NWS Albany, NY wrote its last area forecast discussion before the first event at Sep 3, 6:56 PM EST, 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 756 PM EDT WED SEP 3 2008 .SYNOPSIS... AN UPPER LEVEL DISTURBANCE WILL PRODUCE ISOLATED SHOWERS AND THUNDERSTORMS MAINLY FROM THE HUDSON VALLEY EASTWARD INTO THIS EVENING. A WEAK COLD FRONT WILL THEN GRADUALLY MOVE SOUTHWARD THROUGH THE REGION THURSDAY AFTERNOON...POSSIBLY TRIGGERING ISOLATED SHOWERS. VERY WARM AND INCREASINGLY HUMID AIR WILL MOVE IN FOR FRIDAY...BEFORE TROPICAL STORM HANNA IMPACTS THE REGION WITH UNSETTLED WEATHER THIS WEEKEND. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... ISOLATED SHOWERS AND MAYBE A ROGUE THUNDERSTORM WILL PERSIST THROUGH ABOUT 8 OR 9 PM...BEFORE DISSIPATING DUE TO LOSS OF DAYTIME HEATING. SO FAR A FEW ECHOES HAVE POPPED UP OVER THE HIGHER TERRAIN OF THE GREEN MOUNTAINS AND BERKSHIRES...WITH CYCLONIC FLOW AROUND A SLOW MOVING UPPER LOW CENTERED ACROSS THE EASTERN ATLANTIC. SBCAPE VALUES RATHER IMPRESSIVE AROUND 1500 J/KG...SO WILL CONTINUE TO MENTION THUNDER. GUSTY WINDS AND SMALL HAIL WILL BE POSSIBLE IN ONE OR TWO OF THE TALLER STORMS. THIS UPPER LOW IS FORECAST TO FINALLY MOVE EASTWARD TONIGHT. OVERNIGHT SOME PATCHY VALLEY FOG WILL DEVELOP...WITH MIN TEMPS MAINLY IN THE MID 50S TO LOWER 60S. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... THE UPPER LOW NEAR THE NEW ENGLAND COAST SHOULD FINALLY PULL AWAY INTO THE CANADIAN MARITIMES BY THUR MORNING AS IT GETS NUDGED EASTWARD BY A TROF ADVANCING THROUGH THE UPPER MIDWEST. AN UPPER RIDGE WILL START TO BUILD ACROSS OUR REGION DURING THE DAY THUR...AS A WEAK COLD FRONT AT THE SURFACE PASSES THROUGH. WITH LACK OF DYNAMICS AND WIND FLOW THE FRONT SHOULD PASS THROUGH WITH LITTLE FANFARE. WILL CONTINUE TO MENTION SLIGHT CHANCE POPS SINCE THERE WILL BE SOME LOW LEVEL MOISTURE TO WORK WITH AS DEWPOINTS CLIMB INTO THE 60S. SINCE UPPER LEVEL TEMPS WILL BE WARMING...NOT MUCH INSTABILITY WILL DEVELOP SO WILL NOT MENTION ANY THUNDER. MAX TEMPS WILL CONTINUE TO RUN ABOVE AVERAGE WITH MID TO UPPER 80S WIDESPREAD IN THE VALLEYS. THERE COULD BE SOME 90 DEGREE READINGS IN THE MID HUDSON VALLEY. THE WEAK COLD FRONT WILL ACTUALLY BECOME DIFFUSE AND STALL ACROSS THE AREA THUR NIGHT...SO THERE WILL BE NO APPRECIABLE CHANGE IN AIR MASS. IF ANYTHING...EVEN WARMER AND MORE HUMID AIR WILL ADVECT NORTHWARD BY FRI AS THE UPPER RIDGE TAKES HOLD AND THE SURFACE FRONT LIFTS BACK NORTHWARD AS A WARM FRONT AND SOUTHERLY FLOW INCREASES. THIS ADDITIONAL WARM SURGE WILL ALLOW TEMPS TO POSSIBLY REACH 90 AS FAR NORTH AS THE CAPITAL REGION. THE RECORD HIGH FOR ALBANY ON FRI IS 91...AND WE COULD GET VERY CLOSE. WILL CONTINUE TO MENTION DRY FORECAST THROUGH FRI...WITH A STRONG