Cold fronts are most often associated with the severe storms that produce hail and tornadoes.
Tornadoes, hail and other forms of severe weather most often form ahead of cold fronts.
Hail and tornadoes would most likely be associated with a cold front or dry line.
Hail and tornadoes are most often associated with cold fronts, but can occur with dry lines or, lest often, warm fronts.
Cold fronts most often bring tornadoes, hail, and other forms of severe weather.
A cold front would likely be a front that would produce hail and tornadoes in an area because cold fronts are different than warm fronts. Cold fronts are usually fronts that cause storms and if they have the right recipe it could produce damaging winds, hail and sometimes if it's very strong, tornadoes.
Tornadoes are least likely to form in association with a warm front, though it can happen.
Tornadoes are most likely to be associated with a cold front.
Cold fronts are most likely to produce thunderstorms and tornadoes.
Tornadoes are more likely to form along a cold front, but they can occasionally form along a warm front. Many tornadoes form in an area called Larko's triangle, between a warm front and cold front. Some tornadoes form along a dry line, and in fact a try line can be more proficient at producing tornadoes than a cold front. Still other tornadoes form from tropical systems, which do not involve any sort of front.
Tornadoes can occur along a warm front, but you are more likely to find them along a cold front or dry line. Tornadoes can also occur in the absence of any sort of front. Warm fronts often produce precipitation but don't usually result in severe weather.
