"The dangerous combination of high temperatures, plus high humidity, will make it feel like 100-105+° during the afternoon and early evening hours," WGAL Chief Meteorologist Christine Ferreira said.

An "extremely dangerous heat wave" is continuing to scorch a huge area of the eastern United States June 23, affecting tens of millions of people.

The official heat wave will begin today, following yesterday's fall just below the 90-degree mark, thanks to the spotty storms. Expect Monday to approach 100 degrees in many areas across the Delaware Valley,
