Weekend Forecast: Severe Weather Possible In PA, Forecasters Warn

Severe weather could hit Pennsylvania this weekend, with strong, possibly damaging thunderstorms on Sunday, forecasters say.

The weekend is expected to start with nice weather, but the worst is expected for the second half of it.

Strong storms that have impacted the Midwest are expected to move into the area and cause strong, "possibly damaging" thunderstorms with heavy rain hitting the hardest on Sunday afternoon, according to AccuWeather.

Some thunderstorms will be severe, coming with hail and damaging winds, the Weather Channel warns.

Downpours will expand northeastward over the rest of the mid-Atlantic during Saturday night and continue on Sunday, according to AccuWeather.

Enough rain could fall to cause water to collect in poor drainage areas and on some city streets, according to AccuWeather.

"There is the potential for strong to locally severe thunderstorms on Sunday," AccuWeather Chief Meteorologist Elliot Abrams said in a release. "The system coming in later this weekend will be strengthening, and it is the right time of year to expect nasty storms in such a situation."

As the downpours cross major highways and storms approach major airports, significant travel delays can occur, according to AccuWeather.

The good news is the early part of next week looks clear and calm.
