A WINTER STORM WARNING REMAINS IN EFFECT FROM 5 AM SUNDAY TO
MIDNIGHT EST SUNDAY NIGHT. 

LOW PRESSURE WILL MOVE ACROSS THE OHIO RIVER VALLEY ON SUNDAY.
WARM MOIST AIR STREAMING NORTH AHEAD OF THIS LOW WILL BE LIFTED
OVER THE THICK LAYER OF COLD AIR IN PLACE ACROSS CENTRAL
PENNSYLVANIA RESULTING IN A MIXED BAG OF PRECIPITATION FOR THE
REGION.

LIGHT SNOW WILL SPREAD OVER THE LAUREL HIGHLANDS AROUND
DAYBREAK...THEN CONTINUE NORTHEAST DURING THE LATE MORNING.

A LAYER OF MILDER AIR ALOFT WILL STREAM NORTH...AND CAUSE THE
SNOW TO POSSIBLY MIX WITH OR CHANGE TO SLEET. FREEZING RAIN COULD
FURTHER COMPLICATE THE FORECAST.

AT THIS TIME EXPECT A WINTRY MIX OF 1 TO 3 INCHES OF SNOW AND
SLEET TO FALL ACROSS THE LAUREL HIGHLANDS AND COUNTIES NEAR THE
MARYLAND BORDER. THIS COULD BE TOPPED BY A LAYER OF FREEZING RAIN
UP TO ONE QUARTER OF AN INCH THICK.

FURTHER NORTH NEAR INTERSTATE 80...3 TO 5 INCHES OF SNOW IS
EXPECTED...ALSO MIXED WITH SOME SLEET OR FREEZING RAIN.

THE AMOUNT OF WARM AIR THAT MOVES IN ALOFT...AND THE AMOUNTS OF
SLEET OR FREEZING RAIN THAT RESULT ARE STILL UNCERTAIN. IF MOSTLY
SNOW OCCURS...ACCUMULATIONS COULD BE AS HIGH AS 5 TO 9 INCHES BEFORE
PRECIPITATION TAPERS TO LIGHT SNOW OR FREEZING DRIZZLE SUNDAY
NIGHT. 

IN ADDITION...IF PRECIPITATION FALLS AS MAINLY SNOW...IT COULD
FALL AT A RATE OF 1 TO 2 INCHES PER HOUR AT THE HEIGHT OF THE
STORM SUNDAY AFTERNOON INTO THE EVENING. THIS WOULD GREATLY
REDUCE VISIBILITY AND CAUSE EXTREMELY HAZARDOUS TRAVEL.

A WINTER STORM WARNING MEANS SIGNIFICANT AMOUNTS OF SNOW OR ICE
ARE EXPECTED OR OCCURRING. ANY TRAVEL IS STRONGLY DISCOURAGED.
THOSE WITH TRAVEL PLANS IN THE WARNED AREA ARE ADVISED TO CHOOSE
AN ALTERNATIVE ROUTE...OR SHOULD USE EXTREME CAUTION IF TRAVEL IS
UNAVOIDABLE. CARRY EXTRA SUPPLIES...INCLUDING BLANKETS...FOOD AND
A CELLULAR PHONE...IN CASE YOUR CAR BECOMES STRANDED.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
1109 AM EST SAT FEB 24 2007

.SHORT TERM /REST OF TODAY THROUGH SUNDAY NIGHT/...

SURFACE HIGH PRESSURE RIDGE EXTENDED FROM THE UPPER GREAT LAKES TO SWRN
PENN LATE THIS MORNING...WHILE A NEARLY NORTH/SOUTH UPPER RIDGE
WAS LOCATED ACROSS THE MIDWEST WITH A THICK SHIELD OF MID/HIGH
CLOUDS ALONG AND JUST TO THE WEST OF ITS AXIS.

NEAR PERFECTLY SUNNY...AZURE BLUE SKIES AND DIMINISHING NW WIND
WILL OCCUR THROUGH MUCH OF TODAY...BEFORE THE WIND BECOMES LIGHT
NE TO EAST OVERNIGHT AND CLOUDS THICKEN UP FROM THE WEST.

WE STILL NOTE THE CONSISTENT ONSET TIMING OF MIXED PRECIP VIA THE
LATEST 09Z SREF...ACROSS THE SW MTNS AROUND 10Z SUNDAY...THEN ALONG
A LINE FROM KBFD TO KUNV AND KMDT BETWEEN 14Z AND 17Z. THIS
CONTINUES TO MESH NICELY WITH THE TIMING OF PRECIP ONSET CONTAINED IN
OUR CURRENT WINTER STORM WATCHES FOR SUNDAY INTO SUNDAY NIGHT
ACROSS ALL BUT THE NRN TIER COUNTIES OF PENN.

