AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
310 PM EDT WED JUL 1 2009
.SYNOPSIS...
A STRONG UPPER LEVEL LOW NEAR THE EASTERN GREAT LAKES
REGION WILL KEEP THE WEATHER UNSETTLED TODAY THROUGH FRIDAY. THIS
SLOW MOVING CUTOFF LOW WILL PRODUCE SHOWERS AND THUNDERSTORMS OVER
THE NEXT FEW DAYS...AS DISTURBANCES ROTATE AROUND THE UPPER LOW.
THE SHOWERS AND THUNDERSTORMS TODAY THROUGH TONIGHT WILL PRODUCE
VERY HEAVY RAINFALL ACROSS PORTIONS OF THE FORECAST AREA.
&&
.NEAR TERM /THROUGH THURSDAY NIGHT/...
UPDATE TO INCLUDE SEVERE THUNDERSTORM WATCH NUMBER 536 WHICH
IS IN EFFECT UNTIL 9 PM THIS EVENING...FOR LARGE HAIL AND
DAMAGING WINDS.
THE FOG/STRATUS WHICH COVERED THE REGION TOOK ITS TIME BURNING
OFF IN THE HUDSON VALLEY...BUT NOW THAT IT HAS DONE SO THE SUN
WAS DECREASING STABILITY AND CONVECTION WAS FIRING UP ACROSS THE
REGION WEST OF THE HUDSON RIVER. AT THE SAME TIME A VERY ACTIVE
AREA OF CONVECTION WAS OVER NEW ENGLAND MOVING NORTH. DID SOME
MINOR ADJUSTMENTS FOR OUR HIGH TEMPERATURES BASED ON LATEST
OBS. HAVE ONLY MADE MINOR ADJUSTMENTS TO POPS FROM THE PREVIOUS
FORECAST. HAVE GONE WITH CATEGORICAL POPS FOR THIS AFTERNOON...
LIKELY FOR THIS EVENING AND OVERNIGHT INTO THURSDAY MORNING AND
THEN CATEGORICAL FOR THURSDAY AFTERNOON. THE STORM PREDICTION
CENTER HAS SOUTHEASTERN NEW YORK IN THE SLIGHT RISK AREA FOR
BOTH TODAY AND THURSDAY. HAVE KEPT ENHANCED WORDING FOR HEAVY
RAIN...GUSTY WINDS...AND SMALL HAIL THROUGH EARLY THURSDAY
EVENING. BOTH THE GFS AND NAM HAVE CAPES 1000 TO 2000 J/KG
THIS AFTERNOON AND THURSDAY AFTERNOON. PWAT VALUES FROM THE
12Z SOUNDINGS WERE 1.0 TO 1.4 INCHES. STEERING WINDS WERE
AROUND 30 KTS FROM THE SOUTH...WHICH WILL RESULT IN WIDESPREAD
TRAINING OF CELLS. THIS PATTERN IS EXPECTED TO PERSIST THROUGH
THURSDAY...THUS WE HAVE EXTENDED THE FLASH FLOOD WATCH UNTIL
02Z FRIDAY OR 10PM THURSDAY. BY THEN WE EXPECT MOST OF THE
HEAVY CONVECTION TO DIMINISH SOMEWHAT. LIFTED INDEXES MINUS
MINUS 2 TO MINUS 6 BOTH THIS AFTERNOON AND AGAIN THURSDAY
AFTERNOON. FOR THE LOW TONIGHT AND THURSDAY NIGHT...AND THE
HIGH THURSDAY...HAVE GONE WITH A BLEND OF THE MET/MOS AND
THE MAV/MOS GUIDANCE...AND PRIMARILY USED THE NAM-12 FOR THE
WINDS...WITH SOME ENHANCEMENT FOR WIND GUSTS DURING THE AFTER
NOON HOURS.
THE CUTOFF LOW AT 500 HPA IS FORECAST TO MOVE VERY LITTLE DURING
THIS PERIOD...WITH IMPULSES ROTATING AROUND IT.
&&
.SHORT TERM /FRIDAY THROUGH MONDAY/...LOW PRESSURE WILL CONTINUE TO
BE ANCHORED ACROSS THE NORTHEAST ON FRIDAY. THIS WILL KEEP THE
WEATHER UNSETTLED FOR FRIDAY THROUGH EARLY SATURDAY AM. WILL KEEP
THE THREAT OF SHOWERS AND THUNDERSTORMS IN THE FORECAST ON FRIDAY. ON
SATURDAY...THE LOW PRESSURE SYSTEM WILL MOVE EASTWARD AND IT LOOKS
LIKE THE PRECIP SHOULD PHASE OUT FOR LATE SATURDAY AND THE LATTER
HALF OF THE WEEKEND. HAVE LEANED TOWARDS THE GFS SOLUTION FOR THE
FRIDAY THROUGH MONDAY PERIOD. BY SUNDAY AND MONDAY...WILL DROP
POPS TO SLIGHT CHANCE AT MOST AS THE GFS MOVES THE LOW PRESSURE
SYSTEM OFF THE EAST COAST. &&
.LONG TERM /MONDAY THROUGH WEDNESDAY/...
WITH THE ONGOING CONVECTION HAVE OPTED TO POPULATE THE EXTENDED
GRIDS WITH HPC GUIDANCE WITH ONLY A FEW CHANGES MOSTLY TO BLEND
BETTER WITH ADJOINING WFOS. FRONTAL SYSTEM STALLS OVER THE DEEP
SOUTH WITH A WEAK HIGH MOVING IN FROM THE WEST. A WEAK IMPULSE
DROPS SOUTH OUT OF CANADA TUESDAY NIGHT AND A WEAK LOW
DEVELOPS JUST NORTH OF THE BORDER EARLY WEDNESDAY. HAVE MOSTLY
GONE WITH SLIGHT CHANCE OR LOW CHANCE POPS.
