Newark, NJ – A migrating heat dome is set to drive temperatures into the 80s across New Jersey within days, creating early-season heat stress while repeated rounds of rain threaten travel disruptions through the first full week of April.
According to the National Weather Service Climate Prediction Center, a 70 to 80 percent probability of above-normal temperatures will dominate New Jersey from April 3 through April 9 as a strong ridge of high pressure shifts east. Highs in Newark, Trenton, and Camden are expected to run 10 to 20 degrees above seasonal averages, with warm overnight lows limiting relief.
The heat dome expands across the Mid-Atlantic, with even hotter air pushing into the Southeast where temperatures may reach the upper 90s. In New Jersey, the state sits along the northern edge of this system, where humidity and daytime heating will trigger repeated showers and thunderstorms.
Rain chances increase statewide, particularly during afternoon and evening hours. Heavier downpours could impact major routes including the New Jersey Turnpike, Garden State Parkway, and I-78, leading to reduced visibility and ponding on roadways.
Residents are urged to stay hydrated, limit strenuous outdoor activity during peak heat, and avoid driving through flooded roadways.
This heat-driven pattern will hold through April 9, with additional advisories likely as storm timing and rainfall totals become more defined.
