07/07/04 NOW: Central Plains, East Coast, Canada

[Larry J. Kosch]

Starting a NOW thread for 07/07/04 due to severe weather firing up in different places. A SWW watch has been posted for NE and KS. There is already a supercell storm crossing the NE-KS border near Superior NE into Jewell County in KS. There is a SWW watch set up for the East Coast. And I understand there is storm action firing up in yonder Canada. Post your storm discussions here. 8)

Update: TORN warning in Jewell County KS:

Supercell moving SE

That supercell storm in Jewell County KS is moving SE into Cloud County. Looks to me it will brush just to the west of Concordia KS. It had just engulfed two smaller storms like they were bait fish!! :shock: Better keep an eye on this storm while it's getting organized for tornadic action! 8)

Interesting that the maximum length of a Tornado Warning is 45 minutes yet both of these are over an hour, guess some offices can write their own rules.

Oh wait - wrong thread ;>

Supercell in NE?

Don't look now but there may be another supercell brewing in NE! :shock: There's a nice storm shaping up super-cell like in Seward County in NE. It's blowing its way thru Seward NE right now and heading SE into the SW corner of Lancaster County. If that sounds familar to some of you storm chasers, it should. Hallam NE is located in that corner of that county!!
Let's hope we don't get a repeat of that tragic day back in May!! :shock:

Update: Opps! Spoke too soon! It's already outflow dominant and in the process of collasping. Sorry about the false alarm.
It did look circular and strong for a bit... I'll shut up for the rest of the afternoon!!

"a nice storm shaping up super-cell like in Seward County in NE."

I'm not sure I understand - it either is a supercell or it isn't, I'm not sure how a storm can be "like" a supercell?

Similar to a Skywarn spotter report from yesterday here in Lansing - "I see a funnel cloud rotating overhead, it doesn't look like a funnel though."

Hmmm...

That tornado warned storm and its tennis ball sized hail is making a direct line for Salina.. :shock: Heads up to that interstate town!

 

[Larry J. Kosch]

KS Storm now a dying swan

That supercell storm that dropped hail and a brief tornado in Mitchell County KS is now doing a "dying swan" act. It may not make it to Salina KS before it drops off the radar screen. But goodness :shock: look at the line of storms firing up right behind that. :shock: It's streaching from Concordia to Hays KS and moving SE.

Just had a nice thundershower move thru Lincoln NE. Nothing to write home or get the storm chasers excited about. OK I said I would be quiet. Starting now... 8)

 

[mikegeukes]

Storm heading to Salina is basically no more.
Interesting to look at the radar animations of that cell.

I saved 3 animations from that cell

More thunderstorms have developed to the northwest of Salina.

Wow, that storm died in a hurry, didn't it! Sheesh! :shock:

 

[Robbie Cox]

This thread sure died quickly. they all must of jumped in the cruiser and headed to kansas. :lol: since the storm doesn't seem to want to die.

Some towers started going up in W WV and quickly died. While I was out I had WxWorx running and decided to take a look at Kansas. The cells north of Hays have *nineteen* shear markers, massive cores, and big blobs of 'shear' maxed out on the Baron display. A few shear markers showed 138MPH values. Three counties are tornado warned. Looks nasty - and fun. Probably some spectacular structure and lightning with these.

0850 PM TORNADO 7 SSE BUNKER HILL 38.78N 98.65W
07/07/2004 RUSSELL KS TRAINED SPOTTER

CLASSIC CONE SHAPED TORNADO REPORTED ON THE GROUND.

 

[Jeff Snyder]

Per SPC mesoanalysis, those storms in KS are in an environment characterized by 3000-4000 SBCAPE and 350-500 m2/s2 0-3km helicity (yielding 0-3km EHI's ~12)... The boundary layer is beginning to stabilize due to the setting sun, so the convection will likely become increasingly elevated... However, if convection can remain surface-based, the tornado potential should continue as low-level shear and instability remain very favorable for tornadogenesis..

Given this, I'm not entirely sure of the lack of tornado potential in various discussions... Granted it'll hard to maintain surface-based parcel origins, but the environment is primed and surface-based convection has been occurring for several hours...
