AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW YORK NY 757 PM EDT SAT JUL 7 2012 .SYNOPSIS... A COLD FRONT PASSES THROUGH TONIGHT AND STALLS TO THE SOUTH THROUGH THE WEEK. WEAK HIGH PRESSURE PUSHES IN FROM THE WEST...WHILE MULTIPLE WEAK WAVES ARE EXPECTED TO RIDE ALONG THE STALLED FRONT. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... HAVE ALLOWED SVR TSTM WATCH TO EXPIRE AT 7PM WITH MAIN CLUSTER OF STORMS PASSING JUST TO OUR SOUTH. WDLY SCT CELLS ACROSS CT AND SOUTH CENTRAL NY STATE WILL TRACK SE THIS EVE...HOWEVER INSTABILITY IS WANING WITH THE LOSS OF HEATING. ATMOSPHERE NEVER REALLY RECOVERED FROM THE FIRST BATCH OF SHOWERS/TSTMS THAT MOVED THROUGH LATE THIS MORNING/EARLY AFTN AND BEST INSTABILITY/THETA E ADVECTION REMAINED S OF THE CWA. HAVE KEPT LOW CHC SHRA/TSRA WITH GUSTY WINDS FOR A FEW MORE HOURS THIS EVENING...BUT THREAT IS DECREASING. ADJUSTMENTS TO HOURLY T/TD/SKY BASED ON LATEST OBS/TRENDS. A POST FRONTAL TROUGH COULD KEEP SOME LINGERING SHOWERS/TSTORMS IN THROUGH THE EARLY MORNING HOURS. TEMPS WILL REMAIN ABOVE NORMAL FOR ONE MORE NIGHT WITH THE 925MB SLOW TO DIMINISH BEHIND THE FRONT. GUIDANCE IN GENERAL AGREEMENT FOR TEMPS TONIGHT...SO WENT WITH A MET/MAV BLEND. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... THE COLD FRONT PUSHES THROUGH THE CWA DURING THE NIGHT...BUT THEN STALLS JUST TO THE SOUTH...LINGERING BACK INTO THE MID ATLANTIC STATES. THIS PROVIDES SOME GOOD NEWS TO THE NORTHEAST AS NORTHERLY TO NORTHWESTERLY FLOW BEHIND THE FRONT ENABLES COOLER TEMPS TO FINALLY BEING MOVING IN...WITH 850MB SLOWLY DIMINISHING DURING THE DAY SUNDAY...DROPPING TO THE LOWER TEENS. THERE REMAINS THE POTENTIAL FOR SOME LINGERING SHOWERS AND THUNDERSTORMS EARLY TOMORROW MORNING...BUT OTHERWISE...EXPECTING A FAIRLY DRY IN STORE WITH ANY SHOWER/TSTORM DEVELOPMENT EXPECTING TO STAY ALONG THE FRONT TO THE SOUTH. SKIES WILL BE SLOW TO CLEAR AS WELL IN THE MORNING...BUT WITH THE DRIER AIR MAKING ITS WAY IN...SHOULD SEE PARTLY CLOUD SKIES IN THE AFTERNOON. THIS WILL ENABLE TEMPS TO WARM INTO THE 80S AND 90S...BUT WITH DEW PTS CONTINUALLY DROPPING...NOT EXPECTING MUCH WITH HEAT INDICES...AND ESP NOT EXPECTING ANY FURTHER HEAT RELATED ADVISORIES/WARNINGS. THE COLD FRONT REMAINS TO THE SOUTH TOMORROW NIGHT...WHILE HIGH PRESSURE BUILDS IN FROM THE WEST. DRY CONDITIONS CONTINUE...WITH ONLY THE SLIGHT CHC OF PRECIP IN THE FAR SOUTHERN PORTIONS OF THE OCEAN WATERS AND NOTHING ON LAND. MOST AREAS SHOULD SEE PARTLY CLOUD