NWS Albany, NY wrote its last area forecast discussion before the first event at Aug 16, 6:43 AM EST, 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 743 AM EDT MON AUG 16 2010 .SYNOPSIS... A COLD FRONT IN THE EASTERN GREAT LAKES EARLY THIS MORNING WILL MOVE EAST TODAY REACHING CENTRAL NEW YORK AROUND MID DAY...AND THEN PUSHING THROUGH EASTERN NEW YORK AND ADJACENT WESTERN NEW ENGLAND EARLY THIS EVENING. SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG AND AHEAD OF THE COLD FRONT...AND SOME OF THE THUNDERSTORMS MAY PRODUCE DAMAGING WINDS...HEAVY RAIN AND HAIL. HIGH PRESSURE WILL THEN BUILD INTO OUR REGION LATER TONIGHT AND LAST THROUGH WEDNESDAY MORNING GIVING US DRY AND SEASONABLE CONDITIONS. && .NEAR TERM /THROUGH TONIGHT/... SEVERE THUNDERSTORM WATCH 618 HAS BEEN ISSUED WHICH IS IN EFFECT UNTIL 1 PM EDT FOR THE EASTERN NEW YORK COUNTIES FROM SCHOHARIE...ALBANY AND RENSSELAER NORTH. WHILE IT IS STILL UNCERTAIN AS TO THE AMOUNT OF CONVECTION TODAY ACROSS FA WHICH WILL MOSTLY LIKELY DEPEND ON TIMING OF COLD FRONT ALONG WITH AMOUNT OF HEATING...CONVECTION THAT HAS ALREADY FIRED AND PRODUCED SOME STRONG THUNDERSTORMS ACROSS WESTERN AND CENTRAL NEW YORK WILL MOVE EAST ACROSS PORTIONS OF OUR AREA IN THE NEXT SEVERAL HOURS. HAVE THUS UPDATED FORECAST TO REFLECT WATCH AND MENTION THUNDERSTORMS MAY BE SEVERE IN THE WATCH AREA. HAVE ALSO INCREASED POPS TO LIKELY IN THE WATCH AREA. WILL CONTINUE TO KEEP ENHANCED WORDING IN THIS AFTERNOON AS MORE STRONG THUNDERSTORMS WILL CERTAINLY BE POSSIBLE. FOR THIS AFTERNOON...AFTER 1 PM...WILL HAVE LIKELY POPS FOR EASTERN THIRD OF FA...EAST OF THE HUDSON RIVER...AND CHANCE POPS WEST. H8 WIND FIELD NOT OVERLY IMPRESSIVE WITH CORE OF 30-35 KT MAX MOVING ACROSS NORTHERN THIRD OF FA EARLY TO MID AFTERNOON. H3 JET MUCH MORE IMPRESSIVE AT 90-100 KTS WITH AXIS SLICING THROUGH FA EARLY THIS AFTERNOON AS CORE IS ACROSS NORTHERN NEW ENGLAND PLACING BULK OF FA IN RIGHT ENTRANCE REGION OR RR QUAD. NCEP 0-3 KM HELICITY VALUES IN THE 100-180 M2/S2 RANGE...WHILE SB CAPE GENERALLY 600-1500 J/KG WITH HIGHEST VALUES EARLY TO MID AFTERNOON FROM HUDSON VALLEY TO POINTS SOUTH AND EAST. THE CAPE VALUES MAY BE SLIGHTLY LOWER HOWEVER IF DEWPOINTS REMAIN IN THE MID TO UPPER 60S AS OPPOSED TO LOWER 70S. IN ADDITION WET BULB ZERO HEIGHTS START TO LOWER SIGNIFICANTLY AROUND PEAK TIME FOR POTENTIAL CONVECTION EARLY TO MID AFTERNOON WITH HEIGHTS BETWEEN 8.5 AND 11 KFT EXPECTED. THUS THE POTENTIAL FOR SOME DAMAGING WINDS AND HAIL IS CLEARLY IN PLACE...BUT THE QUESTION REMAINS THE AMOUNT