NWS Albany, NY wrote its last area forecast discussion before the first event at May 8, 9:33 AM EST, 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 1033 AM EDT TUE MAY 8 2012 .SYNOPSIS... AN AREA OF LOW PRESSURE AND ITS ASSOCIATED FRONTAL BOUNDARIES WILL CONTINUE TO BRING WIDESPREAD RAINFALL TO THE AREA TODAY INTO TONIGHT. SCATTERED SHOWERS WILL PERSIST FOR WEDNESDAY AND THURSDAY...BEFORE HIGH PRESSURE RETURNS MORE SUNSHINE AND SEASONABLE TEMPERATURES BACK TO OUR REGION HEADING INTO THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... COOL...WET DAY ON TAP AS RAIN CONTINUES AS LOW PRESSURE LOCATED OVER THE EASTERN GREAT LAKES MOVES GRADUALLY NORTHEASTWARD TODAY AND TONIGHT BRINGING ITS ASSOCIATED FRONTAL BOUNDARIES THROUGH THE REGION...WARM FRONT TODAY AND COLD FRONT TONIGHT. OVERALL FORECAST LOOKS GOOD. MADE SOME ADJUSTMENTS TO TEMPERATURES (COOLER) AND DEW POINTS. MINOR ADJUSTMENTS TO POPS...SHOWERS MOVING BACK INTO THE SOUTHERN MOST PORTION OF THE FORECAST AREA...WHERE THEY HAD THE LEAST AMOUNT OF RAINFALL. REFER TO PUBLIC INFORMATION STATEMENT FOR RAINFALL REPORTS. PWATS ARE EXPECTED TO CONTINUE TO INCREASE TO 1.25 TO NEARLY 1.50 INCH BY EARLY THIS AFTERNOON AS THE WARM FRONT CONTINUES TO LIFT NORTHEAST TOWARD OUR REGION. SHOWALTER INDICES DROP TO NEAR ZERO BY LATE IN THE DAY...BUT WITH MLMUCAPES 100 J/KG OR LESS HAVE DECIDED TO KEEP THE SLIGHT CHANCE OF THUNDER OUT OF THE FORECAST FOR THIS EVENING. SOUTH TO SOUTHEAST WINDS ARE EXPECTED TO INCREASE TO 10 TO 20 MPH WITH GUSTS UP TO 30 MPH AS PRESSURE GRADIENT TIGHTENS ACROSS FA. TONIGHT...THE STEADIEST AND HEAVIEST RAIN IS EXPECTED TO OCCUR DURING THE EVENING WITH THE RAIN TAPERING TO MAINLY SCATTERED SHOWERS AFTER MIDNIGHT AS WARM FRONT LIFTS OFF TO OUR NORTHEAST AND COLD FRONT SWEEPS ACROSS AT LEAST NORTHWESTERN HALF OF FA BY MORNING. EXPECT LOWS IN THE UPPER 40S TO MID 50S. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... WEDNESDAY...LOOKS TO BE MAINLY CLOUDY BUT FAIRLY MILD IN THE WAKE OF THE FIRST COLD FRONT WITH ONLY SCATTERED SHOWERS WITH HIGHEST POPS ACROSS SOUTHEASTERN PORTION OF FA. A FEW BREAKS OF SUN ARE POSSIBLE LATE IN THE DAY ACROSS THE WESTERN MOHAWK VALLEY AND WESTERN ADIRONDACKS. HIGHS ON WEDNESDAY ARE EXPECTED TO BE IN THE MID 60S TO MID 70S. WEDNESDAY NIGHT AND THURSDAY...THE SECONDARY COLD FRONT/TROUGH IS EXPECTED TO CROSS THE FA ON WEDNESDAY NIGHT AS THE FIRST COLD FRONT REMAINS ANCHORED ALONG THE EASTERN SEABOARD WITH A WAVE OF LOW PRESSURE LIFTING NORTHEAST ALONG IT. THE GFS/NAM/ECMWF/GEM ARE FAIRLY CONSISTENT WITH MOISTURE FROM SECONDARY WAVE JUST BRUSHING SOUTHEAST CORNER OF FA WEDNESDAY NIGHT INTO THURSDAY MORNING. HOWEVER...THERE MAY BE SOME UPSLOPE SHOWERS ACROSS PORTIONS OF THE SOUTHERN GREEN MOUNTAINS AND NORTHERN BERKSHIRES ON THURSDAY AS SURFACE LOW MOVES INTO THE CANADIAN MARITIMES AND UPPER TROUGH SWINGS THROUGH FA WITH STRENGTHENING VORT AXIS. HAVE SLIGHTLY HIGHER QPF AMOUNTS ON THU ACRS THESE AREAS WITH UP TO TWO TENTHS OF AN INCH. EXPECT LOWS WEDNESDAY NIGHT IN THE UPPER 30S TO LOWER 50S WITH HIGHS ON THURSDAY IN THE MID 50S TO MID 60S. THURSDAY NIGHT...DRIER AIR WILL FINALLY START TO WORK TOWARDS THE FA AS THE NOSE OF A RIDGE OF