Remarkable evolution of Hurricane Polo over the past 48 hours as it fluctuated between category 4 and 5 intensity during an eyewall replacement cycle (ERC) and subsequently re-strengthened to 180 mph (155 kt) as of the latest NHC advisory.

Indeed. “Forecasting where weather systems are headed rather than simply assessing where they are” is literally the job of the NWS, and they are exceedingly good at it.

Hurricane Polo's rapid intensification is seriously impressive... A special 19Z update was issued by the NHC stating that reconnaissance aircraft found that Polo's central pressure is sitting at 892 mb, the 2nd strongest EPAC hurricane by pressure only behind Hurricane Patricia (2015; 872 mb).

This is a widespread problem, and not just in the tech sector. People with success and expertise in one area assuming that makes them experts in another, if they are even aware of it’s existence to begin with. We need to encourage a more well-rounded education in higher ed, along with humility.

At first I thought that “Rapid Response 47” must just be one of a horde of MAGA troll accounts. Then I learned it was an official WH account. Then I realized that my first assessment was no less accurate…

Well worth a read. Kelton’s experience with and nuanced approach to AI-assisted coding largely mirrors my own. A huge part of me that feels like the advent of the latest generation of AI coding agents is exactly the “spare brain” my single ADHD-addled one has been looking for for so long.

Today's FORTRAN tip. When editing IF statements, make sure that you don't add "THEN" to what is actually a *logical* IF statement with a continuation "&", so that it *looks* like it should be a standard block IF (i.e. IF-THEN-ENDIF). Confused the hell out of me, the compiler, *and* an AI agent.

Want to see how smoke affects temperatures without seeing any temperatures? Away from the thicker smoke, enough sun came through to warm up the ground to create cumulus clouds (and even storms). But areas with thicker smoke weren't as warm, and so those puffy clouds didn't form.

It's like dusk in Albany right now with a very thick layer of smoke blocking out the sun and an orange tint to the sky. Approaching the same feel as June 2023. Smells like campfire outside.

The ongoing MCS in IL is quite a bit more robust and intense than previous CAM depictions. At this point I think it is likely to pay a much bigger role in today's severe potential than I had thought yesterday, especially in IN where there may not be enough time to recover ahead of the second round.

The severe wx setup in the Midwest for Wednesday is one of the more impressive I have seen in a long time, with a springlike system mixing with summertime heat and instability. PTC1 also is a big flash flood threat for The Gulf region, particularly from SE TX up into MS. tinyurl.com/bdekjztt

Forecast soundings along warm front in IL and IN tomorrow are insane. Don't recall the last time I've seen > 100 kts of 0-6 km shear with an unstable thermo profile (below is from NAM 3km, but HRRR is similar). Multiple CAMs showing intense supercells training along or just north of the warm front.

A few unprocessed photos from our chase yesterday in northwest IN. Not my best. Distance and lighting were problematic, and was dealing with a fogged up lens at times. It was tough keeping up with the storm. But it was a good chase nonetheless.

I don’t know who needs to hear this but the dark side of the moon and the far side of the moon are two different concepts. Far side: side always facing away from Earth. Dark side: always changing as the moon rotates on its axis once every 27.3 days. They coincide only when the moon is full.

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕
A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)

This essay is fantastic. It articulates almost perfectly my feelings about both the promises and pitfalls of generative AI in scientific work. So many excellent points, but to sum up: genAI can be a great tool, but cannot replace true learning that comes from trying (and failing) at doing science.
