Severe thunderstorms can produce hail an inch or larger with wind gusts around 58 mph. Hail this size can damage plants, roofs and vehicles. Wind gusts can break off large branches, knock over or cause structural damage to trees. Occasionally a severe thunderstorm produces hail that is the size of a softball with winds over 100 mph. They also can produce tornadoes, dangerous lighting or flash flooding.
