Continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. As they move into warmer air, they can trigger precipitation.
When cold air runs into warm air on a large scale it forms a cold front. If the warm air mass is unstable enough this can trigger thunderstorms, potentially strong ones. Given a few other conditions these storms can begin to rotate and produce tornadoes. Most strong thunderstorms are associated with cold fronts. However, another significant source of tornadoes. This is a similar scenario to a cold front, only there is a dry air mass pushing into a moist one with little temperature difference. A dry line is even more effective at producing tornadoes than a cold front.
The Continental Polar is composed of cold dry air.

The boundaries between air masses are called front. The types of air mass and movements involved determine the type of front. Warm front: a warm air mass plows into a cold air mass. Cold front: a cold air mass plows into a warm air mass. Stationary front: The warm and cold air masses move little relative to one another. Occluded front: A cold front catches up with a warm front, sending the warm air mass aloft. Dry line: a dry air mass plows into a moist air mass.
