Key moments
On March 19, 2018, northern Alabama experienced a significant weather event when supercell thunderstorms produced hailstones larger than grapefruit, marking the state’s first official hail record. The National Weather Service reported a hailstone measuring 5.38 inches in diameter and weighing 9.8 ounces, a stark increase from the previous largest known hailstone in Alabama, which measured 4.25 inches.
In addition to Alabama’s record, a six-inch hailstone was reported in Kankakee, Illinois, which could potentially break the state’s current record of 4.75 inches set in Minooka in June 2015. These developments highlight the increasing severity of hailstorms across the Midwest and South.
Hail can pose serious risks, damaging aircraft, homes, and vehicles, and can be deadly to livestock and people. The formation of hail occurs when raindrops are lifted by thunderstorm updrafts into extremely cold areas of the atmosphere, where they freeze together. Supercell thunderstorms are particularly notorious for producing large hail due to their sustained updrafts that repeatedly lift hailstones into very cold air.
Historically, hailstorms have caused significant financial damage in the United States, with a handful of storms resulting in over $1 billion in damages. The costliest storm recorded was on April 10, 2001, which resulted in property damage exceeding $2.5 billion in 2018 dollars. Such statistics emphasize the potential economic impact of severe weather events.
Before the March 2018 storm, Alabama had no recognized official hail size record, indicating a lack of historical data regarding severe hail events in the state. This recent record-setting event may prompt further research and monitoring of hailstorms in the region.
As communities in Alabama and Illinois assess the damage caused by these recent storms, officials are urging residents to remain vigilant during severe weather events. The National Weather Service continues to monitor conditions and provide updates on any further developments.
Details remain unconfirmed regarding the full extent of the damage caused by the hailstones, but initial reports indicate significant impacts on property and infrastructure. As the situation develops, further assessments will provide clarity on the aftermath of these record-breaking hail events.
