Philadelphia, Pennsylvania – Residents across southeastern Pennsylvania, New Jersey, Delaware, and northeastern Maryland should prepare for a combination of dangerous heat and severe thunderstorms throughout Thursday. Heat index values are expected to climb to 95-100 degrees Fahrenheit, particularly south of Interstate 78.
According to the US National Weather Service Philadelphia/Mount Holly, scattered severe thunderstorms are anticipated this afternoon and evening. Damaging winds pose the primary threat, though large hail and an isolated tornado cannot be ruled out.
Cities like Philadelphia, Wilmington, Dover, and Vineland will experience the most significant heat impacts. Staying hydrated by drinking plenty of water and seeking air-conditioned spaces or shade is crucial. Outdoor activities should be limited, especially during peak afternoon hours. For those without reliable cooling, public cooling centers may be available; check with local emergency management for details.
The National Weather Service urges residents to secure loose outdoor objects and be ready for rapidly changing weather conditions. Similar heat and storm combinations have historically led to power outages and hazardous travel conditions.
Warnings and advisories for dangerous heat and severe weather remain in effect through Thursday evening, with conditions expected to ease slightly overnight. Monitor local news and weather alerts for further updates.
