It’s not every day that you get to head south to Antarctica. CSU student Chelsea Bekemeier had the privilege of doing just that for her master’s research, visiting one of the most remote places on Earth: Denman Glacier — a massive glacier that fills a canyon reaching 3,500 meters below sea level.

A bolide exploded high above New England in Earth's atmosphere on Saturday afternoon, creating a loud booming noise that was heard across the region. The flash of the exploding meteor was detected from the GOES-19 weather satellite's GLM instrument.

Severe thunderstorm activity will be ramping up in eastern Colorado this weekend, right on time in mid-May. Here’s a blog post from a couple years ago with the where and when of Colorado severe weather, along with where to get timely information. #cowx

Polar-orbiting satellites captured snow on the ground in Wyoming and Colorado from this week's May snowstorm. This animation shows the ground snow being visible both during the day and night.

A perspective piece I wrote for @ametsoc.org on National Meteorologists Day and why it's needed... headlines.ametsoc.org/2026/05/08/i...

9 years ago today, the costliest hailstorm in U.S. and Colorado history pummeled the west side of the Denver metro area. An estimated 150k auto insurance claims came in after baseball-size hail blasted Wheat Ridge, Arvada, and Lakewood. It destroyed the Colorado Mills mall. What do you remember?

March 2026 rewrote the record books for early-spring warmth in Colorado. It was warmer than most Aprils. Hundreds of temperature records were set across the state, including a new March record of 99°F. The heat was prolonged, and it was also very dry. Read more in our monthly state climate summary.👇

This is my new favorite graphic produced by @climate.colostate.edu and @rschumacher.cloud. It's also been quite fascinating to watch the accumulation of above average temperatures for the water year. Find it here: climate.colostate.edu/co_cag/

Learn from @climate.colostate.edu's Allie Mazurek about why mountains stay snowy ⬇️ theconversation.com/why-do-mount...

“Colorado has warmed at a faster rate than the global average and is expected to continue to warm...Having said that, not every winter going forward is going to be as warm as this winter. And, in fact...I think this winter will be considered a much-warmer-than-normal winter for some time to come.”

"We look ahead to March & April as the time when big storms are possible and the deficits can be made up. Unfortunately, this year has been just the opposite: Instead of much-needed snowstorms, we’re in an unprecedented March heat wave that is accelerating the melting of what little snow is there."

The March summary for the Fort Collins weather station that our office maintains is chock-full of eye-popping stats. Highest single-month temperature anomaly in the 130+ year period of record, 8 days warmer than the previous March record, earliest 90° day on record by over a month, and more. #cowx

Last week’s heat wave was record-smashing, extraordinary, and impossible to ignore. It continued yesterday and even today in parts of the state. This new blog post provides some climate context on the mind-boggling temperatures and how they are affecting the drought and snowpack situation. #cowx

Take a two-day glimpse into the dynamic atmosphere above the Eastern Pacific Ocean.

A bitterly cold second half to the month of January saw an extensive growth of ice over the Great Lakes, with over half of the surface area across the five lakes covered in ice. Lake Erie, the shallowest of the Great Lakes, has over 95% of its surface area covered in ice.
