prize1-5, Exercise 2: The passage of a depression

Model answer:

Ahead of the warm front the pressure falls and high wispy cloud thickens and lowers, followed by steady rain. After the warm front passes, you are in the warm sector: mild, damp and cloudy, with pressure steady or falling slowly. The cold front brings a narrow belt of heavy rain or showers, possibly thunder, and the wind veers. Behind it, pressure rises, the sky clears and it turns colder and brighter.
