6/19/07 NOW: KS,TX,OK,CO,NE

[Blake Michaleski]

MCD 1196 just issued. Watch to be issued shortly.

A very classic looking supercell has formed NW of Hill City, KS. As evident on the 1608Z-1807Z KGLD 88D loop, the storm is deviating quite significantly to the right.

Meso has tightened up on last scan (1837Z) with this storm. An inflow notch has also developed on the southwest quadrant. Storm should intensify as it moves south or even southwestward into more unstable air.

 

[Brian McKibben]

Tornado warning issued now on that storm. I would expect motion to continue in a S motion.

 

[Chad Cowan]

That cell is all by its lonesome... it has had a meso marker off and on for quite a few scans and just as I am typing this, it took on a TVS. There was a psuedo-hook echo present for a few scans but it appears to be about to ingest some convection to the south.

~4000 j/kg Surface Based CAPE
~2500 j/kg Mixed layer CAPE

A tornado warning has just been issued on the storm west-northwest of Hill City, based on radar.

At 2:18 pm...funnel cloud reported near Studley, KS by trained spotters with this storm.

 

[Kiel Ortega]

SHAVE is calling into the area (E Sheridan Co and also called on the first storm in NW Graham)...motions are slow and leading to 20 min. worth of hail fall time. Largest yet has been golf ball sized.

 

[Chris Hayes]

We're just north a storm that has formed south of Lamar Colorado along the dryline. Had a large overshooting top on it about 20 minutes ago and still has a smaller one. Trying to figure out if I should intercept this one or go east into KS hoping to intercept something up there.

 

[Chad Cowan]

Tornado reported @ 2:36 by law enforcement and 2:39 by trained spotters. I can't wait to see Laura Heiden's pictures of this storm.

Kiel, I was seeing VIL's consistently > 80 with the highest being 89 kg/m2... are these values so high because the updraft is almost completely vertical with the storm motions being so slow?

Dunno...maybe....VIL is generally calculated in a "cell-based" fashion...that's where segments of reflectivity are found and then the integration is performed. I would guess VIL is high b/c the storm had 55+ dBZ through the whole thing.

Anyways, just got a measured baseball report on that storm...poor people, had ~35 min of hail fall and then a 10 min break and then another 10 min of hail.

Your storm just went tornadic. I hope you hadnt left it yet to head to kansas.

* AT 155 PM MDT...LOCAL LAW ENFORCEMENT REPORTED A TORNADO. THIS SEVERE STORM WAS LOCATED 3 MILES NORTH OF PRITCHETT...

It is getting into the radar hole between PUB/AMA/DDC so it doesnt look like much on GR3 but I am sure in person it is great.

 

[Chris Hayes]

We're closing in on the storm now. Has a large backsheared anvil to it. How is the environment looking for this storm for the next few hours? About a half hour away from intercept

As this storm moves SE it will go from cape of around 100 to 5000 and LI's f -2 growing to -10 near the kansas border so plain and simple it will not only hold its own but get into much more unstable air very soon. Stary with it. It should go nuts over the next few hrs!!

I get off work at 4pm and will be on the road heading north soon!

 

[Michael Carlson]

We are halling out to KS/CO border right now getting on I-70, going to play the OFB and Dryline!

 

[Jordan Hartley]

Surprised there isnt a tornado warning out for the storm in Lane Co, KS right now. Look like the rotation has increase over the last couple of radar scans. Storm motion still to the S maybe back building to the SW as more convection seems to fire on the SW flank. In the last 20 min it went from looking like a mcs mess to a huge supercell. Still waiting for at least a torn warning from this storm.

 

[Jim Tang]

Are there any spotters/chasers on that storm? I'm surprised it doesn't have a TOR too but perhaps the observations don't agree with the impressive radar signatures.