&&
.AVIATION /17Z WEDNESDAY THROUGH SUNDAY/...
THE FOG WILL GRADUALLY LIFT BTWN 12Z AND 13Z WITH MVFR CONDITIONS
GIVING WAY TO VFR CONDITIONS BY 16Z. THE VFR CONDITIONS WILL BE
SHORT LIVED AS ANY BREAKS IN THE CLOUD COVER WILL ALLOW HEATING OF
THE VERY UNSTABLE AIR ASSOCIATED WITH THE UPPER LOW WHICH WILL
PRODUCE MORE SHOWERS AND THUNDERSTORMS AFTER 18Z. HAVE PLACED A CB
CLOUD GROUP IN THE TAFS STARTING AT 16Z. FOR TONIGHT EXPECT DENSE
FOG TO DEVELOP AGAIN MAINLY DURING THE LATE EVENING HOURS. WHILE
NOT CERTAIN HOW LONG THE SHOWERS AND THUNDERSTORMS WILL LINGER
THIS EVENING...HAVE PLACED A VCSH IN THE TAFS FROM LATE EVENING ON
AS WELL.
OUTLOOK...
THU-SUN...VFR/MVFR...SCATTERED TO NUMEROUS MAINLY AFTN SHRA/TSRA
AND SOME EARLY MORNING BR/FG.
&&
.FIRE WEATHER...
A SLOW MOVING UPPER LOW WILL KEEP THE THREAT OF SHOWERS AND
THUNDERSTORMS ACROSS THE REGION THE NEXT FEW DAYS. THE SHOWERS AND
THUNDERSTORMS WILL TEND TO BE MORE NUMEROUS DURING THE AFTERNOON AND
EARLY EVENING HOURS.
EXPECT THE RH VALUES TO REMAIN RELATIVELY HIGH IN THE MOIST AIR
MASS TODAY WITH MINIMUM VALUES OF 65 TO 80 PERCENT. RH VALUES WILL
RECOVER TO NEAR 100 PERCENT TOMORROW NIGHT...FALL BACK TO 70 TO 90
PERCENT THURSDAY...THEN INCREASE TO AROUND 100 PERCENT THURSDAY
NIGHT. FOG DRIP AND/OR DEW WILL BE LIKELY DURING THE EARLY MORNING
HOURS.
THE WINDS WILL BE FROM THE SOUTH OR SOUTHEAST TODAY AT AROUND 10
MPH...THEN DIMINISH TONIGHT...THEN TURN SOUTH/SOUTHWEST AT 5 TO 15
MPH ON THURSDAY.
&&
.HYDROLOGY...
A FLASH FLOOD WATCH WAS ISSUED FOR THE ENTIRE FORECAST AREA
UNTIL 10 PM THURSDAY BASED ON WET ANTECEDENT CONDITIONS FROM
YESTERDAYS CONVECTION...HIGH CAPE VALUES...HIGH PWATS...AND
THE POSSIBILITY OF TRAINING SHOWERS AND THUNDERSTORMS ONCE
AGAIN TODAY THROUGH THURSDAY EVENING.
MANY LOCATIONS BASED ON GROUND TRUTH AND THE STORM TOTAL
PRECIPITATION PRODUCT HAD 1-2 INCHES OF RAINFALL...WITH SOME
LOCATIONS GETTING OVER 3 INCHES FROM THE HUDSON RIVER VALLEY...
THE LAKE GEORGE REGION EAST NORTHEAST INTO SOUTHERN VERMONT.
ANOTHER PCPN MAXIMUM OF 1-3 INCHES OCCURRED IN THE CENTRAL
MOHAWK VALLEY. SHOWERS AND THUNDERSTORM WILL TEND TO MOVE S/SW TO
THE N/NE TODAY...WITH PRECIPITABLE WATER VALUES IN THE 1-1.5 RANGE
DOWNPOURS OF AN INCH OR SO IN LESS THAN AN HOUR MAY OCCUR. THE
THREAT OF TRAINING THUNDERSTORMS...AND OROGRAPHIC ENHANCEMENT OVER
THE HIGHER TERRAIN IN THE S/SW FLOW WILL ALSO INCREASE THE POTENTIAL
FLASH FLOOD THREAT. THE 1-HR ZONE FFG VALUES ARE BETWEEN 1 AND 2.5
INCHES ACROSS THE HSA. WE ARE EXPECTING AN ADDITIONAL 1-2 INCHES OF
RAINFALL WITH LOCALLY HIGHER AMOUNTS IN EXCESS OF 3 INCHES BY
SUNRISE THURSDAY AND THE POTENTIAL DOES EXIST FOR SOME FLASH
FLOODING.
ANOTHER BOUT OF RAINFALL WILL BE POSSIBLE THU WITH ANOTHER UPPER
LEVEL IMPULSE...AND SFC WAVE ROTATING AROUND THE UPPER LOW. THIS
COULD BRING AN ADDITIONAL INCH OR SO OF RAINFALL...SO WE HAVE
EXTENDED THE WATCH.
MAIN STEM RIVERS HAVE NOT BEEN AFFECTED THAT MUCH SO FAR SINCE
THE HEAVY RAINS HAVE BEEN OVER RELATIVELY SMALL AREAS. HOWEVER
HEAVY RAINFALL OVER A PARTICULAR RIVER BASIN COULD BRING THAT
RIVER TO NEAR OR OVER FLOOD.
