MS/LA border, watch out

I don't mean there's a watch out. There is, but I mean batten down the hatches. There's a supercell that's discrete and already quite spectacular. What's more, it's moving into an area of higher moisture, instability and shear. This storm could end up going nuts. I therefore hereby eat crow in pooh-poohing Justin's previous forecast.

Here's the significant tornado parameter, the worst of which the storm is moving into.

And the shear. No, this isn't deep shear; this is 0-1 km! Yowza!

    Have you seen the velocity couplet on this cell? Absolutely amazing!

  2. Oh, and to add to that: A report just came in on WAPT 16 (a news channel in MS with a live feed on the internet), stating that a 3/4 mile wide tornado went through Yazoo City, Mississippi, all thanks to this cell.

  3. Yeah just before it passed by Yazoo it had a gate-to-gate shear of 195 knots. At 3000 feet. Yowza.

  4. 195?! WOW. I was hearing 145-160 gate to gate, but 195? Insane.
