HITCHCOCK/NIZIOL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
348 AM EST MON JAN 31 2011

.SYNOPSIS...
HIGH PRESSURE WILL BUILD INTO THE GREAT LAKES REGION AND BRING
PARTIAL CLEARING AND COLD TEMPERATURES EARLY THIS MORNING WITH
THICKENING UPPER CLOUDINESS THIS AFTERNOON. A WEAK WAVE OF LOW
PRESSURE WILL BRING A GENERAL LIGHT SNOWFALL TO THE AREA LATE
TONIGHT AND TUESDAY. A STRONGER LOW WILL MOVE THROUGH THE OHIO
VALLEY AT MIDWEEK AND MAY BRING HEAVY SNOW TO MUCH OF THE REGION
LATE TUESDAY NIGHT AND WEDNESDAY WITH A CHANCE OF A WINTRY MIX
ACROSS THE SOUTHERN TIER.

&&

.NEAR TERM /THROUGH TONIGHT/...
DIMINISHING FLURRIES SOUTH OF LAKE ONTARIO WILL DISSIPATE BY MID
MORNING AS HIGH PRESSURE AND STRONGER SUBSIDENCE INVERSION WITH
DRIER AIR QUASHES ANY REMAINING LAKE EFFECT.

WARM AIR/MOISTURE ADVECTION ALOFT WILL BRING AN INCREASE IN MID/HIGH
CLOUDS FROM WEST TO EAST THROUGH THE DAY. IT WILL ALSO BE QUITE
CHILLY WITH A LOW LEVEL ARCTIC AIRMASS IN PLACE. HIGHS WILL ONLY BE
IN THE MID TO UPPER TEENS IN MOST AREAS...AND LIKELY STAY IN THE
SINGLE DIGITS ACROSS THE NORTH COUNTRY.

LIGHT SNOW WILL BECOME LIKELY ACROSS THE SOUTHERN TIER LATE AROUND
MIDNIGHT...THEN HIGH LIKELY TO CATEGORICAL POPS OVER MUCH OF WESTERN
NY BY DAYBREAK TUESDAY. THIS IS THE RESULT OF A BROAD WARM FRONTAL
PATTERN AHEAD OF A MUCH STRONGER SYSTEM DUE TO ARRIVE TUESDAY NIGHT
AND WEDNESDAY. WILL SEE SNOW AMOUNTS OF 1 TO 2 INCHES ACROSS WESTERN
NY LATE TONIGHT...THE HIGHER AMOUNTS ACROSS THE SOUTHERN TIER.

TEMPS WILL FALL ONLY A COUPLE OF DEGREES BY MIDNIGHT THEN HOLD NEARLY
STEADY THROUGH THE OVERNIGHT WITH LOWER TO MID TEENS FOR MUCH OF THE
AREA...AND LOWER TO MID SINGLE NUMBERS EAST OF LAKE ONTARIO.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
SIGNIFICANT WINTER STORM WILL LIKELY IMPACT THE AREA TUESDAY NIGHT
AND WEDNESDAY. WINTER STORM WATCHES WILL BE POSTED THIS MORNING.

ONGOING SNOWS OUT AHEAD OF THE MAIN SYSTEM WILL CONTINUE TO IMPACT
THE REGION THE FIRST HALF OF TUESDAY...BEFORE TAPERING OFF AS THE
INITIAL SWATH OF MOISTURE AND LIFT PUSHES EASTWARD. COULD SEE
ADDITIONAL SNOWFALL AMOUNTS IN THE 1-3 INCH RANGE...ESPECIALLY
FOR SOUTHERN PORTIONS OF THE AREA.

FOLLOWING THIS...THE MAIN STORM SYSTEM WILL IMPACT THE REGION
TUESDAY NIGHT THROUGH WEDNESDAY.

