AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
144 PM EDT SUN APR 22 2012

.SYNOPSIS...
IT WILL BE COOL AND DAMP TODAY WITH DRIZZLE FALLING ON AREAS SOUTH
OF THE LAKE ONTARIO SHORELINE AND INTO THE SOUTHERN TIER TODAY.
ATTENTION WILL THEN TURN TO A SIGNIFICANT EAST COAST STORM THAT WILL
SPREAD RAIN AND SNOW ACROSS THE REGION SUNDAY NIGHT AND INTO THE
BEGINNING OF NEXT WEEK. LATE SEASON SNOW WILL LIKELY BE FOUND ACROSS
WESTERN NEW YORK AND THE SNOW WILL CRIPPLE PORTIONS OF WESTERN NEW
YORK SUNDAY NIGHT THROUGH TUESDAY...ESPECIALLY THE HIGHER TERRAIN OF
SOUTHWESTERN NEW YORK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AREAS OF VERY LIGHT RAIN OR DRIZZLE COMING IN OFF LAKE ONTARIO
CONTINUING ACROSS FAR WESTERN NEW YORK IN NORTHEAST FLOW.
REGIONAL RADARS HAVE BEEN SHOWING A DIMINISHING TREND AND WOULD
EXPECT THIS TREND TO CONTINUE THROUGH THE AFTERNOON. DENSE CLOUD
COVER AND NORTHEAST FLOW WILL HOLD TEMPERATURES NEARLY STEADY IN
THE UPPER 30S TO LOWER 40S.

WILL MAKE NO CHANGES TO THE HEADLINES WITH THIS UPDATE...CONTINUING
WITH THE WINTER STORM WARNING FOR SOUTHERN ERIE...CHAUTAUQUA AND
CATTARAUGUS AND THE WATCH ELSEWHERE AS OUTLINED.

A SIGNIFICANT EAST COAST STORM IS STILL ON TAP AND THIS SYSTEM IS
EXPECTED TO BRING RAIN...WHILE MIXING WITH AND CHANGING TO A HEAVY
WET SNOW ACROSS PORTIONS OF WESTERN NEW YORK.

FOR LATE AFTERNOON AND OVERNIGHT EXPECT RAIN AT THE ONSET TO REACH
THE INTERIOR SOUTHERN TIER EARLY EVENING...WITH RAIN SPREADING
SOUTHEAST TO NORTHWEST ACROSS THE REGION. IT THEN BECOMES A LITTLE
TRICKY AS WARM AIR FROM THE EAST WILL PUSH WESTWARD WITH THE WARM
CONVEYOR BELT AHEAD OF THE SURFACE LOW. THIS SURGE OF WARM AIR WILL
LIKELY KEEP PRECIPITATION AS ALL RAIN FROM THE NORTHERN FINGER LAKES
EASTWARD AND THROUGH THE NORTH COUNTRY SUNDAY NIGHT. A TIGHT
TRANSITIONAL ZONE WILL BE FOUND FROM ROUGHLY ALONG THE GENESEE
VALLEY WHERE 850 HPA TEMPERATURES WILL DROP TO AROUND -2 TO -4C.
THERE IS STILL UNCERTAINTY AS TO WHERE THIS THERMAL GRADIENT WILL
BE...WITH THE 00Z NAM AND GFS A LITTLE FARTHER WEST WITH THE WARMER
AIR. ACROSS THE WESTERN SOUTHERN TIER 850 HPA TEMPERATURES WILL BE
DROPPING TOWARDS -5C ON ALL MODEL RUNS...AND WITH THE MODELS NOW
CONSISTENT WITH PLACING THE COLDEST AIR OVER THIS REGION WE HAVE
UPGRADED THE WINTER STORM WATCH TO A WARNING.

FOR THE SNOW EXPECT THE RAIN TO CHANGE FIRST TO SNOW ACROSS THE
HIGHER ELEVATION OF THE SOUTHERN TIER AROUND MIDNIGHT AS COLD AIR
BUILDS ON THE NORTHWEST SIDE OF THE DEEPENING SFC LOW. SNOW LEVELS
WILL LOWER THROUGH THE NIGHT WITH RAIN CHANGING TO SNOW IN AREAS
SUCH AS THE NORTHERN NIAGARA FRONTIER BY MORNING. THERE IS STILL
SOME UNCERTAINTY ACROSS LOWER ELEVATIONS FOR SNOW TOTALS...AND HAVE
OPTED TO LEAVE THE WINTER WATCH UP FOR NOW.

BOTH THE NAM AND GFS BRING A BULLS EYE OF STRONG LOW LEVEL LIFT
ACROSS THE SOUTHERN TIER MONDAY MORNING. CONSIDERING THIS LIFT ALONG
WITH DEEP MOISTURE UP THROUGH -10C THE SNOW COULD BECOME HEAVY LATE
SUNDAY NIGHT.

