6:07 CDT at the Vona exit along I-70.  Developing severe storm in W. Kit Carson County.

 

7:25 CDT stopping location on US36, one mile east of US385 (5 NE Idalia).  LP storm beginning to take on meso appearance to the WNW.

7:30 CDT same location.  Storm is getting better organized into a LP supercell.

 

7:30 CDT.  Overturning convective "knuckles" on the backsheared anvil.

 

7:40 CDT.  Funnel cloud beneath the high base of the meso.

 

heading north on SR27 northwest of St. Francis, KS.  Meso is showing very pronounced banding in the lower levels.

 

heading west on SR27

 

8:20 CDT stopped along westbound SR27.  Impressive updraft with low level banding and pancake-shaped backshearing anvil.

 

8:36 CDT heading back north on SR27, just south of the NE border.

 

8:45 CDT stopped along SR27 near the NE border.  Incredible LP supercell with pronounced mid-level inflow bands, somewhat of a corkscrewing updraft, and overturning convective knuckles under the backsheared anvil. 

Just above the low/mid level circular banding appeared this wispy filament "thing" (for lack of a better term).  A NWS met from the Goodland office saw my video of this and considered it a unique sort of mid level funnel.  I put it in fast forward to notice any rotation, but there only appered to be little rotational motion if any at all.

A closer look at the backsheard anvil of this storm, with pronounced overturning convection.

 

Precip shaft from the RFD develops in the middle of the meso.

 

Heading north again on SR27.  Don't be fooled, this is not a large wedge tornado, but rather a confined region of heavy precip in the vicinity of the meso.

 

8:58 in Haigler, NE.  Mesocyclone really begins to take on a classic "mothership" shape.

 

9:02, north of Haigler, NE.  Northern portion of the mesocyclone, looking west-northwest.

 

Precip is still falling from the RFD region of the LP meso.

 

Incredible inflow banding.  Four "tiers" of banding made for a simply awesome mesocyclone structure.

A look at the mid level region of the mesocyclone.

 

9:05, Zoomed in at the base of the meso where a concentrated region of precip was falling.

 

The mothership has landed.  The inflow banding on the southwest portion of the meso creates a sureal scene right out of the movie "Independence Day."

More overturning convection building downward, with lightning on the bottom left portion of the image, in the vault region.
