AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE BUFFALO NY
431 AM EDT SUN APR 5 2009

.SYNOPSIS...
LOW PRESSURE OVER MAINE WILL MOVE OUT ACROSS THE CANADIAN MARITIMES
TODAY...WITH WEAK RIDGING BUILDING ACROSS THE AREA IN ITS WAKE. THIS
WILL RESULT IN ANY LINGERING SNOW SHOWERS ENDING EARLY THIS MORNING
ACROSS THE NORTH COUNTRY...WITH DRY AND FAIR WEATHER THEN EXPECTED
FOR THE REMAINDER OF THE DAY. ANOTHER SIGNIFICANT STORM SYSTEM IS
THEN FORECAST TO MOVE INTO THE AREA TONIGHT AND BRING WIDESPREAD
RAIN THROUGH MONDAY...FOLLOWED BY THE POSSIBILITY OF A SIGNIFICANT
EARLY SPRING SNOWFALL MONDAY NIGHT AND TUESDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
A 990MB LOW OVER EASTERN MAINE EARLY THIS MORNING IS NOW IN THE
PROCESS OF SLOWLY FILLING WHILE RIDGING OVER MICHIGAN AND THE OHIO
VALLEY CONTINUES TO PUSH IN OUR DIRECTION. THIS HAS LEAD TO CLEARING
OVER THE WESTERN COUNTIES...WITH THE CLEARING TREND EXPECTED TO
CONTINUE DURING THE COURSE OF TODAY. THE 11-3.9 IMAGERY SHOWS THIS
PROCESS VERY WELL.

AREAS EAST OF LK ONTARIO WILL LIKELY REMAIN UNDER THE STRATO-CU
DECK INTO THE MID MORNING...BUT AT LEAST THE OUT OF SEASON SNOWS
HAVE DIMINISHED. AS OF 0730Z...THE ONLY SNOW SHOWERS REMAINING WERE
FOUND ON THE HILLS EAST OF THE BLACK RIVER VALLEY. THE NORTH COUNTRY
PICKED UP A GENERAL 1 TO 3 INCHES OF SNOW SINCE MIDNIGHT FRIDAY
NIGHT...WHILE AMOUNTS EXCEEDED A FOOT OVER PARTS OF THE TUG HILL.

AS STATED...THE LOW CLOUDS WILL CONTINUE TO MOVE OUT DURING THE
COURSE OF THIS MORNING...BUT HIGH LEVEL CLOUDS WILL START TO STREAM
ACROSS THE REGION DURING THE MIDDAY. THIS SHOULD KEEP MOST AREAS
FROM SEEING A TOTALLY SUNNY DAY... ALTHOUGH CONDITIONS WILL BE
MARKEDLY IMPROVED FROM YESTERDAYS RAW DAMP EXPERIENCE.

ALONG WITH THE RETURN TO PARTIAL SUNSHINE...TEMPS WILL CLIMB BACK
TOWARDS NORMAL. THEY WILL STILL BE A FEW DEGREES BELOW NORMAL
THOUGH. THE SNOW COVER OVER THE HILLS SOUTH OF BUFFALO-BATAVIA AND
ALSO EAST OF LK ONTARIO WILL HELP TO HOLD DOWN THE TEMPS...AS WILL A
SOUTHWEST WIND OFF A VERY CHILLY LAKE ERIE.

CONDITIONS WILL THEN DETERIORATE ONCE AGAIN TONIGHT AS THE NEXT
STORM SYSTEM WILL LIFT OUT OF THE OHIO VALLEY. CLOUDS WILL INCREASE
AND THICKEN ACROSS THE REGION EARLY TONIGHT...THEN RAIN WILL SPREAD
FROM SOUTHWEST TO NORTHEAST DURING THE COURSE OF THE OVERNIGHT. THE
WRN COUNTIES SHOULD PICK UP A QUARTER TO ONE HALF INCH OF RAIN BY
DAYBREAK...WHILE THE EASTERN LAKE ONTARIO REGION WILL PROBABLY GET
LESS THAN A TENTH OF AN INCH. THIS DISPARITY WILL BE EQUALLED OUT ON
MNDAY THOUGH AS THE STORM PUSHED FURTHER EAST.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
IN THE SHORT TERM PERIOD...SIGNIFICANT LOW PRESSURE NEAR ERIE
PENNSYLVANIA MONDAY MORNING IS EXPECTED TO MOVE TO CENTRAL NEW YORK
BY MONDAY EVENING...BEFORE LIFTING NORTHEAST TO NEAR QUEBEC CITY
MONDAY NIGHT...AND INTO CENTRAL QUEBEC ON TUESDAY.

