It's the last day of intense heat for the area as a Bermuda high that has been parked off the coast acting as a heat pump weakens  and moves to the south and east allowing a weak upper air disturbance to move through. There is an increased chance of showers & thunderstorms tonight through Wednesday.

A Heat Advisory is in effect for most of New Jersey  through 8 p.m. Sunday as temperatures in the 90s and high dew points combine for a heat index temperature of 100 degrees.

Mercer, Gloucester, Camden and Burlington counties are specifically under an Excessive Heat Watch as temperature will feel at least 102 degrees.

Salem, Atlantic, Cape May & Cumberland counties are not under an advisory but it will be nearly as hot and humid in those areas as well.

If you are spending any time outdoors it is recommended that you drink plenty of fluids, stay out of the sun and check on relatives and neighbors.
