A warm front generally has a gradual slope. It produces heavy precipitation not only over a large area, but small areas as well.

The weather associated with a stationary front is similar to that produced by a warm front. And a warm front generally brings drizzly precipitation. :)
cold front
The precipitation generally occurs before the front moves in.
stationary front
An active front is a boundary between two different air masses, which produces cloudiness and precipitation.

The type of front which will lead to turbulent air and precipitation is a cold front. When warm cold air collides with warm air, it will generally produce severe weather.
The weather associated with a stationary front is similar to that produced by a warm front. And a warm front generally brings drizzly precipitation. :)
The Warm Fronts are the one that usually produce several hours of moderate-to-light precipitation over a large region.
Not normally before a warm front, precipitation comes before and after a cold front. When you have warm air and a cold front comes through, you mix warm with cold and that brings precipitation.
Precipitation usually comes before or during the passage of a cold front.
