PHOTOS: Unique Clouds Drape Georgia, South Carolina Skies

As Monday morning ushered in dark skies near the Columbia, South Carolina, area, onlookers were treated to a unique cloud formation that offered an unsuspected twist to a gloomy morning.

Known as asperatus clouds, the peculiar formation garners an extra glance at the overhead skies due to the appearance that simulates rolling waves.

"Asperatus clouds form on the outside of precipitation areas, where the rain attempts to invade dry air," AccuWeather.com Meteorologist Jesse Ferrell said.

The rare cloud formation can also appear deceptively ominous as the accompanying darkness and bulky shape do not always indicate a storm.

"There were showers and thunderstorms approaching the area from the west at the time," AccuWeather.com Meteorologist Alex Sosnowski said. "The air was dry near the ground but was increasingly moist aloft as the storms and rain approached."
