A slow-moving storm with bands of heavy rain drenched the Triangle on Thursday afternoon, and promised more for the evening.

Showers and thunderstorms may last through 11 p.m., said Nick Petro, a meteorologist with the National Weather Service in Raleigh. Then the storm is expected to move east and there is little chance of storms overnight.

Severe thunderstorm and flash flood warnings were posted for much of the Triangle, but most were canceled by the National Weather Service by early evening.

On Friday, there is a 15 to 20 percent chance of rain throughout the Triangle. A cold front that is moving through over the weekend is expected to bring showers and storms late in the day Saturday. By Sunday, the storm is expected to have cleared, making way for a nice day to finish the weekend, said Petro.
