Northern and North Central New Jersey is under an unusual moderate risk designation for severe thunderstorms.

Damaging to destructive wind gusts appear to be the highest threat this evening into tonight. The thunderstorms will develop to our west and north and move east-southeast. At this point...most areas of NJ will see storms after 5 p.m. with the NW areas getting to see them possibly before the sun sets...hence the highest percentage of severe t-storms today in that area.

Some large hail cannot be ruled out...along with an isolated tornado.

A slight risk has now been issued for the rest of NJ...and with this heat...instability will linger into tonight to allow thunderstorms to persist after dark for a few hours.
