Nothing is certain, but a major sign is rotation in the clouds during a thunderstorm with a lowering of the cloud base. The stronger the rotation, the more likely there will be a tornado. When a storm is approaching the most important thing to do is listen to your local radio or television station, or to whatever device carries current, local weather reports. Meteorologists are able to tell when a storm is likely to become violent, and whether it is the type of storm that can spawn a tornado. Without the technology used by the weather service, it is not possible to tell with any certainty whether a tornado is possible in any particular storm.
