PREVIOUS DISCUSSION BELOW
**WINTER WEATHER ADVISORY IN EFFECT FOR MUCH OF THE FORECAST AREA
LATE TONIGHT THROUGH EARLY TUESDAY EVENING. WINTER STORM WARNING FOR
SULLIVAN COUNTY**
AN ELONGATED LOW PRESSURE FROM THE DEEP SOUTH AND OHIO VALLEY
WILL SEND MOISTURE INTO THE REGION THAT WILL BE LIFTED INTO A
FAIRLY WIDESPREAD AREA OF SNOW AS THE LOW MOVES NORTHEAST. THIS
SNOW LOOKS TO MOVE THIS MORNING THROUGH MOST OF THE AFTERNOON
HOURS. QPF AMOUNTS HAVE COME DOWN SLIGHTLY GIVEN SOME DRY AIR AT
THE SURFACE. STILL THE GENERAL EXPECTATION OF A QUICK HITTING
3-6 INCHES, LOCALLY 8 FOR SULLIVAN NY REMAINS. 700MB FGEN
FORCING SUGGESTS THE HIGHEST RATES TO BE AROUND AN INCH PER HOUR
FOR THE COURSE OF THE EVENT. ALSO THE POTENTIAL FOR TWO SLIGHTLY
HIGHER LOCAL MAXIMUMS NEAR THE NY/PA LINE AND IN THE
POCONOS/SULLIVAN NY IS STILL PRESENT. WITH TEMPERATURES IN THE
20'S TO LOW 30'S, RATIOS LOOK TO BE AROUND THE TYPICAL 10:1
VALUES.
MESOSCALE MODELING IS PICKING UP ON SOME ADDITIONAL LIGHT SNOW
SHOWER AND FLURRY DEVELOPMENT OVER THE FINGER LAKES AND
PORTIONS OF CNY LATER THIS AFTERNOON AND EVENING. INCORPORATED
THESE MODELS FOR POP GIVEN THE NBM'S TYPICAL STRUGGLES IN THIS
AREA. ANY ADDITIONAL ACCUMULATION WOULD BE MINOR. WITH CLOUDS
HANGING AROUND, TEMPERATURES SHOULD ONLY FALL TO AROUND 20 FOR
MOST OF THE REGION.
HIGH PRESSURE BUILDS INTO THE REGION FOR A SHORT STAY WEDNESDAY.
CLOUDS WILL BE SLOW TO ERODE BUT THE POTENTIAL FOR SOME PEAKS OF
SUN IS PRESENT IN THE AFTERNOON WITH TEMPERATURES NUDGING INTO
THE 30'S.
SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/
TEMPERATURES WON'T FALL MUCH WEDNESDAY NIGHT WITH WARM AIR
ADVECTION ON THE BACKSIDE OF THE HIGH. HOWEVER, A SHARP ARCTIC
COLD FRONT LOOKS TO PUSH THROUGH THURSDAY. TEMPERATURES MAY END
UP FALLING SLIGHTLY THURSDAY INTO THE 20'S.
A FAVORABLE SETUP FOR SOME SNOW SHOWERS AND SNOW SQUALLS IS
PRESENT AS WELL. MOMENTUM TRANSFER OFF OF SOUNDING DATA SHOWS
THE POTENTIAL FOR SOME 20-30 MPH GUSTS COUPLED WITH SLIGHT
AMOUNTS OF CAPE AROUND 30 J/KG. THE FALLING TEMPERATURES ALSO
BRINGS A FLASH FREEZE POTENTIAL UNLIKE EARLIER EVENTS THIS
SEASON. QUICK ACCUMULATIONS UP TO AN INCH COULD OCCUR WITH THIS
SNOWFALL. MORE OF THE FLUFFY VARIETY (HIGHER RATIOS).
THE WINDOW LOOKS TO BE SHORT FOR ANY LAKE EFFECT IN THE
TRADITIONAL LOCATIONS OFF OF LAKE ONTARIO THURSDAY EVENING WITH
HIGH PRESSURE BUILDING INTO THE REGION. STILL SOME ADDITIONAL
FLUFFY ACCUMULATION COULD OCCUR. FOR THE REST OF US IT'S A RACE
TO SEE IF WE CAN CLEAR THINGS OUT OR NOT IN TERMS OF LOW
TEMPERATURES. IF WE DO CLEAR OUT LOWS SHOULD FALL INTO THE
SINGLE DIGITS DUE TO SNOW COVER.
LONG TERM /FRIDAY THROUGH MONDAY/
A COLD BUT DRIER FRIDAY IS CURRENTLY ANTICIPATED UNDER HIGH
PRESSURE. ENSEMBLE GUIDANCE HAS COME INTO BETTER AGREEMENT
SLIDING A SYSTEM TO OUR SOUTH FRIDAY NIGHT. A BROAD NORTHWEST
FLOW WITH WEAK CLIPPER SYSTEMS LOOKS TO TAKE HOLD THIS WEEKEND
WITH ADDITIONAL CHANCES FOR SNOW SHOWERS. THIS LOOKS TO BE
FOLLOWED BY ANOTHER SHOT OF ARCTIC AIR MONDAY.
AVIATION /18Z TUESDAY THROUGH SUNDAY/
SNOW IS BEGINNING TO TAPER OFF SLIGHTLY EARLIER THAN EXPECTED
THIS AFTERNOON. AS A RESULT WE HAVE ALREADY STARTED TO SEE
IMPROVEMENTS IN VISIBILITIES AT ELM/ITH. IMPROVEMENTS WILL
CONTINUE FROM WEST TO EAST AS THE SYSTEM MOVES OUT OF THE
REGION. LINGERING IFR OR WORSE CONDITIONS EXPECTED AT
RME/SYR/BGM/AVP EARLY IN THIS PERIOD BEFORE THE SNOW ENDS.
OTHERWISE MVFR CEILINGS AND VISIBILITIES WILL RETURN FOR
THROUGH THE REMAINDER OF THE PERIOD.
THERE IS A LOW CHANCE OF SPOTTY LAKE EFFECT SNOW SHOWERS OR
FLURRIES BEHIND THE SYSTEM, BUT NO IFR RESTRICTIONS ARE
EXPECTED. WINDS WILL BE LESS THAN 10 KNOTS THROUGH THE PERIOD.