CAP IN PLACE. IT APPEARS TRANQUIL CONDITIONS WILL PERSIST THROUGH AT LEAST FRI EVENING...AS WE WILL BE IN A COL BETWEEN THE REMNANTS OF GUSTAV ACROSS QUEBEC AND HANNA IN THE CAROLINAS...AND A RIDGE OF HIGH PRESSURE ACROSS THE WESTERN GREAT LAKES AND ANOTHER ACROSS THE EASTERN ATLANTIC. WILL MENTION CHANCE TO LIKELY POPS FROM NORTH TO SOUTH LATE FRI NIGHT...AS THE GFS IS HINTING AT SOME PRECIP DEVELOPING ASSOC WITH A PREDECESSOR RAIN EVENT /PRE/. CSTAR RESEARCH HAS SHOWN THAT A PRE CAN DEVELOP WELL AHEAD OF A TROPICAL SYSTEM IN THE RIGHT ENTRANCE REGION OF AN UPPER JET ACROSS QUEBEC/CANADIAN MARITIMES. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... THIS PERIOD IS ENTIRELY DEPENDENT ON THE FUTURE TRACK AND EVOLUTION OF HANNA...AND FOLLOWS CLOSELY TO THE NHC TRACK. SHOULD THIS COME TO FRUITION...THE BEST CHANCE FOR WIDESPREAD...HEAVY RAIN APPEARS TO BE SAT INTO SAT NIGHT. IN ADDITION...GUSTY WINDS WILL BE POSSIBLE ACROSS PORTIONS OF THE MID HUDSON VALLEY...SW MA AND NW CT...PARTICULARLY ACROSS THE HIGHER ELEVATIONS OF THE TACONICS...SOUTHERN BERKS AND LITCHFIELD HILLS. RAINFALL AMOUNTS OF 1-3 INCHES ARE POSSIBLE...WITH THE HIGHEST TO THE S/E. TEMPERATURES WILL ALSO BE HIGHLY DEPENDENT ON ULTIMATE TRACK OF HANNA AS WELL...AND WE HAVE GENERALLY SIDED WITH HPC GUIDANCE. THIS YIELDS MAXES IN THE 60S ACROSS THE HIGHER TERRAIN...WITH LOWER/MID 70S IN THE VALLEYS...ESP TO THE S/E. IT SHOULD BE NOTED THAT...SHOULD WIDESPREAD RAINFALL COME TO FRUITION BY SAT AFTERNOON...TEMPS ON THE N SIDE OF FRONT COULD BE CONSIDERABLY COOLER...PERHAPS FALLING THROUGH THE 60S DURING SAT AFTN...AND THIS COULD EVEN INCLUDE THE CAPITAL REGION EXTENDING AS FAR S AS THE MID HUDSON VALLEY AS INCREASING LOW/MID LEVEL FRONTOGENETICAL FORCING POTENTIALLY ALLOWS SHALLOW RAIN COOLED AIR MASS TO SEEP SOUTHWARD. RAIN SHOULD TAPER TO SCATTERED SHOWERS BY SUN...WITH SOME CLEARING POSSIBLE BY AFTERNOON. MAX TEMPS SHOULD MAINLY BE IN THE 70S IN THE VALLEYS...WITH 60S ACROSS THE HIGHER TERRAIN OF THE NORTH COUNTRY. THE REMNANTS OF HANNA HAVING DEPARTED...HIGH PRESSURE PARKED OVER THE NORTHEAST SUNDAY NIGHT AND MON GIVES WAY TO A COLD FRONT FROM THE WEST ON TUE. SLGT CHC POPS ACROSS CWA INCREASE TO CHC FOR MON NGT THRU TUE NGT PERIOD...THEN BACK TO SLGT CHC AS HIGH PRESSURE BUILDS BACK IN BEHIND FRONT. WENT WITH GFS TEMPS...WHICH ARE A FEW DEGREES LOWER THAN THE MEX. