Tornado risk has been bumped up.

This is a nasty, nasty setup. It’s one of those events that seems to have pretty much every parameter in place for it to be a big day.

Guess I’ll be happy with just a 15% chance of tornado right now considering the percentages to the west of me.

They can be too good sometimes, can lead to clusters. Unfortunately, it's out in dry W OK and TX, so too much moisture is a lot to ask for.

It's going to be dangerous chasing this evening because there's a great rainfall potential in place in Oklahoma. Hunting wedges in the middle of nowhere, with potential flooding is a scary proposition.

Looks like I'm going to be printing some upper air charts and surface readings off for some hand analysis today too. Good day to do some learnin

Damn, bro. I think that is what the % was for the April 27, 2011 tornadoes that ripped through Alabama.
Have your plan in place now for you, your family, your pets, your friends

But, I hope he's got his family prepared, too.

I've watched the local news coverage of the 2 F5s that went through Moore, Okla... Tinker AFB barely missed getting hammered by both

ETA:
YouTube - KFOR live coverage of Moore F5 Tornado 5/3/99
YouTube - KFOR live coverage of Moore EF5 Tornado 5/20/13

It was a 45% hatched on 4/27 too to highlight the potential today.

That day still sets itself apart from a forecasting perspective because of the >95% chance of all severe modes in one of the PDS watches. I'm curious if today will come close to that.

I had a friend whose wife stuffed herself into the fireplace when the Wichita Falls killer tornado came through in 1979. She survived uninjured. The tornado was so wide she thought, at first, that it was a big rainstorm.

I saw they preemptively closed a lot of schools in the storm crosshairs.

So it’s not just a Louisiana thing.

I'm in a 2nd floor room at a hotel in OKC. I don't know what to do in a tornado scenario.

put your head between your legs and kiss your arse goodbye




seriously though... get on a low floor and in a hallway or bathroom... since you're in OKC they may even have a special severe storm room to go to so you may want to get a lay of the land quickly

Warm front drapped over OK. Dry line in NM pushing toward Texas. Watching the dry line for the spark this afternoon. There's a big swatch of 70+ dew points toward central TX and into southern Oklahoma.

CAPE pushing 5500 in parts of western Texas (think a line starting about Lubbock and east of there). So plenty of juice. Looking at some convective inhibition in the Texas, suggesting the high risk zone is well placed to the SE.



Lines are convective potential energy (CAPE), 4000+ is high. There are 5000+ pushing into the high risk zone. Lines are drawn for every 500 J/kg. Light blue shading is convective inhibition (CIN).