HIGH PRESSURE ACROSS THE OHIO VALLEY BUILDS NORTHEASTWARD INTO WESTERN AND CENTRAL NEW YORK. WILL STILL LEAVE SLIGHT CHANCE TO LOW CHANCE POPS IN FOR THURSDAY NIGHT AS UPPER TROUGH AXIS SITUATED JUST TO OUR EAST BY FRIDAY MORNING. EXPECT LOWS THURSDAY NIGHT IN THE UPPER 30S TO MID 40S. && .LONG TERM /FRIDAY THROUGH MONDAY/... THE EXTENDED OPENS WITH AN UPPER LEVEL TROUGH OVER THE NORTHEAST...WHILE SOME RIDGING OVER THE UPPER MIDWEST AND THE MS RIVER VALLEY WILL BE ATTEMPTING TO BUILD EASTWARD FOR NEXT WEEKEND. THE UPPER TROUGH AXIS IS EAST OF MOST OF THE FORECAST AREA ON FRI. THE COLD POOL ALOFT LINGERS A BIT OVER WRN NEW ENGLAND. A SLIGHT CHC OF SHOWERS WAS KEPT IN THE FORECAST FOR WRN NEW ENGLAND...AND PERHAPS THE N-CNTRL TACONICS. STEEP LAPSE RATES COMBINED WITH THE DIURNAL HEATING WILL ALLOW SOME ISOLD SHOWERS. THE REST OF THE FCST AREA SHOULD REMAIN DRY WITH SFC HIGH PRESSURE RIDGING IN FROM THE OHIO VALLEY AND THE GREAT LAKES REGION. MAX TEMPS WILL BE SEASONABLE WITH GENERALLY MID AND U60S IN THE VALLEY LOCATIONS...AND U50S TO M60S OVER THE HILLS AND MTNS. THERE MAYBE SOME SPOTTY 70F READINGS IN THE MID HUDSON VALLEY. FRI NIGHT THROUGH SAT NIGHT...TRANQUIL PERIOD WITH HIGH PRESSURE MOVING EASTWARD OVER THE MID ATLANTIC REGION TO OPEN THE WEEKEND. MID AND UPPER HEIGHTS RISE WITH A RIDGE SETTING UP OVER THE EAST COAST BRIEFLY. MOSTLY CLEAR SKIES AND LIGHT/CALM WINDS WILL ALLOW MIN TEMPS TO BE IN THE LOWER TO M40S IN THE VALLEYS EACH NIGHT...AND 30S OVER THE MTNS. SATURDAY LOOKS LIKE A LOVELY DAY BASED ON THE LATEST MEDIUM RANGE GUIDANCE/ENSEMBLES/HPC GRAPHICS WITH H850 TEMPS IN THE +4 TO +6 C RANGE...EXPECT HIGHS TO BE SLIGHTLY ABOVE NORMAL WITH U60S TO L70S IN THE VALLEYS...AND LOWER TO M60S OVER THE MTNS. SUNDAY INTO MONDAY...THE MEDIUM RANGE GUIDANCE DIVERGES A BIT ON WHAT TO DO WITH A SLOW MOVING COLD FRONT...AND A NORTHERN STREAM SHORT-WAVE. THE ECMWF WOULD BRING A SLIGHT TO LOW CHANCE OF SHOWERS TO THE NRN HALF OF THE FCST AREA ON SUNDAY. THE CANADIAN GGEM WOULD HAVE A SLIGHT TO LOW CHANCE OF SHOWERS WITH A THERMAL TROUGH....AND THE GFS WOULD HAVE THE RIDGE AXIS HOLD TOUGH TO CLOSE THE WEEKEND WITH A CUTOFF FORMING EAST OR CAPE COD. HPC WOULD HAVE THE COLD FRONT WITH WEAK SYNOPTIC FORCING HANG UP NEAR THE ST LAWRENCE RIVER VALLEY. WE KEPT MOST OF SUNDAY DRY...WITH JUST A SLIGHT CHANCE OF A SHOWERS WEST OF THE CAPITAL DISTRICT...AND THE HUDSON RIVER VALLEY. SUNDAY NIGHT INTO MONDAY...WE EXPANDED SLIGHT TO LOW CHANCE POPS OVER THE ALY FCST AREA WITH THE FRONT BECOMING DIFFUSE AND STATIONARY IN THE NY/NEW ENGLAND CORRIDOR. WEAK IMPULSES IN THE SW FLOW ALOFT COULD SPAWN ISOLD-SCT SHOWERS. H850 TEMPS RISE CLOSE TO +7 TO +9 C AHEAD OF THE FRONT...SO TEMPS LOOK SLIGHTLY ABOVE NORMAL EACH DAY. OVERALL...TEMPS LOOK NORMAL TO SLIGHTLY ABOVE NORMAL...AND PCPN BELOW NORMAL IN THE EXTENDED FCST PERIOD. && .AVIATION /14Z TUESDAY THROUGH SATURDAY/... LOW PRESSURE WAS LOCATED OVER THE EASTERN GREAT LAKES AND WILL CONTINUE TO MOVE GRADUALLY EASTWARD TODAY AND TONIGHT. RAINFALL WILL CONTINUE AHEAD OF ITS WARM FRONT TODAY WITH ITS COLD FRONT MOVING THROUGH TONIGHT. HAVE VFR CONDITIONS AT KALB...KPOU AND KPSF WITH MVFR AT KGFL AT THIS TIME (10AM/14Z).

