AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW YORK NY 1255 AM EDT WED JUN 3 2009 .SYNOPSIS... A STATIONARY FRONT WILL REMAIN SOUTH OF THE AREA OVERNIGHT AND INTO WEDNESDAY. LOW PRESSURE RIDES ALONG THE FRONT AND PASSES TO THE SOUTH WEDNESDAY AND WEDNESDAY NIGHT. HIGH PRESSURE THEN BUILDS TO THE NORTH THURSDAY AND FRIDAY. LOW PRESSURE MOVES ALONG THE FRONT AND TRACKS TO THE SOUTHEAST FRIDAY INTO SATURDAY. ANOTHER COLD FRONT MOVES ACROSS THE REGION LATE SATURDAY AND SUNDAY. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... QUICK UPDATE TO ACCOUNT FOR MCS TRACKING NE ALONG BAROCLINIC ZONE FORM SE PA. EXPECT THIS FEATURE TO WEAKEN AS IT TRACKS NE...WITH A CHANCE OF REMNANTS SHOWERS WITH JUST SLIGHT CHANCE SHOWERS AS IT ENTERS MORE STABLE AIRMASS OVER REGION. REACHING SW CORNER OF CWA AROUND 5AM AND POSSIBLY SKIRTING SOUTHERN ZONES THROUGH DAYBREAK HOURS. OTHERWISE FRONT HAS SUNK JUST SOUTH OF THE AREA...CONTINUING TO ABOUT OUTER BOUNDARY OF FORECAST WATERS. NOT A BIG PUSH TO THE FRONT AS IT BECOMES PARALLEL TO MID AND UPPER LEVEL STEERING FLOW. FOLLOWED A MOS BLEND AS THEY WERE QUITE SIMILAR ANYWAY. && .SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/... UNSETTLED THROUGH THE PERIOD. COMPARING OP RUNS OF GFS/NAM OVERALL FEATURES APPEAR QUITE SIMILAR THROUGH THE PERIOD. SOME OUTPUT DIFFERENCES NOTED REGARDING QPF...ESPECIALLY LATE WED NIGHT AND THU. OTHERWISE...MAINLY A DRY START TO THE DAY WEDNESDAY AS NEXT WAVE OF LOW PRESSURE APPROACHES AS IT RIDES ALONG THE STATIONARY FRONT. SOME LOWERING OF HEIGHTS WEDNESDAY AND WEDNESDAY NIGHT AS UPPER TROUGH REMAINS ENTRENCHED ACROSS SOUTHEAST CANADA AND NEW ENGLAND. ALL MODELS RUNS (UKMET/RGEM/SREF/GEFS/NAM/GFS) IN AGREEMENT IN MOVING LOW JUST SOUTH. CWA ON THE NORTH/STABLE SIDE OF THIS FRONT AND LOW...WHICH WAS NOT THE CASE YESTERDAY AND PRIOR RUNS. AS SUCH...SFC BASED INSTABILITY LACKING...WITH SOME INSTABILITY ALOFT LATE WEDNESDAY AND WEDNESDAY NIGHT. SEVERE THREAT MINIMAL...BUT FLOODING REMAINS A CONCERN WITH POTENTIAL FOR SIGNIFICANT RAINFALL AS BAROCLINIC ZONE STRETCHES FOR LOCAL CWA WESTWARD THROUGH OHIO VALLEY. OCCASIONAL SHOWERS EXPECTED WEDNESDAY NIGHT INTO THURSDAY. GFS HAS BACKED OFF ON HEAVIER RAINFALL WEDNESDAY NIGHT...BUT BRINGS IN ANOTHER ROUND OF SHOWERS THURSDAY. NAM/EC/GEFS MEAN ON THE OTHER HAND DRY MUCH OF THE REGION OUT THURSDAY MORNING AS THE HIGH SUPPRESSES QPF WELL SOUTH. FOR NOW...WILL CONTINUE THEME OF RAIN IN THE MORNING...THEN DRYING IN THE AFTERNOON FROM NORTH TO SOUTH AND IRON OUT DETAILS AS THURSDAY NEARS. WILL KEEP MENTION IN HWO...BUT GREATER THAN AN INCH NOT A SLAM DUNK AS SOME GFS ENS MEMBERS KEEP HEAVIEST RAINFALL AXIS SOUTH OF THE AREA IN AREA OF GREATER INSTABILITY. DRY THURSDAY NIGHT...THEN NEXT WAVE OF LOW PRESSURE RIDES ALONG FRONT AND MOVES OFF MID ATLC COAST FRIDAY. CHC POPS FOR NOW FRIDAY...WITH HIGHEST POPS COASTAL LOCALES. THIS WILL NEED TO BE MONITORED. AS FOR TEMPS...BELOW NORMAL READINGS EXPECTED IN CLOUDS AND SHOWERS. AREA REMAINS TO THE NORTH OF THE BOUNDARY THROUGH THE PERIOD...SO THESE CLOUDS/ONSHORE FLOW AND COOLER CANADIAN AIRMASS OVER THE NORTHEAST WILL KEEP READINGS SLIGHTLY BELOW CLIMO. AGAIN...MOS BLEND FOLLOWED. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... A PROGRESSIVE UPPER FLOW WILL EXIST ACROSS THE NORTHERN MID-LATITUDES DURING THE LONG TERM PERIOD. THE ECMWF/CANADIAN/UKMET SHOW STRONGER SOLUTIONS ALOFT WITH A SHORTWAVE MOVING NEAR THE US/CANADIAN BORDER AND GREAT LAKES THIS WEEKEND INTO EARLY NEXT WEEK. THEIR SOLUTIONS HAVE CHANGED MARKEDLY SINCE THIS TIME YESTERDAY...AND A MORE SUBDUED/DEPRESSED SOLUTION IS ANTICIPATED CONSIDERING THEIR CHANGE IN CONTINUITY AND THE EXPECTATION THAT STRONG SUBTROPICAL RIDGING EXISTING IN THE WESTERN GULF OF MEXICO/NORTHWEST GULF COAST COULD HELP LIMIT THIS SHORTWAVES AMPLITUDE. THERE IS ALSO CONSIDERABLE SPREAD IN THE ENSEMBLE GUIDANCE WITH THE LOW TRACK ACROSS THE GREAT LAKES REGION LATE IN THE PERIOD...SO FORECAST CONFIDENCE IS LOW. TREND OVER THE LAST 24 HOURS HAS BROUGHT THE LOW MOVING OFF THE CAROLINA COAST FRI NIGHT CLOSER TO THE COAST...SO CHC POPS MAINLY ALONG THE COAST CONTINUES. DRY WEATHER RETURNS ON SAT AS A COLD FRONT APPROACHES FROM THE NW. THIS FROPA HAS TRENDED A LITTLE SLOWER AND IS NOW EXPECTED LATE SAT NIGHT INTO SUN MORNING. BEST UPPER SUPPORT IS WELL NORTH OF THE AREA WITH LIMITED MOISTURE...SO SCHC POPS WITH ITS PASSAGE SEEMS REASONABLE...BUT IT COULD BE DRY. LOW PRES OVER THE CENTRAL PLAINS MOVES TOWARDS THE EASTERN GREAT LAKES SUN NIGHT WITH A WARM FRONT APPROACHING FROM THE SOUTH. CHC POPS SUN NIGHT THROUGH TUE...ALTHOUGH THIS IS MAINLY DUE TO DIFFERENCES OF THE LOW TRACK BETWEEN THE MODEL GUIDANCE. SOLNS ARE SPLIT WHETHER THIS FRONT PUSHES NORTH OF THE LOCAL AREA...SO TEMPS AND WEATHER COULD CHANGE DRAMATICALLY IN SUBSEQUENT FORECASTS. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... VFR THROUGH THE PERIOD. FRONTAL BOUNDARY REMAINING SOUTH OF THE TERMINALS TONIGHT INTO WEDNESDAY WILL BE THE FOCUS OF ANOTHER WAVE OF LOW PRESSURE MOVING TOWARD THE TERMINALS WEDNESDAY AFTERNOON. THE CURRENT TRACK OF THE LOW IS SOUTH OF THE TERMINALS. RAIN WILL BECOME MORE LIKELY TOWARD THE END OF THE FORECAST PERIOD...20Z TO 00Z. THE BEST CHANCE OF THUNDER WILL BE ACROSS THE METRO NYC TERMINALS. UNCERTAINTY WITH THE WIND DIRECTIONS WEDNESDAY...WITH ANOTHER TROUGH PUSHING IN FROM THE NORTH...AND THE LOW TO THE SOUTH...AND SEA BREEZES MAY DEVELOP AFTER 17Z. OUTLOOK FOR 00Z THURSDAY THROUGH SUNDAY... WED NIGHT: MVFR CEILINGS AND VISIBILITIES IN SHOWERS AND POSSIBLY THUNDERSTORMS. THU: IMPROVING CONDITIONS TO VFR WITH SHOWERS ENDING. FRI: MVFR WITH SCATTERED SHOWERS. SAT: VFR. SUN: MVFR WITH SCATTERED SHOWERS. && .MARINE... SEAS A LITTLE LOWER THAN FORECAST...AND ALSO ADJUSTED WINDS FOR MOVEMENT OF THE COLD FRONT MOVING THROUGH THE WATERS OVERNIGHT. THE FRONT WILL STALL SOUTH OF THE AREA WATERS AND REMAIN STALLED OVER THE WATERS AS A SERIES OF LOW PRESSURE WAVES TRAVEL ALONG THE FRONT. A WEAK PRESSURE GRADIENT WILL KEEP WINDS AND SEAS BELOW SCA CONDITIONS. PERSISTENT EASTERLY FETCH AND TIGHTENING GRADIENT COULD BUILD SEAS TO SCA LEVELS ON THE OCEAN FRI NIGHT INTO SAT MORNING...BUT HAVE KEPT THEM JUST BELOW FOR NOW. CONDITIONS EXPECTED TO REMAIN BELOW SCA LATER SAT AND SUN. && .HYDROLOGY... NEXT SIGNIFICANT PRECIP EVENT EXPECTED WED AFTERNOON INTO THURSDAY MORNING.
