NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
718 PM EDT FRI AUG 1 2025
SYNOPSIS
HIGH PRESSURE BUILDS IN FROM THE NORTH INTO THE WEEKEND, WITH
BELOW NORMAL TEMPERATURES, MUCH DRIER AND PLEASANT CONDITIONS
EXPECTED INTO EARLY NEXT WEEK. THE HIGH PRESSURE WILL BEGIN TO
SLIDE OFFSHORE INTO THE MIDDLE TO END OF NEXT WEEK WITH MORE
UNSETTLED WEATHER ARRIVING.
NEAR TERM /THROUGH SATURDAY/
OUR BROAD OFFSHORE LOW WILL CONTINUE GRADUALLY SHIFTING AWAY
FROM THE COAST AS COOL HIGH PRESSURE BUILDS IN FROM THE NORTH.
A LINGERING SHOWER OR LIGHT PATCHY DRIZZLE ALONG THE COAST WILL
MOVE OUT EARLY THIS EVENING AS SKIES BEGIN TO CLEAR FROM WEST
TO EAST.
COOL TEMPERATURES WILL CONTINUE TO DOMINATE TONIGHT ALONG WITH
DRIER CONDITIONS EXPECTED, LESSENING WINDS, AND CLEARING SKIES.
LOW TEMPERATURES WILL RANGE FROM THE MID 50S UP NORTH TO THE MID
60S CLOSER TO THE COAST AND IN THE URBAN CORRIDOR. A LIGHT
NORTH TO NORTHEAST BREEZE WILL CONTINUE.
FOR SATURDAY, HIGH PRESSURE CENTERS ITSELF OVER THE GREAT
LAKES, CONTINUING TO PROVIDE A LIGHT N TO NNE FLOW OF COOL AIR.
SUNNY AND DRY CONDITIONS WITH LOW HUMIDITY WILL MAKE FOR A
FANTASTIC DAY. AFTERNOON HIGH TEMPERATURES WILL CONTINUE BEING
BELOW CLIMO WITH UPPER 70S TO LOW 80S ACROSS THE NORTH AND WEST
AND LOW 80S FURTHER SOUTH AND EAST, INCLUDING THE URBAN
CORRIDOR.
SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/
THE NICE WEATHER CONTINUES FOR THE REMAINDER OF THE WEEKEND AS
A HIGH PRESSURE SYSTEM MOVES INTO THE NORTHEAST FROM THE GREAT
LAKES. THIS WILL LEAD TO MINIMAL CLOUD COVER SATURDAY NIGHT
THROUGH SUNDAY NIGHT WITH DRY WEATHER CONTINUING. IT WILL ALSO
BE COOLER AND MORE COMFORTABLE WITH DEW POINTS MAINLY IN THE
UPPER 50S AND HIGH TEMPERATURES ON SUNDAY IN THE LOW TO MID 80S.
LONG TERM /MONDAY THROUGH FRIDAY/
THE NICE WEATHER CONTINUES FOR MONDAY AND TUESDAY WITH DRY
CONDITIONS. MONDAY LOOKS TO FEATURE A LOT OF SUNSHINE WITH A FEW
MORE CLOUDS ON TUESDAY LEADING TO MORE OF A PARTLY SUNNY DAY.
TEMPERATURES AND DEWPOINTS START TO INCREASE ON MONDAY AND
TUESDAY. TEMPERATURES ARE MAINLY IN THE 80S BOTH DAYS WITH
DEWPOINTS INCREASING BACK INTO THE 60S ON TUESDAY WITH THE
HUMIDITY CREEPING UP.
BY THE SECOND HALF OF THE WEEK, UPPER-LEVEL TROUGHING BUILDS IN
AND WE GET MORE UNSETTLED. FOR AREAS SOUTH AND WEST ON
WEDNESDAY, THERE IS A SLIGHT CHANCE FOR A STRAY SHOWER. COVERAGE
WILL START TO INCREASE A BIT ON THURSDAY AND FRIDAY. WE START
TO SEE THE POTENTIAL FOR ISOLATED TO THEN SCATTERED SHOWERS,
ESPECIALLY ON THURSDAY INTO FRIDAY FOR SOUTHERN AREAS. THERE IS
ALSO THE POTENTIAL FOR ISOLATED THUNDERSTORMS. TEMPERATURES FOR
THE SECOND HALF OF THE WEEK WILL MAINLY BE IN THE MID 70S TO MID
80S EACH DAY. DEWPOINTS WILL START TO CLIMB WELL INTO THE 60S
FOR SOME SPOTS, SO WE REALLY START TO NOTICE THE HUMIDITY AGAIN.
