A massive hailstorm shatters glass windows throughout the city of Philadelphia.
In the afternoon, a massive storm broke over the city of Philadelphia, Pennsylvania. The remarkable element of the storm was the massive downpour of hailstones, some reportedly measuring three inches in diameter. The so-called "Great Hail-Storm" was said to have broken up to half a million panes of glass in the city. (By John Osborne)
