A vigorous disturbance has the potential to bring severe thunderstorms across the mid-Atlantic on Friday, including major cities such as Washington, D.C., Philadelphia, New York and Albany.
Heat and humidity will build across the region into the end of the week to help fuel the stormy weather.
The disturbance will clash with near 90-degree heat and humidity liken to the tropics.
According to Northeast Weather Expert Dave Dombek, "Heavy thunderstorms are likely to rattle areas from North Carolina to Vermont, New Hampshire and part of Maine Friday into Friday night."
Torrential downpours and damaging winds are possible with the storms. Strong winds can lead to downed trees and power outages across the region, while torrential downpours can produce flash and urban flooding.
"Commuters in the East should expect delays Friday into the first part of the weekend," Dombek added.
Low-lying stretches of streets and highways can quickly take on water, while there is the potential for a few small streams to rise out of their banks.
As locally severe thunderstorms approach airports, flight delays are possible.
By Saturday, showers and thunderstorms will shift to much of New England and the southern Atlantic Seaboard. There is the potential for severe thunderstorms in Boston and from Norfolk, Va. to Savannah, Ga.
The disturbance will bring the potential for waterspouts over the lower Great Lakes late in the week and the weekend.
In addition, a significant portion of the Midwest will be targeted by torrential rainfall and locally severe thunderstorms.
