AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
405 PM EDT WED MAY 31 2006

.SYNOPSIS...A WARM AND HUMID AIR MASS WILL REMAIN OVER NEW YORK AND
NEW ENGLAND OVERNIGHT INTO THE END OF THE WORK WEEK. A COLD FRONT
WILL BE SLOWLY APPROACHING FROM THE SAINT LAWRENCE AND OHIO RIVER
VALLEYS THURSDAY MORNING. THIS BOUNDARY WILL GENERATE SEVERAL ROUNDS
OF SHOWERS AND THUNDERSTORMS THURSDAY INTO FRIDAY MORNING. THE FRONT
WILL STALL NEAR THE SOUTHERN NEW ENGLAND COAST FRIDAY MORNING...AS A
WAVE OF LOW PRESSURE MOVES ALONG THE BOUNDARY FROM THE MID ATLANTIC
STATES. THE LOW WILL PRODUCE PERIODS OF RAIN...ESPECIALLY SOUTH AND
EAST OF THE CAPITAL REGION INTO SATURDAY MORNING.

THE BIG PICTURE...A LONG WAVE HIGH AMPLITUDE RIDGE REMAINS IN PLACE
OVER THE EAST COAST OF NORTH AMERICA.  A TROUGH OVER HUDSON BAY AND
CNTRL CANADA AT 500 MB IS TRYING TO ERODE THE RIDGE.  A SERIES OF
SHORTWAVE IMPULSES ARE MOVING AROUND THE RIDGE.  THE MOST POTENT ONE
IS MOVING THROUGH THE MIDWEST...WHERE A SFC COLD FRONT IS TIED TO
THE  H500-700 TROUGH.  THE EAST COAST WILL FALL UNDER THE INFLUENCE
OF AN ACTIVE W/SW H500 FLOW INTO THE WEEKEND WITH THE SFC FRONT
BEING SLOWED DOWN BY THEN FLATTENING LONGWAVE RIDGE.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...
CURRENTLY THE KENX RADAR SHOWS A LINE/CLUSTER OF CONVECTION
IMPACTING THE NRN REACHES OF THE LAKE GEORGE AREA...NRN NY...AND THE
CHAMPLAIN VALLEY. THIS APPEARS TO BE TIED TO AN OLD OUTFLOW BOUNDARY
OR LAKE BREEZE FROM PREVIOUS CONVECTION UPSTREAM. PENNY SIZE HAIL
WAS REPORTED AT NORTH CREEK. FURTHER UPSTREAM...THUNDERSTORMS AT
1915Z ARE FIRING OVER CNTRL NY...WEST OF KBGM...WHERE MAXIMUM
HEATING HAS OCCURRED WHICH HAS YIELDED SBCAPES IN THE 2000+J/KG
RANGE. SFC TEMPS ARE GENERALLY IN THE +30C-+33C RANGE WITH SFC
DEWPOINTS IN THE 60S.  THIS APPEARS TO BE ANOTHER BOUNDARY EVIDENT
IN THE SATELLITE/WATER VAPOR IMAGERY.  THE MOST IMPRESSIVE H500
SHORTWAVE WITH ONGOING CONVECTION IS OVER NE OHIO ALONG A
KERI-KCLE-KCMH AXIS.  WE ARE EXPECTING A CLUSTER OF CONVECTION TO
DEVELOP IN THE WRN-CNTRL NY AREA LATE THIS AFTERNOON AND TO CONTINUE
INTO THIS EVENING. 0-6 KM BULK SHEAR VALUES ARE ONLY IN THE 20-25 KT
RANGE.  THERE IS GOOD UNIDIRECTIONAL SPEED SHEAR IN THE H500-700
LAYER.  HOWEVER...MODEL SOUNDINGS INDICATED SBCAPE VALUES OF
1000-2000 J/KG IN PLACE OVER THE WRN REACHES OF THE FCST AREA.  LESS
IN THE HUDSON VALLEY...BECAUSE THE STRATUS TOOK QUITE A WHILE TO
BURN OFF TODAY. PRECIPITABLE WATER VALUES ARE ON THE INCREASE TOO.
WE ARE EXPECTING VALUES IN THE 1.50-2.00 RANGE TO PERSIST OVERNIGHT
INTO FRIDAY. THIS ABOUT 200% OF NORMAL. WE HAVE PLACED ENHANCED
WORDING FOR SMALL HAIL...GUSTY WINDS AND FRQT LIGHTNING AND HEAVY
DOWNPOURS WEST OF THE HUDSON RIVER VALLEY 20Z-04Z TONIGHT. THE
CONVECTION SHOULD START TO DIE THEREAFTER. THE GFS CONTINUES A 2+
INCH BULLSEYE FROM THE CAPITAL REGION S/SW INTO THE CATSKILLS. THIS
APPEARS TO BE OVERDONE SOME. POTENTIALLY CONVECTIVE FEEDBACK. THE
NAM HAS SLIGHTLY GREATER SBCAPE VALUES DUE THE EXCESSIVELY HIGH
DEWPOINTS. WE HAVE LIKELY AND HIGH CHANCE POPS VALUES OVERNIGHT.

