September 6th, 2007 South Central Nebraska Supercell
Last Updated on Monday, 04 January 2010 21:38 Written by Roger Hill
Good shear, great moisture and instability, and a boundary would set the stage for severe storms in Nebraska September 6th. I headed out to my target of Lexington, NE and arrived by mid afternoon. Cells tried and tried to form, each time getting choked by the cap. Finally early evening, several supercells formed. The storm shown above was tornado warned and at times ther appeared to be funnels back in the notch of this HP. One time a cone shaped funnel extended halfway to the ground, but I could not confirm any tornadic touchdown. We did encounter hail golfball size with this activity.

Initial storm forms and was high based. It later obtained better structure, but we blew it off for activity south, just ahead of the boundary. |
Second supercell looking south near Holdridge, NE. This storm produced ping pong ball sized hail. |

Third supercell which was the grand finally near Oxford, NE! This was taken with a 10 MM lens to get the whole scene in. There was a lightning strike under the north side of the updraft. |
27MM shot here. Notice the block wall cloud under the updraft on the right side. We are looking southwest. Inflow had picked up to about 20 MPH now. |
Another wide shot of the magnificant structure! |
Near Franklin, NE at 8:45 PM. Taken with 3 second exposure, 800 speed, F4. Storm was tornado warned here still. |
