- NEW to @chasearchive.bsky.social: check out over 300 old and obscure tornadoes from 1900-1990! We're virtually done archiving all "famous" photographs, so if there's a tornado you're looking for, odds are we have it here. Look at how active the 1950s were alone! app.chasearchive.com?q=1950-1959
- I'm convinced the ucar archive walked so that chasearchive.com could run Let's give @ameliaurquhart.bsky.social and @stormchasertang.bsky.social another round of applause
- 2 years in the making: a RAP-based, track-based, full-sounding analog system. Here's a hypothetical forecast for the Cole, OK tornado on 4/19/23, where it predicts large hail and the potential for deviantly-moving EF2+ tornadoes.

- Perfect demonstration of the fact that you don't need straight hodographs to get left-moving supercells (In this case, storms are rooted at ~2km)
- Ever feel like your town gets more nighttime tornadoes than others? Here's a map of tornadoes by time of day (nighttime tors are plotted on top of daytime tors to stand out). I feel for you Tulsa, Jackson, Birmingham, Nashville...
- Fantastic example of hail doing what it wants (Preferentially produced by elevated supercells north of the greatest perceived risk, even though both targets featured supercells)
- I was simply beam-ing when I took this last night 📍The Wichita Mountains, OK
- 8 months ago I had a vision: what if we had a unified, track-based dataset of all severe events? Still a lot of improvements I can make to the algorithm itself, but otherwise, looks like we have one now. I can't wait to see what we can do with this 👀
- Tornado tracks by rating (left) and duration (right) While highly rated/long-tracked tornadoes are biased towards the Southeast, long-duration tors are found even up to the High Plains. Credit to @theasandmael.bsky.social for her incredible dataset!!

- Next up, wind swaths! 🌬💨 This was created solely using report clustering (no other gridded data). Plenty of events across the entire US, but can see the most intense storms from the Great Plains into the Midwest! 🟦
- Ever wondered how hailstorms vary across the year? Here's all radar-estimated hail swaths by month since 2011. Love seeing the northwest flow monsters come alive June-August! [MRMS MESH > .75", colored by max hail size]
- Actual hail swaths per MRMS MESH >= .75", colored by measured hail size. I'm not sure when the world will be ready for this kind of data but it sure is sweet
- Here it is. The last 10 years of hail events across the U.S. using my prototype hail tracking algorithm! Hoping to build out a more robust climatology of hailstorms like we have for tornadoes.
