February 17, 2024 / BoulderCAST Team

Well, most of us are waking up and having to shovel snow for the third Saturday in a row! This tiny recap post covers our latest winter storm, including a map of the verified snowfall totals and where we stand season-to-date against climatology.

This Week in Colorado Weather: February 12, 2024

February 12, 2024 / Ben Castellani

After our second snowy weekend in a row, things will stay quiet across the Front Range for much of the upcoming week with seasonal temperatures and lots of sunshine. However, that will change late-week as a quick-hitting Arctic cold front will surge south across the area. This front will likely be accompanied by at least a little bit of wintry precipitation, but the cold won’t stick around long at all. We also look ahead to several more devastating atmospheric river events set to slam California — their remnant moisture will likely spread into our Mountains to further bolster statewide snowpack. Read on for all the details.

Winter Weather Update: Two-part winter storm brings snow for a second weekend in a row, locally heavy snow expected at times

February 9, 2024 / Ben Castellani

After a largely quiet work-week with seasonal temperatures and dry conditions across most of the Front Range, winter weather will make a return for the second weekend in a row! A series of disturbances will impact Colorado over the next couple days seeding the return of snow to the area. Winter weather will come in two parts — the first Friday night with locally heavy convective snowfall expected. A second wave of more widespread, but lighter snow will develop Saturday behind a weak cold front. Let’s take a look at the latest forecast for Super Bowl weekend, including our expected snowfall totals and the timing of the worst travel conditions.

January 2024 Graphical Weather Review: One of our coldest starts to a calendar year!

February 6, 2024 / BoulderCAST Team

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.

Winter Storm Recap: The system that buried the Front Range in cement was Boulder’s wettest February storm on record

February 5, 2024 / BoulderCAST Team

Well, our snowfall forecast for the sloppy weekend storm ended up being a tad off in many areas. Hopefully our in-depth discussions in the days leading up to the event highlighted that the exact outcome of this warmer-than-usual storm was highly uncertain. We first review the record-breaking precipitation and snowfall totals across the Front Range. Then we discuss what went wrong with the forecast and dive into the finer details of this implausible moisture-infused winter storm.

Winter Weather Update: A warm El Niño storm is headed our way this weekend with snow amounts remaining somewhat uncertain

February 2, 2024 / BoulderCAST Team

After five straight sixty-degree days with quiet weather, things will turn cooler and unsettled for the weekend ahead as a sloppy El Niño storm moves through bringing a mix bag of precipitation to the Front Range. While there is still plenty of uncertainty in the exact outcome for Boulder and Denver, we discuss the latest forecast details including when the rain will start (including some rumbles of thunder), when and where it will change over to snow, which ski resorts will be rolling in powder this weekend, and most importantly — the expected moisture and snowfall amounts across the Front Range area. Let’s dive in!

This Week in Colorado Weather: January 29, 2024

January 29, 2024 / Ben Castellani

We got our first taste of 60-degrees in the New Year on Sunday and those sixties will continue through much of the week ahead as high pressure dominates our weather. However, as you’ve probably heard already, a potent Pacific storm is looming in the extended with a slew of impacts expected across the Front Range during the upcoming weekend. Uncertainty is unsurprisingly quite high being six days out, but early indication does show a good chance for a significant accumulation of heavy wet snow in the Metro area following a period of rain. Read on as we discuss not only the beautifully warm and sunny weather this week, but also the cold and snowy stuff brewing for the weekend.
