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.
