AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
636 AM EST SAT NOV 21 2015
.SYNOPSIS...
TODAY WILL BE A MOSTLY DRY DAY WITH SEASONABLY COOL TEMPERATURES. A
STORM SYSTEM WILL MOVE TO OUR WEST...BRINGING GUSTY WINDS
TONIGHT...FOLLOWED BY LOCALIZED LAKE EFFECT SNOW EAST OF THE LAKES
SUNDAY INTO MONDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
HIGH PRESSURE ACROSS THE REGION WILL GRADUALLY SLIDE INTO NEW
ENGLAND TODAY. THIS WILL PROVIDE MAINLY DRY CONDITIONS TODAY. THE
EXCEPTION WILL BE ACROSS THE NIAGARA FRONTIER WHERE AN AREA OF MID-
LEVEL WARM AIR ADVECTION WILL MOVE ACROSS THE LAND BREEZE
CONVERGENCE BOUNDARY ON LAKE ERIE. RADAR SHOWS SOME LIGHT RETURNS
ACROSS THIS AREA...WHICH MAY RESULT IN SOME LIGHT RAIN OR SNOW
SHOWERS THIS MORNING. ELSEWHERE TODAY WILL BE MOSTLY CLOUDY DUE
TO THE WARM AIR ADVECTION CLOUDS...WITH PERHAPS A FEW BREAKS OF
SUNSHINE THIS AFTERNOON WHEN THIS AXIS SHIFTS TO THE NORTH.
TEMPERATURES WILL BE SEASONABLE WITH HIGHS IN THE MID TO UPPER
40S.
THINGS GET MUCH MORE ACTIVE TONIGHT WHEN A STRENGTHENING LOW
PRESSURE SYSTEM IS FORECAST TO TRACK TO OUR WEST...ACROSS LAKE ERIE
THIS EVENING AND THEN INTO SOUTHERN ONTARIO LATER TONIGHT. ALTHOUGH
MODEL GUIDANCE IS IN GOOD AGREEMENT ON THIS...THERE IS UNUSUALLY POOR
MODEL AGREEMENT WITH RESPECT TO THE STRENGTH OF THIS LOW. THE GFS
SIGNIFICANTLY STRONGER WITH THIS SYSTEM (991MB VS. 999MB) THROUGH
DAYBREAK SUNDAY. AS A RESULT THE GFS HAS MUCH STRONGER WIND FIELDS
THAN THE NAM. LOOKING AT OTHER GUIDANCE...IT APPEARS THE BROAD MODEL
CONSENSUS IS BETWEEN THE TWO EXTREMES...SLIGHTLY LEANING TOWARD THE
WEAKER NAM SOLUTION AND MORE IN LINE WITH THE 00Z ECMWF/RGEM.
FOLLOWING THIS...THERE IS AMPLE FORECAST CONFIDENCE TO ISSUE WIND
ADVISORIES FOR THE SOUTHWEST FLOW IMMEDIATELY BEHIND THE COLD OR
OCCLUDED FRONTAL PASSAGE WHICH WILL CROSS THE REGION BETWEEN 11 PM
AND 5 AM TONIGHT FROM SW-NE. 925MB WINDS ARE STRONGEST NEAR THE
LAKESHORES...AND SIMILAR TO A SYSTEM JUST A FEW DAYS AGO THESE WINDS
ALOFT SHOULD MIX FAIRLY WELL GIVEN THE RELATIVELY WARM LAKE WATERS
BENEATH THE COOLER AIR ALOFT. THERE IS ALSO A POTENTIAL FOR GUSTY
DOWNSLOPE WINDS NEAR THE LAKE ERIE SHORELINE THIS EVENING...AND
LATER TONIGHT NORTH OF THE TUG HILL. THE WIND DIRECTION IS LESS THAN
IDEAL...MORE SOUTHERLY THAN SOUTHEAST BY THE TIME THE LLJ REACHES
THE AREA. HOWEVER...THERE STILL IS A WINDOW THIS EVENING WHERE GUSTS
SHOULD RUN 40 TO 50 MPH THIS EVENING SO WILL EXTEND THE WIND
ADVISORY TO CAPTURE THIS IN THESE AREAS. IT IS ALSO WORTH NOTING
THAT THESE HEADLINES MAY NEED TO BE ADJUSTED IF MODEL GUIDANCE DOES
SHIFT TO THE STRONGER GFS SOLUTION OR THE WEAKER NAM SOLUTION.