OF HEATING WHICH TAKES PLACE AHEAD OF THE FRONT WHICH WILL DEPEND ON WHEN THE STRATUS BURNS OFF. THINKING AT THIS TIME IS THAT MUCH OF THIS MORNING WILL REMAIN MOSTLY CLOUDY AND THAT IT WILL TAKE UNTIL 10 AM OR 11 AM TO START TO BURN OFF THE STRATUS. THIS WILL STILL GIVE MOST AREAS SEVERAL HOURS OF GOOD HEATING RESULTING IN HIGH TEMPS IN THE UPPER 70S TO MID 80S IN MOST AREAS. SOME LOCALLY HEAVY RAINFALL ALSO POSSIBLE AS PWATS RISE TO BETWEEN 1.5 AND 1.75 INCHES MAINLY ACROSS SOUTHEASTERN HALF OF FA. WHILE THUNDERSTORMS WILL TRACK FROM WEST SOUTHWEST TO EAST NORTHEAST AT 35 TO 45 MPH...SOME TRAINING OF CELLS IS POSSIBLE WHICH COULD RESULT IN SOME LOCALIZED POOR DRAINAGE FLOODING AND PONDING OF WATER ON THE ROADWAYS. THE SEVERE THREAT AND THE HEAVY RAINFALL THREAT IS HIGHLIGHTED IN THE HWO. ANY LINGERING CONVECTION SHOULD END EARLY THIS EVENING AND DO NOT EXPECT THUNDERSTORMS TO LINGER PAST 00Z. HAVE JUST A SLIGHT CHANCE TO CHANCE OF SHOWERS THIS EVENING BETWEEN 00Z AND 04Z MAINLY EAST OF THE HUDSON RIVER AND DRY WEST. HIGH PRESSURE WILL START TO BUILD INTO THE REGION LATER TONIGHT AND WITH DIMINISHING WINDS AND A CLEARING SKY EXPECT THE MAIN CONCERN LATER TONIGHT WILL BE FOG WHICH COULD BE LOCALLY DENSE ESPECIALLY IN AREAS WHICH RECEIVE SIGNIFICANT RAIN ON MONDAY. LOWS TONIGHT ARE EXPECTED TO RANGE FROM THE UPPER 40S NORTHWEST TO LOWER 60S SOUTHEAST. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY/... HIGH PRESSURE WILL CONTINUE TO BUILD INTO FA ON TUESDAY AND CREST ACROSS OUR REGION TUESDAY NIGHT BEFORE MOVING OFF THE NEW ENGLAND COAST ON WEDNESDAY. EXPECT THAT DRY WEATHER WILL HOLD FOR TUESDAY THROUGH THE FIRST PART OF WEDNESDAY...HOWEVER WEDNESDAY AFTERNOON LOOKS MORE UNCERTAIN ESPECIALLY FOR THE SOUTHEAST THIRD OF FA AS AN AREA OF LOW PRESSURE STARTS TO TRACK NORTHEAST FROM THE CAROLINAS. EXPECT MOSTLY SUNNY CONDITIONS FOR MUCH OF FA ON TUESDAY...EXCEPT PARTLY SUNNY ACROSS THE NORTHERN MOUNTAINS WHERE MORE INSTABILITY CUMULUS LIKELY. CLEAR TO PARTLY CLOUDY SKIES ON TUESDAY NIGHT AND THEN SOME INCREASING MID AND HIGH CLOUDS ON WEDNESDAY WHICH WILL LIKELY KEEP TEMPS ON WEDNESDAY A FEW DEGREES COOLER THAN TUESDAY. HAVE ALSO PLACED SLIGHT CHANCE TO LOW CHANCE POPS ACROSS FAR SOUTHEAST CORNER OF FA AS A FEW SHOWERS MAY MOVE INTO THIS AREAS IN ADVANCE OF LOW PRESSURE SYSTEM. EXPECT HIGH ON TUESDAY IN THE UPPER 70S TO UPPER 80S...LOWS TUESDAY NIGHT IN THE UPPER 40S TO AROUND 60...AND HIGHS ON WEDNESDAY IN THE MID 70S TO MID 80S. