  1. Big tornadoes incoming on the Sycamore and Elgin cells most likely. Bad, bad, bad.
  2. Going to have a real problem for Chicagoland over the next few hours. All of these storms have been efficient in producing tornadoes.
  3. Given the timing of these things, it looks like they'll approach the metro right at rush hour. Not ideal... There's also one or more boundaries draped across the general area where they'll track.
  4. Those hodographs blended with stout low level buoyancy are going to be a problem if we get at least transient supercell structures.
  5. Well the 18z HRRR would be a bad scenario for just about all of Chicagoland. Also Boscobel WI tornado from yesterday rated EF3, 150 mph winds.
  6. https://www.facebook.com/1339856211/videos/593029138361331/
  7. Some really rapid motion in this video from Boscobel.
  8. That's a major tornado there east of Boscobel. One of the strongest signatures I've seen this year.
  9. Speaking of La Nina, this is quite the rapid subsurface cooling occurring over the past month or so. Now ahead of last year's pace at this time.
  10. Without further analysis, I'd have to think that the La Nina decaying quite early may have been a factor.
  11. Supercell coming into the northern Philly burbs as we speak bears close watching given what happened just up the road.
  12. Video of the tornado from Insta. https://www.instagram.com/p/CRXAHXQFPyN/?utm_medium=copy_link
  13. Lol I was about to be like "whaaaaaa". Cedar Rapids might have a problem here shortly with that cell on the southern end.
  14. There literally was a spotter confirming it at the time and a TDS showed up the scan after. Now have this.
  15. Tornado ongoing west of Lake City, IA, heading towards town.
  16. Tornado watch out for Iowa, 50/20 probs. Edit: 10% tor now in the 20z D1 update.
  17. Differential heating boundary draped north of I-80 in Iowa looks to be the focal point later. Mesoanalysis progs have large 0-3 km CAPE in that zone and there should be a fair amount of near-surface vort with backing surface winds in its vicinity.
  18. Matt Petkovic is a clown, wouldn't trust anything that guy spews.
