    As asked earlier - how common is it for the polar vortex to split in midwinter? Is this a once in a lifetime event (now perhaps happening more frequently)? Unprecedented in its combined details ("perfect storm")? Or just an unusually weird winter, but happens every few decades? Getting more frequent?

    Because otherwise, it's just weather porn.
