AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
629 PM EST SUN DEC 30 2007
.SYNOPSIS...
A STORM WILL MOVE NORTHEAST ALONG THE EAST COAST TODAY INTO
MONDAY...BRINGING SNOW TO THE REGION. AN ARCTIC COLD FRONT WILL
CROSS THE AREA ON TUESDAY... ACCOMPANIED BY MORE SNOW... AND
FOLLOWED BY MUCH COLDER WEATHER.
&&
.NEAR TERM /UNTIL 11 PM THIS EVENING/...
INITIAL SHOT OF LIGHT SNOW IS WORKING NORTHEAST ACROSS CENTRAL PA
LATE THIS AFTERNOON. SOME VERY LIGHT SNOW WILL SPREAD ACROSS
NORTHEAST PA THROUGH 5 PM... BUT THIS PROGRESSION WILL LIKELY SLOW
AS THE PRECIPITATION BEGINS TO OUTRUN ITS FORCING. MAIN SHOT OF
LIFT IS STILL EXPECTED TO OVERSPREAD THE AREA THIS EVENING... AND
THIS IS THE TIME WHEN SNOW SHOULD EXPAND ACROSS THE ENTIRE
FORECAST AREA.
THERE IS STILL A CONCERN FOR SOME MIXED PRECIPITATION DURING THE
ONSET OF THIS EVENT ACROSS NORTHEAST PA. THE GFS FORECAST SOUNDING
AT AVP IS WARM ENOUGH TO SUPPORT MIXED PRECIPITATION UNTIL AROUND
06Z. THE NAM... LOCAL ARW AND RUC ARE SOMEWHAT COLDER AND WOULD
CONFINE MIXED PRECIPITATION MAINLY TO AREAS SOUTH OF I-80.
THE BEST FORCING FOR LIFT STILL APPEARS TO BE ACROSS THE
SOUTHEASTERN HALF OF THE FORECAST AREA LATE THIS EVENING THROUGH
ABOUT 09Z WHEN SIGNIFICANT FRONTOGENESIS IS FORECAST TO DEVELOP
CO-LOCATED WTIH REDUCED STABILITY. THIS SHOULD FORCE A BAND OF
MODERATE TO HEAVY SNOW FROM THE NORTHERN POCONOS NORTHEAST INTO
THE CATSKILLS. HAVE GONE WITH A HEAVY SNOW WARNING FOR UP TO 8
INCHES IN THAT AREA. FARTHER TO THE WEST... BANDING SIGNALS ARE
NOT AS IMPRESSIVE... BUT BROAD-SCALE LIFT FOR SEVERAL HOURS SHOULD
STILL BE ENOUGH TO PRODUCE A WIDESPREAD 3 TO 6 INCH SNOW EVENT.
&&
.SHORT TERM /11 PM THIS EVENING THROUGH TUESDAY/...
NEXT SYSTEM WILL PARADE THRU THE FA LATE MONDAY NIGHT THROUGH
TUESDAY. THIS SYSTEM IS CURRENTLY LOCATED OVER PACIFIC NORTHWEST
AND IS PROGGED TO DIVE INTO THE PLAINS OVRNGT. SFC LOW WILL
DEVELOP IN RESPONSE AND CROSS THE OHIO VALLEY...APPCHG WNY BY 12Z
TUESDAY. LATEST NAM GUIDANCE INDICATES H7 LOW WILL CLOSE OFF OVR
FA WITH H5 RMNG FAIRLY OPEN AS IT MVS OVR CENTRAL FA. NAM GUIDANCE
HAS BEEN TRENDING A LITTLE FURTHER SOUTH WITH UPPER FEATURES. NOT
A WHOLE LOT OF DIFFERENCE BTWN NAM AND GFS THUS FAR AS BOTH CLOSE
OF H7 LOW TO SOME EXTENT AND LV H5 FEATURE MORE AS IN OPEN
TROF...ALBEIT GETTING A LITTLE STRONGER AND DEEPER.
