2011-04-14 NOW: OK/TX/KS

[Jason Bolt]

Might as well get this started. Sitting in Wellington, KS waiting for initiation. May drop south once things start to go. 78/61 here so it seems the juice is actually starting to make it north.

 

[Tim Marshall]

Sheared TCu in Pauls Valley. 63 dewpoint.

 

[Chris Herzig]

Just stuck my head out the door, tower going up just east of Luther, seem to be building slightly to the west

 

[James Langford]

First significant returns of the day are starting to show up just West of Ardmore. I would expect rapid development along the dryline within the next 30 minutes. SPC Meso Analysis shows a robust cu field all along the dryline, with a pocket of 3000 cape. Surface winds are backed nicely from the SE.

Looks like the dryline is lighting up all the way through NC OK and into SC KS as well. Explosive development within the last 20 minutes.

 

[Skip Talbot]

Looks like there is a 20 degree T/Td spread across much of the warm sector and northern OK and KS is really struggling to hit 60 on the dewpoints. That might keep bases on the high side and hamper tornado potential for at least the first couple hours with these initial storms in OK and southern KS. This should improve later when some of that better moisture in southern OK/TX advects northward and/or the surface temps cool down a bit later this evening. The entire OK dryline is lighting up explosively right now too. Hopefully the cells stay discrete long enough for that to be realized, otherwise storm mode might also limit tornado potential.

 

[Chip Redmond]

Dryline in N OK/S KS seems to be bulging eastward and therefore being right along the convective development. This could cause more forcing and create more linear development of storms while the southern storm in S OK is out ahead of it and seems like it will remain discrete.

The deeper moisture still appears to be about 30-40 miles ahead of the developing storms. The storm near Fairfax is showing hail but it might be cutoff from the storm to the south. The cell in southern Lincoln County looks interesting, has a nice flank and a hint of a notch, but I would guess most the rain is still aloft.

 

[Jeff Duda]

Shear in the immediate vicinity of the dryline is not very impressive right now in terms of being in a PDS tornado watch. Deep layer shear is certainly sufficient for supercells, but 0-1 km shear is below 15 kts and effective SRH is generally below 200 m2/s2. That will certainly increase towards 00Z, but at least as of right now, I don't see any of the storms becoming imminently tornadic in the near future.

Also, as Chip and Skip (lol) mentioned, the storm mode, especially north of I-40, appears to be in question. It could end up going linear pretty quick there. The dryline has hardly moved east at all south of about I-40. I bet the folks at OU are getting great obs on both sides of the dryline!

Sitting near stroud ok watching storm to the sw. Nothing too impressve yet and I'm beginning to wonder if this might turn into a linear mess.

 

[Andrew Stoller]

The texaschaser.com is streaming from the southern storm near Sulfur, OK. The storm has a huge RFD clear slot already and a large rain free base. Looks to be wrapping up quickly. There's been intermittent funnel clouds as well.

:edit: Randy Denzer is right under the base of the Sulfur, OK cell. It's spinning like a top! When the stream stops for a minute and catches up, the rotation is intense!

:edit2: Rapid rotation with a collar cloud from the texaschaser.com stream. Looks like it might produce on this cycle.

I'm at the Walmart parking lot in Sulfur, OK watching as funnel clouds are appearing.....nice rain-free base

Tornado about to happen Maybe on that Stream
