Millions brace for weekend of severe storms on the East Coast

More than 90 million Americans are under a Level 2 (and higher) severe weather threat this weekend as a slow-moving cold front sweeps from the Ohio Valley into the Northeast, bringing widespread thunderstorms, damaging winds, heavy rain and the possibility of tornadoes. Flash-flood threats are in place for parts of the Ohio Valley Friday and for New York City and neighboring areas Saturday, with the Northeast likely to bear the brunt on the weekend. The pattern comes amid a heat dome and wildfire smoke that could affect temperatures, but forecasters expect the front to bring relief by Sunday.
