Cold fronts produce most of the severe weather most of the time. This is because the cold air undertakes the warm moist air ahead of the front.
A wide variety of weather can be found along an occluded front, with thunderstorms possible, but usually their passage is associated with a drying of the air mass. Within the occlusion of the front, a circulation of air brings warm air upward and sends drafts of cold air downward, or vice versa depending on the occlusion the front is experiencing.
