A Rain Curtain - or a Precipitation Shaft (to use the official meteorological term), is a weather phenomenon, visible from the ground at large distances from the storm system, as a dark vertical shaft of heavy rain, hail, or snow, generally localized over a relatively small area. For some reason, I'm crazy about them. I think they are so beautiful! The Rain Curtain seen here is falling over New Jersey.
