A thunderstorm is a storm that contains both thunder and lightning. These storms can produce flash flooding, gusty winds, hail, and even tornadoes. The southern part of the United States has the highest number of average annual thunderstorms, especially those states located near the Gulf of Mexico and the Atlantic Ocean.
Louisiana typically sees between 50 and 70 thunderstorms a year, depending on the location within the state. Parishes closer to the Gulf of Mexico experience thunderstorms more frequently than those located in northern portions of the state. While most of the thunderstorm activity is observed during the summer months, the passage of cold fronts through the state during the spring and fall can also spawn severe thunderstorms.
In April 1995, a devastating hail storm hit the Shreveport area during the early morning (1AM CST), with widespread reports of baseball (2.75") to softball-sized (4.50") hail in southern Shreveport. Many roofs, windows, and vehicles were damaged. Total damage was estimated at $50 Million.
