May starts with unseasonable spring chill across Northeast, Mid-Atlantic

Those anticipating a summer preview across the Northeast and the Mid-Atlantic will have to wait a few more weeks, with temperatures expected to remain 10 to 15 degrees below average as the calendar turns to May. Nearly 230 million Americans will experience below-average temperatures on  Saturday. Parts of the Interstate 95 corridor like New York City and Washington, D.C., will only reach the upper 50s and low 60s on Saturday, with overnight lows in the low 40s.