A STRONG 50 TO 55 KNOT LOW LEVEL JET WILL DEVELOP AROUND 925 HPA
OVERNIGHT SUNDAY NIGHT THAT...WITH AN INCREASING SFC PRESSURE
GRADIENT WILL BRING GUSTY WINDS TO THE EASTERN LAKE ONTARIO REGION
AND ALONG THE SOUTHERN SHORELINE OF LAKE ONTARIO LATE. WIND GUSTS UP
TO 40 MPH ARE POSSIBLE LATER SUNDAY NIGHT THROUGH THE SAINT LAWRENCE
VALLEY...AND THEN LATER ON IMMEDIATE PORTIONS OF THE SOUTHERN
SHORELINE OF LAKE ONTARIO.

MODEL QPF WILL RANGE UP TO THREE QUARTER OF AN INCH BY 12Z MONDAY
MORNING WITH THE HEAVIEST ACROSS THE GENESEE VALLEY AND EASTERN LAKE
ONTARIO REGION.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
FORECAST PICTURE IS COMING INTO GREATER CLARITY AS MODELS ARE COMING
INTO TIGHTER AGREEMENT ON THE TRACK OF THE COASTAL LOW THAT WILL BE
PLOWING ACROSS NEW YORK STATE MONDAY. MODEL CONSENSUS IS FOR THE LOW
TO TRACK UP DELAWARE BAY SUNDAY NIGHT TO THE POCONOS BY MONDAY
AFTERNOON...THEN ACROSS CENTRAL LAKE ONTARIO MONDAY NIGHT. WITH THE
LOW SPLITTING THE CWA DIRECTLY IN HALF...PRECIP TYPE WILL VARY
WIDELY ACROSS THE FORECAST AREA WITH THE NIAGARA FRONTIER AND
SOUTHERN TIER SEEING POTENTIALLY SIGNIFICANT ACCUMULATING SNOWFALL
WHILE AREAS EAST OF THE GENESEE VALLEY WILL STAY ALL RAIN.

BY MONDAY MORNING SNOWFALL SHOULD BE ONGOING ACROSS THE WESTERN
SOUTHERN TIER AND MUCH OF THE NIAGARA FRONTIER AS A SOLID
DEFORMATION ZONE MOVES OVER THE AREA. SNOWFALL RATES COULD EXCEED
ONE INCH PER HOUR AT TIMES...PARTICULARLY ACROSS THE WESTERN
SOUTHERN TIER WHERE THE STRONGEST LIFT WILL COINCIDE WITH THE SNOW
GROWTH ZONE ALOFT. THE FORECAST GETS TRICKIER AND THE CONFIDENCE IN
SNOW TOTALS LOWERS THE FARTHER NORTH AND EAST OF BUFFALO ONE GOES AS
THE RAIN/SNOW LINE LOOKS TO SET UP NEAR THE NIAGARA/ORLEANS COUNTY
LINE SOUTH INTO ALLEGANY COUNTY...HOWEVER IT NOW APPEARS THAT THE
BUFFALO METRO AREA SHOULD SEE ACCUMULATING SNOWS AS THE COLD AIR
ALOFT SHOULD REMAIN IN PLACE OVER THE AREA AND TEMPERATURES HOVER IN
THE LOW 30S. THE FORECAST GETS MUDDIER AS ONE MOVES EAST TOWARDS
ROCHESTER AS RAIN SNOW MIX WILL LIKELY CHANGE OVER TO ALL RAIN BY
MONDAY AFTERNOON AS THE LOW CENTER MOVES JUST EAST OF THE GENESEE
VALLEY AND WARM AIR WRAPS INTO THE LOW CENTER...WITH PRECIP LIKELY
CHANGING BACK TO ALL SNOW MONDAY NIGHT AS THE LOW LIFTS NORTH INTO
CANADA AND COLD AIR WRAPS BACK ACROSS THE AREA. EAST OF
ROCHESTER...PRECIP TYPE WILL REMAIN ALL RAIN AS SURFACE TEMPERATURES
WILL REMAIN IN THE 40S IN THE WARM SECTOR OF THE LOW. THE TIGHT
GRADIENT AROUND THIS DEEP SURFACE LOW WILL ALSO LEAD TO GALES ONT HE
LAKES WITH WINDY CONDITIONS INLAND. THE INTERACTION OF THESE WINDS
WITH FALLING SNOW ACROSS FAR WESTERN NEW YORK COULD FURTHER ENHANCE
HAZARDOUS CONDITIONS.

PRECIP WILL REMAIN ONGOING THROUGH MONDAY NIGHT INTO TUESDAY MORNING
AS THE SURFACE LOW TRACKS ACROSS LAKE ONTARIO INTO EASTERN ONTARIO
BEFORE BEING SHUNTED NORTH INTO QUEBEC TUESDAY NIGHT. PRECIP SHOULD
TAPER OFF TO BECOME MORE SHOWERY IN NATURE AS THE SURFACE LOW
BECOMES COMPLETELY OCCLUDED AND WEAKENS. WARM AIR WRAPPING AROUND
THE CORE OF THE SURFACE LOW WILL WORK ITS WAY SOUTH ACROSS THE
NIAGARA FRONTIER AND SOUTHERN TIER...CHANGING LINGERING SNOW BACK
OVER TO RAIN BY TUESDAY AFTERNOON. ACCORDINGLY...HIGHS ON TUESDAY
WILL RUN FROM THE UPPER 30S IN THE SOUTHERN TIER WITH 40S ELSEWHERE.