OUTSIDE OF THE WINDS SHOWERS WILL MOVE ACROSS THE REGION WITH THIS
FRONT AND PASSAGE OF THE SURFACE LOW. QPF IS FAIRLY LIGHT WITH
THIS...WITH THE SOUTHERLY FLOW AHEAD OF THE FRONT LIKELY TO RESULT
IN DOWNSLOPING WHICH WILL HELP EVAPORATE WOULD-BE PRECIPITATION.
BECAUSE OF THIS WILL HEDGE POPS AND KEEP THEM MAINLY IN THE CHANCE
TO LIKELY CATEGORIES WITH THE EXCEPTION OF LOCATIONS WHICH UPSLOPE
IN A SOUTHERLY FLOW LIKE THE TUG HILL SOUTH-FACE.
TEMPERATURES WILL DROP RAPIDLY BEHIND THE FRONT...AND WITH LINGERING
MOISTURE IT WILL NOT TAKE MUCH FOR SOME LAKE EFFECT RAIN OR SNOW
SHOWERS TO DEVELOP. THESE WILL MOSTLY BE EAST OF THE LAKES WITH A
WSW POST-FRONTAL FLOW. THROUGH DAYBREAK SUNDAY...SOME LIGHT
ACCUMULATION OF AN INCH OR TWO IS POSSIBLE EAST OF LAKE ONTARIO
ACROSS HIGHER TERRAIN WHERE UPSLOPING AND COLDER TEMPERATURES WILL
HELP GET THINGS GOING. ELSEWHERE...LINGERING RAIN SHOWERS SHOULD
GRADUALLY TRANSITION TO SNOW SHOWERS AS TEMPERATURES FALL INTO THE
30S LATE TONIGHT.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
THIS TIME PERIOD WILL FEATURE A LIGHT WINTRY MIX TRANSITIONING OVER
TO LAKE EFFECT SNOW ACROSS THE SNOW BELTS AS A TROUGH OF LOW
PRESSURE PASSES ACROSS THE EASTERN GREAT LAKES SUNDAY AND MONDAY.
SUNDAY MORNING THE COLD FRONT WILL BE WELL TO OUR EAST WITH A COLD
WESTERLY FLOW POURING OVER THE EASTERN GREAT LAKES. WINDS WILL STILL
REMAIN STRONG EAST OF LAKE ONTARIO EARLY IN THE DAY SUNDAY AS THE
CORE OF THE LLJ WILL STILL BE IN THE PROCESS OF EXITING THE CWA.
WILL HAVE A WIND ADVISORY FOR EAST OF LAKE ONTARIO THROUGH THE
MORNING HOURS TO ACCOUNT FOR THESE STRONG WIND GUSTS. ALSO THESE
STRONG WINDS...ESPECIALLY EAST OF LAKE ONTARIO WILL MAKE IT HARD FOR
ORGANIZED LAKE BANDS TO FORM. SCATTERED SHOWERS EARLY SUNDAY...WITH
EMBEDDED LAKE EFFECT EAST OF THE LAKES WILL LIKELY STILL BE A MIX OF
SNOW AND RAIN. WARMER AIR STILL ACROSS OUR EASTERN ZONES WILL LIKELY
FAVOR MORE RAIN THAN SNOW AT THE START OF SUNDAY...WHILE FARTHER TO
THE WEST WHERE IT WILL BE SLIGHTLY COLDER...MORE SNOW THAN RAIN WILL
LIKELY BE FALLING. AS THE COLD AIR FRESHENS OVER THE REGION SUNDAY
EXPECT A COMPLETE CHANGE OVER TO SNOW...SAVE FOR RIGHT ALONG THE
LAKESHORES WHERE THE YET WARM LAKES MAY INFLUENCE THE BOUNDARY LAYER
ENOUGH TO MAINTAIN SOME RAIN EVEN LATE INTO THE DAY ON SUNDAY.
