After a cold front sent temperatures plummeting last week, warm weather is now moving in across a large swath of the country, bringing potentially record-setting temperatures to more than 215 million people.
In cities across the Southwest, temperatures will top out in the 70s, which is a few degrees above normal for this time of year. As you move east toward Texas to the Tennessee Valley, the temperatures will rise into the 80s.
The Central Plains will also see temperatures soar into the 70s, roughly 20 degrees above average.
Multiple cities, including Nashville and Chattanooga, Tennessee; Huntsville, Alabama; and Junction, Colorado, could all set new record highs on Tuesday, which is forecasted to be the warmest day of the week for most of the country.
The warm weather will be short-lived for some people in the Northeast. By the end of the week, a cold front is forecast to move in, dropping temperatures by 10-15 degrees.
