Severe Weather Threat 4/25-4/26, 2024 - (Thursday, Friday)

[TornadoFan17]

weeks and weeks of underperforming setups and then this which will easily have supported a high risk.

Welcome to 2024.

Brett Adair deserves to be the storm chaser masterclass of all time after this.

IMO, he was and has been. Great guy and just has a nose for getting on a storm. I honestly think we caught a tornado 75% of the time back when I chased with him years ago. Will never forget some of those early chases. To see what Brett has built and accomplished over the last 15 years is absolutely amazing. He had the passion and desire and he took that and built something that very very few people are capable of.

This is over stimulating, this will be something that will be written in the history books.

I can't even keep track of everything, end of story.

Now confirmed.

I don't know much about ingredients and parameters but it makes me wonder what is making up for the modest temperatures and dewpoints. It makes me me think of the Tri-State 1925 tornado but that occurred in mid March. We are in late April.

There is plenty of dewpoints for this event! Low to mid 60s dewpoints all the way into Iowa

the whole meso is on the ground

At least there have been no confirmed fatalities and I hope it stays that way.

Knock. On. Wood.

This is what happens when you have low LFC and steep lapse rates to go along with extreme kinematics and favorable storm mode.

Something all previous events this year lacked, as you can see, quite the difference.

I seen 63.0°F/61.0°F as Terramt, IA was taking a direct hit.

Minden, IA

I hope this tornado splits Defiance and Irwin.

The entire meso looks like it’s trying to sit on the ground.

Honestly appeared to be the case, I can't remember seeing anything like that since El Reno.

Brett is driving through damage currently.

Instability is not just about what is at the surface. It's 100% about the vertical distribution of those factors with height through the column of the troposphere. 500mb temperatures are -15C and colder in the supercell outbreak area up there. There have been instances in Iowa specifically with F3-F4 long-track tornadoes with surface temperatures in the upper 50s. Despite the surface observations as they are, mesoanalysis still shows 1500-2500 j/kg of SBCAPE nosing up into a good bit of southwestern Iowa and southeastern Nebraska.

The wall cloud is spinning like crazy. Can't tell if the circulation is all the way to the ground but I wouldn't bet against it.

The millionth pds tornado warning has now been issued.

 

[TornadoFan]

Am I seeing two seperate rotations on it?

PDS polygon issued to the N of the current TORE.

Manilla, IA may take a direct hit...
