May 20th, 2005 Harding County, South Dakota Supercell
Last Updated on Monday, 04 January 2010 23:59 Written by Roger Hill
What a remarkable day this turned out to be. We were in O'Neill, NE overnight and decided to blast towards northwest South Dakota for what we hoped would be a nice high based supercell. And what a supercell it was! We spent some leisure time in Belle Fourche, SD waiting for things to happen. We spotted a tower to our north and blasted to the Buffalo area. When we arrived we witnessed a convective explosion!!! A gorgeous rock hard updraft formed and produced one of the most scenic supercells I have seen this year. This storm produced hail golfball sized and was tornado warned for two hours. We were witness to several funnels, but could never confirm any touchdown. Several times, the clear slot produced a nice wall cloud, only to be shrouded by rain and hail. Check out the photos below!

Developing LP supercell updraft. Great structure was already developing here.

What beautiful structure!! This storm was spinning like a top and provided ample photo opportunities.

Scud was rising to the base rapidly here. Notice the hail core developing to the southwest of the lowering. This came close to producing a tornado.

Had to get a shot of me in front of this beast.

Nice hook on radar with precip and hail wrapping around the west and south of the updraft base. It tried to produce a tornado here as you can see the developing funnel.