WATER VAPOR IMAGERY EARLY THIS MORNING SHOWING UPPER WAVE DIGGING
THROUGH THE DESERT SOUTHWEST. THIS WAVE WILL EJECT RAPIDLY
NORTHEAST AROUND THE DIGGING INTERMOUNTAIN UPPER TROUGH INTO THE
PLAINS...AND UP THROUGH THE NORTHERN OHIO VALLEY/SOUTHERN GREAT
LAKES BY WEDNESDAY. THERE IS NO SHORTAGE OF DYNAMICS WITH THIS
SYSTEM. MODELS ADVERTISING A VERY IMPRESSIVE UPPER LEVEL JET
COUPLING RIGHT THROUGH THE LOWER LAKES REGION...ALONG WITH AN
ANOMALOUSLY STRONG 65 TO 75 KNOT SOUTHERLY LOW LEVEL JET...5
STANDARD DEVIATIONS ABOVE NORMAL...FORCING OUTSTANDING VERTICAL
MOTION ALONG A TREMENDOUS BAROCLINIC ZONE WHICH WILL EXTEND FROM
THE NORTHERN OHIO VALLEY/SOUTHERN LAKES THROUGH WESTERN NEW YORK.

MODEL QPF ALMOST UNANIMOUS IN SHOWING AMOUNTS OVER AN INCH.
PRECIPITATION TYPE FOR THE MOST PART IS NOT IN QUESTION. AIR MASS
SHOULD BE COLD ENOUGH WITH THE ARCTIC HIGH JUST OFF TO THE NORTH
SUPPLYING FRESH COLD AIR SOUTHWARD FOR AN ALL SNOW SETUP. THE
EXCEPTION MAY BE ALONG THE SOUTHERN TIER...WHERE THERE MAY BE
ENOUGH OF A SURGE OF WARM AIR ALOFT TO BRING THE THREAT FOR A MIX
WITH SLEET. THIS IS SUGGESTED BY THE WARMER GFS.

WIDESPREAD SNOWFALL AMOUNTS IN THE 8 TO 16 INCH RANGE WILL BE
LIKELY...WITH THE BULLSEYE FOR HEAVIEST AMOUNTS FROM THE BUFFALO
TO ROCHESTER TO WATERTOWN CORRIDOR. WE WILL NEED TO BE AWARE OF THE
POTENTIAL FOR DIMINISHED AMOUNTS DUE TO THE SUGGESTION OF A SHARP
DRY SLOT NOSING NORTHWARD ON WEDNESDAY...BUT LIKELY NOT CUTTING
AMOUNTS BELOW WARNING CRITERIA.

IT APPEARS THIS WILL BE A FAIRLY RAPID MOVING SYSTEM...BUT THERE
WILL LIKELY BE A PERIOD OF SEVERAL HOURS...PROBABLY IN THE 06Z/09Z
TO 15Z/18Z TIME FRAME AS A BEST GUESS...WHEN THE SNOWFALL COULD
BE INTENSE WITH RATES EASILY EXCEEDING AN INCH PER HOUR WITH THE
POTENTIAL FOR THUNDER AND LIGHTNING. THIS TIMING WOULD RESULT IN
EXTREMELY HAZARDOUS CONDITIONS DEVELOPING FOR THE WEDNESDAY
MORNING COMMUTE. WIDESPREAD HEAVY SYNOPTIC SNOWS ARE NOT THE NORM
FOR WESTERN NEW YORK...SO IT WILL BE INTERESTING FOR SURE TO SEE
HOW THIS ALL PLAYS OUT.

IN ADDITION TO THE POTENTIAL FOR HEAVY SNOW...A BRISK NORTHEAST WIND
WILL DEVELOP AS THE PRESSURE GRADIENT TIGHTENS WHICH WILL CAUSE A
BLOWING SNOW PROBLEM AS WELL...ESPECIALLY CLOSER TO LAKE ONTARIO.

