Answer to Question 1
Tornadoes are most often spawned along the cold front of a midlatitude cyclone or in association with a supercell thunderstorm. Air masses associated with midlatitude cyclones are most likely to have greatly contrasting conditions: continental polar air may still be very cold and dry, whereas maritime tropical air is warm, humid, and unstable. The greater the contrast when these air masses meet, the more intense the storm.
Answer to Question 2
Tornado watches alert the public to the possibility of tornadoes over a specified area for a particular time interval. Watches serve to fine-tune forecast areas already identified in severe weather outlooks. A tornado warning is issued when a tornado has actually been sighted in an area or is indicated by weather radar. It warns of a high probability of imminent danger.
