellani

Using a technique called reverse trajectory analysis, we step back in time to see where the bitter cold air this week originated from. We also explain why we believe the odds of another Arctic intrusion into the United States are elevated during the coming week.