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... TEMPS EXPECTED TO DROP VERY QUICKLY AT BEGINNING OF TAF PERIOD WITH VERY LITTLE CLOUD COVER. THIS WILL RESULT IN AT LEAST MVFR FOG DEVELOPING BY 06Z AT ALL AIRPORTS. GFL WILL EASILY GET DOWN TO IFR. THE ABUNDANT SUNSHINE WILL RESULT IN RAPID WARMING FRI AM...SO ALL FOG WILL BE BURNED OFF BY 12Z. A WEAKENING COLD FRONT SHOULD COME THROUGH DRY BY 00Z TUE...BUT MAY NOT REACH POU. HAVE INCLUDED CB THERE... BUT NO MENTION OF SHRA ATTM. SO...OTHER THAN TONIGHTS FOG...VFR CONDITIONS THROUGH TAF PERIOD. HIGH PRESSURE RIFGING IN FROM THE ATLANTIC AROUND THE NORTH SIDE OF APPROACHING HANNA WILL KEEP CONDITIONS DIURNALLY VFR ON FRI AND WITH LESS OF AN OVERNIGHT FOG PROBLEM THU NGT. HANNA SLOWS ANOTHER APPROACHING FRONT ON SATURDAY...THE COMBINED EFFECTS LIKELY TO PRODUCE PERIODS OF IFR OVER THE WEEKEND...AT LEAST THE EARLY PART. SUNDAY IS IFFY WITH MODELS NOT AGREEING ON HANNAS DEPARTURE TIME... BUT ALL AGREE THAT HIGH PRESSURE IS BACK IN CONTROL BY MON. OUTLOOK... THU NGT...NO SIG WX...AREAS MVFR FOG. FRI...VFR...NO WX. FRI NIGHT-SAT...GRADUALLY DETERIORATING TO MVFR/IFR...INCR CHC OF SHRAS. LATE SAT-EARLY SUN...MVFR/IFR/LIFR CIGS/VSBYS IN STRATIFORM RAINFALL POSSIBLY HVY AT TIMES. LATE SUN-MON...IMPROVING TO MVFR/VFR...POSS MORNING MIST/FOG. && .FIRE WEATHER... ISOLATED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE FROM THE HUDSON VALLEY EASTWARD INTO THIS EVENING BEFORE DIMINISHING. A WEAK COLD FRONT WILL THEN GRADUALLY MOVE SOUTHWARD THROUGH THE REGION THURSDAY AFTERNOON...POSSIBLY TRIGGERING ISOLATED SHOWERS. WARM AND HUMID CONDITIONS WILL PERSIST THROUGH THE END OF THE WEEK. RELATIVE HUMIDITY VALUES WILL RECOVER TO NEAR 100 PERCENT TONIGHT...THEN DROP TO AROUND 45 TO 55 PERCENT IN THE VALLEYS AND 55 TO 65 PERCENT ACROSS THE HIGHER ELEVATIONS. WINDS WILL BE LIGHT AND VARIABLE TONIGHT...BECOMING MAINLY WESTERLY LESS THAN 10 MPH. && .HYDROLOGY... OTHER THAN A FEW ISOLATED SHOWERS AND THUNDERSTORMS THIS AFTERNOON...LITTLE IN THE WAY OF PRECIPITATION IS FORECAST THROUGH FRIDAY. BASIN AVERAGE PRECIPITATION WILL BE LIGHT TODAY...BUT A FEW LOCALLY HEAVY DOWNPOURS MAY OCCUR. LITTLE IN THE WAY OF STREAM RESPONSE IS EXPECTED AS SURFACE SOIL MOISTURE CONDITIONS ARE VERY DRY. NEXT SIGNIFICANT RAINFALL IS EXPECTED THIS WEEKEND WITH TROPICAL STORM HANNA. MODELS INDICATE THAT RAINFALL MAY BEGIN WELL IN ADVANCE OF THE STORM WITH A TROUGH OF LOW PRESSURE AHEAD OF THE STORM. MODEL CONSENSUS SUGGESTS THAT A SOUTHWEST TO NORTHEAST SWATH OF 3 TO 5 INCH TOTAL RAINFALL IS POSSIBLE FROM HANNA. LOCATION OF THIS SWATH OF HEAVY RAIN IS STILL IN QUESTION AT THIS TIME...BUT WE BELIEVE THE BAND OF HEAVY RAIN WILL BE SOUTH AND EAST OF ALBANY NEW YORK...WITH AMOUNTS DECREASING TO THE NORTH AND WEST WITH THE WESTERN ADIRONDACK REGION ONLY RECEIVING AROUND AN INCH OF PRECIPITATION. MAIN STEM RIVER FLOODING IS NOT EXPECTED AT THIS TIME FROM HANNAS PRECIPITATION...BUT LOCALIZED URBAN...SMALL STREAM AND FLASH FLOODING IS POSSIBLE. PERSONS LIVING IN FLOOD PRONE AREAS SHOULD KEEP UP WITH LATEST FORECASTS FOR HANNA AND ASSOCIATED RAINFALL.
