AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
155 PM EDT THU APR 2 2015
.SYNOPSIS...
HIGH PRES OVER THE EASTERN SEABOARD DRIFTS SE TODAY. A SLOW
MOVING FRONTAL SYSTEM IMPACTS THE AREA FRI INTO SAT. A COLD FRONT
PASSES ON SUN...FOLLOWED BY HIGH PRES FOR MON. ANOTHER FRONTAL
SYSTEM MAY IMPACT THE REGION TUE AND WED.
&&
.NEAR TERM /THROUGH TONIGHT/...
FOR THIS AFTERNOON...TEMPS WARMING QUICKLY AND WINDS GUSTING A BIT
HIGHER THAN ANTICIPATED AWAY FROM THE WATER. HAVE BUMPED MAX TEMPS
UP SEVERAL DEGREES ESPECIALLY ACROSS NE NJ...THE LOWER HUDSON
VALLEY AND INTERIOR CT AS A RESULT. WINDS WILL GUST 30-35 MPH EVEN
OUTSIDE OF THE WIND ADVISORY AREA THIS AFTERNOON. WITHIN THE
ADVISORY...WINDS WILL INCREASE MARKEDLY DURING THE MID TO LATE
AFTERNOON HOURS.
OTHERWISE...WATER VAPOR SHOWED DEVELOPING CONVECTION OVER KS AND
MO INVOF DEVELOPING LOW PRES. THE REMNANTS OF THESE WILL MAKE IT
TO THE CWA BY FRI. IN THE MEANTIME...HIGH PRES CENTERED OVER CAPE
HATTERAS WILL DRIFT OUT INTO THE ATLC...RESULTING IN INCREASING
RETURN FLOW ACROSS THE CWA. THE PRES GRAD STRENGTHENS AS LOW PRES
DEEPENS INTO THE 980S OVER ONTARIO TODAY. AS A RESULT...STRONG SLY
FLOW DEVELOPS ACROSS THE CWA. SST/S IN THE UPR 30S WILL ENHANCE
THE FLOW ALONG THE S COAST OF LI...WITH A LOCALIZED JET INTO WRN
PORTIONS OF LI. THE MODELS HAVE BEEN CONSISTENT WITH THIS FEATURE
FOR A FEW DAYS NOW...WITH THE MAV CONTINUING TO SUGGEST SUSTAINED
FLOW AOA 28KT AT KJFK. HAVE ISSUED A WIND ADVY FOR THESE JET PRONE
AREAS: BROOKLYN...SRN QUEENS AND SRN NASSAU...FOR SUSTAINED WINDS
AROUND 30 MPH. EXPECT GUSTS TO REMAIN BLW CRITERIA ATTM...WITH
TIME HEIGHTS SUGGESTING ONLY 40KT AT 2K FT. WINDS ALOFT STRENGTHEN
TNGT...BUT A STRENGTHENING INVERSION ALONG WITH INCREASING PCPN
CHCS SHOULD LIMIT THE WIND THREAT. OUTSIDE OF THE WIND...SOME MID
AND HIGH CLOUDS ADVECTING IN FROM THE NW GIVE WAY TO AN ADVANCING
MID CLOUD SHIED LATE THIS AFTN INTO TNGT AS STRONG MOISTURE
TRANSPORT FROM THE SW COMMENCES. THE RESULTANT SURGE OF THETA-E
SHOULD LEAD TO THE DEVELOPMENT OF SHWRS OVER THE AREA. THE WELL
MIXED LLVLS WILL KEEP TEMPS MILD FOR THE OVERNIGHT.
&&
.SHORT TERM /FRIDAY/...