BY SUNDAY AFTERNOON AND EVENING THE SYNOPTIC WINDS WILL ALIGN ON A
260 TO 270 FLOW...AND WITH LESS SPEED SHEAR AND INCREASE RESIDENCE
TIME OVER THE LAKE WATERS BANDS OF LAKE EFFECT SNOW WILL BECOME
BETTER DEVELOPED. LAKE PARAMETER BECOME FAVORABLE FOR SNOW WITH
TEMPERATURES AT 850 HPA FALLING TO -10 TO -12C WHICH WILL RAISE THE
LAKE EQUILIBRIUM LEVELS UPWARDS TO 10-15K FEET. IN ADDITION TO THE
INSTABILITY...FAVORABLE FOR THIS LAKE EFFECT SNOW EVENT WILL BE THE
DEEP MOISTURE WITHIN THE SNOW DENDRITIC GROWTH ZONE. WINDS WILL
REMAIN SHIFTING AS THE UPPER LEVEL TROUGH PASSES...WITH THE MOST
CONSTANT WIND DIRECTION LIKELY SUNDAY NIGHT AS THE BASE OF THE
TROUGH PASSES.
OFF LAKE ONTARIO...THE WESTERLY FLOW OVER THE LONG STRETCH OF THE
LAKE SHOULD YIELD AN ORGANIZING BAND OF LAKE EFFECT PRECIPITATION
THROUGH THE DAY SUNDAY...REACHING ITS GREATEST INTENSITY SUNDAY
EVENING AND OVERNIGHT. NORTHWESTERLY FLOW ON THE NORTHERN SHORELINE
OF THE LAKE...COMBINED WITH SOUTHWESTERLY FLOW ON THE SOUTHERN
SHORELINE OF LAKE ONTARIO SHOULD BRING AN AREA OF ENHANCED
CONVERGENT UPLIFT...WITH A BAND OF SNOW YIELDING SNOWFALL RATES OF 2
INCHES OR MORE PER HOUR ON THE TUG HILL SUNDAY EVENING AND
OVERNIGHT. AS THE UPPER LEVEL TROUGH PASSES SUNDAY NIGHT THE BAND OF
SNOW WILL SETTLE SOME SOUTHWARD TOWARD OSWEGO AND FAR SOUTHERN LEWIS
COUNTY.
SUNDAY NIGHT UPSTREAM LAKE CONNECTIONS WILL COME INTO PLAY WITH
WESTERLY FLOW SUPPORTING A LAKE HURON CONNECTION.
MONDAY MORNING BEHIND THE UPPER LEVEL TROUGH WINDS WILL BEGIN TO
BACK SOME...ALLOWING THE BAND OF SNOW TO EDGE NORTHWARD...THOUGH
WITH WARMING ALOFT AND INCREASE WIND SHEAR EXPECT THE BAND OF SNOW
TO WEAKEN THROUGH THE DAY ON MONDAY. WILL CONTINUE THE WATCH EAST OF
LAKE ONTARIO AS THERE STILL REMAINS SOME UNCERTAINTY WITH THE
SHIFTING WINDS AND HOW MUCH UPSTREAM LAKE CONNECTION WILL IMPACT THE
SNOWFALL. THE FOCUS OF THE GREATEST SNOWFALL WILL BE UPON THE
CENTRAL AND SOUTHERN REGIONS OF THE TUG HILL WHERE A FOOT OF SNOW
PLUS COULD FALL...ESPECIALLY IF THE WINDS/BAND OF SNOW REMAINS
LOCKED IN ON ONE LOCATION FOR SEVERAL HOURS SUNDAY NIGHT.
