The Philadelphia region is bracing for a bout of severe weather on Sunday evening, with forecasters warning of destructive thunderstorms, high winds, and even a low risk of a tornado. The storms are expected to hit between 7 and 11 PM, with rain continuing overnight into Monday morning.

Why it matters

Severe storms can cause significant property damage, power outages, and pose a threat to public safety. The Philadelphia area has seen its share of intense weather events in recent years, and this latest system has the potential to disrupt travel and daily life for residents.

The details

According to NBC10 First Alert Meteorologist Justin Godynick, the severe weather is being driven by a combination of warm temperatures on Sunday and a cold front moving through the region in the evening. While the main threats are damaging winds and thunderstorms, there is also a very low risk of a tornado, especially in areas west of the Delaware River.

  • Sunday will start off mostly sunny and very warm, with highs in the lower 70s.
  • The severe storms are expected between 7 and 11 PM on Sunday evening.
  • Rain will continue overnight into Monday morning, before departing around the morning commute.
  • On Monday, the sun will return but winds will increase to around 30 mph, and temperatures will drop from the mid-50s into the 40s.
