A Guide to Cold-Core Tornado Environments

[@Neonownz]

This is a great video idea, you should definitely do more videos on "sleeper" synoptic setups that most people overlook when learning to recognize severe setups from models.

[@ConvectiveChronicles]

Thank you; I’ll add that idea to my list!

Another great post. An advanced meteorology seminar that the layman can understand. Now for my annoying request: a case study of the 2013 El Reno tornado. Definitely a lot out there already. But doesn't seem to really present all the unique factors that came together in a perfect storm that day. Your case studies are the best. Cheers!

[@ConvectiveChronicles]

Thank you very much for the kind words! El Reno 2013 is definitely on my to-do list.

@@ConvectiveChronicles awesome! Can't wait to see it. Thanks!

[@cschammel]

Your videos are always excellent! I was looking for info on cold core setups today because of the storm in Iowa and here is a fantastic resource. Thanks so much for putting this out there!

[@ConvectiveChronicles]

Thank you! Glad you found this video helpful!

I like how the first example event you referenced was my first time chasing ever. Followed that arc of storms up to Nebraska and caught a glimpse of the Bern, KS ef3 from about 15 miles away lol

[@ConvectiveChronicles]

Wow, very nice! Was a great event to have your first chase!

Great video as always! I sort of recall a cold-core like environment setting up on May 25, 2011 which produced numerous funnels alongside a few tornadoes in the Kansas City metro. Looking back it might seem more of a cold core-esqe set-up. Storms fired in the wedge between the cold front/warm front around 10am when they started producing those tornadoes. Dews were in the low 60s but 500mb temperatures were around -18 C. Very interesting. (This was the same system that brought the Piedmont EF-5 a day before, and produced many strong tornadoes in SE Missouri and friends that afternoon)

[@ConvectiveChronicles]

Thank you! Great points...that setup for the KC area definitely had some cold core qualities to it. Surface low was tucked up underneath the center of the 500 mb trough, and those tornadoes occurred right on the surface low.

Thanks for doing these!!

[@ConvectiveChronicles]

My pleasure, thank you for watching!

Not sure why I never commented on this one but I will now. Cold Core Set ups are to me one of the cooler set ups you can get in just how significant of a tornado outbreak you can get with these. Physics be it as it may but there's something so cool having such an active tornado set up right near the actual low pretty cause sometimes the satellite can be so eye candy. That said these I think are the most persistent boom or bust tornado set ups too cause there's been a lot of times where these storms don't stay discrete long enough and it turns into a mega wind event.....though that's ok too as the shelf clouds you can get from these are insane. I can't remember which of which were some cold core ones we have done in June. I don't think we have done any that I can think of last 5 years of the mid-June chase trips

[@peachxtaehyung]

You brought up the 2019 high risk in Oklahoma I was wondering have their been any findings on why it wasn't AS horrible as it was predicted to be that day in Oklahoma? I mean everyone talked about it like it was going to be another may 20 2013 situation

[@ConvectiveChronicles]

Yes, there has been some research showing a bit of subsidence (sinking air) aloft that crept in, although the source of that subsidence is not certain.

[@peachxtaehyung]

@@ConvectiveChronicles oh wow that's crazy that it just sneaked in there and no one can really figure it out!! Anyway thank you for letting me know because I've always been curious but I didn't know where to look!

[@ConvectiveChronicles]

@@peachxtaehyung You bet...we were just a couple degrees too warm aloft from it being a generational outbreak.

[@paradoxicalpoet1525]

Awesome stuff as always!

[@ConvectiveChronicles]

Thank you!

[@harryparsons2750]

Are nor Easters warm or cold core?

[@ConvectiveChronicles]

Cold core. They are basically your typical mid-latitude cyclones (low pressure system - cold core by nature), only it occurs over the ocean instead of over land.

[@Cleanse_]

and just a few months later there were multiple cold core setups

[@MattMorganJP]

You said low shear but adequate shear, the cold core tornado says "no cap".
