- This LP (low precipitation) supercell storm is small but dynamic
- W023079Z
- The combination of extreme instability (rapid updrafts) with high vertical wind shear (rapid downwind venting of cloud aloft) creates a low-precipitation supercell. The storm is small but very dynamic and energetic, often producing tennis or baseball hail ahead of a tall, rotating updraft column, sometimes with stripes in its outer edge (“barber pole”) as here.
