NOAA GOES 18 weather satellite’s Geostationary Lightning Mapper (GLM) instrument detected the atmospheric re-entry of NASA’s Artemis II Orion capsule over the Pacific Ocean between Hawaii and southern California just before 23:56 GMT — too cool! #ArtemisII #NASA #NOAA

Raucous wind storm ongoing in the mountains of western Boulder County. Estimate gusts in the 80-90 mph range at my exposed location. I really won’t ever get used to the way west-facing walls bow in and out with stronger gusts. Pushing the mantle around enough to slosh a glass of water pretty good.

Cool to see — two commercial aircraft passing in close proximity to each other in northern Montana currently, with their air speeds showing the difference between either fighting or drafting a 130 knot WNW to ESE jet stream

Message exchange about the ongoing absence of winter in the Front Range. “Barker” is Barker Meadow Reservoir at ~8300’ in the mountains west of Boulder. I my time living in Ned, I’ve never seen Barker this ice free on Mar 1…nor seen much precip fall in liquid form. Wild.

The Platforms™️ promote people to being the main character in a video game of multidimensional human drama based on real life events. Narcissism epidemic follows closely behind, seemingly.

Constitutional cosplay is so annoying. What I don’t buy is the idea that public indifference is some higher civic virtue. If you think engagement is worse than apathy, put up an argument or shut up.

Process is irrelevant if people don’t care about basic civic responsibility

You’re describing my childhood obsession. Coins. Banknotes. When I first saw a “HAWAII” note, I felt like I began to understand geopolitics just a wee little bit. I was 15.

I really like RCV…but, yeah, what you said 😔

From friend reports, mPING, and remote cams that I maintain near Lake Stanley Draper, it started as a period of sleet…but, it didn’t take long for saturation and lift to flip it over to all snow. Big snow event for C OK.

I love views like this — looking southwest from 40,000 feet over Liberal, Kansas at the demarcation between bare ground and snow cover left in the wake of the recent storm system

Winds have eased some here in western Boulder Co. after last night’s blitz — strongest in 7 years here. My low-height (~1 m AGL) cup anemometer peaked at 71.9 mph. I suspect a standard 10 m measurement would have been 100+ mph. House’s west wall bowed with the gusts. Short vid from 12:20 AM. #cowx

Wow winds really ramping up very rapidly in western BoCo (Nederland) at this time. Currently (~10:35 PM MT) I’m recording gusts approaching 70 mph on my cup anemometer, which is only 3 feet above ground…and the worst is yet to come. #cowx

A low temperature of 46°F here at 8450 ft AMSL this morning. It’s often cooler than this in July. Also, I’m not digging these < 20% RHs.

I did “chase” it and had some pretty sketchy encounters with an embedded nighttime tornado (EF1 near Minco) and terrible flash flooding. The US Highway 81 bridge over Buggy Creek on the south side of Minco completely washed out probably a few minutes after I drove over it 😱

The “other Erin” — spooky that OTD in 2007, the arguably most fascinating weather event of my career unfolded: the overland reintensification of TS Erin in OK. I was fortunate to contribute (as the final co-author) to Arndt et al. (2009, BAMS) on this event while at Oklahoma Mesonet

0.3” in the tipping bucket here near Barker Res. Good moisture but was more impressed by the light show.

I’ve been having the same kind of logical deadlock on this. Haven’t squared the circle and haven’t seen anyone else really come close, IMHO, either.

‪Fire now 100% contained and Boulder Canyon Rd has been reopened in both directions. Response was rapid and forceful. Thank you firefighters and first responders!‬

Witnessing strong tornadoes with no shroud of obscuring precipitation around them feels like catching lightning in a bottle.

This is an awful development. Unidata has done more for the advancement of the atmospheric sciences and broad technology/scientific collaboration through open data, open-source software, accessible training and educational initiatives — among other things — than I can count.

One of many tornadoes produced by supercell “A” during the May 3, 1999 tornado outbreak. This is tornado A8 as I observed it approaching the municipal airport on the northwest side of Chickasha, Oklahoma. The next tornado in this supercell’s sequence was A9 — the Moore F5.

As mentioned by SPC 20Z Day 1 outlook update maintaining the High Risk — check out the dramatic effect deep-layer ascent has had lifting the capping inversion into veritable irrelevance across the Mid South as shown by WFO Little Rock soundings between 12Z to 18Z. Wowzers!

Well. This is a pretty framable VAD hodo from Paducah, KY at this time. Tornado outbreak ongoing.

Constituent here, @neguse.house.gov. Being in the private sector weather enterprise, I can say these actions of DOGE are shambolically reckless. NOAA is essential for private sector weather-focused businesses which create multi-billions in economic value — not to mention their public safety role.