EXCELLENT EARLY MORNING DISCUSSION BY MY PREDECESSOR ON SHIFT
HIGHLIGHTS MANY OF THE DETAILS THE AREAS OF POTENTIALLY HEAVIER
SNOW FOR SUNDAY /ACROSS A SLIVER OF COUNTIES IN THE CENTRAL PENN
MTNS AND SUSQ VALLEY/...WITH MAINLY MIXED PRECIP ACROSS THE SRN
ZONES.

09Z SREF CONTINUES RIGHT IN LINE WITH THE 03Z RUN...AND THE 00Z/06Z
MREF AND CANADIAN EPS...BY CARRYING SLEET AS THE PRIMARY PRECIP TYPE
FOR MOST FCST POINTS DURING THE DAY SUNDAY.

THE BEST ARGUMENT FOR HEAVY SNOW IS CONTAINED WITHIN THE PAST 3
OPERATIONAL NAM RUNS /00Z...06Z...AND THE FRESH 12Z DATA/. THIS
SINGLE MODEL RESPONDS MORE /THAN THE MEAN ENSEMBLE SOLUTIONS/ TO THE
INTENSE...SEVERAL HOUR PERIOD OF STRONG UVVEL AND LOW/MID LVL WARM
ADVECTION AT THE NOSE OF A 50-60 KT 850 HPA SOUTHERLY JET...AND
TIPS ITS LLVL WET BULB PROFILE TO A FEW DEG BELOW FREEZING...
SUPPORTING HEAVY SNOWFALL.

SNOWFALL RATES OF 1-2 INCHES PER HOUR COULD FALL WITHIN A 3-6 HOUR
WINDOW DURING THE LATE MORNING AND AFTERNOON HOURS ACROSS MUCH OF
CENTRAL PENN AND THE ENTIRE SUSQ VALLEY BASED ON THIS LONE MODEL
OUTLIER. A PURE...10 TO 1 SNOW WATER RATIO /TYPICAL OF WARM
ADVECTION SNOW/ OFF THE NAM WOULD MEAN 5-9 INCHES OF SNOW FOR
MOST OF CENTRAL PENN AND THE ENTIRE SUSQ VALLEY SUNDAY AFTERNOON
AND EVENING.

OTHERWISE...MEAN LIQ EQUIVALENT FOR SLEET VIA THE 03/09Z SREFS IS
0.30-0.40 ACROSS MUCH OF CENTRAL PENN AND PRACTICALLY THE ENTIRE
WINTER STORM WATCH AREA. A ROUGH...3 TO 1 SLEET/WATER RATIO WOULD
MEAN A SOLID INCH OR MORE OF SLEET LATE SUNDAY MORNING AND AFTERNOON.

A KEY ELEMENT IN THE PRECIP TYPE MAY REST ON THE DEPTH OF THE VERY
DRY AIR...AND DEGREE OF RADIATIONAL COOLING EARLY TONIGHT.
OPERATIONAL MODELS AND SREFS HAVE TRENDED /IF ANYTHING/ A FEW HOURS
LATER WITH THE THICKER CLOUDS AND PRECIP ONSET ACROSS CENTRAL PENN
AND THE SUSQ VALLEY...TO THE LATE MORNING/EARLY AFTERNOON HOURS.

FOR THE LATE MORNING UPDATE TO THE WINTER STORM WATCHES...WILL BE
EMPHASIZING THE PRECIP RATES...AND OUTSIDE SHOT AT 1-2 INCH/HR
SNOWFALL RATES IN MANY AREAS. WILL ALSO ISSUE A PHLSPSCTP FOR THE
LIKELIHOOD OF SEVERAL INCHES OF SNOW...POSSIBLY MIXED WITH SLEET
ACROSS THE NORTH. THERE...A 3RD PERIOD WINTER WEATHER ADVISORY
MAY BE ISSUED WITH THE LATE AFTERNOON ZONE PACKAGE...WHILE WATCHES
ARE UPGRADED TO WINTER STORM WARNINGS ELSEWHERE AFTER DIGESTING
THE 12Z GFS AND MREF.

