AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
810 PM EDT SAT MAY 14 2011

.SYNOPSIS...
A LOW PRESSURE SYSTEM OVER THE OHIO VALLEY WILL MOVE TO THE
MID-ATLANTIC STATES BY SUNDAY NIGHT AS A FRONTAL BOUNDARY SAGS SOUTH
ACROSS LAKE ONTARIO INTO WESTERN NEW YORK. THIS WILL RESULT IN
CONTINUED WET WEATHER ACROSS WESTERN NEW YORK WITH A CHANCE OF
THUNDERSTORMS THIS AFTERNOON ACROSS THE SOUTHERN TIER. EXPECT
TEMPERATURES TO COOL DOWN STARTING TONIGHT AS BREEZY NORTHEAST FLOW
DEVELOPS JUST BEHIND THE FRONTAL BOUNDARY.

&&

.NEAR TERM /THROUGH SUNDAY/...
AT 23Z FRONTAL BOUNDARY REMAINS STALLED ACROSS OUR REGION FROM THE
NORTH COUNTRY THROUGH WESTERN NEW YORK...AND TO THE PARENT LOW OVER
THE OHIO VALLEY. NORTH OF THIS BOUNDARY WINDS ARE NORTHEAST WITH A
LOW LEVEL CONVERGENT STRATIFORM RAIN FALLING ACROSS NORTHERN LAKE
ONTARIO AND THE NORTH COUNTRY. AS THE NORTH COUNTRY REMAINS IN
THE INFLUENCES OF THE RIGHT ENTRANCE REGION OF A 120 KT JET AT 250
HPA...THAT WILL ONLY SLOWLY PUSH EASTWARD...AND COMBINED WITH THE
STALLED FRONTAL BOUNDARY EXPECT THIS STRATIFORM RAIN TO LINGER
THROUGH MUCH OF THE NIGHT AND INTO SUNDAY MORNING ACROSS THE NORTH
COUNTRY.

SOUTH OF THIS BOUNDARY MORE CELLULAR ACTIVITY WITH LITTLE THUNDER
ACTIVITY THIS EVENING. AS THE AIRMASS BECOMES MORE STABLE BOTH AT THE SFC
AND ALOFT EXPECT ANY THUNDER ACTIVITY TO WANE LATER THIS EVENING.
WILL LEAVE THUNDER IN THE GRIDS ACROSS THE SOUTHERN TIER AS
CONVECTION BLOSSOMING ON THE DIFFERENTIAL HEATING BOUNDARY ON THE
PERIPHERY OF A CLOUD CLEARING ACROSS EASTERN OHIO AND NORTHWESTERN
PA MAY PUSH NORTHEASTWARD ACROSS THE STATE LINE THIS EVENING. AS THE
SUN SETS AND THIS DIFFERENTIAL HEATING BECOMES LESS OF AN IMPACT
WILL DROP THUNDER FROM THE GRIDS LATER THIS EVENING. WILL ALSO CARRY
THUNDER ACROSS THE NORTHERN GENESEE VALLEY AS CELLS ARE BLOSSOMING
ALONG THE BOUNDARY AT 00Z THIS EVENING.

HAVE ALSO ADDED FOG INTO THE FORECAST AS DEWPOINT DEPRESSION BECOMES
LESS THROUGH THE EVENING HOURS...WINDS DIMINISH MORE AND A SATURATED
GROUND REMAINS. EXPECT LOW CLOUDS AND FOG ACROSS THE SOUTHERN
TIER...AND HILLS OF SOUTHERN ERIE...WYOMING AND SOUTHERN GENESEE
VALLEY TONIGHT. NORTH OF THIS STALLED BOUNDARY A NORTHEAST WIND
OVER THE YET STILL COOL LAKE WATERS WILL BRING FOG ALONG THE
SOUTHERN SHORELINE OF LAKE ONTARIO...ESPECIALLY NORTH OF THE
ESCARPMENT. ELSEWHERE JUST EXPECT PATCHY FOG TO FORM.

TEMPERATURES TONIGHT WILL SLOWLY FALL BACK INTO THE 50S ACROSS THE
REGION. WINDS WILL PICK UP LATER IN THE NIGHT ACROSS THE NORTH
COUNTRY AS THIS SFC LOW CONSOLIDATES AND FRONTAL BOUNDARY BEGINS TO
PIVOT SOUTHWARD.

