Severe storms will threaten the Northeast this weekend before the grueling heat takes a break.
Highs will soar well into the 90s and even 100s on Saturday, challenging records for many of the big cities of the Northeast. Philadelphia and Washington, D.C., are among the cities expected to crack the 100-degree mark.
"Saturday could potentially be the hottest day of the summer for Philadelphia, Washington, D.C., and other cities of the Northeast," AccuWeather.com Expert Senior Meteorologist Alex Sosnowski said.
The thunderstorms will fire along the northern edge of the most brutal heat, while cooler air begins to filter into the portions of the Midwest and New England.
The battlegrounds for severe storms on Saturday afternoon will span from southeastern New England to the eastern Great Lakes. Boston, New York City, Syracuse, Buffalo and Cleveland will be at risk during the afternoon and evening.
The biggest threats will be damaging wind gusts higher than 60 mph. The strongest storms will also be capable of producing large hail.

The storms will spread farther south overnight with Philadelphia, Atlantic City, Wilmington and Pittsburgh possibly lying in the path.
Thunderstorms will rattle even farther south on Sunday. Baltimore and Washington, D.C., may be in the path of damaging thunderstorms.
The same system that spawned deadly tornadoes in Oklahoma will reach the Northeast on Thursday.
With one day remaining before Memorial Day weekend, the Sandy-battered Jersey coastline is hustling to finish last-minute preparations.
The Memorial Day weekend will begin cool, windy and rainy in New England and part of the mid-Atlantic.
Thunderstorms will slow cleanup efforts in Moore, Okla., into the upcoming Memorial Day weekend.
