Which condition would most likely require the National Weather Service to issue a severe thunderstorm warning? (1 point)

Question

• a front moving out of an area
• a meeting of two air masses with major differences in temperature and moisture
• an air mass developing over a large body of water
• a large amount of moisture in the air condensing to form clouds

Answer 1

The condition that would most likely require the National Weather Service to issue a severe thunderstorm warning is:

• a meeting of two air masses with major differences in temperature and moisture.

This is because the collision of differing air masses can lead to strong lifting and instability in the atmosphere, which are key ingredients for the development of severe thunderstorms.
