A shortwave moved across western and central Wyoming on the afternoon of June 27th. There were very large dew point depressions that led to the formation of high based thunderstorms. These thunderstorms led to many severe wind gusts, some of which produced damage. The hardest hit area was Worland where wind gusts as high as 69 mph blew down many trees and power lines. In Natrona County, a pine tree was blown over on a car in downtown Casper. Reports of wind gusts of 59 mph or greater were also reported in Big Horn, Fremont, Hot Springs Counties and Johnson Counties. In Yellowstone, a lightning strike damaged 2 cars.
