New storm going up on WF 20 NE of Columbus NE.

Also the DL from GRI area SW to SW/OK looks like it will pop also.

The cin is below 25 now across NE along and south of WF cape 2000-4500 range.

The WF runs from 25 miles South of Sioux City to Columbus NE to 20 North of GRI where it intersects with DL.

Also cin below 25 along DL from GRI-SW/OKLA.
 
Not quite sure that's a storm yet - I'm not getting any lightning and there's not much to the cell. Good area to watch, but little towers have been popping up in that area for a while now with no growth. The OMA sounding I just plotted in the FCST thread still showing mid-level warmth.
 
It started to fade out but now the tops are getting higher and its getting its act together, still keeping an eye on it near Dodge. New MD came out from the SPC so a watch should be coming out very soon.
 
Jeff, I just did a cross section of that sucker in GR2AE, wow, impressive precip cores up to 40KFt, and a nice overshooting top developing...
 
Sitting in Harlan, IA at the moment. Wondering if that storm east of Norfolk is worth going after, or if I should be waiting for something a little farther south to finally go up. Tornado watch should be going up soon...
 
Im in Pratt ks heading south. The tower from the cell s of coldwater, ks is huge. other serious towers going up now on the dryline west of Pratt
 
sitting just east of decatur, ne, south of the first cell that went up. inflow has picked up dramatically over the last 5-10 minutes gusting probably close to 40 mph. seeing the back of the storm now but base seems kindof high. debating whether to keep following it east into iowa or go after the next cell that has formed near madison, ne and went severe warned a lot faster..
 
The 2nd cell that went up near Norfolk, NE is in a seriously mean environment. Supercell composite of 28, 3KM EHI is 10, significant tornado is 5, and 3km helicity is at 700. I hope someone goes after that sucker.
 
There looks like ground rotation and dust underneath the cell in the NE/IA border on some of the live streams right where the RFD is cutting into the updraft!
