Chase Case #1

[Dann Cianca]

Hopefully I'm not seeing garbage on radar in the middle of this cu field, but I'm heading north out of Hebron, NE to York, NE. Was very close to pulling the trigger and heading east-southeast, but I'm going to stick with my initial target area.

 

[Brandon Jenkins]

Well after sitting here in Tonkawa all day it looks as though I'll finally have to make a decision on moving north or south. I can see an isolated tower going up just to the north of the Kansas border so I will head towards Wellington, KS and monitor the situation as I go.

 

[Scott Hammel]

Brandon is right, time to get out of Tonkawa. I'm going to head S though and drift down to Guthrie, OK where I can hopefully intercept some of the southern cells as they mature more. That storm up near Hiawatha is massive and I'm hoping the southern target will pay dividends as well!

 

[Connor McCrorey]

Looks like I got a tornado near Hiawatha! No complaints here

 

[Andrea Griffa]

I know this case, I'm out.

 

[Bob Hartig]

I'm in southeast Nemaha County tracking with the second of the two NE Kansas supercells. Wish I could say I was on the first, tornado-warned storm, and maybe I would be in real life, but I'm going to be hard on myself for not instantly jumping on it when it was severe-warned. Not too hard, though. This second cell has great inflow, and I see no reason why it shouldn't produce. It has roughly 35 miles to do so before it hits the river, and it's not moving as fast as I'd originally expected. Meanwhile, other cells are developing down the line, so it's a matter of seeing what happens and choosing my options.

 

[Verne Carlson]

Cells in central OK are moving my way at 30mph - I'm dropping south closer to I-40 west of OKC to intercept.

Strong to severe thunderstorms continue to rapidly develop across the C and S Plains. A couple tornadoes are already confirmed. My last update may yield huge dividends for those of you in S KS or NC OK!

LAST UPDATE: 23z-end. Sometime tomorrow. Final surface obs/upper air data/etc will be available tomorrow at 23z

 

[Andy Jackson]

On the Butler county severe storm this should get going, if not I will try the ones to the south.

 

[Bob Hartig]

Nice to see that my storm here in northeast Nemaha County is tor-warned. Also nice to have options on the next one to my southwest in Pottawatomie, also warned. All of these storms seem to have no constraints on their appetites for nice, juicy inflow. Supercell buffet here in northeast Kansas!

 

[Patrick Martin]

Going on the assumption that the cell near Manhattan was the one that came up from Lindsborg, I met up with it outside of Junciton City, and trying to keep pace with it as it moves northeast. Hoping my patience in holding in the Salina/Junction City corridor thru the day pays off!

 

[Dann Cianca]

Danny, could we have 22Z or 23Z surface obs? Haven't seen any for a couple hours worth of the case here. Thanks!

 

[Danny Neal]

I posted 2130ishZ obs yesterday in an edited post in my 21-22 update, not sure if you caught that so I posted the 2130Z obs again the next obs I have are for 2315Z. I know of a site to get 22Z if that is what you want.... give me a minute and I will post it.

ALL:

 

[Jeff Duda]

Caught in the crap near Junction City, KS. Hopefully something comes out of it.

 

[Connor Keef]

After driving 2 hours, I've reached the Comanche Co. Storm. We'll see what it brings
