Let’s look at the weather that occurs as a result of the cold front in South Africa. There are two different weather conditions that occur before and after the cold front has passed.
Weather in front of the cold front
- Cool temperatures
- Very low pressure
- Overcast conditions, cumulonimbus clouds
- Thunderstorms
Weather behind the cold front
- Cold temperatures
- High pressure
- Partly cloudy conditions, cumulus clouds
- Light rain
Note that as a mid-latitude cyclone moves from west to east, we experience the warm air mass in front of the cold front first, then the air behind the cold front.