THE AFOREMENTIONED FRONTAL BOUNDARY STALLS OUT AND PIVOTS ACROSS
WESTERN NEW YORK ON SUNDAY AS THE UPPER AND SURFACE LOW TO OUR
SOUTH MOVES TO THE MID-ATLANTIC STATES...RESULTING IN CONTINUED
WIDESPREAD RAINFALL WITH UP TO ANOTHER INCH OR SO POSSIBLE ACROSS
THE REGION. LOCALLY HIGHER AMOUNTS OF RAIN MAY BE POSSIBLE
DEPENDING ON THE EXACT LOCATION OF THE BOUNDARY. IN ADDITION LOOK
FOR COLDER TEMPERATURES SUNDAY AS COOL AIR FILTERS IN ACROSS THE
LAKES ALONG THE FRONTAL BOUNDARY WITH HIGHS GENERALLY IN THE 50S.
IN ADDITION...EXPECT GUSTY NORTHEAST WINDS TO DEVELOP BEHIND THE
BOUNDARY WITH GUSTS OF 20 TO 25 MPH POSSIBLE NEAR THE
LAKES...MAKING FOR A CHILLY AND BLUSTERY SUNDAY.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
THIS PERIOD WILL BEGIN WITH A CLOSED UPPER LOW OVER THE OHIO VALLEY
AND AN ASSOCIATED SURFACE LOW ALONG THE MARYLAND-PENNSYLVANIA
BORDER...WITH A RATHER WELL-DEFINED DEFORMATION ZONE DRAPED FROM
SOUTHERN LOWER MICHIGAN...EAST-NORTHEAST ACROSS NEW YORK STATE TO
NEW ENGLAND.

OVER THE COURSE OF SUNDAY NIGHT...THE CLOSED UPPER LOW WILL
TEMPORARILY OPEN UP INTO AN ELONGATED NORTH-SOUTH UPPER TROUGH AS A
RATHER POTENT NORTHERN STREAM SHORTWAVE DROPS FROM NORTHERN ONTARIO
INTO THE UPPER GREAT LAKES. AT THE LOWER LEVELS...THIS WILL LEAD TO
A CORRESPONDING NORTH-SOUTH ELONGATION OF THE SURFACE LOW...WITH THE
AFOREMENTIONED DEFORMATION ZONE PIVOTING NORTHWESTWARD AND BECOMING
FURTHER STRETCHED OUT. AS THIS OCCURS...THE BEST LARGE-SCALE LIFT
WILL SLIDE OFF TO OUR NORTHEAST...WITH MID AND UPPER LEVEL MOISTURE
OVER OUR AREA ALSO THINNING OUT A BIT.

ALL OF THIS WILL ADD UP TO SOME SEMBLANCE OF A DOWNWARD TREND IN
PRECIP CHANCES AS THE NIGHT PROGRESSES...THOUGH CONTINUED WEAK LIFT
ASSOCIATED WITH BOTH THE DEFORMATION ZONE AND BROAD-SCALE UPPER
LEVEL DIFFLUENCE SHOULD STILL MAINTAIN AT LEAST A LIKELIHOOD OF SOME
LIGHT PRECIP LATER ON IN THE NIGHT. ACCORDINGLY...HAVE STARTED OUT
SUNDAY EVENING WITH A MIX OF LIKELY TO CATEGORICAL POPS...WHICH THEN
GRADUALLY DROP OFF TO LOW LIKELY DURING THE COURSE OF THE NIGHT.

ON MONDAY...THE DEFORMATION ZONE WILL REMAIN PARKED DIRECTLY OVER
OUR AREA AS THE LOCATION OF THE LOWER AND UPPER LEVEL TROUGHS WILL
CHANGE LITTLE. WEAK TO MODEST LIFT WITHIN THIS DEFORMATION ZONE WILL
COMBINE WITH DEEP ENOUGH MOISTURE TO PRODUCE A CONTINUED LIKELIHOOD
OF PERIODIC LIGHT RAIN...THEREFORE HAVE CONTINUED WITH LIKELY POPS
ON MONDAY.

