AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
237 AM EST WED FEB 14 2007

.SHORT TERM /TODAY THROUGH THURSDAY/...

A LAYER OF MILDER...SLIGHTLY ABOVE FREEZING AIR SURGED NORTH
ACROSS SOUTHERN AND CENTRAL PENN LATE TUESDAY EVENING. THE DEPTH
OF THIS ELEVATED WARM LAYER /BETWEEN 4-7 KFT AGL...OR FROM 850 HPA
TO 750 HPA/ IS NEAR IT/S PEAK ATTM NEAR KUNV AND KIPT...AND WILL
BE PUSHED EAST/DISSIPATE AS AN AREA OF VERY STRONG UVVEL /LASTING
3-6 HOURS ACROSS MUCH OF THE CENTRAL PENN MTNS/ DEVELOPS IN
ASSOCIATION WITH STRENGTHENING MID LEVEL FRONTOGENESIS TO THE N/NW
OF A DEVELOPING 700 HPA CLOSED LOW OVER SERN PENN.

OPERATIONAL GFS AND NAM TIMESECTIONS OF TEMP/PRECIP TYPE APPEAR TO
BE HANDLING THIS SEVERAL HOUR WINDOW OF MIXED PRECIP ACROSS THE
CENTRAL RIDGE AND VALLEY REGION EXTREMELY WELL. BOTH MODELS INDICATE
THAT A CHANGEOVER BACK TO MDT/HVY SNOW WILL OCCUR BETWEEN 08-11Z AT
KUNV AND KIPT...BUT NOT UNTIL AFTER 12Z WELL SE OF KUNV...WHERE ONLY
A FEW INCHES OF ADDITIONAL SNOW COULD FALL TODAY. FOR KUNV...ANOTHER
3 TO 5 INCHES OF SNOW IS LIKELY...WITH AROUND 6 INCHES IF SLIGHTLY
EARLIER CHANGEOVER TO SNOW OCCURS. JUST NORTHEAST KIPT...4 TO 8
INCHES OF ADDITIONAL SNOW SHOULD FALL...WITH UPWARDS OF 8 TO 10
POSSIBLE BASED ON SIMILAR ADDITIONAL LIQ EQUIVALENT QPF OF NEARLY
1.00 INCH...BEFORE TAPERING TO SNOW SHOWERS LATE IN THE AFTERNOON.

SHORT RANGE OPERATIONAL MODELS AND 21Z SREF/00Z MREF PLUME
DIAGRAMS POINT TWD ANOTHER WHOPPING 0.70 TO 1.50 INCHES OF QPF IN
THE FORM OF MAINLY SLEET THROUGH LATE THIS MORNING ACROSS THE
LOWER SUSQ VALLEY...BEFORE A CHANGEOVER TO PERIODS OF LIGHT SNOW
IN THE AFTERNOON WITH ANOTHER INCH OR SO POSSIBLE.

THIS EXTENDED PERIOD OF SLEET WE/RE ABOUT TO EXIT FROM...AMOUNTED TO
BETWEEN 0.40 AND 0.60 OF AN INCH OF LIQ EQUIV NEAR THE I-80
CORRIDOR...AND HAS EFFECTIVELY TRIMMED STORM TOTAL SNOW AMOUNTS BY 4
TO 7 INCHES.

HOWEVER...THE REAL SNOW ACCUMULATION IS JUST GETTING STARTED FOR OUR
NE MTN ZONES...WHERE SOME SLEET WILL MIX IN WITH THE SNOW FOR THE
NEXT FEW HOURS...BEFORE CHANGING OVER TO HEAVY SNOW. AGAIN...UP TO
ANOTHER 10 INCHES OR MORE IS LIKELY ABOUT 30 OR 40 MILES NORTH AND
NE OF KIPT. 18Z MREF PLUME DIAGRAMS AND OPERATIONAL GFS SHOW THE
HEAVIEST PRECIP RATES FROM THE MID MORNING THROUGH EARLY AFTERNOON
THERE...AS WE LOSE THE SHALLOW MID LEVEL WARM LAYER.

NEW...00Z MREF ALSO CONFIRMS THE CHANGE BACK TO MDT OR HVY SNOW FOR
A FEW HOURS AT KUNV WITHIN OR SHORTLY AFTER THE 09-11Z WINDOW...WITH
AN ADDITIONAL 0.30 LIQ EQUIV FALLING AS SNOW TODAY. A SIMILAR
OCCURRENCE FROM HEAVY SKEET TO SNOW WILL OCCUR BETWEEN 10-12Z AT
KIPT FOLLOWED BY 3 TO 5 INCHES OF SNOW LATER THIS MORNING THROUGH
THE AFTERNOON. PRECIP APPEARS TO BE CHANGING BACK TO ALL SNOW ACROSS
THE WRN PENN MTNS NEAR KDUJ AND KFIG...AND MORE SNOW THAN SLEET IS
FALLING OUTSIDE OUR OFFICE WINDOW ATTM.  ANOTHER 4 TO 5 INCHES OF
SNOW IS LIKELY IN THE KBFD AREA BASED ON THE MREF...THOUGH
INCREASING SNOW/WATER RATIOS COULD YIELD UP TO 6 INCHES IN SOME
SPOTS.

