Philadelphia, PA – Residents across southeastern Pennsylvania, central and southern New Jersey, Delaware and northeastern Maryland could face strong to potentially severe thunderstorms Thursday afternoon, Nov. 12, as a strengthening low pressure system moves through the region. Damaging winds and large hail are the primary threats, although forecasters say an isolated tornado cannot be ruled out.
According to the National Weather Service in Philadelphia/Mount Holly, the approaching storm system is expected to strengthen as it crosses the region Thursday, creating conditions favorable for a few thunderstorms capable of reaching severe limits.
Thursday, Nov. 12: Severe Storm Risk Develops
The Storm Prediction Center has placed portions of the region under a Level 1 of 5, or Marginal Risk, for severe thunderstorms.
This designation means isolated severe storms are possible, but widespread severe weather is not currently expected.
The primary window for stronger thunderstorms is Thursday afternoon.
Philadelphia and South Jersey: Damaging Winds Possible
Philadelphia and surrounding southeastern Pennsylvania communities are included in the severe weather outlook.
Across New Jersey, areas near Trenton, Camden, Vineland and Atlantic City should monitor changing weather conditions as storms develop.
Damaging wind gusts could bring down tree limbs or cause isolated power disruptions if stronger thunderstorms form.
Delaware and Maryland: Hail, Tornado Potential
Wilmington, Dover and portions of northeastern Maryland are also within the broader severe weather risk area.
Large hail is possible with stronger thunderstorms, and the National Weather Service notes a nonzero risk of an isolated tornado.
However, the forecast does not indicate that a tornado is expected or that a tornado warning has been issued.
What Residents Should Know
Residents should monitor updated forecasts and ensure they can receive weather watches and warnings Thursday afternoon.
Outdoor activities may need to be adjusted if thunderstorms approach.
Anyone receiving a severe thunderstorm or tornado warning should follow official safety instructions immediately.
The National Weather Service will continue monitoring the system as it moves across the Mid Atlantic region.
