Philadelphia, PA – Life-threatening heat is set to blanket the Philadelphia region on Friday, with heat indices soaring to 105°F and severe thunderstorms threatening the evening commute. Residents across Pennsylvania, New Jersey, and Delaware are urged to take action as the National Weather Service issues an Extreme Heat Watch and Heat Advisory, with warnings in effect from 10 a.m. until 8 p.m. Friday.
According to the National Weather Service in Mount Holly, dangerously hot and humid conditions will put many at risk for heat-related illnesses, especially the elderly and those without access to air conditioning. Scattered severe thunderstorms are possible Friday afternoon and evening, with damaging wind gusts, large hail, and brief heavy downpours likely—particularly for counties along the I-95 corridor, including Philadelphia, Wilmington, Trenton, and Allentown.
Coastal communities face additional risks, as a Coastal Flood Advisory is in effect for the Delaware Bay shore and tidal Delaware River during Thursday night’s high tide. Localized flooding may occur on low-lying roads and near vulnerable shorelines.
Stay indoors during peak heat, hydrate frequently, and check on neighbors. Limit travel during storms, secure loose outdoor items, and charge electronic devices in advance.
This combination of dangerous heat and storms is rare for late July. More showers and storms are likely over the weekend, though temperatures will moderate slightly. Weather alerts remain in effect through Friday evening, with updates possible as conditions evolve.
