Missouri to Maine, and nearly 5,000 flights have been cancelled on Sunday around the country. The winter storm has also caused icy roads in Northeast US and wind chills below zero.
After a major winter storm hit a wide portion of the country, bitter cold is also settling in and is expected to get much colder overnight. According to the National Weather Service temperatures of minus 40F (minus 40C) are expected in the New York City area while in New England temperatures will fall to as low as minus 20F (minus 29C) around Boston and as low as minus 35F (minus 37C) in parts of Vermont, Maine and New Hampshire.
Also, temperatures across the Great Lakes, Ohio Valley and the Mid-Atlantic will drop 10 to 20 degrees Fahrenheit below average. Philadelphia has also been hit with cold temperatures, icy roads, and below-zero wind chills Monday morning.
It seems the storm was caused by the clash of an Arctic high-pressure system with a low-pressure system coming through the Ohio Valley. Air travel, canceled trains, traffic jams, and power outages have been happening all weekend and seem to still continue.
