- A supercell with a dark cloud arc ahead of rain and hail
- W991822S
- A supercell with a forward side inflow (HP or high-precipitation type) has a dark cloud arc ahead of the rain and hail curtain. Outflow pushes forward, scooping up the warmer air which rises along a curved axis into the tight rotating updraft and mesocyclone at the front of the rain near the bottom of this view.
