Isolated severe thunderstorms possible tomorrow

Thunderstorms are possible tomorrow as a cold front approaches from the west and enters an area of atmospheric instability, forecasters say. 

The activity could develop in two phases, arriving first in the morning and then again during the afternoon following a period of sunshine, according to the National Weather Service office in Mount Holly, NJ.

The scattered thunderstorms could produce gusty winds, and some might reach severe levels. 

The National Weather Service’s Storm Prediction Center places the area in the “marginal risk” category for severe thunderstorm development, meaning a chance of “severe storms of either limited organization and longevity, or very low coverage and marginal intensity.”

NOAA defines a severe thunderstorm as producing hail at least one of the following: hail at one-inch in diameter, a wind gust of 58 miles per hour or greater, or a tornado.
