Unique lighting late one April evening led to a striking photograph taken near Greensburg last month by Dillon Killoren.
Shelf clouds are commonly seen on the leading edge of squall lines, and are often the source of false tornado reports called in by people unfamiliar with meteorology. Why? Because they can look pretty scary – as this April 18 photo shows.
But that’s all they are: scary-looking clouds.
Nevertheless, they can signal the approach of storms that can deliver strong winds and some heavy rain.
