Special Weather Statement, NWS Albany, NY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
735 PM EDT TUE JUL 31 2012

.SYNOPSIS...
A WEAKENING COLD FRONT WILL APPROACH THE REGION ON WEDNESDAY
BRINGING THE INCREASED THREAT FOR SHOWERS AND THUNDERSTORMS.
WEAK HIGH PRESSURE WILL MOVE IN ON THURSDAY AND PERSIST THROUGH
SATURDAY BRINGING TYPICAL SUMMER WEATHER BUT WITH ONLY SMALL
CHANCES OF AFTERNOON AND EVENING SHOWERS OR THUNDERSTORMS. A
HIGHER CHANCE OF SHOWERS AND THUNDERSTORMS WILL COME BY LATER
SUNDAY AS ANOTHER WEAKENING FRONT APPROACHES THE CAPITOL DISTRICT.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
JUST A MINOR SET OF ADJUSTMENTS TO THE FORECAST AS SHOWERS AND
THUNDERSTORMS HAVE NOT ENTERED THE FORECAST AREA YET...AND MAY
TEND TO DECREASE IN COVERAGE AS THEY TRACK EAST DUE TO SOME
SUBSIDENCE BETWEEN THE AXIS OF CONVECTION AND THE SYSTEM OFF NEW
ENGLAND. WILL CHECK THE 00Z DATA CAREFULLY TO SEE IF WESTERN AREAS
WILL SEE MORE COVERAGE THEN EASTERN AREAS AND WHEN AND WHERE THE
INTENSITY OF THE CONVECTION MAY DIMINISH THROUGH THE EVENING.

SO FOR NOW...JUST SOME ADJUSTMENTS TO SKY COVER AND TIMING OF
SCATTERED SHOWERS AND THUNDERSTORMS BASED ON CURRENT OBSERVATIONS
AND TRENDS. ONCE 00Z DATA ARRIVES...SOME MORE ADJUSTMENTS LATER
THIS EVENING.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
WEAKENING FRONT MOVES INTO OUR REGION ON WEDNESDAY WITH INCREASING
POPS AGAIN...TO 40/50 PERCENT BY AFTERNOON. PRECIPITABLE WATER
VALUES CLIMB TO AROUND 1.75 INCHES ON WEDNESDAY. FLOW IS WEAK SO
THERE MAY BE SOME ISOLATED SHOWERS OR STORMS THAT DROP SOME HEAVY
RAIN.

AT THIS POINT...THUNDERSTORMS DO NOT LOOK LIKELY TO BECOME ORGANIZED
OR SEVERE. MID LEVEL LAPSE RATE DO APPROACH 6.5/KM BUT THE WIND
FIELD LOOKS FAIRLY LIGHT AND THE FORCING NOT TOO STRONG. MLCAPES
LOOK TO BE IN THE 800-1500 J/KG RANGE. THIS COULD CERTAINLY LEAD TO
A FEW CELLS THAT COULD PRODUCE SOME LOCALLY GUSTY WIND OR SMALL
HAIL BUT AGAIN...THIS LOOKS LIKE THE EXCEPTION RATHER THAN THE
RULE.

THIS FRONT WILL TEND TO STALL ALONG THE EASTERN SEABOARD AS IT
WEAKENS MORE. WEAK HIGH PRESSURE WILL BUILD IN BEHIND FOR THURSDAY.
AT THIS POINT...MOST AREAS LOOK DRY WITH MORE CAPPING IN THE MID
ATMOSPHERE LIKELY.

THURSDAY NIGHT LOOKS DRY BUT IT WILL CONTINUE TO BE ON THE MUGGY
SIDE.

OVERALL TEMPERATURES WILL CONTINUE RUN A LITTLE ABOVE NORMAL...ESPECIALLY
THURSDAY.

DEWPOINTS LOOK TO REMAIN MAINLY IN THE 60S THROUGHOUT THE PERIOD
WHICH WILL MAKE IT FEEL SOMEWHAT UNCOMFORTABLE BY THURSDAY.
OVERNIGHT LOWS WILL BE HELD MAINLY TO THE 60S.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
SUMMERY VERY WARM(HOT) WEATHER IS EXPECTED FRIDAY THROUGH SUNDAY
WITH JUST A CHANCE OF A MAINLY AFTERNOON OR EVENING THUNDERSTORM
AS THE EXTENSION OF A BERMUDA HIGH CONTROLS OUR WEATHER. WITH 850
TEMPS IN THE UPPER TEENS, EXPECT HIGH TEMPERATURES EITHER SIDE OF
90.