SFC LOW IS PROGGED TO TRACK ALONG THE NY/PA BORDER ON TUESDAY. AT
THIS POINT...NAM DIFFERS IN THAT IT TRANSFERS ENERGY MORE TOWARD THE
COAST AND RE-DEVELOPS LOW ALONG ERN SEABOARD WHILE GFS KEEPS A MORE
CONSOLIDATED LOW INLAND. ALL THESE FEATURES WILL COME INTO PLAY
REGARDING SNOWFALL AMNTS. FOR THE TIME BEING...HAVE GONE WITH A
BLEND OF NAM/GFS QPF. BOTH MODELS INDICATE A POSSIBLE DRY SLOT TUE
AFTERNOON AND THIS WILL DEPEND ON HOW FAR SOUTH H5 FEATURE
EVENTUALLY TRACKS. BASED ON POSN OF SYSTEM THUS FAR...HAVE GONE WITH
QPF FROM 0.25-0.50 INCHES FROM 00Z MON-00Z TUE. LESSOR AMNTS
EXPECTED DOWN SOUTH IF DRY SLOT MATERIALIZES WITH HIGHER TOTALS OVR
FINGER LAKES. PART OF THIS MAY BE ENHANCED BY LK EFFECT AS FLOW
TRANSITIONS QUICKLY.
LIMITING FACTOR FOR HIGH SNOWFALL TOTALS WILL BE LACK OF MOISTURE.
EARLIER SYSTEM WILL TAKE A GOOD CHUNK OF THE MOISTURE WITH IT AND
NOT EXPECTING A WHOLE LOT IN THE WAY OF RETURN AHEAD OF THIS NEXT
SYSTEM. THAT BEING SAID THOUGH...COMPROMISE QPF BTWN NAM (MUCH
HEAVIER OF THE TWO) AND GFS WUD STILL YIELD WARNING CRITERIA SNOWS
FROM FINGER LAKES INTO ONEIDA CTY AND POSSIBLE ADVISORY DOWN TO THE
SRN TIER...POSSIBLY ENHANCED DUE TO LAKE EFFECT. CUD SEE A BRIEF MIX
WITH SLEET OVR NEPA WHERE LOWEST AMNTS ARE EXPECTED AS OF NOW. HAVE
OPTED NOT TO ISSUE A WATCH FOR THIS SYSTEM AS OF YET DUE TO ONGOING
WINTER HEADLINES. HOWEVER...WILL PLAY IT UP IN THE HWO FOR POSSIBLE
SIGNIFICANT ACCUMS.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
MAIN STORY DURING FIRST HALF OF THE EXTENDED PERIOD WILL BE MUCH
COLDER AIRMASS AND LAKE EFFECT SNOW SHOWERS AS UPPER LEVEL LOW
PRESSURE MOVES EAST ACROSS THE AREA AND COLD NORTHWEST FLOW
ENSUES. AT THIS POINT, IT LOOKS LIKE THE FLOW WILL BE SUCH THAT
THE LAKE EFFECT WILL BE PRIMARILY A LONG-LIVED, MULTI-BAND EVENT
TARGETING AREAS SOUTH OF THE LAKES, AND THE FINGER LAKES REGION OF
NEW YORK FROM TUESDAY NIGHT INTO THURSDAY. AFTER THAT, QUICK
MODERATING TREND AS UPPER RIDGE AND HIGH PRESSURE AT SFC MOVE EAST
TO COVER MOST OF THE EASTERN HALF OF THE COUNTRY. TEMPS LOOK TO
REBOUND QUICKLY TO ABOVE NORMAL VALUES BY THE END OF THE PERIOD.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
IFR IN -SN AND CIG SPREADING N QUICKLY INTO NRN PA AND SC NY WITH
AVP DOWN TO IFR ALREADY...BGM AT MVFR. I EXPECT TAFS SITES ELM...BGM AND
