DISCUSSION
KEY MESSAGE 1...ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS
DEVELOPS THIS AFTERNOON AND CONTINUES INTO THE EARLY EVENING.
A COLD FRONT IS CURRENTLY MOVING SOUTHWARD THROUGH OUR AREA AND
WILL BECOME NEARLY STATIONARY OVER OR JUST SOUTH OF DELMARVA
LATER THIS AFTERNOON. AN AREA OF LOW PRESSURE WILL RIDE ALONG
THE BOUNDARY, RESULTING IN WIDESPREAD SHOWERS AND SCATTERED
THUNDERSTORMS CONTINUING THROUGH THE PM HOURS.
NO CHANGES TO BOTH THE EXCESSIVE RAINFALL AND SEVERE WEATHER
OUTLOOK FOR TODAY. A MARGINAL RISK FOR EXCESSIVE RAINFALL IS IN
PLACE FROM I-80 ON SOUTH WITH A MARGINAL RISK FOR SEVERE WEATHER
FROM ABOUT I-78 SOUTHWARD. MORE INSTABILITY WILL DEVELOP OUT
AHEAD OF THE FRONT DUE TO DAYTIME HEATING, FOCUSING THE SEVERE
WEATHER THREAT ON THE SOUTHERN AREAS. SHEAR IS WEAK THOUGH STILL
SO A MARGINAL IS ABOUT RIGHT. SOME SOUNDINGS SHOW AN INVERTED
SIGNATURE AS WELL. THIS WILL RESULT IN THE PRIMARY THREAT FOR
TODAY BEING DAMAGING WIND GUSTS FOR THE SOUTHERN HALF OF THE
AREA. THE TIMING FOR THE STRONG TO SEVERE THUNDERSTORMS REMAINS
THROUGH ABOUT 8 PM, BUT SHOWERS COULD LINGER INTO THE FIRST
HALF OF THE NIGHT.
IN TERMS OF THE HYDRO THREAT, STILL SEEING PWATS TOWARDS THE
HIGHER CLIMATOLOGICAL PERCENTILES INDICATING A MUGGY AND MOIST
AIRMASS. PERIODS OF HEAVY RAIN ARE CERTAINLY POSSIBLE BUT
THINKING RAINFALL RATES WILL NOT BE AS IMPRESSIVE AS A FEW DAYS
AGO WHEN WE SAW SEVERAL INSTANCES OF FLASH FLOODING. STORMS
SHOULD ALSO BE MOVING JUST QUICKLY ENOUGH AND THERE ISN'T MUCH
OF A SIGNAL FOR TRAINING OR BACKBUILDING STORMS. THE MARGINAL
RISK FOR EXCESSIVE RAINFALL REMAINS IN PLACE, AND THINKING
FLOODING SHOULD BE LIMITED TO URBAN AREAS OR AREAS THAT HAVE
SEEN SIGNIFICANT RAINFALL OVER THE PAST 7 DAYS. OTHERWISE, WE
SHOULD CONTINUE TO MAKE INROADS ON THE CONTINUING RAINFALL
DEFICIT AND DROUGHT.
THE FRONT SHOULD FINALLY DROP SOUTH OF THE REGION BY TONIGHT,
WITH HIGH PRESSURE AND DRIER AIR WORKING IN. CANNOT RULE OUT
SOME PATCHY FOG TONIGHT ESPECIALLY OVER AREAS THAT SEE SOME
RAINFALL TODAY, THOUGH THE INCOMING DRY AIR SHOULD LIMIT THE FOG
THREAT A BIT.
KEY MESSAGE 2... DRIER CONDITIONS FOR SUNDAY AND INTO THE UPCOMING
WEEK. ABOVE NORMAL TEMPERATURES ARE EXPECTED FOR TUESDAY AND
ESPECIALLY WEDNESDAY.
BEYOND SATURDAY, THINGS TURN DRIER WITH AN EXPANSIVE AREA OF HIGH
PRESSURE MOVING IN. SOME SHORT RANGE GUIDANCE WANTED TO DEVELOP
SHOWERS OVER THE HIGHER TERRAIN IN THE POCONOS ON SUNDAY AFTERNOON,
BUT THINKING ANYTHING WILL BE VERY ISOLATED AND NON- IMPACTFUL.
OTHERWISE, IT WILL BE DRY ACROSS THE AREA THROUGH MID-WEEK.
SEASONABLE TEMPERATURES AND A PLEASANT STRETCH ARE EXPECTED FROM
SUNDAY THROUGH MONDAY. THE HEAT RETURNS FOR THE MIDDLE OF NEXT
WEEK AS RIDGING MOVES INTO THE MID-ATLANTIC. WEDNESDAY LOOKS TO
BE THE WARMEST DAY WITH TEMPERATURES POTENTIALLY GETTING WELL
INTO THE 90S AND HEAT INDICES FLIRTING WITH HEAT ADVISORY CRITERIA.
THE ABOVE NORMAL TEMPERATURES LOOK TO CONTINUE THROUGH THE END
OF THE WEEK, THOUGH A COLD FRONT MAY LOWER TEMPERATURES A SMIDGE
AT SOME POINT.
