Causes of Snowfall in St. Paul

Snowfall in St. Paul, Minnesota, is primarily caused by the city’s location within the mid-latitude zone, where cold air from the north and warm, moist air from the Gulf of Mexico collide. This collision creates an unstable air mass that rapidly rises, leading to the formation of clouds. As the moisture in these clouds freezes, it crystallizes into snowflakes. The size and shape of these snowflakes are determined by temperature and humidity conditions. Wind currents then carry the snowflakes to the ground, resulting in snowfall.
