Arctic Blast Brings Season's Coldest Temperatures and Snow to Eastern U.S.

A powerful surge of Arctic air is descending across the central and eastern United States. This system is delivering the coldest temperatures so far this season to the Midwest and Northeast. The same weather pattern is also bringing the first significant snowfall to the Mid-Atlantic region. Millions of residents are experiencing subzero wind chills and hazardous travel conditions. Meteorologists classify this event as an "Arctic blast," a period of intense cold air moving south from the Arctic Circle. Authorities advise people to limit time outdoors and to check on vulnerable neighbors during the extreme cold. The National Weather Service has issued wind chill advisories and winter weather warnings across more than a dozen states. They expect the dangerously cold conditions to persist for several days.
