DISCUSSION
KEY MESSAGE 1...GUSTY WINDS BEHIND A DRY COLD FRONT EXPECTED
SATURDAY.
AN AREA OF LOW PRESSURE IS EXPECTED TO DIVE THROUGH NEW ENGLAND
TONIGHT, AND WILL DRAG A COLD FRONT THROUGH OUR REGION
OVERNIGHT. THIS SHOULD BE A DRY FRONTAL PASSAGE THOUGH AS
MOISTURE OVER OUR AREA IS LACKING, BUT A NOTICEABLE UPTICK IN
WINDS IS EXPECTED BEHIND THE FRONT. THE RESULT WILL BE A BREEZY
SATURDAY ACROSS THE REGION.
WIND GUSTS OUT OF THE NORTH/NORTHWEST WILL BE STRONGEST AFTER
DAYBREAK SATURDAY. GUSTS UPWARD OF 25 TO 35 MPH WITH PEAK GUSTS
AROUND 40 MPH ARE ANTICIPATED. GUSTS WILL GRADUALLY DIMINISH BY
THE MID-AFTERNOON AND INTO THE EARLY EVENING.
THE ONE PLACE WHERE GUSTS COULD BE A BIT HIGHER WILL BE OVER
THE SOUTHERN POCONOS. THE CURRENT FORECAST HAS GUSTS GETTING
CLOSE TO WIND ADVISORY CRITERIA ON SATURDAY MORNING BUT HAVE
ELECTED TO HOLD OFF ON ANY HEADLINES FOR NOW. BOTH THE NBM AND
HREF PROBABILITY OF GUSTS OVER 40 KT (WIND ADVISORY CRITERIA)
ARE AROUND 40%. WHILE MOST OF THE REGION WILL SEE GUSTS MAINLY
IN THE 30S, SOME AREAS IN THE POCONOS COULD GET ABOVE 40 MPH ON
SATURDAY MORNING.
OUTSIDE OF GUSTY WINDS, IT WILL BE A QUIET WEEKEND WITH A DRY
WEATHER AND TEMPERATURES A FEW DEGREES BELOW NORMAL, BUT STILL
PLEASANT AS WE GET TOWARDS METEOROLOGICAL SUMMER.
KEY MESSAGE 2...POTENTIALLY UNSETTLED FOR NEXT WEEK WITH
MULTIPLE DAYS OF SHOWER CHANCES.
IN GENERAL, UPPER-LEVEL TROUGHING WILL REMAIN IN PLACE OVER
MUCH OF THE NORTHEASTERN US THROUGH EARLY NEXT WEEK. BY MID-
WEEK, AN UPPER- LOW IS EXPECTED TO BEGIN TO CLOSE OFF, BEFORE
TRACKING SLOWLY NORTHEASTWARD AWAY FROM THE COAST. AT THE
SURFACE, A WEAK COLD FRONT IS EXPECTED TO PASS THROUGH THE
REGION ON MONDAY. A SURFACE LOW WILL LIKELY FORM IN ASSOCIATION
WITH THE CLOSED UPPER-LOW OFF THE COAST AS IT PULLS AWAY.
THE FIRST CHANCE FOR SHOWERS AND PERHAPS A STORM OR TWO WILL BE
ON MONDAY WITH THE PASSAGE OF THE WEAK FRONT. CHANCES WILL BE
GREATEST ACROSS THE EASTERN HALF OR SO OF THE AREA, CURRENTLY
RANGING FROM 20- 40%. NO SIGNIFICANT IMPACTS ARE EXPECTED.
TUESDAY AND BEYOND, THE PATTERN LOOKS TO REMAIN UNSETTLED,
THOUGH THERE ARE DISCREPANCIES IN GUIDANCE AS TO HOW CLOSE TO
THE COAST THE LOW WILL GET DUE IN PART TO STRONG HIGH PRESSURE
BUILDING IN FROM THE NORTHWEST. REGARDLESS, A 20-40% CHANCE OF
SHOWERS EXISTS OVER MUCH OF THE AREA THROUGH WEDNESDAY BEFORE
THE LOW BEGINS TO PULL AWAY ON THURSDAY, WITH HIGH PRESSURE
SETTLING IN THEREAFTER.
TEMPERATURES THROUGH WEDNESDAY LOOK TO BE FAIRLY CLOSE TO
SEASONAL NORMS ACROSS THE AREA, WITH HIGHS GENERALLY IN THE MID
70S AND LOWS IN THE MID 50S. A WARMING TREND MAY BEGIN THURSDAY
INTO FRIDAY.

RIP CURRENTS...
FOR TODAY, 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 TO 3 FEET IN
THE SURF ZONE ALONG WITH A MEDIUM PERIOD 5 TO 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
