The cold weather 'bomb' headed for the East Coast may be the 'worst you've ever seen,' according to a meteorologist

• The Northeast will experience some of the coldest temperatures in decades on Friday and Saturday as a 'cold weather bomb' bears down on the region.
• Temperatures are expected to plummet to below zero Fahrenheit in New York City on Friday night.
• Snowfall may actually insulate infrastructure from freezing too much.

A 'cold weather bomb' is bearing down on the East Coast. At least one meteorologist is warning that the frigid temperatures following the storm could be "literally the worst you've ever seen," with low temperatures not seen in decades.

Gary Szatkowski, a meteorologist who spent 35 years with the National Weather Service, tweeted on Wednesday morning that the snowfall associated with the storm isn't the biggest issue.

Szatkowski explained on Twitter that a few inches of snow can serve as infrastructure insulation, protecting water pipes and subway tracks from freezing in the extreme cold.
