New Jersey residents are facing a dangerous combination of extreme heat, suffocating humidity, and a growing threat of violent thunderstorms — all on the same day.
The National Weather Service has issued a severe thunderstorm watch for 16 counties across the state, active through 11 p.m. Friday night. The watch covers Burlington, Camden, Essex, Gloucester, Hunterdon, Mercer, Middlesex, Monmouth, Morris, Ocean, Passaic, Salem, Somerset, Sussex, Union, and Warren counties.
Forecasters warn that isolated thunderstorms could produce damaging winds of up to 70 mph — strong enough to down trees, knock out power lines, and cause significant property damage.
Temperatures across the state climbed into the low 90s by mid-morning Friday and shot into the upper 90s to low 100s by mid-afternoon. Several locations — including Atlantic City International Airport, Cape May Court House, East Brunswick, New Brunswick, and Woodland Township — recorded highs of 104 degrees, tying a historical record last set in 1966.
But the thermometer isn’t the only concern. Sky-high humidity is making it feel as hot as 110 to 115 degrees in many parts of the state, according to forecasters. That level of heat index poses a serious risk of heat exhaustion and heat stroke, especially for elderly residents, young children, and those working outdoors.
Forecasters explained that the extreme heat and thick humidity are creating severe atmospheric instability — the same conditions that allow powerful thunderstorms to develop rapidly and without much warning during late afternoon and evening hours.
Residents in the affected counties are urged to stay indoors during peak heat hours, keep air conditioning running, check on neighbors and elderly family members, and avoid being outside when storms begin to develop.
The relief many are hoping for on the Fourth of July weekend will not arrive as expected. Temperatures on Saturday are projected to climb back into the upper 90s, and forecasters say another chance of severe thunderstorms exists during the afternoon and evening hours.
Officials have not yet issued any evacuation orders but are monitoring conditions closely. Residents are advised to stay weather-aware and have a plan ready in the event of power outages or downed trees near their homes.