THE ABOVE CHANGEOVER TIMES AND ADDITIONAL SNOWFALL VALUES TODAY AGREE
VERY WELL WITH THE 6 HOURLY SNOW GRIDS MODIFIED BY THE PAST FEW
SHIFTS...ADJUSTING FOR THE SEVERAL HOURS OF SLEET. STORM TOTALS WILL
BE A SOLID 14 TO 20 INCHES ACROSS THE NRN MTNS...WITH STILL A CHC
FOR 2 FEET NE OF KIPT...ESP ACROSS THE HIGHER TERRAIN OF SULLIVAN
AND TIOGA COUNTIES. WILL BE TRIMMING STORM TOTAL AMOUNTS DOWN BY A
FEW INCHES ACROSS THE CENTRAL SUSQ VALLEY...AND CENTRAL/SOUTHERN
PENN MTNS...FROM KAOO...TO KUNV AND KIPT.

A POSITIVE ASPECT TO THE THICK LAYER OF SLEET...IS THAT THE EXTENT
OF BLOWING AND DRIFTING OF THE SNOW WILL BE LESSENED LATE TODAY INTO
THURSDAY AS NW WINDS INCREASE TO 20 TO 30 MPH WITH GUSTS OVER 40
MPH...AS THE LOW PRESSURE AREA DEEPENS ALONG THE NEW ENGLAND COAST.
THE GREATEST IMPACT FROM THE BLOWING AND DRIFTING WILL BE ACROSS THE
NCENT AND NW MTNS.

VERY COLD TEMPS OF 10 TO 15 ACROSS THE NW MTNS TODAY AND TEENS TO
LOWER 20S ELSEWHERE...WILL COMBINE WITH THE INCREASING WIND TO DROP
WIND CHILLS DOWN TO BETWEEN 5 AND 10 BELOW ZERO FROM KJST TO KBFD
THIS AFTERNOON AND EVENING...AND AROUND 5 ABOVE ACROSS THE SUSQ
VALLEY.

WIND CHILL/BLOWING SNOW ADVISORIES WILL BE NEEDED FOR LATER
TONIGHT...THROUGH PERHAPS MUCH OF THURSDAY ACROSS THE CENTRAL AND NW
ZONES WHERE WIND CHILLS WILL AVERAGE BETWEEN 15 AND 20 BELOW ZERO.
WIND CHILLS ACROSS THE LOWER SUSQUEHANNA VALLEY WILL STAY BETWEEN
ZERO AND 10 BELOW LATE TODAY THROUGH THURSDAY.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...

A FAIRLY STRONG...MID AND UPPER LEVEL THERMAL TROUGH /700 HPA
TEMPS NEAR -25C/...COMBINED WITH A GOOD UPSTREAM BOUNDARY LAYER WIND
TRAJECTORY OFF THE UPPER GLAKES WILL BRING NUMEROUS SNOW SHOWERS
ACROSS THE NRN AND WESTERN MTNS WITH A FEW INCHES OF ACCUMULATION
POSSIBLE THURSDAY NIGHT/FRIDAY.

A SLIGHT WARMUP...INTO THE UPPER TEENS NW...AND 20S ELSEWHERE WILL
OCCUR ON SATURDAY AS CLOUDS THICKEN UP AND LIGHT SNOW OR SNOW
SHOWERS SPREADS EAST ACROSS THE REGION IN ASSOCIATION WITH QUICK
MOVING...CLIPPER EMBEDDED IN THE WEST/NW FLOW ALOFT. THIS SYSTEM HAS
THE POTENTIAL TO BRING A GENERAL 1-3 INCH SNOWFALL...WITH THE HIGHER
AMOUNTS ACROSS THE NRN PENN MTNS.

COLDER AIR /SIMILAR TO TEMPS TODAY AND THURSDAY/ FOLLOWS FOR SUNDAY
INTO MONDAY WITH SCTD TO LIKELY POPS FOR SNOW SHOWERS ACROSS THE
MTNS...AND GENERALLY FLURRIES ACROSS THE CENTRAL RIDGE AND
VALLEY/SUSQ VALLEY.

&&

.AVIATION /07Z-06Z/...

IFR/LIFR CONDS EXPECTED TO PREVAIL THRU MUCH OF THE DAY
TODAY...BEFORE BECOMING LIMITED TO MAINLY THE NRN AND WRN MTNS
/FROM KJST...TO KBFD AND KELM TONIGHT AND THURSDAY MORNING/.

A SHHLLOW WEDGE OF WARMER AIR ALOFT LOCATED BETWEEN 4-7 KFT AGL
STREAMING IN FROM THE SOUTH WILL MAINTAIN A MIXTURE OF SLEET /PL/
OR EVEN SOME FREEZING RAIN /FZRA/ ACROSS THE SOUTHERN
TERMINALS...MAINLY SOUTH OF A LINE FROM KAOO TO KSEG THIS MORNING.
THIS WARM LYR IS COURTESY OF A STRONG 50KT LLJ...WHICH WILL ALLOW
FOR LLWS AT ALL TAF SITES EXCEPT FOR KJST AND KBFD.

NERLY SFC WNDS WILL BACK TO THE NORTHWEST TOWARD THE END OF THE
PD AS A DEEP COASTAL LOW RIPS NEWD ALONG THE MID ATLANTIC AND NEW
ENGLAND SEA BOARD. WNDS WILL INCREASE BY WED AFT /15-20KTS WITH
HIGHER GUSTS/ AND MAY CAUSE SOME BLSN ESP ACROSS THE HIGHER
ELEVATIONS.
