AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 816 AM EDT TUE AUG 13 2013 .SYNOPSIS... A COLD FRONT WILL PASS THROUGH THE REGION TODAY, ACCOMPANIED BY SHOWERS AND THUNDERSTORMS. FAIR AND COOLER WEATHER WILL FOLLOW THE FRONT WITH SLOWLY MODERATING TEMPERATURES BY LATE WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 815 AM UPDATE...NEAR TERM GRIDS UPDATED TO REFLECT A MORE RAPID EWD MVMNT OF STEADIER PCPN. RAINFALL RATES ARND 1 INCH IN HEAVIER CORES WITH HEAVIEST RAINS NOW OVER THE CATSKILLS...WHERE A FLOOD ADVISORY HAS BEEN ISSUED. CDFNT STILL BACK TO THE WEST...SO SCT SHRA/ISOLATED TSRA STILL PSBL UNTIL FROPA. PREV BLO... 6 AM UPDATE...SFC COLD FRONT NOW ABOUT TO ENTER WESTERN NEW YORK WITH CONVECTION OVER WESTERN CWA BEGINNING TO WEAKEN AND BECOME MORE FRAGMENTED. WITH BOUNDARY STILL WEST OF AREA SHOWERS WILL PERSIST HERE UNTIL MID MORNING BUT THE HEAVIEST ACTIVITY IS ALREADY SHIFTING EAST. CONVECTION OVER NE PA ARRIVED A LITTLE EARLIER THAN EXPECTED AND MADE POP ADJUSTMENTS TO REFLECT THIS. HEAVIEST RAINFALL REMAINS SOUTH OF FA IN AREA OF BETTER JET DYNAMICS, ISENTROPIC LIFT AND HIGHER PWAT AIRMASS. PREVIOUS DISC... AT 4 AM...SFC COLD WAS LOCATED JUST WEST OF TORONTO SOUTHWEST TO NEAR CLEVELAND. LOCAL RADARS SHOWED WIDESPREAD SHOWERS AND SCATTERED THUNDERSTORMS OVER THE LAKE PLAIN BACK THROUGH WESTERN NEW YORK. MODEL CONSENSUS HAS SLOWED THE PROGRESSION OF FRONT THROUGH CWA BY 2-4 HOURS DUE TO SEVERAL WAVES ALONG BOUNDARY. ONE SFC REFECTION WILL MOVE ACROSS CENTRAL NY WITH THE SOUTHERN WAVE TRACKING THROUGH SOUTHERN PA ACROSS CNTRL NJ TO LONG ISLAND. WILL CARRY CATEGORICAL POPS ACROSS NRN CWA EARLY THIS MORNING THEN SPREAD THIS ACROSS THE REST OF FA SHORTLY AFTER SUNRISE AS BOUNDARY APPROACHES AND MOISTURE FROM SOUTHERN WAVE SPREADS ACTIVITY ACROSS FAR SE FA. A STRENGTHENING UPPER LEVEL JET EARLY THIS MORNING WILL PRODUCE FAIRLY STRONG UPPER LEVEL DIVERGENCE JUST SOUTH OF AREA. A SWATH OF VERY HEAVY RAIN IS EXPECTED OVER SE PA EAST ACROSS CNTRL NJ TO LONG ISLAND AND IS EXPECTED TO REMAIN SOUTH OF THE WYOMING VALLEY AND NORTHERN POCONOS. IF ACTIVITY SPREADS FARTHER NORTH THAN EXPECTED, LATER SHIFTS MAY NEED TO ISSUE A FLASH FLOOD WATCH. EVEN SO WITH PWATS 1.5-1.8 INCHES ANY THUNDERSTORM WILL BE ACCOMPANIED BY VERY HEAVY DOWNPOURS AND BE CAPABLE OF PRODUCING POOR DRAINAGE FLOODING. ISSUED HWO TO HIGHLIGHT THIS HAZARD. A GENERAL RAINFALL OF HALF INCH TO AROUND ONE INCH IS LIKELY ACROSS THE REGION. BY MID AFTERNOON MUCH OF THE ACTIVITY WILL BE EAST OF THE FA. SEVERE WEATHER POTENTIAL STILL LOOKS MINIMAL DUE TO LIMITED CAPE AS ACTIVITY IS ALREADY ONGOING WELL BEFORE SUNRISE AND MID LEVEL LAPSE RATES ARE NOT THAT STEEP. