The National Weather Service warned that high temperatures well into the 80s will begin to challenge daily records.

The heat was driven by a strong ridge of high pressure, often called the Bermuda High.

The heat wave followed the hottest March on record for the continental U.S.

The National Weather Service cautioned that heat is the No. 1 weather-related killer in the U.S.

Record-Breaking Temperatures

The heat wave shattered daily temperature records across multiple states.

Philadelphia was forecast to reach 91°F on Wednesday, breaking a record set in 1941.