.PREV DISCUSSION...
/ISSUED 406 AM EST SAT FEB 24 2007/

SHORT TERM /TODAY THROUGH TONIGHT/...
QUIET WEATHER IN THE NEAR TERM ACROSS CENTRAL PA WITH SFC HIGH
WEDGED FROM NW TO SE FROM THE CENTRAL GLAKS TO THE SOUTHEAST
ATLANTIC COAST PROVIDING MAINLY CLEAR SKIES FOR THE DAYLIGHT
HOURS. SOME HIGH CLOUDS SPILLING OVER THE SHARP 5H RIDGE AXIS OVER
THE WESTERN GLAKS THIS MORNING MAY EVENTUALLY FILTER THE SUN OVER
WESTERN SECTIONS AS THE DAY WEARS ON...AS THE 5H RIDGE AXIS
PROPOGATES INTO THE CENTRAL OHIO VALLEY THIS AFTERNOON.

SFC RIDGE WILL PROPOGATE SLIGHTLY EASTWARD THIS EVENING AS UPPER
RIDGE AXIS REACHES THE OH/PA BORDER BY 06Z. RAPID MOISTURE RETURN
WEST OF THE UPPER RIDGE AXIS THIS MORNING OVER WI...WITH HEAVY
SNOW FALLING WITHIN THE AXIS PRESENTLY. WILL LIKELY SEE A SIMILAR
RAPID MOISTENING TONIGHT WITH PRECIPITATION BREAKING OUT NEAR AND
JUST WEST OF THE UPPER RIDGE AXIS OVERNIGHT AS THE WARM ADVECTION
COMMENCES IN EARNEST. CLOSE EXAMINATION OF AVAILABLE MODEL
FORECAST SOUNDINGS INDICATES PRELIMINARY PRECIPITATION TYPES
MAINLY SNOW WITH SOME SLEET MIXED IN MAINLY SOUTH OF THE TURNPIKE.

LONG TERM /SUNDAY THROUGH FRIDAY/...
PRECIPITATION WILL COMMENCE EASTWARD THROUGHOUT CENTRAL PA SUNDAY
MORNING. GFS/NAM FORECAST SOUNDINGS INDICATE MAINLY SNOW PROFILES
INITIALLY...MIXED WITH SLEET GENERALLY SOUTH AND EAST OF
LEWISTOWN. 00Z RUN WAS DECIDEDLY COLDER WITH LESS OF A FREEZING
RAIN THREAT INDICATED. SREFS DEPICT A BIMODAL PRECIPITATION
DISTRIBUTION WITH SEVERAL MEMBERS CLUSTERING AROUND .4-.5 W.E.
AND REMAINING MEMBERS CLUSTERING AROUND .8 TO .9 WATER EQUIVS FOR
CENTRAL AND EASTERN PA. AMOUNT OF LIQUID THAT FALLS WILL BE
CRITICAL FROM A WINTER STORM VERIFICATION STANDPOINT...IN ADDITION
TO HOW MUCH SLEET IS MIXED WITH THE SNOW. AT THIS TIME...THINK
THAT BEST CHANCES FOR 6 INCHES OR MORE OF SNOW IS IN A FAIRLY
NARROW CORRIDOR FROM BLAIR AND CENTRE COUNTIES ENE THROUGH
SOUTHERN LYCOMING AND COLUMBIA COUNTIES. SOUTH OF THESE AREAS MORE
SLEET WILL BE MIXED IN...AND POSSIBLE FREEZING RAIN. FURTHER SOUTH...
DESPITE THE COLDER 00Z RUN...FZRA POTENTIAL REMAINS AND THUS WILL
HOLD ONTO THE EXISTING WATCHES. AGAIN...TOTAL W.E. FROM THIS STORM
WILL BE THE DETERMINING FACTOR AND BIMODAL DISTRIBUTION TO SREFS
MAKES THIS A DIFFICULT CALL. MREFS ARE MOSTLY CLUSTERED AROUND THE
5 TO .6 W.E. MARK...WHICH IS PERFECTLY MARGINAL. ALL GUIDANCE
POINTS TO CONTINUING CURRENT WINTER STORM WATCHES...WHILE
EXPANDING SLIGHTLY NORTH TO INCLUDE ELK...CAMERON...AND LYCOMING
COUNTIES FOR POTENTIAL 6 SNOW/SLEET ACCUM.