THE STEADY SYNOPTIC SNOW WILL TAPER OFF FROM WEST TO EAST WEDNESDAY
NIGHT HEADS OUT INTO THE ATLANTIC. THE NORTHWEST FLOW BEHIND THE
DEPARTING STORM WILL GENERATE SOME LAKE EFFECT SNOW SOUTHEAST OF
LAKE ONTARIO.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
STRONG HIGH PRESSURE WORKING IN BEHIND THE DEPARTING WINTER STORM
WILL BRING DRIER AIR INTO THE AIR THURSDAY. WILL STILL MAINTAIN
CHANCE POPS FOR SNOW SHOWERS SOUTHEAST OF LAKE ONTARIO.

CLEARING SKIES THURSDAY NIGHT COULD LEAD TO A VERY COLD NIGHT WITH
LOCATIONS EAST OF LAKE ONTARIO POSSIBLY TO MINUS 10. EXPECT LOW
POSITIVE SINGLE DIGITS ACROSS THE REST OF THE AREA.

EXPECT MAINLY DRY CONDITIONS FRIDAY WITH HIGH PRESSURE FORECAST TO
RIDGE NORTH ACROSS THE OHIO VALLEY AND LOWER LAKES. WILL MENTION LOW
CHANCE POPS FOR SNOW SHOWERS SATURDAY AND SUNDAY WITH WARM AIR
ADVECTION FORECAST TO SET UP AHEAD OF A CENTRAL GREAT LAKES LOW.

&&

.AVIATION /09Z MONDAY THROUGH FRIDAY/...
MVFR CIGS WILL CONTINUE TO SCATTER OUT OVERNIGHT...HOLDING ON
LONGEST SOUTHEAST OF LK ONTARIO. VFR CONDITIONS WILL PREVAIL
MONDAY...WITH THICKENING HIGH AND MID CLOUDINESS THROUGH THE DAY.
LIGHT SNOW FROM THE NEXT SYSTEM SHOULD HOLD OFF UNTIL JUST AFTER
THE 24 HOUR TAF PERIOD...06Z TUES.

.OUTLOOK...
TUESDAY...AREAS OF IFR IN LIGHT SNOW.
LATE TUESDAY NIGHT AND WEDNESDAY...WIDESPREAD IFR IN MODERATE TO
HEAVY SNOW. WINTRY MIX POSSIBLE NEAR THE PA STATE LINE. HIGH IMPACT
WITH VSBY LIKELY BELOW AIRFIELD MINIMUMS FOR THE WEDNESDAY MORNING
PUSH. MANY AIRPORTS ACROSS THE NORTHEAST AND MIDWEST SEVERELY
AFFECTED TUES AND WED.
THURSDAY...IMPROVING TO VFR.
FRIDAY...MAINLY VFR.

&&

.MARINE...
NORTHERLY TO NORTHEASTERLY WINDS WILL BE LESS THAN 10 KNOTS TODAY AS
HIGH PRESSURE BUILDS INTO THE GREAT LAKES REGION AND THE PRESSURE
GRADIENT RELAXES.

A SIGNIFICANT LOW PRESSURE SYSTEM WILL MOVE THROUGH THE OHIO VALLEY
TO SOUTHERN NEW ENGLAND TUESDAY THROUGH WEDNESDAY. NORTHEAST WINDS
WILL BEGIN TO INCREASE TUESDAY AHEAD OF THIS SYSTEM WHICH MAY
WARRANT A SMALL CRAFT ADVISORY FOR TUESDAY...THEN INCREASE FURTHER
TO NEAR GALE FORCE TUESDAY NIGHT AND WEDNESDAY AS THE PRESSURE
GRADIENT TIGHTENS BETWEEN THE LOW AND A STRONG HIGH OVER SOUTHERN
CANADA. WILL LIKELY HAVE SMALL CRAFT ADVISORIES TRANSITIONING TO A
GALE WATCH ON A LATER FORECAST CYCLE AS WINDS INCREASE ON LAKE
ONTARIO...ESPECIALLY ON THE WEST END OF THE LAKE. WINDS WILL SWING
AROUND TO THE NORTHWEST WEDNESDAY NIGHT AS THE LOW REDEVELOPS OFF
THE SOUTHERN NEW ENGLAND COAST.
