DALLAS – Tornadoes tore through the Dallas area Tuesday, peeling roofs off homes, tossing big-rig trucks into the air and leaving flattened tractor trailers strewn along highways and parking lots.

The National Weather Service confirmed at least two separate "large and extremely dangerous" tornadoes. Several other developing twisters were reported as a band of violent storms crept through the metropolitan area, destroying mobile homes and forcing hundreds of flight cancellations at Dallas-Fort Worth International Airport.

There were no immediate reports of injuries.