THE APPROACHING UPR JET IS PROGGED TO ALLOW FOR WIDESPREAD RAIN TO
DEVELOP THRU THE DAY. THE LATEST MESOSCALE DATA FROM THE NAM SHOWS
NO SBCAPE OVER THE CWA...KEEPING IT RELEGATED GENERALLY TO PA AND
POINTS SWWD. IN ADDITION...THERE IS LITTLE TO NO CONVECTIVE PCPN
PRODUCED IN THE MODEL...SUGGESTING A LACK OF EVEN ELEVATED CAPE.
AS A RESULT...WILL NOT FCST TSTMS FOR THIS PERIOD. WITH THE MODELS
IN GOOD AGREEMENT...A BLEND OF GUIDANCE WAS USED FOR TEMPS.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
LOW LEVEL JET KEEPS PERIODS OF RAIN/SHOWERS FOR FRIDAY NIGHT WITH
A THREAT OF A THUNDERSTORM. RELATIVELY HIGHER DEWPOINT AIR MOVING
OVER THE COLD WATERS PROBABLY PRODUCES PATCHY/AREAS OF FOG FRIDAY
AND FRIDAY NIGHT.
COLD FRONT SHOULD BE THROUGH MOST OF THE CWA BY 12Z SATURDAY...SO
OUTSIDE OF LOW CHANCES OF SHOWERS EARLY ON...DRY WEATHER WITH
CLOUDS DIMINISHING. HIGHS A LITTLE BELOW NORMAL WITH A GUSTY NW
WIND.
THE FLOW ALOFT SUNDAY THROUGH WEDNESDAY IS FORECAST TO BE
GENERALLY ZONAL. THIS WILL WEAKEN A COLD FRONT DROPPING DOWN FROM
THE NORTH ON SUNDAY. MODELS DISAGREE WHERE THIS FRONT EVENTUALLY
STALLS BEFORE LIFTING BACK NORTH. THIS HAS IMPLICATIONS ON PCPN
CHANCES AS WELL AS TEMPERATURES. BEST GUESS CONSIDERING A ZONAL
FLOW IS THAT SHOULD THE FRONT PASS COMPLETELY THROUGH THE CWA...IT
WILL STALL JUST OFFSHORE TO OUR SOUTH. ECMWF IS APPEARING TO TREND
THIS WAY...WHICH IS TOWARDS THE GFS AND GGEM. GIVEN THE
UNCERTAINTY...HAVE GONE WITH A PROLONGED PERIOD OF SLIGHT CHC TO
CHC POPS SUNDAY AFTN THROUGH WEDS. MUCH OF THE TIME SHOULD BE
DRY...BUT THE THREAT OF RAIN SHOULD REMAIN. MIGHT EVEN BE ABLE TO
EVENTUALLY REMOVE POPS FOR MONDAY. PCPN TYPE WILL BE RAIN...EXCEPT
LATE SUNDAY NIGHT INTO EARLY MONDAY MORNING NORTH OF THE CITY
WHERE A MIX OF RAIN AND SNOW WILL BE POSSIBLE.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
HIGH CONFIDENCE IN VFR THROUGH THIS EVENING. THE CONFIDENCE LOWERS
LATE TONIGHT AS A COLD FRONT APPROACHES. MVFR AND CHANCES OF RAIN
INCREASE OVERNIGHT. IFR WILL BE LIKELY BY FRIDAY MORNING AND THEN
SOME MARGINAL IMPROVEMENT TO MVFR AND POSSIBLY VFR IS EXPECTED BY
FRIDAY AFTERNOON...PARTICULARLY AWAY FROM THE COAST.
MAIN ISSUE THROUGH THE EVENING WILL BE WINDS. SOUTHERLY FLOW
PEAKS LATE THIS AFTERNOON THROUGH THIS EVENING AS LOW LEVEL JET
OF 50-60 KT AT 2KFT MOVES IN. EXPECT WINDS SUSTAINED NEAR 20-30
KT WITH GUSTS NEAR 35 KT LATER THIS AFTERNOON AND THIS EVENING.
PEAK GUSTS COULD REACH 40 KT NEAR KJFK.
