"To be clear – this is not a price chart. It’s a valuation chart. It aligns precisely with the happiest and most satisfying moment of a speculative bubble: the point where wildly misaligned expectations for market returns are being realized anyway – via self-fulfilling speculation."

Yes, based on results from the SHAVE project, MESH-based hail swaths appear to do a decent (even good?) job at identifying the extent of the swath.

Looks like you're missing the 5.5 inch hailstone near Lela, TX on 13 June.

Farm country.

With the recent giant hail events, as we approach the 12th anniversary of the El Reno Storm, I want to highlight my related WAF article:

Also, from my NSSL teammates (at that time; Robin ‪@tornatrix.bsky.social and Pam‬):

Relating to this giant hail event is a poster I presented at last year's SLS conference on a radar-based analysis of similar past events:

Five of us at NSSL took the buyout and retired yesterday. It has been an enormous privilege to spend >40 years of my career at such an outstanding research lab. The NWC is a wonderful place to work. In these troubling times, it is fortunate that NSSL has excellent senior managers (DaNa, Pam, Kurt).

Could get very interesting across southern OK later today if the 17Z HRRR forecast is accurate. Here's the Updraft Helicity Swath prediction thru 01Z:

Not familiar with Tangerine Dream? Give these a listen:

Charly The Kid and Perpetual Motion - two short, very delightful tracks:

Calymba Caly (1980) - the first 4 minutes are fantastic:
