Thunderstorms that develop Monday afternoon and evening may become severe, forecasters say.
In response to the threat, a Severe Thunderstorm Watch is in place through 8 p.m. for all New Jersey counties, according to the National Weather Service.
“These storms will be capable of producing strong winds, dangerous lightning, small hail, and a few isolated tornadoes,” said John Homenuk, lead forecaster at New York Metro Weather.
Building instability, with a thermal gradient developing near the area and increased lift for thunderstorm formation, will help develop the threat, he said.
A severe thunderstorm watch means that the potential exists for the development of thunderstorms, which may produce large hail or damaging winds, according to NOAA. A severe thunderstorm warning, on the other hand, means that a severe thunderstorm is occurring or is imminent based on doppler radar information.
