Hail storm in St. Charles / St. Louis 5/11/2016

Hail storm in St. Charles, Missouri (west St. Louis) with grape, clementine, golfball and baseball-size hail. This view is looking to the North. Just before this the sky got very dark grey, almost dusk at night, and slightly sea green to the West (left). The constant sound/rumble you hear like loud traffic or a train at the beginning is how load the storm was as the clouds came in before any rain, wind or hail.