ANOTHER WEAKENING FRONT IS EXPECTED SOMETIME LATER SUNDAY INTO
EARLY MONDAY AND HAVE INCREASED THE CHANCES OF PRECIP DURING THAT
TIME. MODELS ARE PRETTY LOCKED IN ON THIS SYSTEM WITH GOOD DYNAMIC
SUPPORT FROM THE UPPER LEVELS WILL HAVE TO WATCH FOR POTENTIAL
SEVERE WEATHER AND HEAVY RAINS DEPENDING ON THE TIMING OF THE FRONT.

WEAK HIGH PRESSURE WILL MOVE BACK IN LATER MONDAY INTO TUESDAY
WITH TEMPERATURES NEAR NORMAL.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
VFR CONDITIONS EXPECTED TO CONTINUE THIS EVENING...ALTHOUGH KPSF
IS HOVERING NEAR MVFR...BUT THE CLOUD SHIELD AFFECTING KPSF IS
BUILDING EAST...SO THE CEILING SHOULD BREAK UP BEFORE LOWERING
INTO THE MVFR CATEGORY.

A LINE OF SHOWERS AND THUNDERSTORMS ACROSS THE WESTERN MOHAWK
VALLEY AND APPROACHING THE SCHOHAIRE VALLEY...COULD HOLD TOGETHER
LONG ENOUGH THAT THEY COULD AFFECT THE KALB AND KGFL SITES AFTER
MIDNIGHT. INDICATING VCSH FOR THAT REASON. LINGERING LOW LEVEL
MOISTURE AND LIGHT WINDS COULD PROMOTE FOG AND LOW CLOUDS LIKE THE
PAST 2 MORNINGS. THE LINE OF SHOWERS AND STORMS ADDS A WRINKLE
THOUGH...SO HAVE INDICATED MVFR VISIBILITIES WITH SCATTERED
CLOUDS BELOW 1000 FEET SO ONCE LATER DATA IS ANALYZED...06Z TAFS
CAN INDICATE WHTHER IFR IS EXPECTED EARLY TOMORROW MORNING OR NOT.

WHATEVER LOW CLOUDS OR FOG MAY BE AFFECTING THE SITES SHOULD LIFT
THROUGH 14Z...AND VFR CONDITIONS SHOULD PREVAIL MUCH OF TOMORROW.
SCATTTERED AFTERNOON AHOWERS AND THUNDERSTORMS ARE EXPECTED SO
VCSH INCLUDED EVERYWHERE.

SOUTH TO SOUTHEAST WINDS AT LESS AHN 10 KT SHOULD BECOME LIGHT AND
VARIABLE THIS EVENING. WINDS SHOULD BECOME SOUTH AGAIN AT LESS
THAN 10 KT TOMORROW.

OUTLOOK...
THU...VFR. NO SIG WX.
FRI-SUN...VFR/MVFR...CHC SHRA/TSRA.

&&

.FIRE WEATHER...
A WEAKENING FRONT WILL BRING A GREATER CHANCE OF SHOWERS AND
THUNDERSTORMS ON WEDNESDAY. MAXIMUM RH VALUES WILL RISE TO NEAR
85 TO 95% WEDNESDAY MORNING AND FALL TO AROUND 60% WEDNESDAY
AFTERNOON. WINDS WILL GENERALLY BE SOUTHERLY AT 5 TO 15 MPH.

THURSDAY LOOKS MAINLY DRY...VERY WARM BUT THE HUMIDITY VALUES WILL
BE SOMEWHAT ELEVATED...DROPPING DOWN TO 45-50 PERCENT DURING THE
AFTERNOON.

&&

.HYDROLOGY...
NO SIGNIFICANT HYDRO PROBLEMS ARE EXPECTED.

BETTER CHANCES FOR SHOWERS AND THUNDERSTORMS AS WE HEAD INTO
WEDNESDAY...THANKS TO A SLOW MOVING COLD FRONT. PWAT VALUES LOOK
TO BE AROUND 1.75 INCHES. AVERAGE BASIN RAINFALL LOOKS TO BE
AROUND A QUARTER OF AN INCH SO AT THIS POINT...WE ARE NOT
ANTICIPATING ANY IMPACT ON MAIN RIVERS AND STREAMS. HOWEVER...ANY
THUNDERSTORM IS CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL
EXCEEDING AN INCH IN SPOTS.

MAINLY DRY THURSDAY WITH ANY ISOLATED THUNDERSTORMS TO THE SOUTH OF
ALBANY WITH AGAIN LITTLE OR NO IMPACT ON THE OVERALL ALBANY
WATERSHED.

JUST A CHANCE OF MORE SHOWERS AND THUNDERSTORMS ON
FRIDAY AND SATURDAY...AND THEN MORE SHOWERS AND THUNDERSTORMS
POSSIBLE ON LATER SUNDAY INTO EARLY MONDAY. AT THIS POINT...NO OF
THESE LOOK TO POSE A SIGNIFICANT HYDROLOGICAL THREAT ON AREA.
