Severe Thunderstorm Watch Added for Much of New Jersey as Dangerous Heat Continues

New Jersey’s weather risk climbed again Friday night, July 3, 2026, as a Severe Thunderstorm Watch was added for much of the state while dangerous heat continued heading into the holiday weekend.

The National Weather Service office in Mount Holly said Friday evening that Severe Thunderstorm Watch 448 was in effect until 11 p.m. for “all but extreme southeast New Jersey.” That update came as forecasters warned that dangerous heat and humidity will continue through Saturday across much of the region.

The setup matters because this is not just a routine summer storm chance. The same air mass that pushed heat index values into dangerous territory is also helping fuel storms that could turn severe. The National Weather Service said damaging wind gusts are the main threat with thunderstorm development, and its Friday afternoon weather briefing said a severe thunderstorm watch had been issued for much of the area until 11 p.m.

Forecast pages for New Jersey locations including Jersey City and Cherry Hill showed multiple hazards in effect Friday night, including the severe thunderstorm watch and ongoing heat alerts. In practical terms, that means residents need to be ready for fast-changing conditions: oppressive heat, scattered storms, and the possibility that one warning could quickly turn into another.

Anyone spending time outside for July 4 events, travel, backyard gatherings, or fireworks plans should keep an especially close eye on live warnings Friday night and again Saturday. If a severe thunderstorm warning is issued for your area, move indoors immediately and stay away from windows. With the heat still in place into Saturday evening, it is also important to limit strenuous outdoor activity, stay hydrated, and check on older adults, young children, and anyone without reliable air conditioning.
