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.
Cold Front - Cold air is overtaking warm air. Since cold air is denser than warm air, cold air undercuts a warm air mass. This produces a more concentrated line of heavy precipitation as the push of the cold air literally lifts the warm air just ahead of the front. This lifting of the air many times causes thunderstorms or very heavy showers.