DURING MONDAY...THE STRONG WARM AIR ADVECTION REGIME OUT AHEAD OF
THIS LOW WILL ACT IN CONCERT WITH DEEP CONVERGENCE AT THE NOSE OF A
40-50 KT LOW LEVEL JET...AND A GOOD COUPLED UPPER JET STRUCTURE/
DIFFLUENT FLOW PATTERN ALOFT TO SPREAD A SWATH OF WIDESPREAD PRECIP
ACROSS THE AREA MONDAY MORNING...WITH A NARROW DRY SLOT THEN
PROGRESSING ACROSS THE AREA FROM WEST TO EAST DURING THE LATE
MORNING AND AFTERNOON HOURS. BOUNDARY LAYER TEMPS AND MODEL THERMAL
PROFILES ARE SUPPORTIVE OF PTYPE REMAINING ALL LIQUID RIGHT
THROUGH MONDAY...SO WILL INDICATE A WIDESPREAD SWATH OF
RAIN/CATEGORICAL POPS LIFTING NORTHEAST ACROSS THE AREA MONDAY
MORNING...FOLLOWED BY A TEMPORARY DECREASE TO LIKELY POPS AND
LIGHT RAIN/DRIZZLE AS THE DRY SLOT WORKS ACROSS THE AREA IN THE
LATE MORNING AND AFTERNOON HOURS.

AS WE GET INTO MONDAY EVENING...THINGS WILL GET CONSIDERABLY MORE
INTERESTING AS THE ZONE OF DEEPER WRAPAROUND MOISTURE/DEFORMATION
ZONE PRECIP SLOWLY WRAPS INTO THE AREA ON THE BACKSIDE OF THE
SLOW-MOVING LOW...AND MUCH COLDER AIR QUICKLY FLOODS INTO THE AREA
FROM THE WEST...WITH 850 MB TEMPS DROPPING TO THE -6 TO -8C RANGE
ACROSS MOST AREAS SOUTH OF LAKE ONTARIO BY TUESDAY MORNING. THIS
WILL SUPPORT A FAIRLY RAPID CHANGEOVER FROM RAIN TO SNOW ACROSS THE
WESTERN COUNTIES MONDAY EVENING...WITH THIS CHANGEOVER THEN
SPREADING EAST ACROSS THE REMAINDER OF THE AREA AFTER MIDNIGHT. IN
ANY GIVEN AREA...THE CHANGEOVER FROM RAIN TO SNOW WILL TEND TO START
FIRST AT THE HIGHER ELEVATIONS...THEN WILL PROGRESS TO THE LOWER
ELEVATIONS AS THE ATMOSPHERIC COLUMN COOLS.

ON TUESDAY...WIDESPREAD DEFORMATION ZONE PRECIP WILL CONTINUE ACROSS
THE ENTIRE AREA IN THE WAKE OF THE DEPARTING LOW...WITH 850 MB TEMPS
CONTINUING TO FALL INTO THE -6C TO -10C RANGE AREAWIDE. COMBINED
WITH BOUNDARY LAYER TEMPS IN THE 30S...THIS WILL ALLOW THE BULK OF
THE PRECIP TO CONTINUE TO FALL AS SNOW...THOUGH SOME RAIN MAY MIX
BACK IN AT THE LOWER ELEVATIONS DUE TO STRONG EARLY APRIL DIURNAL
INFLUENCES. THIS MIX WILL BE MOST POSSIBLE FROM THE GENESEE VALLEY
EASTWARD ACROSS THE FINGER LAKES AND NORTH COUNTRY...WHERE THE
ATMOSPHERE WILL LIKELY BE A LITTLE WARMER THAN ACROSS THE FAR
WESTERN END OF THE STATE.

