SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
530 PM EDT WED JUN 5 2002

...HEAVY RAINS POSSIBLE TONIGHT THROUGH THURSDAY NIGHT...

A SLOW MOVING COLD FRONT WILL BE THE FOCUS FOR SOME HEAVY SHOWERS
AND THUNDERSTORMS FROM NOW THROUGH THURSDAY NIGHT.  ALTHOUGH THE
FRONT IS STILL WELL TO OUR NORTH AND WEST...HEAVY THUNDERSTORMS HAVE
ALREADY DEVELOPED OVER CENTRAL PENNSYLVANIA IN THE VERY MOIST AND
UNSTABLE AIR MASS AHEAD OF THE FRONT.  ALONG WITH LOCALLY HEAVY
RAINS...THE STRONGER THUNDERSTORMS COULD PRODUCE GUSTY WINDS AND
HAIL AS THEY MOVE EASTWARD ACROSS THE MID-ATLANTIC REGION THIS
EVENING.

THE GREATEST THREAT FOR MORE WIDE-SPREAD HEAVY RAINFALL APPEARS TO
BE ON THURSDAY AND THURSDAY NIGHT...AS THE COLD FRONT MOVES SLOWLY
SOUTH THROUGH EASTERN PENNSYLVANIA..NEW JERSEY AND EVENTUALLY INTO
THE DELMARVA. CONVERGING WINDS NEAR THE FRONT WILL FOCUS SHOWERS AND
THUNDERSTORMS ON EITHER SIDE AS AREAS OF LOW PRESSURE MOVE EAST
ALONG IT. BECAUSE OF THE SLOW FRONTAL MOVEMENT...MULTIPLE STORMS MAY
TEND TO MOVE OVER THE SAME AREAS WHICH COULD RESULT IN VERY HEAVY
RAINFALL ACCUMULATION AND EVEN POSSIBLY SOME FLOODING. FLOODING CAN
OCCUR EVEN THOUGH WE CONTINUE TO EXPERIENCE OVERALL DROUGHT
CONDITIONS AND WE NEED THE RAIN.

THE RAIN SHOULD BE OVER BY FRIDAY EXCEPT FOR SOME LINGERING MORNING
SHOWERS ALONG THE COAST.

PLEASE LISTEN FOR LATER FORECASTS AND STATEMENTS OVER THE NOAA
WEATHER RADIO...OR VISIT OUR WEB SITE AT WWW.NWS.NOAA.GOV/ER/PHI.
