Squall lines with an almost unbroken line of threatening dark clouds and sharp changes in wind direction, generally precede which front?

🔍 Key Concepts

• Relationship between front speed and severity of weather along the boundary • Typical weather associated with a cold front vs a warm front • How squall lines and abrupt wind shifts relate to strong lifting of warm, moist air

💭 Think About

• Think about which type of front usually brings the most violent, short‑lived thunderstorms and the most sudden changes in wind and pressure. • Consider whether slow or fast moving fronts are more likely to create a narrow band of intense, organized squalls just ahead of the front line. • Ask yourself which front normally has a steep temperature gradient and forces warm air to rise quickly along a sharp boundary.

✅ Before You Answer

• Verify which front is most commonly associated with narrow, nearly continuous lines of thunderstorms (squall lines) just ahead of it. • Check which front type usually causes sharp wind shifts and rapid pressure and temperature changes over a short distance. • Confirm that the front you choose is typically fast moving with a steep frontal slope, not broad and gentle.
