Friday's heat comes after storms rolled through central North Carolina Thursday evening. A fire inside the attic of a Durham home on Thursday was blamed on a lightning strike, officials said.

"We're going to have to wait for a cold front to come in Saturday night to clear all this out," WRAL Chief Meteorologist Greg Fishel said.
