Over the past week or so, hailstorms have beaten down parts of the U.S. and other parts of the world.  Maybe it’s social media and the ubiquitous availability of weather photos, but I can’t ever recall such an onslaught of hailstorms.

Let’s take a tour.

Because hail events are so highly localized and we don’t have long-term records, there’s no way to know if the past week’s hail episodes were unusual.  May is certainly the time of year to expect hail – as temperatures at the surface rise quickly due to ever-increasing solar energy while cold air – necessary for making hail – remains at high altitudes.
