Portions of the mid-Atlantic remained under winter storm warnings on Tuesday morning, a day after snow fell along the East Coast and tornadoes were reported in four southern states.

The National Weather Service issued the warnings in parts of New York, Pennsylvania, Ohio, West Virginia, Maryland, Virginia and North Carolina, saying those regions should expect more winter weather this morning. Winter weather advisories were also issued across New England.

The winter weather is expected to transition into rain later today as temperatures rise. Residents of all of the affected states should monitor their local forecasts.

The storm came after several mid-Atlantic and New England communities recorded record low temperatures on Sunday, as bitter cold helped shatter the previous records for Valentine’s Day.

Notably, the National Weather Service said temperatures dipped to -1 degree Fahrenheit in New York’s Central Park, the coldest temperatures recorded on Feb. 14 in the park in 100 years.

In upstate New York, the service said temperatures reached 37 degrees below zero in Watertown and 23 degrees below zero in Syracuse. Those broke Feb. 14 records that had stood since 1979.

Monday’s winter storm brought snow and freezing rain to several states, and the National Weather Service reported a storm-high total of 15 inches fell near Rupert, West Virginia.

Parts of Virginia and Maryland received nine inches of snow, while cities in Kentucky and Tennessee saw more than six inches. Lighter totals were recorded in a broad area from Maine to Georgia, with some areas receiving some freezing rain.

The National Weather Service’s Storm Prediction Center also received 17 reports of tornadoes and high winds in Louisiana, Mississippi, Alabama and Florida on Monday.

The reports mentioned downed trees and power lines, damaged homes and buildings. The extreme weather caused at least one injury in Alabama, where Covington County officials reported a tornado destroyed a mobile home.

Tornadoes damaged nine homes, a school and a chicken house in Copiah County, Mississippi. The service also said a tree fell on a semi truck, briefly entrapping one person.

In Smith County, Mississippi, tornadoes caused “major damage to homes and structures” near Sylvarena, and blew a gas pump away from a grocery store.

Damage from heavy winds and hail was reported in several other southern communities.

The extreme weather, particularly the winter storm, had a significant impact on travel.

Flight monitoring website FlightAware.com reported 1,623 United States flight cancellations on Monday, including about 300 apiece at Washington’s Reagan National Airport and New York’s Laguardia Airport. More than 575 flights were cancelled on Tuesday morning, the site reported.
