Wind chill advisories and warnings are in effect for 32 states from Montana to southern Florida on Tuesday.

Washington, D.C. is expected to see its coldest morning in 18 years and if the nation's capital gets to 5 degrees on Tuesday, it will tie a daily record low that was set 130 years ago.  The wind chill in D.C. is expected to be eight below zero.  

Detroit, meanwhile, is forecasting a high temperature of 1 degree below zero and a wind chill of minus 37 degrees.

The unrelenting cold will push wind chills in northern Florida to as low as 9 degrees and minus 6 degrees in Atlanta.  In New York City just before dawn Tuesday, temperatures were in the single digits and the wind howled, sending commuters scurrying down wind-swept streets.

Relief is on the way as wind chill warnings are to expire Tuesday in the Midwest as the polar air begins to retreat north and temperatures will make a gradual upward climb through the end of the week.

Schools in Minneapolis and Chicago will remained closed for a second straight day.  School districts across the South, including those in Atlanta, Alabama, the Carolinas and north Florida will also be closed on Tuesday.
