04/09/09 NOW: OK, KS.

[Rocky Rascovich]

From the farm northwest of Piedmont, OK. Congestus is developing very rapidly to my northeast over southern Logan Co. and this verifies on satellite.
Winds are now gusting to about 40kts here at the farm from the SSW.
DL appears to be in far eastern Okla. Co. on north into Logan Co. where some moisture convergence is likely causing the congestus growth. You may want to keep an eye on these developing cells even though they are not surface based yet.. I'm wondering if it will struggle initially because of the EML, but lapse rates may overcome this.

NEW Storm Stillwater

I see exploding Towers west of tulsa also on radar. Here we go.

Dryline is very impressive on radar.

First echos popping up over Northern Payne County and starting to develop just southwest of Chandler.

 

[Rocky Rascovich]

Just got off the phone with Charles Edwards who excitingly reported a distinct laminar funnel cloud extending out of the side of a base of congestus that developed over the north end of Shawnee as of 1415cdt. He said it persisted for about 5 minutes and had definite visible rotation. Cloud base was probably 4K feet at least based on LCL's. This may be an ominous sign for later today.
DL is moving into Shawnee now. I'll be frequently observing this event from the computer as I had stuff to do around the house, so no chase for me today.

 

[Chris Vagasky]

I would be keeping an eye on this cell popping up near Chandler as it advances towards Tulsa. Appears to be going up with some mid-level rotation.

Quite impressive from the TDWR sites even displayed on Wunderground:

Looks like we've got our first supercell of the day. Between Stroud and Cushing. Moving to the NE.

 

[Chris Hayes]

Though small, the storm NE of OKC is going up nicely and has some supercell characteristics to it. Nice that it's so close to I-44. Be pretty easy to follow it toward Tulsa.

 

[Chris Vagasky]

I think, but I'm not sure, that Jeff is on the storm just E of Cushing. Looks great on video.

 

[Jeff Duda]

Storm crossing the OK/KS border just SE of Wichita looking more and more impressive with each scan. Now showing clear mid to low level rotation, and the NROT product on GR2AE is showing negative values over 1! Could we have an anticyclonic supercell on our hands? We shall see.

Interesting storm motions as well. The one north of that cell is moving North-North West.

 

[Jeff Duda]

Yeah, I wouldn't think those are going to make it much farther if they keep moving to the north there. The warm front isn't too far north of Wichita. By the time you get up to Emporia, Tds < 50 and T < 65, so instability will begin to really cut off for these storms.

 

[John Farley]

That cell northeast of Ponca City is looking very impressive on radar and just got a SVR. Looks like it is right on the dryline, and not far from the triple point.

 

[John Farley]

I was wondering if some of that stuff showing up on radar behind the line of storms might be wildfires - especially that return southeast of Enid.

There is a massive wild fire that might cut off 44 heading to Tulsa. The fire was really, really close to the road when we went through it. Massive amounts of smoke and visibility was incredibly low through the area and you could literally feel the heat through the car. I believe it was mile marker 156. Just warning those chasers out who might be leaving late.

If anyone is still in SC Kansas I'd be getting to Kingman-Cunningham-Pratt area post-haste according the DDC shortfuse composite. I'd say you have less than an hour, but parameters are overlapping nicely in that region.
