4/29/09 NOW: TX Panhandle

[Chad Ringley]

Tornado Watch up for a good portion of NW Texas. Supercell presently in Haskell/Jones County with persistent and strengthening low-level couplet and rapidly improving storm structure. Shocked there isn't a Tornado Warning on the cell (svr is out for Haskell, but strong couplet is out of a warning polygon?!?)

 

[B Doss]

Also change the date. I'm heading SE now, to intercept the severe warned cells on HWY 84 between Post and Snyder,

 

[Adam Atkins]

Looks very HP (via radar) with a big old fat kidney bean signature. Inbound/outbound velocities are high so I am surprised they haven't issued a tornado warning. Looks like that cell is locked onto an outflow boundary from this morning's MCS.

If it was in Throckmorton county, it'd be producing

Yes, clearly suffering from some sort of keyboard typing issue.

Throckmorton, now that brings back some memories! Looks like it'll cross into the promise land shortly. Velocities have come down some and a new meso appears to be forming in far NW Shackleford County.

I too am pretty surprised that Huskell cell isn't tornado warned yet, as nice velocity couplets are present at low and mid levels. There are also two TVSs from time to time, but no TOR warning?

Dryline continue to mix eastwards and looks like its just near line from LBB-AMA attm.

Cell starting to appear more outflow dominant as it progresses E. SVR continues for Throckmorton County.

I was kind of surprised there was no TOR warning also, but then I noticed the Pecos cell to the SW just went TOR warned. *shrug*

 

[Andrew Stoller]

Might want to add KS to the title, as a big cu field has developed in southeast CO and will likely organize into a few storms into southwest KS northeast of a surface low near Lamar, CO

Love those stationary supercells with massive VILs! A classic far SW TX supercell. The storm in Throckmorton County is now completely outflow dominant.

 

[Chris Lott]

New tornado watch issued for parts of SW KS down into the TX panhandle. Cells are starting to fire in a clear area ahead of the dryline where better destabilization has been able to occur. Cells continue to fire in SW KS with more cells firing from Plainview over to Childress.

 

[Mike Smith]

Tornado watch issued SW KS, SE CO, Panhandles. Supercell near Syracuse, KS.

Other cells breaking out around CDS.

 

[Chad Ringley]

Cell in Hall County, TX is Tor warned, another very promising looking cell now in NE Motley County, TX.

 

[Jeff Snyder]

Cell in Hall County, TX is Tor warned, another very promising looking cell now in NW Motley County, TX.

This storm appeared to develop on the OFB, and it began rotating very quickly. The cell to its south may give it some problems however. KLBB radar is indicating that the Motley Co storm is splitting, and it actually looks like the anticyclonic member is stronger than the cyclonic member. The 20 UTC SPC mesoanaly graphics had >4 anticyclonic supercell parameter in this area, so a left-split may be able to maintain itself for some time. I'd be worry about this left-split interacting with the Hall Co cell an hour or two down the line. With temps near 80 F and dewpoints in the upper 60s from Clarendon southward, I'd be focusing on the OFB that looked to stretch southeastward from Silverton. A few West Texas Mesonet sites actually had ENE winds just behind this OFB a little while ago. Not sure why the Motley Co cell would be any worse off than the Hall co cell.

Yep, that cell in NE Motley Co. is splitting and the left split does have higher velocities, and isn't verring very far off from the cyclonic updraft yet.
