| Cold Front | A weather front that forms when a cold air mass meets and pushes under a warm air mass. Violent storms are associated with this type of front and fair, cool weather usually follows. |
| Warm Front | A type of weather front that forms when a mass of warm air overtakes a cold air mass and moves over it. Rain and showers usually accompany this type of front and hot, humid weather usually follows. |
| Stationary Front | A weather front that forms when a warm air mass meets a cold air mass and no movement occurs. This type of front can cause weather conditions that can last for days. |
