The pilot first contacted the air traffic control tower about 10 miles southwest of the airport. He was instructed to enter a left traffic pattern for runway 23, and informed that the winds were from 330 degrees at 10 knots. While abeam the threshold on the downwind leg, he was cleared to land, and informed that the winds were now from 340 degrees at 7 knots and the wind velocity had increased to 18 knots. The pilot then requested to enter a right downwind for runway 30, which was approved, and was told that the winds were now variable from 300 to 030 degrees from 10 to 18 knots. While on final approach for runway 30, he was informed that the winds had shifted to 020 degrees at 15 knots. The final wind check before landing indicated that the winds were from 030 degrees at 16 knots. The aircraft touched down and bounced then veered toward the left edge of the runway. The pilot stated that as he attempted to correct for the left drift, the right wing rose up and the aircraft crossed the runway in a right arc on the left main wheel and ground looped at the right edge of the runway. He further reported that approximately 15 miles southwest of Elko he had noticed lightning coming from a cloud 2 to 3 miles northeast of the airport. He also stated that about the same time, an airplane that had just departed reported that they were experiencing major updrafts and downdrafts east of the airport.
