NWS New York, NY wrote its last area forecast discussion before the first event at Aug 6, 5:26 AM EST, 34 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE UPTON NY 626 AM EDT WED AUG 6 2008 .SYNOPSIS... AN AREA OF LOW PRESSURE WILL MOVE ACROSS THE TRI-STATE AREA TODAY...WHICH WILL RESULT IN SHOWERS AND THUNDERSTORMS. WEAK HIGH PRESSURE WILL BUILD IN FROM THE WEST TONIGHT...THEN SLIDE OFFSHORE ON THURSDAY. AN UPPER LEVEL LOW WILL KEEP CONDITIONS UNSETTLED THROUGH THE WEEKEND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... UPDATED ALL THE GRIDS EARLY THIS MORNING TO SPEED UP THE TIMING OF PRECIPITATION MOVING THROUGH THE CWA. A LINE OF SHOWERS AND THUNDERSTORMS MOVING ACROSS PARTS OF THE WESTERN CWA WILL CONTINUE TO PUSH EASTWARD AND SHOULD BE CLEAR OF THE AREA AROUND 17Z OR SO. ALL THIS IN ASSOCIATION WITH AN AREA OF LOW PRESSURE SYSTEM MOVING OUT OF CANADA AND ACROSS THE REGION. THE SHOWERS WILL PUSH ACROSS THE AREA THIS MORNING...BRINGING A PERIOD OF MODERATE TO LOCALLY HEAVY RAINFALL. WHILE THIS LINE HAS HELD TOGETHER MUCH OF THE NIGHT...IT HAS WEAKENED A BIT. REGARDLESS...WE ARE LOOKING AT ANYWHERE FROM A QUARTER TO A HALF INCH OF RAINFALL WITH THIS LINE. SOME OF THE RAIN MAY BE LOCALLY HEAVY. ONCE THESE SHOWERS PUSH OFF TO THE EAST...DRIER WEATHER IS EXPECTED..WITH ONLY A FEW ISOLATED AFTERNOON SHOWERS EXPECTED. FOLLOWED A GUIDANCE BLEND FOR TEMPERATURES. && .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/... WEAK HIGH PRESSURE BUILDS IN BEHIND THE AREA OF LOW PRESSURE TONIGHT...BRINGING DRIER WEATHER FOR WEDNESDAY NIGHT AND THURSDAY MORNING. AN UPPER LEVEL LOW WILL BUILD INTO THE AREA WHICH WILL PROVIDE A CHANCE OF SHOWERS AND THUNDERSTORMS THURSDAY AFTERNOON. A GREATER CHANCE OF SHOWERS AND STORMS WILL COME FRIDAY AFTERNOON. IT APPEARS AT THIS TIME THAT THURSDAY NIGHT AND FRIDAY MORNING COULD BE DRY AS WE ARE IN BETWEEN PULSES OF ENERGY ROTATING AROUND THE UPPER LOW. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... ANOMALOUS UPPER AIR PATTERN TO CONTINUE WITH NEGATIVE HEIGHT ANOMALIES THROUGH THE UPCOMING WEEKEND AND INTO EARLY NEXT WEEK. THIS SHOULD MEAN TEMPERATURES SLIGHTLY BELOW NORMAL THROUGH THE PERIOD. GLOBAL MODELS ARE HAVING A DIFFICULT TIME WITH THE HANDLING OF THE EASTERN NORTH AMERICAN TROF. IN PARTICULAR...THE 00Z ECMWF KICKS OUT THE INITIAL SHORT WAVE TROF OVER THE NORTHEAST ON DAY 3(FRI)...THEN DROPS A RATHER ROBUST UPPER LOW SE ACROSS JAMES BAY AND INTO EASTERN CANADA SAT THROUGH TUE. THIS