Why do mountaintops stay snowy, even though they’re closer to the Sun? The answer has to do with the air we breathe and that bright white snowpack, as an atmospheric scientist in Colorado explains.

Snow-covered mountain peaks reflect the Sun's rays back toward space instead of absorbing them, which helps maintain those freezing temperatures even on bright, sunny days, explains a climatologist.

Drought continues to expand in Colorado, with this week's US Drought Monitor showing a new area of extreme drought (D3) around the Denver metro area and expansion of severe drought (D2) in northeast Colorado, in addition to the ongoing extreme to exceptional drought in the mountains. #cowx

The West’s Winter Has Been a Slow-Moving Catastrophe Without snow in the mountains, the places that depend on the West’s rivers will hurt for water.

The snow this week has been very welcome, but we’re still way behind for the winter. Coverage of the implications of low mountain snowpack in The Atlantic:

Colorado has its lowest snowpack on record, but official records date back only to 1987.

It's likely that snowpack was actually worse in both the 1976-77 and 1980-81 winters, per analysis from @climate.colostate.edu's @rschumacher.cloud.

Great insight here:

The mountain snowpack so far this winter is in bad shape. Long-time Coloradans might remember two other terrible winters for snow: 1976-77 and 1980-81. Our latest blog post takes a look at how this year compares to those snow droughts of the past. #cowx

Series of big storms needed to make up huge snow supply gap, Colorado water experts say There’s still winter left, but Colorado experts say the state needs some mega snowstorms to reach an average snowpack and water supply.

β€œWe’re far enough into the winter that it starts to become difficult to dig out of these deficits,” (Assistant State Climatologist Peter) Goble said. β€œIt’d take a big year to get us back to normal”

The first half of meteorological winter was record warm for an extraordinary swath of the West, from Las Vegas to Denver, Salt Lake City to Seattle and Phoenix to Portland. The anomalously temperatures are fueling a snow drought, concerning scientists.

It hasn't been cold this December, but 3 years ago it got cold in a hurry. Do you remember the cold front on December 21, 2022? It was extreme in all kinds of ways, which you can read about in this blog post.

Among the highlights: the temperature dropped almost 25Β°F in ten seconds in Akron! #cowx

Wildfires can spread quickly β€” by the time one is nearby, you may not have much time. Have an evacuation plan, and prepare an emergency supply kit ahead of time. Listen to local officials for emergency information and any evacuation orders.
