The eastern United States is in for another day of steamy weather Thursday and the sweltering heat isn't expected to break until a cold front forces temperatures down into the 80s this evening, said the National Weather service. Heat warnings were posted from Massachusetts to South Carolina and in parts of Oklahoma. Since Sunday, authorities have confirmed heat played a role in at least 13 deaths and may be related to seven more. A heat wave was blamed for as many as 164 deaths last week in California, CNN reported.
