Nocturnal Hail Drift

Runoff from heavy rain carried hail to this spot near a motel curb, where it floated into drifts. The largest stones were about an inch in diameter--barely severe by official standards, and not damaging to cars or windows seen. A fascinating variety of hail opacity can be seen despite the lack of variation in size. Also, the color shift between the white hail in most of the photo and the tan hue below actually is related to differential shadowing--brighter, closer white lights under a motel canopy are shadowed from the bottom hail by an unseen curb, leaving that hail in dimmer, redder light produced by sodium-vapor lamps of a parking lot.
