Yesterday was the wettest day in quite some time for northeastern Colorado. Widespread observations of over 1" of rain, and over 2" in some spots on the Plains. Several inches of snow in the mountains too! Map from coagmet.colostate.edu #cowx

It's that time of year for green and gold 💚💛

Tsukada's work builds on CSU Department of Atmospheric Science Professor Emeritus Wayne Schubert‘s previous work. “My study is positioned as an observational validation of the tropical cyclone dynamics that Wayne’s group investigated theoretically and numerically from 1999.”

“The biggest factor is the dry spring conditions and layered on top of them a much drier than normal summer,” said Peter Goble, assistant state climatologist. “We will be watching those base flows but also soil moisture levels as we go into fall and early winter to see if those pick back up.” #cowx

Typhoon Podul crosses southern Taiwan bringing heavy rain and strong wind. Podul is expected to make landfall in China later today.

July seems like a long time ago, with everything happening with drought and wildfire in Colorado in the first part of August. But take a look back at how July conditions helped set the stage for the situation unfolding now, in our monthly state climate summary. #cowx

A large wildfire scorches over 40,000 acres in southern France, becoming the country's largest in decades and leaving behind a visible burn scar. Authorities have reported that the fire is contained.

Most judges and Justices in the United States lack the scientific knowledge necessary to decide complex technical lawsuits. A new #AGUPubs perspective paper offers strategies to deal with this issue: buff.ly/IqIYvrH%F0%9... #ChevronDoctrine #SupremeCourt #OpenAccess

"The tropical environment should become more conducive for Atlantic hurricane activity in the next few weeks," said Colorado State University meteorologist Phil Klotzbach. "On average, our first hurricane forms in the Atlantic on August 11." Read more: www.usatoday.com/story/news/w...

It's been the 'summer of flash floods' in the US, but there hasn't been much in Colorado so far. However, it's the last week in July, which is historically the peak in flash flooding across the state, and right on schedule, there will be a risk later this week. More in our latest blog post.👇 #cowx

"The Southern Ocean is very understudied, mainly because of how difficult and remote it is. We're hoping to change that," CSU's Chelsea Bekemeier said. Researchers make the boat trip to address knowledge gaps and improve weather models. www.abc.net.au/news/2025-06...

Numerous severe thunderstorms erupt in the Central Plains and along the Front Range of the Rockies this afternoon.

was not expecting to wake up and see reports of an early-morning swath of large hail along the Front Range (apologies to those who woke up to damage.) Big hail in the early am is *exceedingly* rare. Prior to today, only 7 reports in state records of 2"+ hail between the hours of 2-5am. #cowx
