How do winter storms form? Winter storms get their energy from the clash of two air masses of different temperatures and moisture levels. They usually form when an air mass of cold, dry, Canadian air moves south and interacts with a warm, moist air mass moving north from the Gulf of Mexico. The area where these two air masses meet is called a front. If cold air advances and pushes away the warm air, it forms a cold front. When the warm air advances and it rides up over the denser, cold air mass - it forms a warm front. If neither air mass advances, it forms a stationary front.