ALLOWS FOR HEIGHT RISES ACROSS THE NE. TO THE CONTRARY...THE 12Z CANADIAN AND GFS KEEP THE INITIAL UPPER LOW/TROF OVER THE GREAT LAKES/NORTHEAST STATES AS THE PRIMARY FEATURE AND DO NOT LIFT IT OUT UNTIL EARLY NEXT WEEK. THIS RESULTS IN SIGNIFICANT DIFFERENCES WITH THE SURFACE FEATURES AND CREATES A LOW CONFIDENCE FORECAST. HOWEVER...THE ANOMALOUS PATTERN OF LATE WOULD SEEM TO BETTER SUPPORT THE TROUGHING AS SUPPORTED BY THE 12Z GFS...CANADIAN GLOBAL...AND UKMET. THE 12Z GFS HAS TRENDED WEAKER WITH THE UPPER TROUGH OVER THE NE....SO PERHAPS A SOLUTION SOMEWHERE IN BETWEEN THE 12Z GFS AND 00Z ECMWF IS THE BEST WAY TO HANDLE THE CURRENT EXTENDED FORECAST. GENERALLY...LOOKING FOR CONDITIONS TO DRY OUT FOLLOWING A COLD FRONTAL PASSAGE FRI NIGHT INTO SAT MORNING. THE SLOW EASTWARD MOVEMENT OF THE UPPER TROUGH ACROSS THE NE AND WEAK TROUGHING AT THE SFC THIS WEEKEND WILL MEAN A LOW PROBABILITY OF CONVECTION. && .AVIATION /10Z WEDNESDAY THROUGH SUNDAY/... LIGHT TO OCCASIONALLY MODERATE SHOWERS RESULTING IN MVFR CONDS ACROSS LI AND SOUTHERN CT. NYC TERMINALS HAVE RETURNED TO VFR. WITH A MORE SOLID AREA OF PRECIP APPROACHING...WILL UPDATE NYC TAF SITES TO START PRECIP SOONER THAN IN CURRENT FCST. EXPECT A 2-3 HOUR PERIOD OF IFR WITH VFR RETURNING 11-12Z. IFR CONDS GRADUALLY MOVE EAST INTO THE AFTERNOON. ISOLD/SCT SHRA POSSIBLE THIS AFTERNOON WITH LOCAL IFR MAINLY DUE TO LOW CIGS. OUTLOOK FOR 06Z THURSDAY THROUGH SUNDAY...HI PRES WILL ADVECT E RESULTING IN A DRY NW FLOW THROUGH EARLY THU. AS AN UPPER LEVEL LOW PRES SYS DEEPENS AND SPINS SE ACROSS THE EASTERN GREAT LAKES...SCT SHOWERS AND TSTMS WILL BE POSSIBLE DURING THE AFTERNOON AND EVENING DAILY...THU...FRI. HIGH PRESSURE RETURNS FOR VFR CONDITIONS SATURDAY AND SUNDAY. && .MARINE... WINDS/SEAS REMAIN BELOW SCA THROUGH THE PERIOD. EMBEDDED THUNDERSTORMS IN AN AREA OF PRECIP THIS MORNING MAY PRODUCE LOCALLY HIGHER SEAS THROUGH ABOUT 18Z. NO OTHER IMPACTS TO MARINE INTERESTS EXPECTED. && .HYDROLOGY... GENERALLY EXPECT FROM A QUARTER TO THREE QUARTERS OF AN INCH OF RAINFALL THROUGH WEDNESDAY WITH ISOLATED LOCALLY HIGHER AMOUNTS. DO NOT EXPECT ANY FLOODING AT THIS TIME. WITH CONVECTION EXPECTED TO BE SCATTERED AND DIURNAL IN NATURE WITH THIS WEEKENDS LOW...DO NOT ANTICIPATE ANY HYDROLOGIC ISSUES AT THIS TIME. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...NONE. NJ...NONE. MARINE...NONE. && SYNOPSIS...BC NEAR TERM...BC SHORT TERM...BC LONG TERM...DW AVIATION...BS MARINE...BS HYDROLOGY...BC
