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.