OFF LAKE ERIE...LAKE EFFECT PRECIPITATION WILL LIKELY BE ONGOING AT
THE START OF SUNDAY MORNING. THE BULK OF THE PRECIPITATION WILL BE
FALLING IN THE FORM OF SNOW WITH 850 HPA TEMPERATURES SUNDAY MORNING
ALREADY DOWN TO -10C WITHIN THE COLD AIR ADVECTION. THE WESTERLY
FLOW OVER LAKE ERIE TYPICALLY SUPPORTS MORE BROAD LAKE EFFECT BANDS
OF PRECIPITATION. THERE MAY BE A UPSTREAM CONNECTION TO LAKE HURON
MIDDAY SUNDAY...WITH SUCH CONNECTION ENHANCING THE SNOWFALL RATES
EAST OF LAKE ERIE. WITHOUT SUCH CONNECTION SNOWFALL RATES WILL
GENERALLY BE AN INCH OR LESS PER HOUR EAST OF LAKE ERIE...WITH THE
HIGHER TERRAIN OF SW NYS SLOWLY EDGING THEIR WAY UPWARDS TO 6 TO 12
INCHES OF SNOW. WILL MAINTAIN THE LAKE EFFECT SNOW WATCH HERE AS
WELL AS THE BRIEF PERIOD OF FAVORABLE LAKE EFFECT SNOW CONDITIONS
COMBINED WITH THE SHIFTING WINDS MAY NOT ALLOW FOR SNOW
TO ADD UP TO WARNING CRITERIA SNOWFALL.
AN APPROACHING SHORTWAVE LATER SUNDAY NIGHT WILL BEGIN TO INCREASE
THE WIND SHEAR THROUGH THE BOUNDARY LAYER...WITH BOUNDARY LAYER
WINDS BACKING TO MORE OF A SOUTHWESTERLY DIRECTION. EXPECT THE LAKE
EFFECT SNOW TO SLOWLY EDGE NORTHWARD LATE SUNDAY NIGHT AND INTO
MONDAY...BACK TOWARDS THE BUFFALO METRO AREA. NOT EXPECTING MUCH
ACCUMULATION WITHIN THE METRO AREA AS THE BAND WILL BE WEAKENING.
HOWEVER THERE WILL BE INCREASING CHANCES FOR SOME SYNOPTIC SNOW/LAKE
EFFECT SNOW LATER MONDAY AND MONDAY EVENING WITH SOUTHWESTERLY FLOW
AHEAD OF THE NEARING SHORTWAVE TROUGH. THE COLD AIR WILL REMAIN
ALOFT MAINTAINING SNOW DENDRITIC GROWTH ZONE BETWEEN 7 AND 10K FEET
MONDAY NIGHT. WITH MOISTURE POOLING AHEAD OF THE SHORTWAVE
TROUGH...AND WITHIN THE DENDRITIC GROWTH AREA SNOWFALL WILL
BECOME LIKELY MONDAY NIGHT. THIS SWATH OF SNOW LIKELY ACROSS THE
NORTHERN NIAGARA FRONTIER COULD BRING MINOR ACCUMULATION OF SNOW
TO THE NORTHERN NIAGARA FRONTIER BEFORE THE TROUGH SPREADS THE
SNOW SOUTH AND EASTWARD OVERNIGHT MONDAY NIGHT.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
BEHIND THE DEPARTING TROUGH MONDAY NIGHT... A TROUGH WILL DIG ALONG
THE WEST COAST INTO MID-WEEK BEFORE BECOMING CUT-OFF OVER THE
INTER-MOUNTAIN WEST. THIS WILL ALLOW FOR RISING HEIGHTS AND
SOUTHWESTERLY FLOW ACROSS THE FORECAST AREA TUESDAY LEADING INTO THE
THANKSGIVING HOLIDAY. THERE MAY BE LINGERING LIGHT LAKE EFFECT
ACTIVITY OF RAIN AND SNOW EARLY TUESDAY...OTHERWISE A PERIOD OF DRY
WEATHER IS EXPECTED LEADING INTO THANKSGIVING WITH VERY MILD
TEMPERATURES AND CONTINUED DRY WEATHER THURSDAY AND FRIDAY. THE NEXT
CHANCE OF RAIN WILL WILL COME AS LOW ACROSS THE WEST DEPARTS AND
EVENTUALLY DRAGS A COLD FRONT ACROSS THE REGION BY THE WEEKEND.
