Area forecast discussion, Jul 20, 2:07 PM EDT, 2 hours 9 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
207 PM EDT SAT JUL 20 2013
.SYNOPSIS...
A WEAK TROUGH OF LOW PRESSURE WILL REMAIN NEAR THE COAST THROUGH EVENING.
A COLD FRONT WILL MOVE SOUTHEAST ACROSS THE AREA TONIGHT...PASSING JUST
SOUTH OF THE LOCAL AREA BEFORE STALLING ON SUNDAY. A WAVE OF LOW PRESSURE
WILL MOVE NORTHEAST ALONG THIS FRONT TUESDAY INTO WEDNESDAY. THIS FRONT
WILL REMAIN NEARLY STATIONARY SOUTH OF THE REGION THROUGH THE END OF
THE WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A HEAT ADVISORY REMAINS IN EFFECT FOR MOST OF THE AREA AND IS ON
TRACK AS HEAT INDEX VALUES REACHED 100 AT 1 PM. VALUES WERE RISING
STEADILY INTO THE UPPER 90S ACROSS THE METRO AREA.
SCATTERED TSTMS ARE DEVELOPING ACROSS THE HUDSON VALLEY. WITH THE
COASTAL TROUGH SERVING AS THE LIFTING TRIGGER...ADEQUATE MOISTURE
AND INCREASING LOW LVL INSTABILITY...AREAL COVERAGE AND INTENSITY
IS FORECAST TO INCREASE.
THE BEST DYNAMICS ARE ACROSS THE NORTHERN PORTION OF OUR LOCAL AREA.
THE SPC ISSUED A SEVERE TSTM WATCH FOR THIS AREA UNTIL 9 PM THIS
EVENING.
THERE IS A HIGH RISK OF RIP CURRENTS AT THE ATLANTIC BEACHES OF
NASSAU AND SUFFOLK COUNTIES WITH A MODERATE RISK AT THE NEW YORK
CITY BEACHES THROUGH EARLY THIS EVENING.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
THE CONVECTION WILL STILL BE AROUND FOR THIS EVENING AS THE
FRONTAL BOUNDARY SITS ACROSS THE REGION. EXPECTING THE FRONTAL
BOUNDARY TO GRADUALLY SINK FARTHER SOUTH OF THE AREA THROUGH THE
NIGHT AS FLOW ALOFT BECOMES MORE ZONAL...WITH A COINCIDENT
DECREASE IN CONVECTIVE COVERAGE FROM NORTH TO SOUTH. A RELATIVELY
COOLER AIR MASS WILL START TO MOVE INTO NORTHERN SECTIONS OF THE
REGION BUT OVERALL LOWS WILL STILL RANGE FROM THE MID 60S TO MID
70S.
FOR SUNDAY AND MONDAY...THE COLD FRONT WILL BE SOUTH OF THE
REGION BUT WITH PERIODIC SHORTWAVES ALOFT RIDING ACROSS ALONG THE
ZONAL FLOW...THERE WILL BE A CHANCE OF SHOWERS AND THUNDERSTORMS.
MODELS ARE SHOWING CAPE BUILD UP ON SUNDAY AROUND 500-1000 J/KG ACROSS
THE INTERIOR WHICH WILL PROVIDE RELATIVELY HIGHER CHANCES OF
CONVECTION THERE WITH OTHERWISE SLIGHT CHANCES ELSEWHERE. THE NEXT
REMARKABLE CHANCE OF WIDESPREAD OF SHOWERS WILL BE MONDAY NIGHT
WHEN A STRONGER SHORTWAVE WILL BRING IN MORE SOUTHWEST FLOW ALOFT.
THIS WILL ACT TO MOVE THE FRONTAL BOUNDARY THAT IS SOUTH OF THE
AREA FARTHER NORTH...MAKING FOR A GREATER CHANCE ON TUESDAY OF
CONVECTION.
TEMPERATURES SUNDAY WILL BE COOLER THAN THE PREVIOUS DAY...WELL
INTO THE 80S TO NEAR 90 AND LOW TO MID 80S FOR MONDAY. DEW POINTS
WILL BE LOWER AS WELL...WITHIN THE MID AND UPPER 60S. THE
TEMPERATURES WILL FEEL LESS OPPRESSIVE AS A RESULT.
&&
.LONG TERM /TUESDAY THROUGH SATURDAY/...
A WEAK AREA LOW PRESSURE THEN APPROACHES ON TUESDAY ALONG WITH
SEVERAL WEAK SHORTWAVES WITHIN THE UPPER LEVEL TROUGH. GUIDANCE
HAS COME INTO BETTER AGREEMENT WITH THIS SCENARIO WHICH SETS THE
STAGE FOR HIGHER CHANCES OF SHOWERS AND STORMS TUESDAY INTO
TUESDAY EVENING. THE LOW THEN DRIFTS OFFSHORE AND SENDS A WEAK
COLD FRONT THROUGH THE REGION BY WEDNESDAY MORNING.