THEN DURING THE REMAINDER OF THE PERIOD...THE UPPER TROUGH WILL ONCE
AGAIN EVOLVE INTO A CLOSED OHIO VALLEY LOW AS ITS MAIN EMBEDDED
SHORTWAVE DROPS INTO THE OHIO VALLEY AND BECOMES CUT OFF FROM THE
NORTHERN BRANCH OF THE WESTERLIES. AS THIS TRANSFORMATION OCCURS...
THE SURFACE LOW WILL CONSOLIDATE FURTHER SOUTH OVER VIRGINIA AND
NORTH CAROLINA...ALLOWING A DEEPENING EASTERLY TO SOUTHEASTERLY FLOW
OF MILDER AND INCREASINGLY MOIST ATLANTIC AIR TO SPREAD BACK ACROSS
OUR AREA. THIS WILL ESPECIALLY BE THE CASE DURING TUESDAY AND
TUESDAY EVENING...WHEN WARM ADVECTION ALOFT WILL BE AT ITS
STRONGEST.

WITH THE LINGERING DEFORMATION ZONE FORCING QUICKLY GIVING WAY TO
INCREASING WARM AIR ADVECTION AND A MORE STRONGLY DIFFLUENT FLOW
ALOFT DURING THE LATTER HALF OF THE PERIOD...THERE WILL BE LITTLE
CHANCE FOR MUCH OF A DRY PERIOD BETWEEN MONDAY NIGHT AND TUESDAY
NIGHT...ESPECIALLY LATER ON IN THE PERIOD WHEN LARGE-SCALE FORCING
WILL BECOME STRONGER DUE TO THE STRENGTHENING WARM ADVECTION AND
UPPER DIFFLUENCE...AND AN APPROACHING SOUTHEASTERLY LOW-LEVEL JET.
FOR THIS REASON...SEE NO REASON TO STRAY FROM CONTINUED LIKELY POPS
THROUGHOUT THIS TIME FRAME. HAVE ALSO INTRODUCED THE CHANCE OF
THUNDER FOR TUESDAY AFTERNOON AND NIGHT...AS THE INCREASINGLY WARMER
AIR ALOFT WILL ALSO LIKELY LEAD TO THE DEVELOPMENT OF SOME ELEVATED
INSTABILITY.

WITH REGARD TO POTENTIAL RAINFALL AMOUNTS...AT THIS POINT A ROUGH
MODEL/HPC CONSENSUS SUGGESTS THAT THESE WILL RANGE IN THE ONE THIRD
TO THREE QUARTERS OF AN INCH RANGE BETWEEN SUNDAY NIGHT AND
MONDAY...FOLLOWED BY ANOTHER QUARTER TO A HALF INCH BETWEEN MONDAY
NIGHT AND TUESDAY...WITH THE POTENTIAL FOR EVEN MORE TUESDAY NIGHT.
NEEDLESS TO SAY...THIS WILL LEAD TO ADDITIONAL POTENTIAL FLOODING
CONCERNS...WHICH WE WILL CONTINUE TO HIGHLIGHT IN THE HWO.

WITH RESPECT TO TEMPERATURES...WITH OUR AREA ON THE NORTH SIDE OF
THE SURFACE AND UPPER LOWS...OUR TEMPERATURES WILL REMAIN BELOW
NORMAL THROUGH THE PERIOD. THIS WILL BE ESPECIALLY BE THE CASE
DURING MONDAY...WHEN THE COMBINATION OF THE RAIN...PLENTIFUL CLOUD
COVER...AND A CHILLY NORTHEASTERLY FLOW WILL KEEP TEMPERATURES FROM
GETTING MUCH ABOVE THE LOWER 50S.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
IN A NUTSHELL...THE WEATHER WILL REMAIN UNSETTLED DURING THIS
PERIOD...WITH NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES AND
RAINFALL CHANCES CONTINUING.

DURING THE FIRST HALF OF THIS PERIOD...THE PERSISTENT CLOSED UPPER
LOW WILL LINGER OVER THE OHIO VALLEY. WITH THIS FEATURE REMAINING
SITUATED TO OUR SOUTHWEST...A SOUTHEASTERLY FLOW OF ATLANTIC
MOISTURE WILL CONTINUE ACROSS NEW YORK STATE...WITH PERIODIC SPOKES
OF ENERGY ROTATING AROUND THE LOW LIFTING THIS MOISTURE AND
MAINTAINING A DECENT POTENTIAL FOR MORE SHOWERS RIGHT THROUGH
THURSDAY. THE OVERALL PATTERN AND LATEST GFS ARE BOTH SUGGESTIVE OF
ENOUGH INSTABILITY DEVELOPING TO SUPPORT THE POSSIBILITY OF SOME
THUNDERSTORMS BOTH WEDNESDAY AND THURSDAY AFTERNOONS...SO HAVE ADDED
A MENTION TO THESE TO THE FORECAST.

