The end of the heat wave that has gripped the Ohio Valley and Northeast this week is near, but it will come at a price to some in the form of powerful thunderstorms on Saturday.
A cold front will set off clusters of heavy, gusty thunderstorms in the sultry air on Saturday afternoon and these storms will march east through the evening. The most intense thunderstorms will produce damaging wind gusts, hail and torrential downpours. A couple of tornadoes are also possible, but the threat is low.
The storms could cause localized downed trees and power outages, as well as flash and urban flooding. Travel delays on roads and at the airports are likely as storms develop and roll through.
Locations that are in the threat area include Cincinnati, Pittsburgh, Albany, N.Y. and Augusta, Maine, during the afternoon, reaching Boston, Hartford, Conn., New York City, Trenton N.J., Philadelphia and Washington, D.C. late in the day.
Thunderstorms will be a threat to outdoor evening concert events at Lincoln Financial Field in Philadelphia (Taylor Swift), SummerSounds Concert near Washington, D.C. and Yankee Stadium (Jay-Z and Justin Timberlake).
In the wake of the thunderstorms and passage of the cold front it will be cooler and not as humid across the Ohio Valley and Northeast on Sunday.
