This was one of the most intense chasings in Europe I've ever had 🌪️⛈️

Am 29.8.2020 jagt uns eine Superzelle östlich von Verona, die Wolken rotieren heftig. Kurz darauf überquert ein Tornado im dichten Regen direkt vor uns die Autobahn. Schäden an Dächern, aber zum Glück keine Verletzten.

Two years ago I barely knew anything about storm chasing and meteorlogy. A few weeks ago Jerome and @aaron-stormchase.bsky.social from Sturmjäger NRW and I threw in all our knowledge and experience to make a dreamlike storm chase come true. This is how we did it: m.youtube.com/watch?v=q1b4...

Complex conditions for pot. #severeweather in S-Germany/Austria/Czech Republic.
First "loaded gun” -> long-track supercells? -> giant hail?
Later Bow Echo? -> destructive gusts? But unclear balancing of Cold Pool Boundary/Rear Inflow Jet and easterly inflow at the northern fringe of the lee low.

Thank you for your kind words! 😊 You did a fantastic navigating job! I couldn't have done it any better 🙌🏼👍🏼
It was a great day, indeed! I am grateful for being able to share my passion with such an experienced storm chaser ^^
That was an amazing chase day with @sturmkatze.bsky.social on Saturday! Check out the time lapse of the meso dumping downpours right next to it in the comments!

Notice the subvortices and the vort max to the right of the tornado merging with it at the end.

Impressive forecast soundings for tomorrow. Low LCLs and in a strip from RLP over HE to NW Bavaria CAPE, LLS and DLS overlap. This ICON-D2 sounding is between Gießen and Frankfurt. Notice the amount of streamwise vorticity in the lowest 500 m!

Some convective interest today in parts of N + central Germany in moderately strong upper westerly flow atop an upper ridge. Not a lot of forcing, but shear looks to be strong enough for a few organised storms including large(r) hail + strong gusts. #weather #stormhour @aaron-stormchase.bsky.social

So much of what I've learned in the last year about tornado (and hail!) forecasting from the perspective of a chaser can be summed up with this:
You want the most CAPE with the least water.
