Not since 2014’s so-called polar vortex has the state seen such sustained frigid temperatures. According to meteorologists, the culprit this time is a blast of arctic air hitting the East Coast.
“This appears to be the coldest air mass for the last four or five years,” said National Weather spokesman Bill Simpson. “It’ll probably be an extended period of cold air, probably breaking by next week. So we’re looking at well, well below our normal temperatures.”