KEY MESSAGE 3...MINOR TIDAL FLOODING EXPECTED THIS WEEKEND FOR COASTAL
COMMUNITIES AND AREAS AROUND DELAWARE BAY. A COASTAL FLOOD ADVISORY
WAS ISSUED FOR THIS EVENING'S HIGH TIDE FOR MOST OF THE NEW
JERSEY COAST, DELAWARE COAST, AND AREAS SURROUNDING DELAWARE
BAY.
A RELATIVELY LIGHT ONSHORE FLOW SETS UP THROUGH THIS WEEKEND,
RESULTING IN A MINOR PUSH OF WATER TOWARDS THE COASTLINE.
ASTRONOMICAL TIDES ARE ALSO INCREASING WITH THE UPCOMING NEW MOON ON
TUESDAY. THIS WILL RESULT IN ELEVATED TIDES WITH MINOR TIDAL
FLOODING POSSIBLE BEGINNING WITH THE HIGH TIDE THIS EVENING.
GUIDANCE HINTS AT TIDAL FLOODING CONTINUING WITH THE
EVENING/NIGHTTIME HIGH TIDE CYCLES INTO EARLY NEXT WEEK BEFORE FLOW
TURNS MORE SOUTHERLY. HOWEVER, THERE WILL BE A STRONGER INFLUENCE OF
ASTRONOMICAL TIDES AS WE GET CLOSER TO THE NEW MOON WHICH COULD
KEEP ELEVATED TIDES THROUGH THE MIDDLE OF NEXT WEEK. THE AREAS
MOST AT RISK OF SEEING MINOR TIDAL FLOODING ARE ALONG THE
ATLANTIC OCEAN COASTLINE AND WITHIN DELAWARE BAY. THE SEVERITY
LOOKS TO REMAIN WITHIN MINOR LEVELS BUT WILL MONITOR HOW THINGS
TREND OVER THE COMING DAYS.
FOR THIS EVENING, TIDES LOOK TO BE HIGHEST ALONG THE NEW JERSEY
COAST, DELAWARE COAST, AND WITHIN DELAWARE BAY. A COASTAL FLOOD
ADVISORY REMAINS IN EFFECT FOR THESE AREAS WITH OCEAN,
MONMOUTH, AND SOUTHEASTERN BURLINGTON COUNTIES BEING ADDED FOR
THIS EVENING'S HIGH TIDE GIVEN TRENDS. THOSE AREAS MAY NEED AN
ADDITIONAL ADVISORY FOR SUNDAY NIGHT'S HIGH TIDE, BUT TOO EARLY
TO KNOW FOR CERTAIN.
CANNOT RULE OUT SOME SPOTTY MINOR TIDAL FLOODING FOR
COMMUNITIES ALONG THE DELAWARE RIVER WITH THE UPCOMING ELEVATED
TIDES. NO TIDAL FLOODING IS EXPECTED IN OUR EASTERN SHORE ZONES
ALONG THE CHESAPEAKE BAY.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.
TONIGHT...PRIMARILY VFR TO MVFR. RESTRICTIONS DUE TO LOW
STRATUS/PATCHY FOG ARE POSSIBLE TONIGHT. THIS IS LOWER
CONFIDENCE DUE TO SOME DRIER AIR MOVING IN, WHICH CAN LIMIT THE
EXACT EXTENT OF ANY RESTRICTIONS. NORTHEAST WINDS AROUND 5 KT
WITH PERIODS OF LIGHT AND VARIABLE. MODERATE CONFIDENCE OVERALL
WITH LOW CONFIDENCE REGARDING THE EXTENT OF ANY STRATUS OR PATCHY
FOG.
SUNDAY...VFR. EAST WINDS 5 TO 10 KT. HIGH CONFIDENCE.
OUTLOOK...
SUNDAY NIGHT THROUGH THURSDAY...VFR. NO SIGNIFICANT WEATHER.
MARINE
SUB-SCA CONDITIONS EXPECTED THROUGH SUNDAY. EAST/NORTHEAST WINDS
AROUND 10-15 KT AND SEAS 2 TO 4 FEET.
SOME SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING WHICH
COULD RESULT IN FREQUENT LIGHTNING AND A BRIEF INCREASE IN
WINDS AS WELL AS VISIBILITY RESTRICTIONS.
OUTLOOK...
SUNDAY NIGHT THROUGH WEDNESDAY...NO MARINE HEADLINES EXPECTED.
FAIR WEATHER.
RIP CURRENTS...
FOR SUNDAY, ONSHORE FLOW STRENGTHENS A BIT WITH AN EAST TO NORTHEAST
WIND AROUND 15 MPH. HOWEVER, BREAKING WAVE HEIGHTS REMAIN LOW
(1 TO 3 FEET) AND THE DOMINANT WAVE PERIOD SHOULD ONLY BE AROUND
7 SECONDS. THIS WILL RESULT IN A LOW RISK FOR RIP CURRENTS AT
ALL BEACHES.
FOR MONDAY, ONSHORE FLOW CONTINUES WITH AN EAST TO SOUTHEAST
WIND AROUND 10-15 MPH. BREAKING WAVE HEIGHTS OF 1 TO 3 FEET
REMAIN AND THE DOMINANT WAVE PERIOD SHOULD BE AROUND 7 SECONDS.
THERE IS ALSO AN INCREASING SOUTHEASTERLY SWELL ALONG WITH THE
NEW MOON ON TUESDAY. THIS WILL ALL RESULT IN A MODERATE RISK FOR
RIP CURRENTS AT ALL BEACHES.
