SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
940 AM EDT WED AUG 27 2003

...A FEW SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON INTO EARLY
THIS EVENING...

A COLD FRONT WILL APPROACH THE REGION THIS AFTERNOON...AND SETTLE
SOUTH OF THE AREA THIS EVENING. A DISTURBANCE MOVING ACROSS
PENNSYLVANIA WILL TRACK EAST SOUTHEASTWARD TODAY. THIS WILL ACT UPON
THE WARM AND HUMID AIRMASS THAT REMAINS IN PLACE OUT AHEAD OF THE
COLD FRONT. AS A RESULT...SOME SHOWERS AND THUNDERSTORMS ARE
ANTICIPATED THIS AFTERNOON INTO THIS EVENING.

A FEW STORMS COULD TURN SEVERE AND PRODUCE DAMAGING WINDS AND
HAIL...ALONG WITH FREQUENT CLOUD TO GROUND LIGHTNING. ANY
THUNDERSTORMS THAT DO DEVELOP WILL ALSO BE CAPABLE OF PRODUCING
HEAVY DOWNPOURS. THE BEST CHANCE FOR ORGANIZED SEVERE THUNDERSTORMS
SHOULD BE FROM ABOUT THE PHILADELPHIA METROPOLITAN AREA SOUTHWARD.

IF THREATENING WEATHER APPROACHES YOUR LOCATION...SEEK SHELTER
IMMEDIATELY. WHILE OUTDOORS...KEEP AN EYE TO THE WESTERN SKY AND
ALLOW YOURSELF ENOUGH TIME TO REACH A SAFE LOCATION IF THUNDERSTORMS
APPROACH YOUR AREA. IF TRAVELING...BE PREPARED FOR SOME LOCALLY
HEAVY DOWNPOURS THIS AFTERNOON AND SLOW DOWN AS VISIBILITIES CAN BE
GREATLY REDUCED IN DOWNPOURS.

STAY TUNED TO NOAA WEATHER RADIO OR LOCAL MEDIA OUTLETS FOR FURTHER
STATEMENTS AND ANY POSSIBLE WARNINGS.
