 Meanwhile, the eastern seaboard is bracing for rain and storms Saturday. Meteorologist Jen Carfagno from our partners at the Weather Channel has the forecast. Hi, Jen. Good day to you, Lindsay. The heat is expanding. We've had this big heat wave and heat dome across the west. Now we see it extending into the middle of the country and really through the southeast and eventually northeast Sunday and into next week. 209 million going above average with that heat here is going to be extensive with the heat and the humidity.