THE FRONT THEN BECOMES NEARLY STATIONARY JUST SOUTH OF LONG ISLAND
ON WEDNESDAY. THE 12Z GFS AND 12Z ECMWF KEEP THE BOUNDARY CLOSE
ENOUGH ALONG WITH CONTINUED UPPER LEVEL TROUGHING TO PROMOTE
DIURNALLY DRIVEN SHOWERS AND STORMS. HAVE CAPPED POPS AT 30
PERCENT. THIS GENERAL PATTERN WILL CONTINUE INTO THE END OF THE
WEEK. THE 12Z GFS ACTUALLY SHIFTS THE FRONT FURTHER SOUTH BY
FRIDAY AS A WEAK HIGH PRESSURE BUILDS IN WHILE THE 12Z ECMWF
BRINGS THE BOUNDARY AND A WEAK WAVE OF LOW PRESSURE OVER THE AREA.
MUCH OF THIS STEMS FROM THE AMPLIFICATION OF THE EASTERN US TROUGH
AT THE END OF THE WEEK WITH THE GFS MORE PROGRESSIVE AND ECMWF
MORE AMPLIFIED. WITH ALL OF THIS IN MIND...ADVERTISING SLIGHT
CHANCE/CHANCE POPS ON THURSDAY AND FRIDAY.
DAYTIME TEMPERATURES FROM MONDAY THROUGH FRIDAY WILL BE IN THE
LOWER TO MIDDLE 80S...COOLEST NEAR THE COAST.
&&
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
THE FIRST SIGNS OF THUNDERSTORMS ARE NOW SHOWING UP ACROSS THE
LOWER HUDSON VALLEY. A HIGHLY UNSTABLE AIR MASS TO THE WEST OF
THE TERMINALS SHOULD RESULT IN INCREASING ACTIVITY OVER THE NEXT
SEVERAL HOURS ALONG AND AHEAD OF A PRE-FRONTAL TROF APPROACHING
FROM THE NW.
BEST CHANCE FOR AN ORGANIZED LINE OF CONVECTION LOOKS TO BE IN
THE 19-22Z TIME FRAME FOR NYC...PLUS OR MINUS A COUPLE OF HOURS TO
THE EAST AND WEST.
WINDS THIS AFTERNOON WILL BE SW AT 10 TO 15 KT WITH GUSTS TO AROUND
20 KT...DECREASING AND SHIFTING TO THE W/NW AT LESS THAN 10 KT
THIS EVENING. COLD FRONTAL PASSAGE LOOKS TO BE IN THE 00Z TO 03Z
TIME FRAME.
SOME LIGHT MVFR FOG/HAZE POSSIBLE TOWARD DAYBREAK SUN OUTSIDE THE
NYC TERMINALS.
EXPECTING VFR CONDITIONS ON SUN WITH A LIGHT NE FLOW BECOMING
ONSHORE AT THE COAST AND LIGHT AND VARIABLE INLAND.
.OUTLOOK FOR 18Z SUNDAY THROUGH THURSDAY...
.SUNDAY AFT-MON...MAINLY VFR.
.TUE AND WED...MVFR OR LOWER CONDS POSSIBLE IN SHOWERS/TSTMS.
.THU...MAINLY VFR.
&&
.MARINE...
A SMALL CRAFT ADVISORY CONTINUES ON THE OCEAN WATERS...MAINLY FOR
SEAS. SEAS ATTM ARE 5 FT ONLY AT BUOY 44017 OUT EAST...BUT
PERSISTENT SW FLOW 15-20 KT TODAY...HIGHEST EAST...SHOULD BRING
SEAS UP ANOTHER FOOT...WITH THESE SEAS LASTING INTO TONIGHT. SCT
TO NUMEROUS SHOWERS/TSTMS ARE ALSO EXPECTED THIS AFTERNOON AND
EVENING AHEAD OF A COLD FRONT.
QUIET CONDS EXPECTED THEREAFTER THROUGH MID WEEK.
&&
.HYDROLOGY...
THERE IS POTENTIAL FOR 1/4 TO 1/3 OF AN INCH OF BASIN AVERAGE RAINFALL
IN CONVECTION AHEAD AND ALONG THE COLD FRONT PASSAGE THROUGH TONIGHT...WITH
LOCALLY HIGHER AMOUNTS POSSIBLE. IF THESE LOCALLY HIGHER AMOUNTS ARE
REALIZED...MINOR FLOODING OF MAINLY URBAN AND POOR DRAINAGE IS POSSIBLE.
NO WIDESPREAD SIGNIFICANT RAINFALL IS FORECAST THROUGH THE UPCOMING
WEEK.
