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.

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 over the next two days.

It is expected to reach minus 1 in Sioux City, Iowa, and 25 degrees in Greenwood, Miss., on Tuesday. On Wednesday, temperatures in Austin, Houston and New Orleans are expected to dip to the 20s, the Weather Service said on Twitter. Additional snow accumulation is expected through the day.
