6. when cold air, often originating from Canada, moves across the open waters of the Great Lakes.
8. indicates a storm is possible but not guaranteed.
12. a whirling column of air and water mist.
14. a radar tracking system using the Doppler effect to determine the location and velocity of a storm, clouds, precipitation, etc.
15. least common type of thunderstorm, but they have a high propensity to produce severe weather
16. a rotating funnel-shaped cloud forming the core of a tornado or waterspout.
17. powerful winds that descend from a thunderstorm and spread out quickly once they hit the ground
19. a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.

1. a mathematical model constructed around the full set of primitive, dynamical equations which govern atmospheric motions
2. a group of storms arranged in a line, often accompanied by “squalls” of high wind and heavy rain.
3. a map displaying the likely weather forecast for a future time.
4. a storm-scale or mesoscale boundary separating thunderstorm-cooled air from the surrounding air
7. detects precipitation and atmospheric movement or wind.
9. a scale of tornado severity with numbers from 0 to 6, based on the degree of observed damage.
10. appear to be "rolling" about a horizontal axis
11. a localized column of sinking air
12. much smaller and more compact than a shelf cloud and is usually under a rain free cloud base.
13. often associated with squall lines, and many times they are reported as wall clouds, funnel clouds, or rotation
18. take cover immediately.
