LSU'S Mike VII experiences his first snowfall during a snow day on Friday, December 8, 2017, in Baton Rouge, La.

It was really cold Tuesday morning in southeast Louisiana.

In New Orleans, temperatures dropped to 25 degrees shortly before 7 a.m. at the Louis Armstrong International Airport, tying the record low previously set for Jan. 2 in 1984.

Baton Rouge didn’t break any records, but came close. At 7 a.m., the Baton Rouge Metro Airport recorded a temperature of 21 degrees, just 1 degree warmer than the record low of 20 degrees set in 1979.

The arctic blast that has swept across the eastern United States from north to Deep South is expect to remain in the region for a few more days. 

A "nor'easter-type system" off the eastern seaboard is helping to slow a warming trend, keeping a mass of cold air over a wide swath of the eastern U.S., said Gavin Phillips, a forecaster with the National Weather System.

Lows are forecast to be in the teens Tuesday night and the 20s Wednesday, Thursday and Friday nights in the Baton Rouge area. In the New Orleans area, lows will be in the 20s Wednesday and Thursday nights and in the 30s on Friday night.
