Hazardous Weather Outlook Issued As Weekend Storms Approach

Looks like the summer fun might be put on hold a bit this weekend.

More severe thunderstorms with hail and strong winds are possible Saturday in Pennsylvania, mainly in the Eastern and Central parts of the state.

The National Weather Service has issued a "Hazardous Weather Outlook" in 10 counties, saying the severe thunderstorms will possibly hit Saturday afternoon in the evening and could come with damaging wind gusts and hail.

Counties included in the Hazardous Weather Outlook include: Bucks, Chester, Delaware, Montgomery, Philadelphia, Carbon, Monroe, Berks, Lehigh and Northampton.

"Those with outdoor plans or events should be aware of the risk," the Hazardous Weather Outlook says.

Locally "violent" thunderstorms could come with winds capable of downing trees and power lines, according to an AccuWeather release. The probability of tornadoes appears to be low, although isolated tornadoes can occur in these situations, according to The Weather Channel.

Those with plans to swim at a local pool or attend an outdoor festival should keep an eye to the sky and be prepared to seek shelter at the first clap of thunder, AccuWeather recommends. 

Severe thunderstorms will become more possible from the Upper Midwest into the Northeast as building heat and humidity interact with an active jet stream, according to The Weather Channel.

A hail storm rocked the Philadelphia region Wednesday, causing widespread power outages.

Now for the good news? Sunday and early next week looks magical, weather-wise.