TUESDAY NIGHT...THE WIDESPREAD SYNOPTIC-SCALE PRECIP SHOULD BEGIN TO
DIMINISH FROM SOUTH TO NORTH AS THE LOW LIFTS FURTHER NORTH ACROSS
QUEBEC PROVINCE...HOWEVER LAKE EFFECT PROCESSES WILL LIKELY KEEP THE
ACTIVITY GOING STRONGER/LONGER EAST OF LAKES ERIE AND ONTARIO GIVEN
UNSEASONABLY COLD 850 MB TEMPS OF -10C TO -12C AND THE PREVAILING
WESTERLY LARGE-SCALE FLOW. SUCH TEMPS WILL BE SUPPORTIVE OF JUST
SNOW/SNOW SHOWERS ACROSS THE AREA DURING THIS TIME FRAME.

GIVEN ALL OF THE ABOVE...WE WILL BE MAINTAINING HIGH-END CATEGORICAL
POPS RIGHT THROUGH TUESDAY...WITH VALUES THEN DROPPING TO THE LOW
CATEGORICAL/HIGH LIKELY RANGE TUESDAY NIGHT.

WHILE IT IS STILL A BIT FAR OUT TO PINPOINT EXACT SNOWFALL
ACCUMULATIONS IN THE MONDAY NIGHT-TUESDAY NIGHT TIME FRAME...THE
POTENTIAL DOES EXIST FOR SIGNIFICANT SNOWS ACROSS THE AREA DURING
THIS PERIOD GIVEN THE EXPECTED TRACK AND SLOW-MOVING NATURE OF THIS
SYSTEM...AS WELL AS THE COLDNESS OF THE AIRMASS BEHIND IT...WHICH
WILL BE EVEN COLDER THAN WHAT WE'VE JUST EXPERIENCED WITH THE SYSTEM
PRESENTLY EXITING THE AREA TO THE EAST.

GIVEN CURRENT MODEL PROJECTIONS OF A POTENTIAL 0.50-0.75" OF QPF
ACROSS THE WESTERN HALF OF THE AREA MONDAY AND TUESDAY...THE BULK
OF WHICH SHOULD FALL AS SNOW...WE HAVE DECIDED TO HOIST A WINTER
STORM WATCH FOR MONDAY NIGHT AND TUESDAY FOR AREAS FROM THE
GENESEE VALLEY WESTWARD WITH THE EARLY MORNING PACKAGE. WILL HOLD
OFF ON ANY SUCH FLAGS FOR AREAS FURTHER EAST AT THIS TIME GIVEN
THE LATER START TO THE SNOW AND SOMEWHAT LESSER QPF EXPECTED
THERE...BUT IMAGINE THAT SOME SORT OF WINTER WEATHER FLAG WILL
ULTIMATELY BE NECESSARY FOR THOSE AREAS AS WELL.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
IN THE EXTENDED PERIODS...WE ARE STILL KEEPING THE FORECAST IN LINE
WITH HPC GUIDANCE...WHICH FAVORS YESTERDAY'S ECMWF RUNS THROUGH THE
PERIOD. LARGE DEEP CLOSED LOW WILL REMAIN OVER QUEBEC INTO
WEDNESDAY... KEEPING UNSEASONABLY COLD UNSETTLED WEATHER IN PLACE
WEDNESDAY AND WEDNESDAY NIGHT...WITH SNOW AND RAIN SHOWERS GRADUALLY
WINDING DOWN FROM SOUTH TO NORTH.

ON THURSDAY WILL GO WITH DRY FORECAST AS A WEAK AREA OF HIGH
PRESSURE BUILDS SOUTHEAST OVER THE AREA WITH TEMPS MODERATING...BUT
STILL SOME 5 DEGREES BELOW NORMAL LEVELS.

