High Precipitation (HP) Supercell
very heavy rainfall, possible large hail, downbursts and tornadoes

In this photograph, the typical HP storm visual appearance is present: beaver's tail inflow bands curling into the front-flank updraft, a gray area of anvil precipitation to the north, and a dark rain and hail core to the southwest, falling from what earlier had been the rain-free base.

In the HP stage, this storm produced large hail, gusty winds, and extremely heavy rainfall, as well as several funnel clouds. One of these is visible where the inflow bands intersect the updraft. Continuous lightning occurred with this storm, much of it in-cloud, but a sizable percentage being cloud-to-ground strikes. Indeed, HP supercells seem to be especially prolific producers of lightning.
