Description: Fox Weather Now explains the phenomenon of a polar vortex collapse. Initially a strong, circular flow containing cold air, the vortex can weaken and become wavy, allowing lobes of Arctic air to move south. However, this particular collapse is expected to displace cold air away from the Lower 48, leading to a mild temperature pattern through mid-March.
