This is called a tornado watch.
"Tornado Alley" is the term commonly used to reference the area in the United States where tornadoes are most frequent. It includes parts of Texas, Oklahoma, Kansas, and Nebraska.
It is possible, but long term predictions for tornadoes are not possible. If a place is going to be hit, we will know a few minutes in advance.
from one extreme to another
Tornadoes are sometimes called twisters, but tornado is the preferred scientific term.
A tornado threat is not a formal term in meteorology. It merely refers to the potential danger an area might face from tornadoes and the magnitude of that danger.
In the long term tornadoes are predicted by looking at factors such as temperature and wind speed and direction at different levels of the atmosphere and by monitoring any storm systems that might come through the area. In the short term tornadoes are predicted by scanning thunderstorms with doppler radar and looking for signs of strong rotation.Scientists study tornadoes primarily with doppler radar as well, which can pick up information on the winds inside the funnel it you can get close enough. A few have deployed probes inside of tornadoes to take measurements.
Tornadoes can be called twisters, but tornado is the preferred term. Hurricanes are also called tropical cyclones, though that is a somewhat broader term.
Tornadoes can be predicted to a limited degree. In long-term forecasts over the course of hours and days meteorologists analyze weather patterns and run forecast models. This type of analysis can show when, to within a few hours, a region might experience tornadoes. Such forecasts cannot tell where or when individual tornadoes will occur, only the general risk for a large area. Short-term forecasts make use of Doppler radar, which can detect rotation in a storm, and eyewitness reports. This sort of short-term reporting can tell which storms are capable of producing tornadoes.
They are also called fire whirls. This is the term preferred by scientists as they technically are not tornadoes.
Circuit Buddha is a touristic term signifying the Tour Pilgrimage of important Buddhist places in India.
The term you are looking for is tornado watch.
That is impossible to predict. Tornadoes cannot be predicted in the long term. Lead times in forecasting tornadoes are measured in minutes, not months.
