This is the most infuriating part of data center and water discourse. Alfalfa exports use way more water than data centers, and no one cares.

Had some flash flooding last night in Grants. The ripple marks are in sediment deposited on the road above a culvert. We had 1+ inches of rain in less than an hour on top of the mesa. Gravity took charge after that. #nmwx

So, my games are just a little old. I think the median release date is the 1990’s. my9games.com/en/s/56c7bb0...

That was the culmination of a brutal summer forecasting TC’s for Loon, we had a launch site on the eastern shore of PR at former NAS Roosevelt Roads, and I had to forecast the likelihood of tropical storm force winds 72 hours out since that was how long it took to button up the site.

Completely befuddled. Especially when I answer the question, “Well, how did you get here?” Letting the days go by…

In ye olden days this would be a gargantuan pair of county warnings including both Grants and Rio Rancho. Kids these days have no idea.

This is a really good paper and fits the strengths of the coding LLMs (independent oracles keep the agents in line). Whats going to be hilarious is when Reviewer 2 uses your toolchain to prove you’re wrong.

Just to add on to this, Malpais.app started because I wanted to see if using the ICDs, could Claude write a L2 parser. And now it’s my daily driver for keeping track of my local weather.

A brief word about naming conventions for Malpais.app. Though bodies of water are not currently labeled, the canonical names include the Gulf of Mexico and Lake Ontario. And my state is New Mexico. Thank you for your attention to this matter.

Ooh, I’m retired now, so I can say that this was not great for the geosciences either. I didn’t understand how switching from a quantified metric with known issues to unquantifiable metrics that could be gamed would be an improvement.

I've heard reports of snow on Mauna Kea as #Lala passes through. This cross section of reflectivity from PHKM on the north side suggests that's it's snowing HARD. We now have terrain in malpais.app thanks to @mapterhorn.com malpais.app#v=3&s=PHKM&m...

This thread is an exemplar of the failure modes of Bluesky. A historian posts a history paper created by Fable 5 as a benchmark of the current state of the art. The result: General AI rage, users raging without reading the thread or linked material, and overall just lack of good faith engagement.

@stormscale.io Since there's a live Flash Flood Emergency, I thought I'd share how my app handles the IBW tags. Basically, Emergencies float to the top of the warning list and the borders are very thick. I'm open to suggestions/comments since I'm not a UX guru. malpais.app#v=3&s=KJKL&m...

I've been watching this storm from the kitchen window for the past hour or so, it's been a great lightning producer. On the 3D radar view from malpais.app, you can clearly see how multiple updrafts are feeding the same stratiform layer. Really neat. #nmwx

Last night was some pretty bad flash flooding in Gallup, NM, the El Rancho Hotel reported 4 feet of water in the basement. The moisture is still hanging around, KGUP's dewpoint is a muggy 53F. This is the view I'm using to maintain situational awareness: malpais.app#v=3&s=KABX&m...

New update for malpais.app: permalinks. Every scan resolves to a URL, everything's encoded in a fragment: site, timestamp, tilt, layout, even warnings/LSRs. Doesn't go to the server, so it doesn't get logged. No more re-navigating to show someone what you saw. A few from this year's worst days:🧵

I'd be shocked if this was actually in the City of Dallas, it's quite blue. Much more likely to be Arlington, but really, as any devotee of @lyndonbajohnson.bsky.social know, southern Denton County would be the most spiritually appropriate location.

It's new feature Friday for malpais.app! You can now look at the last 5-30 minutes of GLM lightning flash locations as an overlay. It's useful for assessing storm intensity trends and motion at a glance. Just go to the Fire/Lightning tab on the left and click the Enable toggle under Lightning.

With TS #arthur, now is a good time to announce some new features for malpais.app, my Nexrad viewer app. You can now load current surface obs (METAR/RAWS), plot the objective analysis of T/Td/RH/altimeter/winds, and for the wildfire monitors, we have incident locations/perimeters. (1/x)

It's an air-mass thunderstorm kind of day here in Cibola County, NM. Some orographic convection tried to form over Mt. Taylor, but just didn't click. The biggest storm right now is over Acoma Pueblo lands. KABX L2 data visualized using malpais.app

So, a few updates for malpais.app 1) You can have up to 4 panels at once to look at different moments or Level 3 products at the same time. 2). You can load RHIs (range height indicator, a cross section along the radar beam. (This is from a weak storm over my house today)

Ok, pushed the fix for this (coordinate systems are fun) and also the first steps towards METAR displays (if you hover over an airport with a metar, you can get the flight conditions, temp, dew point and winds. Click and you get the raw METAR)

So a dust devil just rolled over my house as I was unloading the van. I figure the dust plume was at least 2-3 stories tall. There may have been a topographical assist from Grants Ridge just to my west. #nmwx

Saw some dust devils around Grants, today. Even got to chase one in the minivan for a bit. Given the general lack of supercells on the Colorado Plateau, it’ll do. @vortexjeff.bsky.social @kmkanak.bsky.social
