How do warm fronts cold fronts affect the weather?

Answer 1

Warm fronts give rain and clouds, cold fronts cause skies to clear , together they cause tornado's and big storms. When a warm front moves in, the cold air is pushed up. There are clouds and possibly rain, then the opposite happens when a cold front moves in. Cold fronts move under and overtake the warm mass and go underneath. This causes the skies to clear because of the rapid change in air temperature.

ANOTHER ANSWER.

So basically, a warm front can bring hours or days of wet weather and steady rain. A cold front can bring thunderstorms and even tornadoes. A stationary front can bring light wind and precipitation.

Answer 2

Warm fronts typically bring warmer air, leading to rising temperatures, and are associated with long periods of steady precipitation. Cold fronts, on the other hand, bring colder air, leading to falling temperatures, and are associated with more intense but shorter periods of precipitation, often thunderstorms. Both warm and cold fronts can also bring changes in wind direction and atmospheric pressure.
