Can tornadoes be predicted?

While it is currently not possible to predict a tornado with certainty, organizations like the National Oceanic and Atmospheric Administration issue tornado watches and warnings to areas experiencing tornado-friendly weather conditions. A watch is issued when a tornado is likely to occur, while a warning indicates a more immediate threat.

The NOAA offers tornado predictions starting a week in advance, although the risk, labeled as a slight, moderate or high risk, can change over the week. Watches and warnings are usually issued with only a few hours notice. Local National Weather Service offices issue predictions for tornadoes and other severe weather in their immediate areas.
