What weather does a dry line often trigger?

• A. Quiet weather
• B. Thunderstorms and severe weather
• C. Snowstorms
• D. Drought

Answer: (B)

The dry line is a boundary where very warm, dry air from the Southwest meets hot, humid air from the Gulf. This sharp contrast in moisture and temperature creates instability in the atmosphere. When the moist air is lifted along or near the dry line, it can rise vigorously and form strong thunderstorms. If there’s enough moisture and wind shear, those storms can become severe, producing damaging winds, large hail, or even tornadoes. Because the dry line supplies the fuel and lifting for convection, thunderstorms and severe weather are the typical outcomes, not snowstorms, drought, or quiet weather.
