The Arctic blast that descended this week on a swath of the country stretching from the Rocky Mountains to New England continued Tuesday, bringing record-breaking low temperatures, snowfall in some Northeast areas and school closings in the Mid-South.
Record cold continued to spread from the Plains toward the East Coast, the National Weather Service Prediction Center said on Tuesday morning. Early-season snows across western to northern New York and northern New England will taper off Tuesday, it said.
The air mass, which led to more than a thousand flight cancellations, is expected to break more than 150 daily-temperature records across the eastern half of the country through Wednesday.
It was expected to reach minus 1 degree in Sioux City, Iowa, and 25 degrees in Greenwood, Miss., on Tuesday. On Wednesday, temperatures in Austin, Tex., Houston and New Orleans are expected to dip to the 20s.
Areas around Pittsburgh received light snow overnight Monday and into Tuesday morning, the Weather Service said on Twitter. Additional snow accumulation is expected through the day.
The National Weather Service in Indianapolis said on Twitter that Tuesday morning’s frigid temperature at 8 degrees set the record for the coldest temperature this early in the season.
Low temperatures on Tuesday morning in Tennessee and Arkansas also prompted school closings and delayed openings in several counties, according to local reports. The wind chills in the Memphis area on Tuesday are expected to be 10 degrees.
Temperatures plunged to record-breaking lows or tied with existing records in several areas in the Great Plains on Monday, according to Brian Hurley, a meteorologist with the National Weather Service. Northern Montana reached minus 19, beating the previous daily temperature record by three degrees, he said.
The cold front is expected to stretch from the Southern Plains to the Ohio River Valley on Tuesday, and by Wednesday, it will shift to the Gulf and East Coasts, said Alex Lamers, another meteorologist with the Weather Service.
Snowfall could measure up to a foot in the Northeast, with the greatest amounts in the Adirondacks, the Green Mountains of Vermont and northern Maine, according to the Weather Service. Many schools, including in the Detroit and St. Louis areas, closed early on Monday and canceled classes on Tuesday, according to local television stations.
The weather also affected road conditions.
In Kansas, an 8-year-old girl was killed Monday after a truck lost control on the icy highway, crossed the centerline and hit her vehicle head on, causing another car to rear-end it, according to the Kansas Highway Patrol’s online crash log.
Three people in Michigan were killed in a two-vehicle crash caused by poor road conditions, the Eaton County Sheriff’s Office said in a statement.
A plane slid off an icy runway after landing at O’Hare International Airport in Chicago on Monday morning. None of the 38 passengers or three crew members were injured, according to an American Airlines spokeswoman.
More than a thousand flights were canceled at Chicago’s airports on Monday, according to the city’s Department of Aviation.
The air mass formed over the Arctic Ocean late last week, dipped south through Canada over the weekend, and spread southeast across the United States, Mr. Lamers said.
The Arctic front arrived around Monday, which was Veterans Day, prompting some event organizers to make new plans.
The low temperatures on Monday night were particularly concerning in Wyoming, where officials were still searching for a 16-year-old autistic boy who went missing the day before, wearing only his pajamas and a hooded sweatshirt. Law enforcement have been using canine teams, helicopters and certified human trackers, according to the Natrona County Sheriff’s Office.
Mr. Lamers said temperatures should start to rise after Wednesday.
“It’s not uncommon to get the first significant surge of Arctic air in November, but it is unusual how far south it’s getting — with potential freezes in the Gulf of Mexico,” he said.