THURSDAY NIGHT INTO FRIDAY, ANOTHER LOW MOVES NORTHEAST FROM THE
CENTRAL MISSISSIPPI VALLEY ACROSS THE LOWER LAKES. WILL BRING IN
CHANCE POPS DURING THIS PERIOD WITH TEMPS COLD ENOUGH AT NIGHT FOR A
MIX OF RAIN/SNOW SHWRS BUT WAA AHEAD OF THE LOW SHOULD CHANGE THE
PRECIP TO RAIN SHWRS LATER AT NIGHT INTO FRIDAY.

SATURDAY, A SYS PASSES WELL TO OUR SOUTH ACROSS THE MID ATLANTIC
STATES WILL KEEP DRY FORECAST FOR NOW WITH TEMPS STILL RUNNING
SLIGHTLY BELOW NORMAL.

&&

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
A DEEP NEARLY STATIONARY LOW OVER EASTERN MAINE WILL SLOWLY MOVE
EAST EARLY THIS MORNING AND SUNDAY WHILE RIDGING WILL ADVANCE FROM
MICHIGAN AND THE OHIO VALLEY. THIS WILL ALLOW FOR SLOW CLEARING FROM
WEST TO EAST.

AS OF 06Z...PLENTY OF LOW LEVEL MOISTURE IS FOUND OVER MUCH OF WRN
AND PARTICULARLY NORTH CENTRAL NEW YORK. MOST OF THESE STRATO-CU
BASED CIGS ARE AT VFR LEVELS...BUT EAST OF ROCHESTER...THE CIGS
REMAIN AROUND 2500 FT. THESE CIGS WILL RISE TO VFR THRESHOLDS BY MID
MORNING.

ALONG WITH THE GENERAL IMPROVEMENT TO CIGS...THERE WILL BE MUCH LESS
WIND TO DEAL WITH TODAY AS THE RIDGE TO OUR WEST WILL SLOWLY CROSS
THE REGION.

CONDITIONS WILL DETERIORATE TONIGHT AS THE NEXT AREA OF LOW PRESSURE
WILL ADVANCE FORM THE MID WEST. MVFR CIGS WITH SOME RAIN WILL MOVE
ACROSS THE REGION AFTER MIDNIGHT. IN FACT...CIGS WILL LIKELY LOWER
TO IFR LEVELS BY DAYBREAK MONDAY. AS IS USUALLY THE CASE AHEAD OF AN
APPROACHING STORM SYSTEM...THERE WILL BE THE POSSIBILITY FOR SOME
LOW LEVEL WIND SHEAR AFTER MIDNIGHT.

OUTLOOK...
MONDAY...IFR IN RAIN/DRIZZLE.
TUESDAY...IFR IN SNOW.
WEDNESDAY...MVFR IN SNOW SHOWERS.
THURSDAY...VFR.

&&

.MARINE...
WINDS AND WAVES WILL REMAIN ABOVE SMALL CRAFT ADVISORY CRITERIA FOR
ALL NEARSHORE WATERS OF LAKE ONTARIO THROUGH AT LEAST MID
MORNING...THEN WILL DIMINISH FROM WEST TO EAST THROUGH THE LATE
MORNING AND EARLY AFTERNOON HOURS AS A WEAK RIDGE OF HIGH PRESSURE
BUILDS EAST ACROSS THE REGION. AS SUCH...SMALL CRAFT ADVISORIES WILL
REMAIN IN EFFECT FOR THIS LAKE THROUGH AT LEAST MID MORNING.

AS WE GET INTO TONIGHT...LOW PRESSURE WILL LIFT FROM THE OHIO VALLEY
TO NEAR ERIE PENNSYLVANIA. AN INCREASING EAST TO NORTHEASTERLY FLOW
AHEAD OF THIS SYSTEM WILL LIKELY RESULT IN CONDITIONS CLIMBING BACK
ABOVE ADVISORY LEVELS ACROSS THE WESTERN HALF OF LAKE ONTARIO LATE
TONIGHT/EARLY MONDAY. AS SUCH...ADDITIONAL ADVISORIES WILL LIKELY
NEED TO BE ISSUED FOR THIS TIME RANGE LATER ON TODAY.

&&
