1995 Mayfest Storm : ウィキペディア英語版 | 1995 Mayfest Storm The 1995 Fort Worth Mayfest storm was a supercell storm that occurred on the 5–6 May in the Fort Worth and Tarrant County areas of Texas. It affected a highly populated area with hail up to in diameter, as well as striking the local outdoor festival known as the Fort Worth Mayfest. At the time the storm was the costliest hailstorm in the United States history, causing more than $2 billion in damage. The hail injured at least 100 people, and flash flooding and lightning from the same storm killed at least 13 people. ==Causes== The cause of one of the most destructive hailstorms in recent history was a high precipitation supercell which developed suddenly ahead of and near the crescent of a fast moving bow echo. The supercell died as quickly as it formed when it was engulfed by the advancing bow echo. The upper air sounding from Fort Worth that evening showed a perfect environment for high precipitation storms with sharp directional shear in the lowest layers, somewhat weak mid-level winds, and strong upper level winds of 60-70 mph.
