I was having major FOMO, but lo and behold, a sizable No Kings event materialized in my hodunk town of Erie. I’ve never seen any political gathering like this in my quiet town before today.

Five years ago today, punishing and relentless winds thrashed the continental divide and foothills. In mere hours, a fire of unknown cause ignited near Jamestown, CO and quickly escalated into a conflagration consuming vast swaths of forests in vaporizing heat and flames. Here was the scene in Erie.

All meteorologists can relate.

"Some have chosen to deride the increasingly evident signs of climate change, to ridicule those who speak of global warming, and even to blame the poor for the very thing that affects them the most." BBC News - Pope Leo condemns climate change critics www.bbc.com/news/article...

Aspen season is the best season.

I’m not a big fan of the damage they do to our yard, and therefore often cheer on owls to have good meals (for the sake of a healthy ecosystem of course), but they are cute. Here’s a baby one found just now.

The Advanced Study Program’s Graduate Visitor Program Fellowship is accepting applications! This fellowship allows graduate students to work on their thesis, dissertation, or final project equivalent, with guidance from NSF NCAR scientists and engineers.

Fall weather has arrived and this rainbow fills my current field of view (when not typing this into my phone). As grim as national politics are, I take solace in the beauty offered each day by our surrounding universe.

As seen in SE South Dakota 19 years ago today.

Ahhhhh tornado continues on the ground just north of the 4-corners! It would incredible to see this out in that amazing terrain! This is from the Navajo Police Department FB page.

🌍 The MMM lab at @ncar-ucar.bsky.social is running experimental realtime forecasts with a global 3.75-km MPAS model. Goal: Highlight the power of global km-scale models for weather prediction from local to planetary scales, incl. tropical cyclones. 👉 project.mmm.ucar.edu/real-time-fo...

Our 400+ page comment on the DOE climate working group report is now out. Our conclusion: The merchants of doubt are back, and they're coming for climate science.

A spectacular "cold wake" is evident along former-hurricane Erin's track. This is a normal feature caused by strong winds upwelling/mixing cooler water from below. Erin was not only very intense but also very large, which also helps with the upwelling. The water temperatures will gradually recover.

WY once again crushing it compared to the socked in gloomy stratus of the northern Front Range.

14 years ago I flew into the eye of rapidly intensifying Hurricane Irene, which included astonishing sights of violent seas marching along, sea spray just above the water whirling by in organized, streamwise jet patterns and more peaceful conditions in the eye, including a rainbow.

My first tornado sighting occurred 34 years ago today (gulp) and it was accidental. I was on a family vacation coming back from the Canadian Rockies and this tornado dropped into view on the backside of this apparent supercell in eastern MT. I made sure my grandfather pulled over to get photos.

🤔 What happens when you divide the total wildfire burn area for each year in Canada by the total number of wildfires across the country? Oh.... Using this metric (so-called 'average wildland fire size') the three 'worst' years in the CIFFC's record would be 2023, 2025, and 2024.

The Golden Age of African Easterly Waves Starts Now

Argument mostly resolved by this super interesting and depressing figure: doi.org/10.31223/X57... Clearly we're in a new normal. Open question - do we know yet whether the new normal is more like 2020/21 or more like 2023? I suspect the latter, since Canada is so darn big & it keeps burning. /end

incredible north of Keyes #okwx

The end of the video is unfortunately glitchy, but these adjacent waterspouts at the beginning of the clip make for an eerie, unique scene

A storm just north of Cheyenne has struggled with stable air but maybe it still can pull itself together.

A typical summer day in the pyrocene.

Claim: "Water vapor is a greenhouse gas!" Reality: Yes, and there's more of it in a warmer atmosphere -"CO2 is plant food!" -pretty hard to eat when you're on fire -"Climate has changed before!" -We know, we told you that -"Scientists don't know everything!" - doesn't mean we know *nothing*

I am not a fan of this weather.

Our backyard has become a vacation resort and spa for all of northern Colorado’s rabbits.

Excited for the public dissemination of our HRRR-Cast model development to begin! For those interested in more details, the manuscript is up on arXiv: www.arxiv.org/abs/2507.05658 (1/2)

Cat update. They chose this over running High Lonesome 100.

So true.

A decent thunderstorm, timelapsed from Erie, CO.

It’s 5:30 in the morning and 79F in Boulder, apparently 88F in Broomfield. The atmosphere is definitely having a normal one.

🧪 BREAKING (good news): Senate subcommittee says NO! to Trump's proposed slashes to NASA & NSF funding. Today, the subcommittee said to keep NASA + NSF funding at $33.9 billion, the same as in FY24. See 7:15 below. Full Senate appropriations committee meets tomorrow about it. 🧵 1/3

Exactly. This is a slide from my mesoscale class on flash flooding (mainly just taken from Doswell et al. 1996)...this event hit every one of these bullets...

Beautiful example of a thunderstorm likely influenced by the urban heat island effect.

Not going to lie, I cried a bit when I got the email that SSMIS was being discontinued. I developed D-MINT with a toddler in tow, showing her pretty pictures of hurricanes so she knew what Mommy did while she's playing with friends at school. This one hurts.

This run of storms in Erie is approaching 3 hours. One of our most remarkable runs of heavy storms since I lived here.

Stationary supercell over my house for last hour

Big news for our public lands—Republican attempts to sell off our public lands using reconciliation do NOT pass the Byrd Rule. The Parliamentarian also finds their sneaky attempts to undermine NEPA and mandatory oil and gas leasing and permitting schemes don’t fly. This is a huge win!
