Alrighty, ready to see something really cool? (and maybe a little nauseating) The evolution of Hurricane Melissa's mesovortices at peak strength.

#Melissa's landfall intensity of 185 mph/892 mb ties it with the Florida Key's Labor Day Hurricane of 1935 as the record minimum pressure of any TC making landfall *anywhere* the NATL basin. I feel for the residents of #Jamaica 😞 Zoomed in G19 visible meso loop courtesy of @cyclonicwx.bsky.social

Sunset on Hurricane Melissa. Plenty of lightning in the eyewall indicates strengthening.

Mosquitoes found in Iceland for first time as climate crisis warms country. Three specimens discovered in what was previously one of the few places in the world without the insects. www.theguardian.com/environment/...

The new hurricane season should start where the last season left off, not at A. Also, EF-0 tornadoes should be classified as something else. Those will always and forever be my two takes that no one asked for.

Uruguay, y'all. I been sayin.

I finally broke down, for the first time recruiting AI in an effort to rewrite some copy (for a personal project and not for work) and I'm hooked. I'm not scholarly enough to compose 19th Century American English but ChatGPT instantly produced some stellar syntax.

One of the first ten laws we should pass when DC gets to be a state is no more fucking helicopters in our airspace.

DC has seen the number of EXTREMELY humid or GROSS days (dew points 75+) each year increase by 10 since the late 1970s according to an analysis by The Washington Post's Ben Noll Read the full analysis: wapo.st/46mpcbh

An hour and a half later, this oil and transformer fire at the Benning Road plant is still raging. Meanwhile, federal agents continue arresting people on DC-295 below the plume of smoke.

@markellinwood.bsky.social I know this isn't exactly your dept but I'm wondering if you know how your weather stations get installed on buildings not owned or occupied by the purchasing station. For example, how WJLA has control of cameras on hotels.

We've reached the "breath condensation" stage of fall.

⚡️Rainier Lightning Storm⚡️9/6 Nothing quite like the rumble of thunder through Mount Rainier National Park! Prolific lightning, rain, pea size hail and some nice CGs and crawlers made for quite the show last night! Image taken during a clearing in the rain, approx 10:45pm. #wawx #wxSky #MountRainier

ESPN trying to act like there's empty seats in a semifinal because it's past midnight in NYC when we know it's actually because you need to take out a second mortgage to go.

A police or military drone just silently yet suddenly flew directly over me, doing an arc < 50 feet overhead, then careened at full tilt over the tree line over Western Avenue. Modern life on the DMV's DMC.

It's the best time of the year for backyard scavenging.

The track of an ultra important mission certain to end with many accomplishments that's definitely worth the $3k/hr in fuel. @ianlivingston.bsky.social

The Army is tracing I-66, US-15, and the Beltway this evening on their $3,000/hour sunset cruise.

August 2025 had no severe storms around D.C.

Update on Hurricane Erin's size evolution as of 15 UTC 19 August. The shaded area represents the extent of its 34-knot (tropical storm force) winds from this morning's NHC advisory. Larger area of winds pushing around the ocean surface means more rough surf and rip current concerns for coastlines.

Error message on the lobby directory is on point

"It's incredibly dangerous in D.C. right now... no one feels safe." TBH random, armed dudes in brownshirt camo body-snatching people without accountability does make me feel a bit unsafe.

Breaking! Looks like every region is either wet or snowy this upcoming winter. Thank you to the hundreds of news outlets that reported on this story. #LockItIn 🌧️❄️

More heat-related medical emergencies in Cinnci. Players and fans succumbing to it in Canada, DC, and Wimbledon this year more than ever. And yet we schedule noon matches, sit in the midday sun, and keep burning as if nothing is changing.

I knew a lot of X was just bots now, but I had no idea it was 3/4 of the site. Keep that in mind the next time someone writes an op-ed that if you're not on X then you're in a political bubble.

From the park

There’s something you don’t see every day — an MCV moving east to west into California towards the Death Valley region:

There was some lightning yesterday

Every July day in DC is like: high of 92F, low of 74F, dewpoint in the 70s around the clock so good luck opening your windows even at night, chance of cataclysmic thunderstorms all afternoon/evening, or it might just be super hot and you’ll be drenched in sweat after 2 minutes, flood watch until 3am

I had the WTOP camera pointed exactly where it needed to be this afternoon. ⚡️⚡️⚡️

The NWS in Sterling has issued a Flood Watch in effect from now through the heat death of the known universe.

For the sky people and star gazers out there: Meteor, or something else? 9:45 p.m. ET, looking northwest from the Pentagon in Arlington, Virginia.

For the record, X and other social media platforms are used to *supplement* NWS messaging and is not the official notification. There are other pathways that are official and faster like feeds to local media, NOAA Weather Radio, and WEA activation on phones.

Celebration through poison

Blissfully ignorant happiness

Earlier tornado and supercell structure in western Beltrami County, MN. This was at 7:34 pm in the woody marshlands, looking NW from near Malcolm, MN.

Posting a crisp photo of an orphan anvil that is probably going to be compressed to death by Bluesky

Pretty wild to still be seeing PDS SVR warnings well behind the now-dead convective line of a derecho (probably because the secondary eastern LEWP that developed along with the tornadic supercells in E ND earlier has taken over and will become the new MCS...not sure if it will go derecho, though).

Single shot 70mm from yesterday. Ghostly. Etherial. And a photo I'll probably never be able to top! Dickens, Nebraska. 6/16/25

Day #5: The best structure/tornado combo of my career south of North Platte, Nebraska

Tornado-warned storm in Virginia seen from the Blue Ridge Mountains.

There it is. The first ever Heat Advisory issued in Alaska. This is the first year it has been an option. @alaskawx.bsky.social

New research from my colleagues out today looking at the environmental and social impacts of food crop-based biofuels in the US, where we now use >30% of the corn supply and >40% of the soybean oil supply (on tens of millions of acres of prime cropland) to produce only ~6% of US transport fuel. 🧪
