6.2.02 Mule Creek Junction, WY

A supercell developed west of Mule Creek Junction, WY and slowly headed east. It passed 1/4 mile north of the junction showing persistent base level rotation and cyclical intensity. The storm became more linear as it continued eastward towards Hot Springs, SD. North of Edgemont, the storm rapidly re-intensified and produced golfball sized hail and intense lightning as it moved into Hot Springs.

	North of Mule Creek Junction looking west-southwest.
	The updraft base became circular indicating some base level rotation.
	Notice the tail cloud that feeds out of the storm from the right and reenters the updraft to the left.
	Now at Mule Creek Junction, here is what the wall cloud looked like as it approached. It was rotating, but not very fast.
	About 1/4 mile away. The wall cloud was hanging only 100-200 feet above ground level.
	Rear flank outflow winds reached 40 mph before I headed further east.
	This was the picture right before encountering golf ball sized hail. Notice the precip core to the left and an a lowering in the middle of the picture. This image was taken looking west from an elevated vantage point about 5 miles southwest of the highway 18/89 junction.
	My car received about 50 dimples from the 10 minute long barrage. Most of the hail was dime to marble size, however the golf balls occasionally made themselves known with an "enhanced" thump. My anemometer received a fatal blow breaking the shaft to the wind cups.
