GRL3 showing some heavy rotation on the Marlow, Oklahoma storm. A TVS marker just showed up on my radar, and looks pretty legitimate.

**EDIT: I see that Bob's post had the jump on mine as I was observing and typing. To add to the observance, the radar has dropped the TVS +5 minutes after this post, although the storm still seems to keep trying to attain a nice hook.

best rotation on Duncan, OK storm is still aloft. Best looking structure so far today. but environment just isn't great for long lived classic supercell.

The storm near Marlow OK is looking pretty nasty now, and has a TVS marker on it in GRL3.

Yep, I was sitting on highway 7 just east of Lawton watching the line develop to my NW when this cell exploded just a couple of miles to my west and just ahead of the line. There was noticeable broad scale rotation in the updraft, but I've given up on it cause it's racing off to the east at 45 mph and I'm going to see if these cells behind it will do anything.

 

[James Aydelott]

those cells behind it don't look good at all, kind of a linear/multicell look on radar so far.

The cells along the cold front are elevated if I can compare Mesonet obs and 88D returns correctly. Although the supe east of Lawton (Duncan) looks great on 88D those are mid-level returns. Low-levels probably look real gusty as it is being undercut by a rather slow moving cold front. If it can turn southeast (which it will not) it could become more surface based, but otherwise it looks to be a good hailer along with overall great mid to upper level structure.

EDIT: Most recent return confirms, gusting out.

 

[James Aydelott]

it looks like the Lawton convection is seeding the Duncan storm right now, might help explain the thing looking a little less classic supercell on radar. Still, the Duncan storm looks decent.

That storm does have a nice appearance, but I'm not seeing any rotation below 10,000 feet. If I were chasing I would hope this storm would pick up it's speed and take a little jog to the right so it doesn't get overtaken by the CF. Seems to have been trending down the last few scans.

As James astutely noted, that storm is in a bad environment. Sfc and 850 winds are nearly calm, and CAPE is practically nothing there. In fact, Pauls Valley to the ENE reports 66/53 with NNW wind @ 7kts. That could be due to earlier outflows, but even Ringling to the due S reports 67/65, SE@4kts.

I'm sitting in south Duncan right now, but it's not looking good...storm motion today has been a killer, heck the cell in front that was looking nice near Marlow is already almost to I-35!! And yeah, when I could see it early on it was quite elevated.

 

[Darrin Rasberry]

The storms near Lawton do indeed appear to be spiraling downward atm, but they are continuously developing over the area and might choo-choo some heavy precipitation near the Wichita Mountains. If this trend continues, I would not be surprised to see a flood warning nearby.

I am also looking at a storm nearing Little Rock with rotation/TVS, but it is hard to observe fully due to the ground clutter at KLZX and, in addition, the nearby KSRX not returning a feed to me.

Probably the storm of the day in AR right now

 

[Nick Parker]

Another wonderful shot from GR3....

 

[Chad Cowan]

Benton, AR is in trouble... and there isn't a whole lot of competition for this cell so even Little Rock could be under the gun here shortly.

 

[Danny Neal]

Rotation has tightened up considerably, all though the storm is looking a little blotchy....

 

[Jordan Hartley]

Sure is alot of junk that fired up and got sucked into the storm. We do have a nice looking sig here but I would be surprised if we do see a tornado with this storm. It looks like crap. Just seems like its starting to breakdown a bit. Any reports yet? There is a very nice mesocyclone with this storm.

Do we have a donut hole with the storm over Benton? Cant tell with NWS radar.
