KEY MESSAGE 1...A RELATIVELY BENIGN STRETCH OF WEATHER IS
EXPECTED FOR THE NEXT WEEK.
WINDS EARLY THIS EVENING REMAIN GUSTY OUT OF THE NORTH-NORTHWEST,
WITH GUSTS 25-35 MPH. THE WIND WILL DIMINISH AS WE GO THROUGH
TONIGHT.
A SURFACE HIGH REMAINS IN CONTROL THROUGH THE END OF THE WEEK.
A COLD FRONT PASSES ON FRIDAY NIGHT, BUT SHOULD MOVE THROUGH DRY
WITH ANOTHER STRONG AREA OF HIGH PRESSURE MOVING IN FOR THE
WEEKEND. THE ONLY NOTICEABLE IMPACT WITH THE FRONTAL PASSAGE
WILL BE SOME GUSTY WINDS ESPECIALLY ON SATURDAY WITH PEAK GUSTS
25-35 MPH.
AN OMEGA BLOCK SETS UP OVER THE CENTRAL U.S., WITH OUR AREA
BEING POSITIONED ON THE EASTERN SIDE OF THE BLOCK. SEVERAL
DISTURBANCES TRY TO ROTATE IN, BUT SHOULD STAY MORE OFF TO THE
NORTHEAST WITH THE ONLY SENSIBLE IMPACT BEING SOME MORE
CLOUDINESS AT TIMES AND TEMPERATURES A FEW DEGREES BELOW NORMAL
FROM SATURDAY ONWARD.
THAT CHANGES A BIT AS A SHORTWAVE TRYING TO CUTOFF GETS CLOSER
TO OUR AREA FOR NEXT WEEK. THIS COULD RESULT IN AN UNSETTLED
PATTERN BUT CONFIDENCE IS LOW ON WHERE EXACT FEATURES SET UP.
HOWEVER, THE RISK FOR HAZARDOUS AND IMPACTFUL WEATHER IS LOW.
OVERALL, IT WILL BE QUITE PLEASANT AS WE BARREL TOWARDS
METEOROLOGICAL SUMMER WITH NO SIGNIFICANT IMPACTS EXPECTED.

RIP CURRENTS...
FOR FRIDAY, A NORTHWEST WIND 10-15 MPH WILL BECOME WEST AND
THEN SOUTHWEST AS MORE OF A SEA BREEZE DEVELOPS DURING THE
AFTERNOON. A MEDIUM PERIOD 7 TO 8 SECOND SWELL AND BREAKING
WAVES IN THE SURF ZONE OF 1-2 FEET ARE FORECAST. THIS WILL
RESULT IN A LOW RISK FOR THE DEVELOPMENT OF DANGEROUS RIP
CURRENTS FOR BOTH THE NEW JERSEY SHORE AND DELAWARE BEACHES.
FOR SATURDAY, NORTHWEST TO NORTH WINDS 15-20 MPH WITH GUSTS
25-35 MPH ARE FORECAST. BREAKING WAVES OF AROUND 2 FEET IN THE
SURF ZONE ALONG WITH A MEDIUM PERIOD 7 SECOND SWELL WILL CONTINUE
TO RESULT IN A LOW RISK FOR THE DEVELOPMENT OF DANGEROUS RIP
CURRENTS FOR BOTH THE NEW JERSEY SHORE AND DELAWARE BEACHES.
OCEAN WATER TEMPERATURES ARE IN THE 50S TO LOW 60S. THESE
CHILLY WATER TEMPERATURES CAN QUICKLY CAUSE HYPOTHERMIA AND
