Rollerbladers skate past fishermen sitting in the shade as they seek relief from high temperatures by Lake Calhoun in Minneapolis, July 18, 2011. A heat wave with oppressive temperatures and stifling humidity lingered and intensified in the midsection of the country on Monday and was expected to expand eastward as the week continued.
