The northeastern United States sweltered this week in a scorching summer heat wave, complete with stagnant, sticky air and no winds for relief, forecasters said.

"Plain and simple, this week may feel the worst of any week for this summer in the Northeast," said Accuweather.com meteorologist Alex Sosnowski. (Reuters)
