IN NEW JERSEY IT INCLUDES BURLINGTON...CAMDEN...GLOUCESTER...HUNTERDON... MERCER...MIDDLESEX...MONMOUTH...MORRIS...OCEAN...SOMERSET... SUSSEX AND WARREN. A LINE OF THUNDERSTORMS OVER CENTRAL NEW YORK AND WESTERN PENNSYLVANIA IS EXPECTED TO INTENSIFY AS IT MOVES INTO THE UNSEASONABLY HOT AND HUMID AIR MASS OVER THE REGION.

REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE FAVORABLE FOR THE DEVELOPMENT OF THUNDERSTORMS WHICH CONTAIN DAMAGING WIND IN EXCESS OF 55 MPH AND HAIL 3/4 INCH OR GREATER IN DIAMETER IN AND CLOSE TO THE WATCH AREA. FREQUENT LIGHTNING AND VERY HEAVY RAIN WILL ALSO ACCOMPANY THESE THUNDERSTORMS. SKYWARN ACTIVATION IS REQUESTED. TFG
