July is the hottest month of the year in Colorado, and this July was the 2nd hottest on record. Records were broken for both hot days and warm nights. The monsoon finally arrived, bringing welcome rain but unwelcome flash flooding. Read more in our July summary! climate.colostate.edu/monthly_summ...

Tornado-warned bow echo with history of very strong winds moving into Chicago. That's going to cause some serious damage. (Tuesday, 10:33 CT)

August 11 8:45AM CT: Heads up to the Chicago metro area. An intensifying line of thunderstorms is approaching, and already has a history of >85 mph straight-line wind gusts. This will likely meet the derecho definition. Could be a very impactful / damaging few hours ahead.

*Big* pattern change on the way later this week, as the ridge of high pressure and heat finally fades and rain chances increase considerably statewide. Here's hoping for some real drought relief (and minimal flash flooding). #cowx

A major humanitarian crisis is unfolding in a San Juan, Puerto Rico. Hundreds of thousands of people in and around the American city are facing rolling water shutoffs brought on by an historic drought. NBC News’ George Solis reports from a well that locals are using to get their water.

These things are not the only things he was out of the loop on regarding the atomic bombing plans. As I argue in my book (mandatory plug!), I believe that he did not understand Hiroshima was actually a city (and not "purely" a base), and that there would be huge numbers of civilian casualties.

the ratio of atmospheric science textbooks authored to band members here is unparalleled

Fort Collins high temperature of 102°F yesterday sets a new monthly record for August, and was one degree shy of the all-time record high from July 21, 2005. #cowx

The devastation is unimaginable. I moved here 3 years ago knowing Spokane would be my home. I can’t explain how horrific this is. “It’s like a war zone,” people told me.

Happy 150th birthday, Colorado! Here's one of our favorite maps: average annual precipitation with color shading inspired by the state flag. It nicely illustrates the many variations in weather and climate across our beautiful state. 🎂🥳

Today is the 50th anniversary of the Big Thompson flood of July 31, 1976: one of the deadliest disasters in Colorado history. An intense rainstorm led to a rapid flood wave down the canyon where many people were commemorating Colorado's centennial. 144 people lost their lives. #cowx 1/

Significant flash flooding yesterday in multiple parts of Colorado, including the Gold Mountain and Aspen Acres burn scars, resulting in debris flows, road closures, and evacuations #cowx

Record high tied: 99° at DIA ties the daily record set back in 1963. Very early in the day to tie the record. Barring cloud cover, we should easily hit 100° and break the daily record. #COwx

July 18th, 1986: A widely viewed tornado struck the Minneapolis/St Paul metro. Described as a "minimal" F2, the twister was observed by MNDOT cameras, a KARE-11 news helicopter, and tens of thousands of residents. Several dozen structures were damaged.

Preliminary maximum rainfall amounts exceeding 20-25" have occurred during the last four days across parts of south-central TX, leading to catastrophic flooding in the area. Raining continues across south-central TX.

Getting invited to the parilla by strangers is the goal when you are in Argentina

When I was living in Buenos Aires for a bit, I remember leaving a house party at 4am. On my way out, a bunch of dudes came in and were like, where are you going? We got a bunch of meat and we’re gonna do parrilla. Anyway, asking the Argentine team to play a game at noon must be hell.

bumping this in light of another 1000-yr rainstorm in Missouri overnight. A narrow band of extreme accumulations from a 'training line' mesoscale convective system.

Russ Schumacher @rschumacher.cloud · last mo.

happy to have this paper published with @draaronhill.bsky.social We looked at extreme rainfall (up to 1000-yr storms) in gridded datasets and the CONUS404 simulation. Continuing the theme from other work, there are many nice things about CONUS404, but it is not a reanalysis of extreme precip. 🧵

So much of the (intense) focus on NWS upper air issues has been on impacts on model forecasts - but we collect this data as part of a global effort to ensure high quality data for climate and atmospheric monitoring, and the US is currently not living up to its commitments. tinyurl.com/4ys6daef