BUFKIT PROFILES INDICATE STRONG LOW LEVEL WINDS OVR THE AREA INTO THIS AFTERNOON. THE WINDS WILL BECOME LIGHT AND VARIABLE AFTER 00Z/WED. .OUTLOOK... WED-THU...VFR-MVFR. CHC -SHRA. FRI-SAT...VFR. NO SIG WX. && .FIRE WEATHER... WET FLAG CONDITIONS ARE EXPECTED TO PERSIST THROUGH AT LEAST THIS EVENING. A LOW PRESSURE SYSTEM WILL MOVE NORTHEAST FROM THE EASTERN GREAT LAKES EARLY THIS MORNING LIFTING A WARM FRONT TOWARDS OUR REGION. THE WARM FRONT AND ASSOCIATED LOW PRESSURE SYSTEM ARE EXPECTED TO BRING A WIDESPREAD RAINFALL TO THE REGION THROUGH THIS EVENING WITH THE RAINFALL HEAVY AT TIMES ESPECIALLY ACROSS NORTHERN PARTS OF THE AREA. SCATTERED SHOWERS WILL PERSIST FOR WEDNESDAY AND THURSDAY...BEFORE HIGH PRESSURE RETURNS MORE SUNSHINE AND SEASONABLE TEMPERATURES BACK TO OUR REGION HEADING INTO THE WEEKEND. RELATIVE HUMIDITIES ARE EXPECTED TO ONLY DROP TO 55 TO 80 PERCENT TODAY...RECOVER TO 85 TO 100 PERCENT TONIGHT...AND DROP TO 40 TO 55 PERCENT ON WEDNESDAY. WINDS ARE EXPECTED TO SOUTH TO SOUTHEAST AT 10 TO 20 MPH WITH GUSTS UP TO 30 MPH TODAY...SOUTH TO SOUTHWEST AT 5 TO 15 MPH TONIGHT...AND WEST TO SOUTHWEST AT 5 TO 15 MPH ON WEDNESDAY. && .HYDROLOGY... AT THIS TIME NOT EXPECTING ANY HYDRO ISSUES ACROSS THE HSA...ALTHOUGH THE MMEFS INDICATES THAT A FEW POINTS ACROSS THE NORTHERN PORTION OF THE HSA IN THE ADIRONDACKS AND BERKSHIRES HAVE A 30 PERCENT CHANCE OF REACHING ACTION STAGE DURING THE MID WEEK PERIOD. THE WETTEST PERIOD DURING MID WEEK IS EXPECTED TO BE FROM NOW THROUGH THIS EVENING WITH SCATTERED SHOWERS THEN CONTINUING FROM LATER TONIGHT INTO THURSDAY...BEFORE DRY WEATHER RETURNS TO END THE WEEK. IT APPEARS THE HEAVIEST QPF WILL BE ACROSS AREAS FROM THE NORTHEAST CATSKILLS TO THE NORTHERN BERKSHIRES AND POINTS NORTH WHERE 1.25 TO 2 INCHES WITH LOCALLY HIGHER AMOUNTS IS EXPECTED THROUGH LATE TONIGHT. THE SOUTHEAST PORTION OF THE FA IS EXPECTED TO HAVE AMOUNTS RANGING FROM AROUND HALF AN INCH TO SLIGHTLY OVER AN INCH.
