Why does a warm front usually bring a light and steady rain?

• warm fronts bring extremely low pressure
• weather that is not intense always happens at any kind of front
• a warm air mass violently crashes against a cold air mass, so the weather is wet
• a warm air mass slowly climbs up over the cold air mass, so the weather is less intense
