Severe thunderstorm warning for North Jersey this Thursday
Thursday, July 4 — NEW YORK – A severe thunderstorm warning is currently in effect for Warren and Sussex County, in northern New Jersey, where strong storms are moving through this Thursday afternoon. The National Weather Service issued the alert just after 3:30 p.m., warning residents in communities including Newton, Hopatcong, Franklin, Hamburg, Ogdensburg, Branchville, Lake Mohawk, and Crandon Lakes to remain alert until 4:15 p.m.
A broader severe thunderstorm watch is also active until 10:00 p.m., impacting multiple North and Central Jersey counties: Bergen, Essex, Hudson, Hunterdon, Middlesex, Morris, Passaic, Somerset, Sussex, Union, and Warren.
Forecasters highlight hail up to 2 inches in diameter, wind gusts reaching 70 mph, and frequent lightning strikes as the main threats.
“Today’s storms are much more isolated compared to Tuesday,” noted the National Weather Service earlier this morning. “Localized thunderstorms are possible, especially north and east of Philadelphia. Some areas will be hit while others won’t see a drop of rain.”** Those spending time outdoors are urged to stay aware, as conditions may change suddenly during the late afternoon and evening.
Storms are expected to weaken quickly after sunset, leaving much of the state with clear skies overnight.
Meanwhile, temperatures across New Jersey remain high, with afternoon highs near 90°F (32°C) across South and Central Jersey. Conditions are mostly sunny, apart from scattered storm cells in the northern region.
By Independence Day, the forecast improves significantly: dry skies, moderate temperatures, and comfortable humidity levels will make Friday the most pleasant day of the week.