ON THU..THE SFC COLD FRONT MAKES IT TO ABOUT CNTRL NY BY NOONTIME
ACCORDING TO THE GFS. THE NAM IS A BIT SLOWER. OVERALL...THE
MAJORITY OF THE SHORT RANGE MODELS ARE SLIGHTLY DIFFERENT WITH THE
POSITION OF THE FRONT THU INTO FRIDAY. WE ARE EXPECTING ANOTHER
ROUND OF SHOWERS AND THUNDERSTORMS. H850 THETA-E VALUES WILL
CONTINUE TO BE IN TH 330-335K RANGE WITH PWATS AROUND 1.75. HEAVY
DOWNPOURS WILL BE POSSIBLE. GFS SBCAPE VALUES FROM ALY SOUTH AND
EAST ARE IN THE 1000-2000J/KG RANGE. THIS MIGHT BE A BIT EXCESSIVE
IF ENOUGH CONVECTIVE DEBRIS IS AROUND. WE TENDED TO FOLLOW THE LOWER
MAV TEMPS HERE.

THU NIGHT...THE COLD FRONT MOVES ACROSS MOST OF THE FORECAST AREA
WITH PERSISTENT SHOWERS AND SCATTERED THUNDERSTORM CONTINUING.  THE
COLD FRONT BEGINS TO LOOK MORE ANAFRONTAL BY DAY BREAK FRI. WE
CONTINUED WITH LIKELY POPS HERE.

FRIDAY INTO FRIDAY NIGHT...THE GFS AND NAM SHOW A WAVE MOVING ALONG
THE STALLED COLD FRONT. THE GFS IS FASTER THAN THE NAM. A BATCH OF
RAIN MOVES IN LATE IN THE DAY AND CONTINUES OVERNIGHT. THE REGION
GETS UNDER THE INFLUENCE OF THE RIGHT REAR QUAD OF THE H300 JET WITH
DECENT DIVERGENCE.  A GOOD H850-700 DEFORMATION ZONE SETS UP FROM
ALY SOUTH AND EAST. THE HEAVIEST RAIN AT THIS TIME APPEARS IT WOULD
FALL FRIDAY NIGHT INTO SATURDAY MORNING...ESPECIALLY OVER THE
HOUSATONIC BASIN. THERE IS PLENTY OF TIME TO ASSESS THIS...AND WE
WILL NOT PUT UP ANY FLAGS AT THIS TIME. LIKELY AND CATEGORICAL POPS
WERE USED ON BOTH DAYS.