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/... A BROAD UPPER LEVEL TROF WILL REMAIN OVER THE NORTHEAST DURING THIS PERIOD AS SFC HIGH PRES DROPS FROM THE UPPER GREAT LAKES INTO THE OHIO VALLEY KEEPING A COOL W/NW FLOW OVER THE REGION. LATER TONIGHT T85 DROPS TO AROUND 5C WHICH IS COLD ENOUGH TO PRODUCE SOME LIGHT LAKE EFFECT RAIN SHOWERS E/SE OF LAKE ONTARIO. WILL CONTINUE TO CARRY SLIGHT CHC/CHC POPS FOR THIS ACTIVITY WITH HIGHEST POPS WEDNESDAY MORNING AS LOW LEVEL FLOW BACKS SLIGHTLY AND ALLOWS A BETTER FETCH DOWN LAKE ONTARIO. BY MIDDAY WEDNESDAY ACTIVITY SHOULD END DUE TO AIRMASS DRYING. FOR MOST OF THE AREA OVERNIGHT PERIODS WILL BE PARTLY CLOUDY TO MAINLY CLEAR WITH COOL SEASON TYPE STRATO CU FORMING DURING THE DAYLIGHT HOURS RESULTING IN PARTLY TO MOSTLY CLOUDY SKIES. MAXES ON WED WILL RANGE FROM THE MID 60S TO LOWERS 70S WITH READINGS MODIFYING INTO THE LOWER/MIDDLE 70S ON THURSDAY. && .LONG TERM /FRIDAY THROUGH MONDAY/... 1 PM MON UPDATE... ON THE LARGE-SCALE...THE TWO MAIN FIXTURES THIS PD WILL BE A STRENGTHENING WRN ATLANTIC UPR RIDGE...AND A WRN CONUS UPR RIDGE AXIS. IN BETWEEN THE TWO...A WEAKNESS IN THE HGT FIELDS LOOKS TO EXIST...WITH A FLAT MEAN TROUGH AXIS IN PLACE FROM THE TN VLY SWD TO THE GULF STATES. THE PRIMARY INFLUENCING SYSTEM FOR NY/PA DURG THIS TIME FRAME SHOULD BE THE WRN ATLANTIC UPR RIDGE...WITH A STG "BERMUDA HIGH" TYPE SFC ANTICYCLONE...EXTENDING FROM THE WRN ATLANTIC...BACK OVER THE ERN STATES. THIS SYNOPTIC PATN SEEMS FAVORABLE FOR A PROLONGED STRETCH OF DRY WX ACRS OUR FA...ALG WITH SLOWLY WARMING TEMPS OVER TIME. THE LATEST GFS/EC/WPC PROGS AGREE THAT THIS WILL INDEED BE THE CASE. FROM THIS EARLY VANTAGE PT...IT APPEARS THAT THE FIRST REAL CHC FOR ANY PCPN WON'T BE TIL SOMETIME EARLY NEXT WEEK (MON OR PERHAPS BEYOND)...WHEN SOME GULF MOISTURE ATTEMPTS TO PUSH NWD. EVEN AT THAT...WE'RE ONLY ADVERTISING SCHC-CHC POPS ATTM FROM LATE SUN NGT INTO NEXT MON. TEMPS WILL BE FAIRLY SEASONABLE MUCH OF THE PD...WITH HIGHS STARTING OFF IN THE 70S THU...GRADUALLY MODERATING INTO THE LWR- MIDDLE 80S BY LTR IN THE WEEKEND/NEXT WEEK. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... 06Z UPDATE... AN AREA OF RAIN WITH EMBEDDED THUNDER CONTINUES TO MARCH ACROSS WESTERN NY AHEAD OF A COLD FRONT. EXPECT RAIN TO ARRIVE AT ALL TERMINALS BETWEEN 07Z AND 11Z. BASED ON OBS TO OUR WEST AND A MOISTURE LADEN ATMOSPHERE...IFR VSBYS ARE LIKELY FOR A 3 TO 4 HOUR PERIOD THIS MORNING DUE TO MODERATE/HEAVY RAIN. INCLUDED A TEMPO GROUP TO COVER THIS ROUGHLY IN THE 08Z TO 14Z TIME FRAME. FOR NOW I LEFT OUT ANY MENTION OF THUNDER IN THE TAFS WITH WEAKER LAPSE RATES ACROSS OUR AREA. WITH THE 09Z UPDATE I MAY HAVE TO ADD IN THUNDER CHANCES IF LIGHTNING STRIKES REMAIN IMPRESSIVE. ONCE THE INITIAL AREA OF RAIN MOVES TO THE EAST...NOTHING WIDESPREAD ENOUGH IS EXPECTED TO OCCUR TO INCLUDE IN THE TAFS. MVFR CIGS ARE POSSIBLE FOR A FEW HOURS BEFORE VFR RETURNS LATER THIS AFTERNOON. SOUTHWEST WINDS WILL SHIFT AROUND TO THE NW AFTER FRONT PASSES THIS AFTERNOON. GENERALLY WINDS WILL BE 5 TO 10 KTS BUT WE MAY SEE A FEW GUSTS ABOVE 10 KTS BEHIND THE FRONT THIS AFTERNOON. OUTLOOK... TUE NGT...A PD OF MVFR CIGS PSBL...SPCLY ACRS CNY. WED THRU SAT...MAINLY VFR.