LATER ON IN THE PERIOD...THE MEDIUM RANGE MODELS GENERALLY INDICATE
THAT THE CLOSED UPPER LOW WILL WEAKEN AND EVENTUALLY DRIFT OFF THE
ATLANTIC COAST BY THE END OF THE WEEK...THOUGH THE PACE OF THIS
WEAKENING AND THE EVENTUAL TRACK OF THE DEPARTING LOW REMAIN
SOMEWHAT UNCERTAIN. WITH THIS IN MIND...WILL UNFORTUNATELY NEED TO
MAINTAIN SHOWER AND DAYTIME THUNDER CHANCES RIGHT THROUGH THE END OF
THE WEEK...THOUGH THERE WILL BE A GRADUAL DIMINISHING TREND WITH
TIME GIVEN THE OVERALL WEAKENING TREND OF THE LOW AND THE
ENTRAINMENT OF INCREASINGLY DRIER AIR INTO ITS CIRCULATION.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
SHOWER ACTIVITY WILL CONTINUE THROUGH THE EVENING HOURS...THOUGH
WITH AIRMASS BECOMING MORE STABLE...WILL CARRY JUST A CB FOR THE
SOUTHERN TIER AND GENESEE VALLEY TO START THE 00Z TAF CYCLE.

CONDITIONS WILL DETERIORATE THIS EVENING TO IFR...AND LOCAL LIFR AS
ABUNDANT LOW LEVEL MOISTURE REMAINS ACROSS THE REGION ALONG A
STALLED FRONTAL BOUNDARY. EXPECT CIGS TO DROP INTO THE LIFR
CATEGORY AT BOTH THE KJHW AND KIAG TERMINALS THOUGH VISIBILITIES
WILL REMAIN IFR MUCH OF THE TIME. ABUNDANT MOISTURE IN THE LOW
LEVELS WILL LOWER CIGS FOR KJHW THROUGH THE NIGHT...AND FOR KIAG
A NORTHEAST WIND ACROSS A YET STILL COOL LAKE WILL LEAD TO AREAS LOW
CIGS AND FOG. ELSEWHERE EXPECT BOTH IFR CIGS AND VSBYS TO LINGER
THROUGH THE NIGHT...AND INTO MUCH OF SUNDAY. KART MAY ACTUALLY
IMPROVE TO MVFR CIGS WITH THE NORTHEAST FLOW...THOUGH WITH RAIN
THROUGH MUCH OF THE TAF CYCLE...VISIBILITIES WILL LIKELY REMAIN IFR.

UNCERTAIN CONFIDENCE FOR HOW FAR INLAND THESE LOW CIGS WILL REACH
LEAD TO LEAVING THE KROC AND KBUF TERMINALS IN IFR CIGS THROUGH THE
NIGHT. A POSSIBLE SOUTHWARD PUSH OF THESE LOW CIGS WILL BE MONITORED
FOR THESE TERMINALS.

SUNDAY RAIN ALONG THE FRONTAL BOUNDARY WILL SLOWLY PUSH SOUTHWARD AS
THE OHIO VALLEY LOW CONSOLIDATES. AS THIS BOUNDARY PUSHES SOUTHWARD
EXPECT WINDS TO INCREASE THROUGH THE AFTERNOON.

OUTLOOK...
SUNDAY NIGHT THROUGH WEDNESDAY...IFR/MVFR WITH RAIN
LIKELY THROUGH WEDNESDAY.
THURSDAY...MVFR WITH SCATTERED SHOWERS.

&&

.MARINE...
WINDS WILL REMAIN LIGHT ACROSS THE LAKES THIS EVENING WITH WAVES
GENERALLY A FOOT OR LESS. A MILD NORTHEAST FLOW ACROSS THE YET STILL
COOL LAKE ONTARIO WILL PRODUCE LOCAL AREAS OF FOG OVERNIGHT...WITH
VISIBILITIES DROPPING TO UNDER A HALF A MILE AT TIMES.

SMALL CRAFT ADVISORIES WILL BE ISSUED FROM SUNDAY ONWARDS AS
NORTHEAST FLOW STRENGTHENS TO 15 TO 20 KTS ON A LONG FETCH THAT WILL
ALLOW WAVES TO BUILD TO 4 TO 6 FEET...HIGHEST ACROSS CENTRAL AND
EASTERN LAKE ONTARIO. EXPECT THE NORTHEASTERLY WINDS...AND THE SMALL
CRAFT ADVISORIES TO CONTINUE AT LEAST THROUGH SUNDAY NIGHT.
