An extreme heat watch has been issued across most of New Jersey, with forecasters warning that dangerous heat and humidity could make it feel like 110 degrees for multiple days this week — raising serious concerns about public safety heading into the Fourth of July holiday.
The National Weather Service confirmed Sunday that confidence is increasing in a multi-day heat event stretching from Wednesday through the holiday weekend, with high temperatures expected to reach the mid-90s to as high as 105 degrees. Heat index values — the “feels like” temperature when humidity is factored in — could soar between 100 and 110 degrees.
Which counties are under the watch?
The extreme heat watch covers 16 counties across the state. Bergen, Essex, Hudson, Passaic, and Union counties are currently excluded, as they fall under a separate National Weather Service office.
Day-by-day breakdown
The week starts relatively mild. Sunday will see isolated showers with highs in the upper 70s to mid-80s. Monday and Tuesday remain mostly dry, with temperatures gradually climbing from the mid-80s into the low 90s.
The real danger arrives Wednesday, when temperatures are forecast to surge into the mid- to upper-90s. By Thursday and Friday, the heat peaks — with highs potentially touching 105 degrees and rising humidity making conditions increasingly hazardous.
Overnight lows will offer almost no relief, with temperatures staying in the 80s in urban areas Thursday and Friday nights — a major health risk, especially for elderly residents and young children.
Saturday, July 4th, brings highs near 100 degrees, along with a growing chance of severe thunderstorms through the weekend.
Multiple temperature records could fall
Forecasters say records set on July 2 and July 3 could be broken this year. The heat is expected to gradually ease by Sunday, though highs will still remain in the upper 80s to mid-90s.
Residents are urged to stay hydrated, avoid outdoor activity during peak afternoon hours, and check on vulnerable neighbors as this dangerous heat event approaches.