ON SATURDAY...THE UPPER LEVEL TROUGH CLOSES OFF OVER NEW ENGLAND
WITH THE COASTAL WAVE REACHING THE GULF OF MAINE BY MID DAY. WRAP
AROUND SHOWERS WILL PERSIST OVER MOST OF THE FORECAST AREA.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
THE LONG TERM PORTION OF THE FORECAST STARTS OUT A LITTLE UNSETTLED
AND THEN A TRANQUIL PERIOD SETTLES IN. THE 00Z...06Z AND 12Z
GFS...06Z DGEX...00Z ECMWF...00Z CAN GLOBAL GEM...06Z ENSEMBLES AND
THE HPC GRAPHICS WERE VIEWED FOR THE EXTENDED PORTION OF THE
FORECAST. THE UPPER LEVEL LOW BRIEFLY CUTS OFF OVER ERN NY AND NEW
ENGLAND ON SAT WITH A SFC COASTAL LOW NEAR LONG ISLAND. RESIDUAL
SHOWERS WILL PERSIST... ESPECIALLY FOR THE ERN HALF OF THE FCST AREA
INTO SAT NIGHT.  THE 06Z DGEX KEEPS THE WET WEATHER INTO
SUNDAY...BUT THIS IS AN OUTLIER COMPARED TO THE OTHER GUIDANCE AND
06Z ENSEMBLES.  ON SUN...THE REGION GETS INTO NORTHWESTERLY FLOW
ALOFT WITH THE COASTAL LOW MOVING NORTHEAST INTO THE CANADIAN
MARITIMES.  A WEAK SURFACE HIGH BUILDS IN FROM SOUTHEASTERN ONTARIO
OVER NY AND WRN NEW ENGLAND ON SUNDAY.  THE HIGH...REMAINS OVER THE
FCST AREA THRU TUESDAY WITH SEASONABLY COOL AND DRY WEATHER.  H850
TEMPS FALL TO +8-+10C BY SUN.  TEMPS AT THAT LEVEL MODERATE TO
+12-+14C BY THE MIDDLE OF THE WEEK.  THE NEXT THREAT OF WET WEATHER
WOULD COME ON WEDNESDAY.  A WAVE OF LOW PRESSURE MOVING THROUGH THE
OHIO VALLEY AND THE LOWER GREAT LAKES REGION PUSHES A WARM FRONT
CLOSER THE NORTHEAST...WITH THE THREAT OF SOME SHOWERS.
OVERALL...TEMPS WILL BE NEAR NORMAL TO SLIGHTLY ABOVE NORMAL WITH
PCPN BELOW NORMAL.

&&

.AVIATION......THUS FAR...ONLY SCATTERED SHOWERS AND STORMS CONFINED
TO ADIRONDACK PARK...NORTH OF KGFL. SOME HAZE BEING REPORTED. EXPECT
MAINLY VFR CONDITIONS FOR THE REST OF THE TODAY...WITH ONLY AN
ISOLATED SHOWER POSSIBLE AND MOST (IF ANY) THUNDERSTORMS STAYING
WELL TO THE WEST. BETTER CHANCE FOR SHOWERS AND ANY THUNDER WILL BE
AROUND 00Z WHEN THE NEXT DISTURBANCE RIPPLES ON THROUGH.
TONIGHT...CONDITIONS WILL DETERIORATE BACK TO MVFR/IFR AS WE EXPECT
MORE CEILINGS AND FOG.

&&

.HYDROLOGY...NOT MUCH NEW RAINFALL THUS FAR TODAY...WITH THE ONLY
ACTIVITY SKIMMING THE EXTREME NORTHERN PORTIONS OF OUR HSA. EXPECT
WIDELY SCATTERED TO SCATTERED SHOWERS AND STORMS TONIGHT. THE K
INDEX LOOKS TO BE AROUND 20...NOT REALLY FAVORABLE FOR FLASH FLOOD.

AS A SLOW MOVING COLD FRONT BEGINS TO PRESS SOUTH FROM CANADA...MORE
ORGANIZED CONVECTION IS LIKELY COME THURSDAY. THESE COULD PRODUCE
MORE SUBSTANTIAL RAINFALL...PERHAPS PRODUCING SOME LOCALIZED
FLOODING. 12-HR FFG VALUES ARE GENERALLY IN THE 2 AND 3 INCH
RANGE.

THE AFOREMENTIONED FRONT LOOKS TO STALL RIGHT ON TOP...OR JUST TO
THE SOUTH OF OUR AREA THURSDAY NIGHT INTO EARLY SATURDAY. A SLOW
MOVING WAVE IS FORECAST TO EVOLVE INTO A RATHER UNSEASONABLY DEEP
SURFACE LOW PRESSURE...TRACKING ALONG THE EASTERN SEABOARD. THIS
STORM COULD PRODUCE A SOAKING RAINFALL. IT IS STILL TOO EARLY TO
DETERMINE WHERE THE HEAVIEST RAIN WOULD FALL WITH THIS UPCOMING
SCENARIO...SO FOR NOW HAVE DECIDED NOT TO ISSUE AN ESF OR A FFA JUST
YET.
