A weird-looking cloud sporting the colors of the rainbow appeared to many in the Dallas-Fort Worth Metroplex early Thursday afternoon.The cloud stayed in the southeastern sky for several minutes, but was obscured by other clouds at times. NBC 5 Meteorolgist James Aydelott offered one possible explanation, saying that the sun was hitting the cloud at just the right angle, similar to a phenomenon known as “sun dogs,” causing the colorful display. He also said he had never seen a cloud like this before.
