The National Weather Service has issued a tornado watch for part of the Philadelphia region as a line of thunderstorms with the potential to spawn twisters bears down on the area.

The storms are remnants of a weather system that led to tornadoes in the Midwest.

The watch, which is in effect until 10 p.m., covers most of Pennsylvania and Gloucester, Camden, Burlington, Warren, Hunterdon, and Mercer Counties in New Jersey.

The National Weather Service said the storms expected Tuesday afternoon and evening could have “locally damaging winds and large hail.”

A tornado watch means conditions are favorable for the development of tornadoes in and close to the watch area.

Overall, the short work week looks like it will be mostly wet, with showers or thunderstorms in the forecast through Friday morning.

In an updated hazardous weather outlook statement, the weather service said, “Scattered strong to severe thunderstorms are possible late in the day both Wednesday and Thursday.”

The daytime high temperatures will be around 81 degrees Tuesday, in the mid 80s Wednesday and Thursday, and in the upper 70s on Friday, according to the weather service’s forecast.

It should be mostly sunny with a high around 80 on Saturday, but there’s a chance of showers and thunderstorms again Sunday.
