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. Even in a summer already filled with stretches of very hot weather, this week will be stubbornly brutal, with no relief in sight until the weekend brings thunderstorms to the region, they 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)