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... THE EXTENDED BEGINS WITH A STALLED OUT FRONTAL BOUNDARY SOUTH OF THE FCST AREA OVER THE MID ATLANTIC REGION...AND SOUTH OF THE SRN NEW ENGLAND COAST. THE 00Z GUIDANCE INCLUDING THE GFS...CANADIAN GGEM...AND EVEN THE ECMWF HAVE TRENDED FURTHER SOUTH WITH THE MOISTURE ASSOCIATED WITH FORMER TD NUMBER 5. A WAVE OF LOW PRESSURE MOVING ALONG THE BAROCLINIC ZONE WOULD STAY SOUTH OF THE REGION ACCORDING TO THE GFS AND CANADIAN GGEM. THE ECMWF STAYED FAR ENOUGH NORTH TO KEEP CHC POPS IN WED NIGHT INTO THU. WE DID NOT WANT TO DEVIATE FROM PERSISTENCE...18Z HPC DATA...AND THE GLOBAL ENSEMBLES BY BUYING INTO THE SOUTHERN TRACK YET FOR THU. WE KEPT CHC POPS THROUGH THE DAY UNTIL THIS TREND CONTINUES A FEW MORE CYCLES. THU NIGHT INTO FRI...A NRN STREAM SHORTWAVE TROUGH ARRIVES FROM SOUTHEASTERN CANADA AND THE ERN GREAT LAKES REGION. THE TIMING VARIES ON THE FRONTAL PASSAGE WITH THE TROUGH AMONG THE MEDIUM RANGE GUIDANCE. THE CANADIAN GGEM AND GFS ARE A BIT FASTER THAN THE ECMWF. THE MOISTURE IS LIMITED WITH THE BOUNDARY...AND THE INSTABILITY LOOKS MEAGER. WE KEPT A SLIGHT CHC OF SHOWERS AND TSRAS FROM THE CAPITAL REGION SOUTH...AND LOW CHC VALUES TO THE NORTH. THE BEST FORCING AND DYNAMICS STAY NORTH AND EAST OF THE REGION. FRI NIGHT THRU THE WEEKEND...THE LATEST GFS LOOKS LIKE AN OUTLIER COMPARED THE CANADIAN GGEM/ECMWF/ENSEMBLES FOR THE STRETCH. IT HAS A CLOSED LOW IN A PROGRESSIVE MID LEVEL TROUGH QUICKLY APPROACH FROM THE UPPER MS RIVER VALLEY FRI NIGHT INTO SATURDAY WITH VERY UNSETTLED WX FOR THE WEEKEND. THE ECMWF/CANADIAN GGEM/HPC GRAPHICS SHOW LOW AND MID LEVEL RIDGING SETTING UP OVER THE NORTHEAST TO OPEN THE WEEKEND WITH FAIR AND DRY WX...WHILE A SFC WAVE AND ITS ASSOCIATED UPPER LEVEL TROUGH BRING A THREAT OF SHOWERS/ISOLD TSRAS ON SUNDAY. WE STUCK CLOSE TO HPC WITH A DRY START TO THE WEEKEND WITH SOME UNSETTLED WX TO CLOSE IT. TEMPS LOOK SEASONABLE FOR THE LONG TERM WITH HIGHS GENERALLY IN THE U70S TO L80S IN THE VALLEYS...AND LOWER TO M70S OVER THE MTNS. LOWS WILL GENERALLY BE IN THE M50S TO L60S IN THE VALLEYS...AND U40S TO M50S IN THE MTNS. THE WARMEST DAY OF THE EXTENDED LOOKS TO BE ON FRI WITH H850 TEMPS OF 16 TO 18 C AND GOOD MIXING WITH A FRONTAL PASSAGE COULD YIELD AT LEAST SOME MID 80S SOUTH OF THE CAPITAL REGION. && .AVIATION /12Z MONDAY THROUGH FRIDAY/... A WARM FRONT CONTINUES TO SLOWLY LIFT N/NE ACROSS WRN NY AND PA EARLY THIS MORNING...IGNITING SOME SHOWERS AND THUNDERSTORMS ACROSS THE ADIRONDACKS AND CENTRAL NY AS OF 12Z. A COLD FRONT WILL MOVE THROUGH THIS AFTERNOON WITH A BAND OF -SHRAS/-TSRAS. HIGH PRESSURE WILL BUILD IN FROM THE UPPER MS RIVER VALLEY MON NIGHT. THE MIST AND STRATUS CURRENTLY AFFECTING ALL THREE TERMINALS WILL TAKE A WHILE TO BURN OFF AHEAD OF THE COLD FRONT WHICH IS TRAVELING CLOSELY BEHIND THE WARM FRONT. IFR CIGS EXPECTED AT KGFL AND KALB THE BEGINNING OF THE TAF PERIOD IMPROVING TO MVFR AROUND 14Z/15Z. KGFL AND KPOU EXPECTING MVFR VSBYS THRU 14Z. BROKEN LINE OF -SHRA/-TSRA EXPECTED AT KGFL AROUND 14Z...CONTINUING TO MOVE SOUTHEASTWARD INTO KALB AROUND 16Z. BEHIND THIS LINE...VFR CONDITIONS EXPECTED AT ALL TERMINALS BY EARLY AFTERNOON BUT HAVE INCLUDED VCSH AND CB AT ALL TERMINALS THROUGH THE LATE AFTERNOON/EARLY EVENING AS COLD FRONT EXPECTED TO MOVE THROUGH AND GENERATE SOME MORE -SHRA/-TSRA. WITHIN -SHRA/-TSRA HEAVY RAIN COULD REDUCE VSBYS. BEHIND THE COLD FRONT...DRY AIR ALOFT AND CLEARING SKIES WILL ALLOW FOR SOME BR TO DEVELOP AS WINDS SUBSIDE AFTER MIDNIGHT. EXPECT THE WINDS TO INCREASE TO THE S/SW LATE THIS MORNING AT AROUND 10 KTS...WITH WIND GUSTS AT KALB 15-20KTS. STRONGER WINDS MAY OCCUR WITH ANY THUNDERSTORMS THIS AFTERNOON.

SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG AND AHEAD OF THE COLD FRONT...AND SOME OF THE THUNDERSTORMS MAY PRODUCE GUSTY WINDS...HEAVY RAIN AND HAIL. HIGH PRESSURE WILL THEN BUILD INTO OUR REGION LATER TONIGHT AND LAST THROUGH WEDNESDAY MORNING GIVING US DRY AND SEASONABLE CONDITIONS. RELATIVE HUMIDITIES WILL ONLY DROP TO 50 TO 75 PERCENT TODAY...INCREASE TO 90 TO 100 PERCENT TONIGHT AND DROP TO 30 TO 45 PERCENT TUESDAY AFTERNOON. WINDS WILL BE SOUTH TO SOUTHWEST AT 10 TO 15 MPH TODAY WITH HIGHER GUSTS IN THUNDERSTORMS...WEST TO SOUTHWEST AT 5 TO 10 MPH THIS EVENING BECOMING LIGHT AND VARIABLE OVERNIGHT...AND WEST TO SOUTHWEST AT 5 TO 15 MPH ON TUESDAY WITH GUSTS UP TO 25 MPH ACROSS THE HIGHER TERRAIN. && .HYDROLOGY... A COLD FRONT IN THE EASTERN GREAT LAKES EARLY THIS MORNING WILL MOVE EAST TODAY REACHING CENTRAL NEW YORK AROUND MID DAY...AND THEN PUSHING THROUGH EASTERN NEW YORK AND ADJACENT WESTERN NEW ENGLAND EARLY THIS EVENING. SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG AND AHEAD OF THE COLD FRONT. SOME OF THE SHOWERS AND THUNDERSTORMS COULD CONTAIN HEAVY RAIN...CAPABLE OF PRODUCING LOCALIZED RAINFALL OF ONE TO TWO INCHES THIS AFTERNOON. THIS WOULD RESULT IN PONDING OF WATER ON ROADWAYS AND IN POOR DRAINAGE AREAS AND SHARP RISES ON SMALL CREEKS. HOWEVER...AVERAGE RAINFALL AMOUNTS WITH THIS SYSTEM WILL BE A QUARTER TO A HALF INCH...SO MAINSTREAM RIVERS WILL LIKELY SEE LITTLE IN THE WAY OF RISES.