SKIES UNDER UPPER LEVEL SUBSIDENCE...WITH SOUTHERN AREAS POSSIBLY SEEING MOSTLY CLOUDY CONDITIONS AS CLOUD DEBRIS FROM THE STORMS OVER THE MID ATLANTIC STATES EDGE IN. && .LONG TERM /MONDAY THROUGH SATURDAY/... GOOD AGREEMENT IN THE LONG TERM THROUGH WEDNESDAY NIGHT...THEN MODELS DIVERGE. UPPER LEVEL TROUGH SETTLES AND AMPLIFIES SLIGHTLY OVER THE NORTHEAST AND MID-ATLANTIC WHILE COLD FRONT REMAINS STALLED TO THE SOUTH OF THE CWA FOR MUCH OF THE LONG TERM PERIOD. WEAK AREAS OF LOW PRESSURE WILL RIDE ALONG THIS BOUNDARY REMAINING OFFSHORE THROUGH WEDNESDAY NIGHT. THE MAIN DIFFERENCE BETWEEN THE 00Z ECMWF AND THE 12Z GFS IS THAT THE GFS BRINGS A SLIGHTLY STINGER LOW PRESSURE CLOSER TO THE COAST WEDNESDAY NIGHT INTO THURSDAY. THIS IS MUCH SLOWER THAN THE MORE PROGRESSIVE ECMWF. THIS SURFACE LOW IS IN RESPONSE TO A CUT OFF LOW THAT BEGINS TO DEVELOP ALONG THE SOUTHERN EDGE OF THE UPPER TROUGH OVER THE OHIO VALLEY IN THE GFS WHILE THE ECMWF LIFTS THE UPPER TROUGH OUT OF THE AREA. DUE TO THE UNCERTAINTY...KEPT SLIGHT CHANCE POPS IN THE FORECAST FOR WEDNESDAY NIGHT THROUGH THURSDAY NIGHT. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... A COLD FRONT MOVES SLOWLY ACROSS THE AREA OVERNIGHT AND SETTLES JUST TO THE SOUTH SUNDAY. GENERALLY VFR CONDITIONS EXPECTED AS ANY LEFTOVER ISOLATED CONVECTION DIMINISHES IN COVERAGE TONIGHT. VFR SUNDAY WITH SC AND AC CLOUDS...MAINLY IN THE MORNING. CLEARING IN THE AFTERNOON. WINDS WILL BE LIGHT THIS EVENING...THEN TURN TOWARD THE NORTH/NORTHWEST LATER THIS EVENING AND OVERNIGHT. SPEEDS REMAIN LIGHT. ON SUNDAY...LIGHT NORTH WINDS IN THE MORNING INCREASE TO 10 TO 15 KTS DURING THE AFTERNOON AS THEY TURN BACK TOWARD THE NORTHWEST. A GUST OR TWO IS POSSIBLE DURING THE AFTERNOON...BUT ANY GUSTS SHOULD REMAIN BELOW 20 KTS. OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY... .SUNDAY NIGHT THROUGH THURSDAY...VFR. && .MARINE... WDLY SCT SHOWERS/TSTMS THIS EVE...STRONGEST OVER THE WESTERN OCEAN WATERS NEXT FEW HOURS. CONDITIONS ARE EXPECTED TO REMAIN BELOW SCA CRITERIA THROUGH THE END OF THE WEEKEND. QUIET CONDITIONS MONDAY THROUGH WEDNESDAY MORNING WITH HIGH PRESSURE IN CONTROL. WINDS WILL REMAIN BELOW SCA CRITERIA...THOUGH WAVES BUILD TO 5 FT WEDNESDAY NIGHT WITH AS AN ONSHORE FLOW DEVELOPS. && .HYDROLOGY... LESS THAN A QUARTER OF AN INCH OF RAINFALL IN LINGERING SHOWERS/TSTMS THIS EVE. NO HYDROLOGY ISSUES ARE EXPECTED. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...NONE. NJ...NONE. MARINE...NONE. &&