&&
.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
HIGH PRESSURE WILL GENERALLY BRING VFR CONDITIONS FOR THE VAST
MAJORITY OF TODAY. SOME LIGHT RAIN OR SNOW SHOWERS ARE POSSIBLE
AT BUF/IAG THIS MORNING WITH BRIEF VBSY/CIG RESTRICTIONS POSSIBLE.
OTHERWISE...THERE IT WILL BE MOSTLY CLOUDY TODAY FROM MID- LEVEL
CLOUDS.
A STRONG FRONT WILL CROSS THE REGION TONIGHT AND BRING A PERIOD OF
GUSTY WINDS AND SHOWERS. THE STRONGEST WINDS WILL LAST A FEW HOURS
FOLLOWING THE FRONTAL PASSAGE WITH GUSTS OF 30-40 KTS. BRIEF AND
FAIRLY LIGHT RAIN SHOWERS ALONG THE FRONT WILL BE FOLLOWED BY LAKE
EFFECT SNOW SHOWERS WHICH SHOULD DEVELOP EAST OF THE LAKES LATE
TONIGHT. THESE WILL MAINLY IMPACT THE JHW WHERE IFR CONDITIONS IN
SNOW ARE LIKELY LATE TONIGHT.
OUTLOOK...
SUNDAY...DIMINISHING WINDS WITH AREAS OF IFR/LIFR IN LAKE
EFFECT SNOW EAST OF THE LAKES...AND MAINLY VFR CONDITIONS
ELSEWHERE.
MONDAY...VFR...EXCEPT MVFR/IFR POSSIBLE EAST OF THE LAKES IN
LINGERING LAKE EFFECT SNOW SHOWERS.
TUESDAY AND WEDNESDAY...VFR.
&&
.MARINE...
HIGH PRESSURE WILL BRIEFLY RIDGE INTO THE LOWER LAKES TODAY WHICH
WILL ALLOW THE LAST OF THE SMALL CRAFT HEADLINES TO BE DROPPED.
AFTER THIS A DEEPENING LOW PRESSURE SYSTEM WILL LIFT ACROSS LAKE
ERIE THIS EVENING AND THEN INTO SOUTHERN ONTARIO LATER TONIGHT. THIS
WILL PUSH A STRONG OCCLUDED/COLD FRONT ACROSS THE WATERS TONIGHT
WHICH WILL RESULT IN A PERIOD OF GALES ON THE LAKES AND PORTIONS OF
THE NIAGARA AND ST LAWRENCE RIVERS. MODEL GUIDANCE DIFFERS ON THE
STRENGTH OF THIS LOW...WITH A POTENTIAL FOR WINDS TO BE STRONGER
DEPENDING ON WHICH MODEL VERIFIES. EITHER WAY...WINDS SHOULD FALL IN
THE GALE CATEGORY.
WINDS WILL GRADUALLY DIMINISH LATE SUNDAY WITH THE DEPARTURE OF THE
LOW. THEN A HIGH PRESSURE RIDGE SHOULD BRING A PERIOD OF RELATIVELY
QUIET CONDITIONS ON THE LAKES EARLY NEXT WEEK.
&&
.TIDES/COASTAL FLOODING...
STRONG SOUTHWESTERLY WINDS WILL DEVELOP BEHIND A COLD/OCCLUDED
FRONT WHICH SHOULD CROSS EASTERN LAKE ERIE BETWEEN 11 PM AND 1 AM
TONIGHT. EXPECT BUFFALO TO RISE TO ABOUT 7 FEET ABOVE LOW WATER
DATUM...WITH THIS FORECAST A FOOT HIGHER THAN LEOFS FORECAST
GUIDANCE. THIS WILL BE COMBINED WITH WAVES WHICH SHOULD BUILD TO
AROUND 12 FEET. THE GREATEST LEVELS ARE LIKELY TO OCCUR A COUPLE
HOURS AFTER THE FRONTAL PASSAGE.
