    Forecasters warned Friday that the Northeast would experience what could be the coldest temperatures in over a decade this Valentine's Day weekend, NBC News reported. 

    Several cities are facing the prospect of subzero temperatures, the product of a weather system called the polar vortex, a large cyclone that sits above the North Pole all year round. The National Weather Service said the "life threatening" icy blast was set to arrive in the region Saturday, but the coldest air would not arrive until Sunday morning.

    Boston's forecast low of -2 looked relatively balmy compared to the outlook for -9 in Hartford, Connecticut. Albany was forecast to experience -10 with -11 possible in Worcester, Massachusetts, according to The Weather Channel.

    Meanwhile, New York City is forecast to have 2 degrees on Saturday.

    "For people stepping outside on Sunday morning, it's going to be like walking into a freezer," said Weather Channel Lead Forecaster Michael Palmer.
