TORNADO

When conditions are right, a large severe weather system really can spawn several tornadoes in a single day. In other word, it is the occurrence of multiple tornadoes spawned by the same synoptic scale weather system. This kind of event is known as a tornado outbreak, and the National Weather Service (NWS) offers a list of the 32 biggest outbreaks on record.

In real life, tornado outbreaks are usually spread across a wide area, often several states. several tornadoes sweeping through one small town on the same afternoon is improbable, though not impossible.
