• High temperatures will soar into the 90s across most inland areas, with a heat index potentially at 100+ degrees — “dangerous heat” territory.
• A Heat Advisory has been issued for most of the state, with temperatures expected to reach 90 to 95 degrees.
• A Flood Watch has been issued for all 21 counties of New Jersey, cautioning that downpours may cause flash flooding of low-lying areas and other flood-prone areas, including roadways.

Tuesday promises to be an active, uncomfortable, and potentially nasty weather day across New Jersey. The combination of high temperatures and high humidity will create a “dangerous heat” situation, with the heat index potentially reaching 103 degrees. The heat advisory will be in effect from 10 a.m. to 8 p.m., so it’s essential to take precautions to stay cool and safe. Dressing for the heat is crucial, with loose-fitting, light-colored clothing recommended. Limiting strenuous activity during the hottest part of the day, taking frequent breaks in air conditioning, and staying hydrated are also vital. Knowing the signs of heat exhaustion and stroke and taking action if needed is crucial. The Jersey Shore will provide some relief from the heat, but beachgoers should be aware of the high risk of rip currents and rough surf. Following all posted flags, signs, and lifeguard instructions is essential. The main concern for Tuesday is a round of strong thunderstorms expected to develop later in the day, bringing damaging winds, heavy rain, and lightning. The storm activity is expected to peak around dinnertime, coinciding with the evening commute, which could become very treacherous in spots. A Flood Watch has been issued for all 21 counties, with downpours potentially causing flash flooding in low-lying areas and other flood-prone areas. Wednesday will see a continued steamy weather, with the heat index falling out of the “danger zone.” The sky will be mostly cloudy, with a chance of showers at any time. High temperatures will reach the upper 80s to around 90 degrees, which is above normal for this time of year. Thursday is a question mark, with unsettled weather expected. The forecast models are leaning towards a wetter solution, with a chance of even more rain during the day. A mainly dry day would see seasonable highs in the mid 80s, while a wetter day would be closer to 80 degrees. Friday will not be a perfect weather day, but it’s expected to improve, with early clouds and a few stray showers giving way to partial sunshine. A thunderstorm is possible later on, but it should be isolated. The weekend is looking typical, with a partly sunny day on Saturday and a chance for an isolated shower or thunderstorm. High temperatures in the upper 80s to around 90 are expected.
