'Heavy' Storms Poised To Break Good Weekend Weather Streak: NWS

Rain free weekends, which were plentiful this summer, are coming to an end.

Up until now, the region had 16 straight weekend days without measurable rain, according to the Philadelphia Inquirer. But all that comes to an end soon, likely Saturday.

The National Weather Service has issued a Hazardous Weather Outlook starting Saturday, saying showers and thunderstorms may produce “heavy rain.”

“Flooding in urban, poor drainage and low lying areas and Saturday and Saturday night” is possible, the Hazardous Weather Outlook says.
