My latest book--The Skies Above--is a celebration of what we overlook when we look up. I cover everything from asteroids to hailstones, and even why every rainbow you see is unique to you. Get your copy today! damweather.com/the-skies-ab...

When I'm having a bad day, I reframe it by pretending I'm showing the future to someone from the past. "Cell phones are computers now. You can wirelessly send any song ever made to your car radio. Those election signs? We've been fighting fascism for 12 years. Oh, and we have a Starbucks now!"

This past weekend, Google DeepMind was the only model that pegged Cyclone Arnab hitting Cat 4 intensity by today. All the others kept it Cat 1 at most. Lo and behold:

My best friend landed a hot boyfriend and I'm doing my best to follow in his footsteps.

That was disgusting and I feel like a barnyard hog. I loved it. Can't wait to have it again in 2032.

I haven't had this in six years. It's Intern Roy approved!

Google DeepMind has proven to be an incredible tool and folks reflexively bashing it should read up on how beneficial it's been for forecasting.

Brazil and Serbia beat back fascism this weekend. The U.S. will do it in 9 days.

Brazil's election results right now are like Stay on the boat: 49.972% Get in the Titan submersible: 50.028%

The same satellite pass caught these puffy clouds drifting across North Carolina's Piedmont Triad.

Thanks Google! Because when I think Alaska, I think Mindanao.

Copernicus/ESA's Sentinel-2 caught this beautiful view of the fall colors across southern Ontario yesterday afternoon.

Astrid casually showed up in her bath towel and held me hostage in my living room for ten minutes.

And that's why you don't call a snap election in the middle of a global anti-incumbency backlash.

My hair's messed up and I need to shave, but at least I voted. ✅🌊

My mom when it's time to leave the house: "hold on, wait, I have to clean behind the stove real quick"

Since this president took office, we've seen: - NWS layoffs hit short-staffed offices - Reduced weather balloons directly affect forecasts - Shutdown of NCAR as political retribution - Funding/data cuts to next-gen satellites - International weather observations blocked What's next?

Heck of a closing message to swing voters with 11 days until polls close.

The NWS intentionally blocked off international observations without issuing any service change notices about it. If anyone in the agency has information on who ordered this change and why, my email address is my name at gmail.

People try to pretend that today's politics is "just a difference of opinion" when the President of the United States is defending heinous child abuse so his party wins.

Another rare tornado watch is up for parts of the desert Southwest through this afternoon and evening.

This is not the future Donald Fagen promised me in I.G.Y.

Holiday Inn Express never made me do chores.

This is the kind of scandal we used to enjoy. Letterman would do ten minutes on it. There would be email forwards.

Does anyone know if Pogo is affected by the EA cuts?

I know the polls are generally accurate when That One isn't on the ballot. But man...something's got me uneasy about it.

Today's tornado risk in Arizona is very rare, but so is the potential for 2"+ diameter hailstones. SPC's database reflects just 35 reports of 2"+ diameter hail in Arizona since 1955--or a little under 3% of all the state's severe hail reports.

We need to take a moment to appreciate how rare this particular enhanced risk for severe weather is out in Arizona… - First 5% tornado risk since Aug 2023 - First enhanced risk since Sep 2019 - First enhanced risk to include the Flagstaff, AZ CWA in the modern 5-category outlook era. #AZwx

I just bought a snow brush and an ice scraper for my car, so that guarantees it'll be 65 degrees on Christmas.

I'm in Walmart and an older woman with a syrupy accent just called me "lovebug" and I think it added five years to my life.

I'm gay as hell and I don't talk about men like this.

I made a TikTok recipe tonight and it turned out exceptionally well. Very rich, but very good. Here's the recipe I followed: www.tiktok.com/t/ZTfk1D47B/

Super Typhoon Champi now has 185 mph (160 kt) winds and a pressure of 895 mb, making it the world's strongest storm so far in 2026 in terms of winds. Hurricane Polo in September had a slightly lower pressure (892 mb) but slightly 'weaker' winds at 180 mph.

A rare and significant risk for severe weather will develop over parts of Arizona on Wednesday. Very large hail (2"+ in diameter), damaging winds, and a couple of tornadoes are possible. This appears to be the highest categorical severe weather risk on record for both Flagstaff and Prescott.

I switched from Spotify to the radio and they were playing the exact same song I had on, just a few seconds off. I thought my radio glitched out for a second.

Elizabeth Dole's "there is no God" ad against Kay Hagan got her run out of North Carolina. Ramaswamy's disgusting attack against Acton should get him run out of public life, period.

I actually said "wow" out loud near the end.

I read the Alberta referendum questions and some of them were incredibly leading. Holy moly. North Carolina's amendments this year suck (as usual), but at least they use straightforward language. 🥴

32°F right now. 😍 I'll have to check the last time we strung together three freezing mornings this early in the season.

Kim Jong-un Death Rumor season starts earlier and earlier every year.

My lunch was inedible and I got into an argument with someone who yelled at me at an intersection. This day needs to end.

This alert probably could've stopped at "Supreme Court agrees to review Reconstruction."
