6/6/07 NOW: ND/SD/NE/KS/MN/IA/MO

[Kory Hartman]

Cumulus Puffs going up now west of Presho... cannot see it on Visible Satellite yet. We are going to continue west to Kadoka for now, but looking for new development ahead of the front.

Live Streaming ChaseCam is working great, if you want to watch traffic on I-90. Tons of construction from Chamberlain to Presho. Really slowed us down.

Good job to everyone on the Tornado in Shannon County.

Both the 21Z RUC and the 18Z ETA break out precip in C NE after 0Z now, still sitting just east of the DL trying to talk myself into leaving but might as well wait and see, definitly was banking on better then the upper 50 DP's.

The storm in NE Shannon Co, SD doesnt seems to be moving very fast, at least not the precip core. Other cells from NW Nebraska moving into SE Shannon and Bennett Co, SD seem to be moving at a much larger pace and have a rotating mesocyclone somewhere embedded in all that mess. I wonder how the 2 tornado warned cells are going to interact with each other. Something is really coming together in Shannon Co. and anyone on this storm needs to keep your head on a swivel.

Starting to see developing cu on vis sat with pockets extending all the way down to NW KS. I think the big show is fixing to happen in SW KS. The RUC seems to have precip breaking out in the next hr although the cap is pretty stout up to 4000 j/kg. Supercell composite up to 20 with sig. tor up to 3, sfc winds backing slightley out of the SE in Meade Co.

 

[Paul Knightley]

Towering Cu seem to be developing along/behind the dryline around SW NE...I would expect at least one of these to root into the moisture east of the dry line, and perhaps become a supercell across cent NE.

 

[Jeff Snyder]

Sitting in BBW after stopped our NWward progress. Per LNX radar data, it looks like the north side of the dryline bulge (the e-w dryline part) is moving northward around 30-35-40mph, with the cold front moving eastward at 35-40mph (my guestimates). With this, we feel we won't be able to catch up with this apparent triple point easily. Latest 21z RUC and 18z NAM show initiation in sw NE in the 00z-03z period, and current vis satellite shows towers developing on the dryline between McCook NE and Colby KS. We may actually stay here and head sward should that look like it's initiating..

Still wouldn't be surprised to see a massive supercell down in southwestern OK and eastern OK panhandle. Shear is very strong, and convergence appears to be increasing. Temps near 90 should put it w/in a couple of degrees of convective temp. Good 67-70F tds streaming into southwestern OK as well, heading northward. The irony of OUN'ians in NE busting while a supercell develops in sw KS or thereabouts.

 

[Kory Hartman]

New Cell forming near Presho, SD. We are south of I-90 a little bit watching the storm develop. Looks like a good updraft and we had a small lowering for a little bit. ChaseCam is up and streaming... but it is still kind of gray for the camera to pick up.

 

[David Wolfson]

The Pine Ridge/Kyle storm is now approaching Philip. It appears to have become congruent with the surface low and even pinwheeling on radar, to my eye. Thus the more northerly track. The experts may know whether this makes it more or less tornadic; for me it's theoretically very interesting. FWIW.

 

[Dan Robinson]

Still holding tight in Grand Island. Too many critical things fell apart today. Early on, I never could talk myself into going farther west or north given the eastward haul we have tomorrow. Triple point obviously was the play, but I just didn't want to go that far. So instead, we've spent the day documenting the crazy mini-haboobs everywhere. Pretty impressive sights and enough to be a 'consolation prize' for the day. We did manage to damage my driver side door by accidentally letting the wind slam the door open into a parked car at Wal-Mart. No damage to the other car, big dent in my door.

Like others, we're watching the Cu field to our west - but not with much optimism. My pessimism is evident by the fact that we've already got a hotel room for the night here. Unless something compelling develops within reach, we're crashing early to get ready for tomorrow.

Unfortunately I had to sit this one out, but that won't stop me from virtual chasing here from home. I like your position in Broken Bow Jeff. I am originally from Lexington, and thought this forcasted sounding and hodograph from the 3Z RUC was very interesting:

The supercell potential, CAPE, LCL, LFC, and shear profiles would make me want to plant myself smack dab in the middle of Dawson County around 9 pm tonight. Good luck to everyone and be safe, especially after dark.

Check that... I meant to say we are south of Murdo, SD. Possible wall cloud trying to form. Lots of up and down.

Come have a soda with us, LOL -- we're sitting at the soda shop down the street from you. Waiting on same hope that you're waiting, though there also seems to be a rather large OFB tearing down through NW NE, just about to cross over KLNX. We're kinda curious what's going to happen when the OFB meets up with the retreating dryline.

There actually was a bit of cumulous/turkey towers trying to go up SW of BBW here, but they've been slapped down again and again by the cap.

 

[Jeff Miller]

Possible NE initiation NE of an Imperial to Ogallala line in NE. SOmething to keep an eye on to see if they root or if the cap kills em off.

EDIT: Anyone else fascinated by the converging boundaries??

 

[Tim Jones]

Anything initiating in the Ogallala, NE area right now would be behind the cf/dryline . . 77/41 NW25, G35. To the NW, Thedford (TIF) is SSW 88/36. Quite the dry punch working thru in SW Nebraska.

 

[Josh Murfield]

Tornado watch now out for central and NE Nebraska reaching as far east as O'Neill and Grand Island, storms are starting to fire in the westcentral parts of the state.

 

[Dustin Wilcox]

I am just East of broken bow on 183 can see the TCU to my SW however attm it is not all that impressive.
