Meteorologists in Norman said that they saw a crowd of rainclouds over western North Texas. It was later found that these were not clouds, but a swarm of bugs. Grasshoppers and beetles were flying between the ground and 2,500 feet in the air covering a 50 mile area.

Experts said that the swarms were so dense that it appeared on the Doppler as there was bad weather in the area making meteorologists confused as they have predicted clear, sunny skies. Jonathan Kurtz, a meteorologist at the Norman Forecast office, said that they thought that it was a kind of biological feature.

The swarm in the sky was not visible as the bugs were flying at different elevations. "It doesn't take a whole lot of bugs to cause that on radar. It was not like biblical proportions. There was just enough out there that the radar picked it up", said Kurtz.

Ari Sarsalari, a forecaster for The Weather Channel, said that such scenes are not unusual. Such incidents keep on taking place in the Upper Midwest and the Mississippi River Valley at the time of spring.

Sarsalari said that similar thing was even reported in south central Texas near New Braunfels. The weather service officials said that people became quite concerned to see bugs, but they tried to pacify them that nothing is wrong.
