Hazardous Weather Outlook In PA Ahead Of Mother's Day Weekend

We've had a nice stretch of sunshine this week, but it's about to end. The National Weather Service has issued a Hazardous Weather Outlook, saying severe thunderstorms are possible later on Thursday, and could bring damaging winds and large hail.

The greatest risk for severe thunderstorms Thursday in the Philadelphia region is between 4 and 8 p.m.

The bad weather news doesn't end there, unfortunately. It looks to be a less than ideal forecast for Mother's Day weekend, with "multiple rounds" of showers and storms predicted throughout Saturday and Sunday, and into early next week.

"There is at least some potential for locally heavy rainfall and flooding during this period. However,
considerable uncertainty remains," the National Weather Service said in its Hazardous Weather Outlook.

Saturday will be rainy with a chance of showers and thunderstorms throughout the day. The chance of precipitation is 60 percent.

On Sunday, Mother's Day, the forecast calls for showers in the morning and cloudiness throughout the day. More showers are possible Sunday night.
