PHILADELPHIA – A dangerous heat dome is building over the eastern United States, threatening to bring record-shattering, triple-digit temperatures to the Northeast just in time for the Fourth of July holiday week.
As a surge of humid air moves in, feel-like temperatures will soar past 100 degrees, creating hazardous conditions that will linger across the region for several days. Residents across the I-95 corridor are being urged to prepare for what will likely be the most intense and widespread heat wave of the summer so far.