THINGS WILL FINALLY START TO QUIET DOWN TUESDAY NIGHT AS THE
WEAKENING LOW LIFTS NORTH INTO QUEBEC...HOWEVER LINGERING LAKE
EFFECT SHOWERS WILL BE POSSIBLE UNDER WESTERLY FLOW AS AIR ALOFT
WILL BE JUST COLD ENOUGH...PARTICULARLY EAST OF LAKE ONTARIO WHERE
UPSLOPE FLOW WILL FURTHER INCREASE POSSIBILITY OF SHOWERS..THOUGH
TEMPERATURES SHOULD STAY WARM ENOUGH TO KEEP PRECIP ALL RAIN.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
GFS AND ECMWF REMAIN IN FAIR AGREEMENT FOR MUCH OF THE REST OF THE
WEEK...GFS DRYING THINGS OUT A LITTLE MORE QUICKLY BY THE END OF THE
WEEK. WILL KEEP LOW CHANCE POPS IN THROUGH THURSDAY AFTERNOON AS THE
UPPER TROUGH OVER EASTERN CANADA STREAMS A SERIES OF VORTICITY
MAXIMA ACROSS THE GREAT LAKES REGION AND INTO NEW YORK STATE. HIGH
PRESSURE BUILDS IN ACROSS THE REGION ON FRIDAY AND SATURDAY WITH DRY
BUT COOLER THAN NORMAL CONDITIONS. EACH NIGHT THROUGH THE WEEK WILL
HAVE LOW TEMPERATURES NEAR OR BELOW FREEZING...THE EXCEPTION BEING
THOSE LOCATIONS WITHIN THE MODERATING INFLUENCES OF THE GREAT LAKES.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
WIDESPREAD MVFR CIGS ACROSS THE REGION THIS AFTERNOON WILL
CONTINUE INTO THIS EVENING...WITH A MOIST NORTHEAST FLOW OFF LAKE
ONTARIO. DEEPER MOISTURE WILL PUSH INTO THE REGION FROM THE
SOUTHEAST LATER TONIGHT...WITH RAIN BREAKING OUT FROM SOUTHEAST TO
NORTHWEST AFTER 03Z. CONDITIONS WILL LOWER TO IFR OVERNIGHT AS THE
PRECIPITATION SPREAD OVER THE REGION. THE RAIN WILL CHANGE TO SNOW
ACROSS THE WESTERN AIRFIELDS AFTER 06Z...WITH POSSIBLE LIFR
CONDITIONS DEVELOPING BY 12Z.

NORTH TO NORTHEAST WINDS THROUGH THE PERIOD WILL GRADUALLY INCREASE
IN SPEED AS LOW PRESSURE MOVE UP THE EASTERN SEABOARD. SURFACE
WINDS WILL GUST TO 30 KNOTS AT TIME.

IFR CONDITIONS WILL PREVAIL MONDAY IN SNOW AND RAIN. NORTH TO
NORTHEAST WINDS MAY INCREASE TO OVER 35 KNOTS.

OUTLOOK...
MONDAY NIGHT...IFR/MVFR. RAIN OR SNOW LIKELY.
TUESDAY THROUGH THURSDAY...VFR/MVFR WITH A CHANCE OF SHOWERS.
FRIDAY...VFR.

&&

.MARINE...
A GALE WARNING HAS BEEN ISSUED FOR THE EASTERN TWO THIRDS OF LAKE
ONTARIO FOR JUST PAST MIDNIGHT SUNDAY NIGHT THROUGH LATE MONDAY
AFTERNOON AS NORTHEAST WINDS BUILD AHEAD OF A DEEPENING AREA OF LOW
PRESSURE. AS THIS LOW TRACKS NEAR THE EASTERN END OF THE LAKE LATER
MONDAY EXPECT A QUICK DROP IN WIND SPEEDS. ELSEWHERE ON THE LAKES
HAVE ISSUED A GALE WATCH AS WINDS COULD REACH OR EXCEED 35 KNOTS
LATE SUNDAY NIGHT AND THROUGH THE DAY ON MONDAY.

ON THE RIVERS A TIGHTENING PRESSURE GRADIENT AT THE SURFACE WILL
PRODUCE STRONG NORTHEAST WINDS THAT WILL FUNNEL UP THE SAINT
LAWRENCE VALLEY MONDAY. THIS WILL WARRANT A SCA ON THE RIVER EARLY
MORNING ON MONDAY THROUGH THE AFTERNOON HOURS. A SCA HAS ALSO BEEN
ISSUED ON THE NIAGARA RIVER FOR NORTHERLY WINDS THAT WILL REACH AND
EXCEED 20 KNOTS.

&&
