SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1058 AM EDT TUE JUL 23 2002

...A SLIGHT RISK OF SEVERE THUNDERSTORMS EXISTS THIS AFTERNOON INTO 
TONIGHT OVER EASTERN PENNSYLVANIA AND NEW JERSEY...

...STRONG THUNDERSTORMS ARE ALSO POSSIBLE OVER DELAWARE AND 
NORTHEASTERN MARYLAND LATE TODAY AND TONIGHT...

A COLD FRONT WILL APPROACH THE REGION FROM THE NORTHWEST THIS 
MORNING...MOVING SOUTHEAST AND INTO THE AREA LATER THIS AFTERNOON 
AND TONIGHT. THUNDERSTORMS ARE EXPECTED TO DEVELOP FIRST OVER 
NORTHEASTERN PENNSYLVANIA AND NORTHERN NEW JERSEY DURING THIS 
AFTERNOON AND CONTINUE INTO EARLY TONIGHT.

SHOWERS AND THUNDERSTORMS WILL SPREAD SOUTHWARD OVER EXTREME 
SOUTHERN NEW JERSEY...DELAWARE...AND NORTHEASTERN MARYLAND LATE IN 
THE DAY AND EARLY TONIGHT...AND CONTINUING INTO THE OVERNIGHT PERIOD 
AS THE FRONT SETTLES SOUTHWARD.

DUE TO THE HIGH INSTABILITY ASSOCIATED WITH THE HEAT AND HUMIDITY OF 
THE AIRMASS NOW IN PLACE...SOME OF THESE THUNDERSTORMS COULD BECOME 
SEVERE. 

THEREFORE THE STORM PREDICTION CENTER HAS FORECAST A SLIGHT RISK OF 
SEVERE THUNDERSTORMS FOR EASTERN PENNSYLVANIA AND NORTHERN AND 
CENTRAL NEW JERSEY FOR THIS AFTERNOON AND TONIGHT. THUNDERSTORMS 
OVER SOUTHERN NEW JERSEY...DELAWARE...AND NORTHEASTERN MARYLAND LATE 
TODAY AND TONIGHT MAY ALSO BECOME QUITE STRONG. 

THE PRIMARY THREATS FROM ANY THUNDERSTORMS THIS AFTERNOON AND 
TONIGHT WILL BE STRONG WIND GUSTS...FREQUENT LIGHTNING...LARGE 
HAIL...AND HEAVY RAINS. IN FACT...DUE TO THE HIGH AMOUNT OF MOISTURE 
THROUGH A DEEP LAYER OF THE ATMOSPHERE...SOME THUNDERSTORMS MAY 
PRODUCE AS MUCH AS THREE OR FOUR INCHES OF RAIN IN A SHORT TIME...SO 
LOCALIZED FLOODING OF ROADS AND LOW SPOTS IS LIKELY.

IF YOU OBSERVE THREATENING WEATHER...SEEK SHELTER AT ONCE.

STAY TUNED TO NOAA WEATHER RADIO AND OTHER LOCAL MEDIA FOR FURTHER
DETAILS OR UPDATES.