SECONDARY COASTAL DEVELOPMENT SUNDAY AFTERNOON AND EVENING WILL
ROB OUR REGION OF THE BEST MOISTURE BY SUNDAY NIGHT...BUT PARENT
LOW CIRCULATION STILL PROGGED TO MEANDER EASTWARD INTO THE EASTERN
GLAKS INTO MONDAY...WITH DEFORMATION BETWEEN 2NDARY LOW AND PARENT
CIRCULATION KEEPING LOW CHANCE SNOW POPS GOING THROUGH MOST OF
MONDAY...AND EVEN INTO TUESDAY AS UPPER LOW FILLS VIRTUALLY OVERHEAD.

UPPER RIDGE AXIS WILL NUDGE THE REMAINS OF THE FILLING UPPER LOW
EASTWARD BY LATE WEDNESDAY WITH SFC RIDGE AXIS EXTENDING SOUTHWARD
FROM THE EASTERN LAKES TO THE MID ATLANTIC COAST. ANOTHER MESSY
STORM APPEARS IN THE OFFING FOR LATE IN THE WEEK.

AVIATION /09Z-06Z/...
VFR FLYING CONDITIONS ARE EXPECTED AT ALL TAF SITES THROUGH THE
PERIOD AS AN AREA OF HIGH PRESSURE MOVES ACROSS THE REGION FROM THE
WEST.

STRONG NORTHWEST WINDS WILL CONTINUE OVERNIGHT BUT DECREASE DURING
THE DAY SATURDAY AS SFC PRESSURE GRADIENT RELAXES.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL
PENNSYLVANIA.

.DAY ONE...THIS AFTERNOON AND TONIGHT

NO HAZARDOUS WEATHER IS EXPECTED.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A WINTER STORM WATCH REMAINS IN EFFECT FOR SUNDAY MORNING UNTIL
MIDNIGHT SUNDAY NIGHT.

LOW PRESSURE HEADED INTO THE OHIO VALLEY SUNDAY WILL PUSH AN AREA
OF SNOW OR SLEET INTO THE LAUREL HIGHLANDS SHORTLY BEFORE DAYBREAK
SUNDAY. THE MIXED PRECIPITATION OR SNOW WILL START ACROSS THE LOWER
SUSQUEHANNA VALLEY AND ADJACENT PORTIONS OF SOUTH CENTRAL
PENNSYLVANIA DURING THE MID TO LATE MORNING HOURS SUNDAY...AND
BEGIN IN COMMUNITIES THROUGHOUT THE CENTRAL SUSQUEHANNA VALLEY DURING
THE MID DAY HOURS...AND CONTINUE ACROSS ALL AREA INTO SUNDAY
EVENING. THE MIXED PRECIPITATION OR SNOW COULD FALL HEAVY AT
TIMES.

AT PRESENT...EXPECTED SNOWFALL AMOUNTS BY SUNDAY NIGHT RANGE FROM
BETWEEN 2 AND 4 INCHES ACROSS MUCH OF SOUTHERN PENNSYLVANIA...TO
AS MUCH AS 5 INCHES ACROSS THE COUNTIES NEAR AND JUST TO THE NORTH
OF INTERSTATE 80.

A CHANGEOVER TO SLEET OR FREEZING OCCURS WILL LIKELY OCCUR IN MANY
LOCATIONS THROUGHOUT CENTRAL AND SOUTHERN PENNSYLVANIA LATE IN THE
DAY SUNDAY OR SUNDAY EVENING. THE SLEET COULD ACCUMULATE ANOTHER
HALF INCH TO ONE INCH ON TOP OF THE SNOW. SLIGHTLY HIGHER SNOWFALL
AMOUNTS ARE POSSIBLE NEAR INTERSTATE 80.

THERE STILL IS A LOWER PROBABILITY THAT THE BULK OF THE
PRECIPITATION COULD FALL AS MAINLY SNOW. IN THIS
CASE...SNOW ACCUMULATIONS WOULD BE HIGHER AND IN THE 5 TO 8 INCH
RANGE BEFORE ANY CHANGEOVER TO LIGHTER SLEET OR FREEZING RAIN
OCCURS LATE SUNDAY AND SUNDAY NIGHT.

IF ALL SNOW OCCURS FOR SEVERAL HOURS SUNDAY AFTERNOON...IT COULD
FALL AT A RATE OF 1 TO 2 INCHES PER HOUR. GREATLY REDUCING
VISIBILITY TO ONE HALF OF A MILE OR LESS.

ADDITIONALLY...A PERIOD OF SIGNIFICANT ICE ACCUMULATION OF OVER
ONE QUARTER OF AN INCH MAY OCCUR ACROSS THE LOWER SUSQUEHANNA
RIVER VALLEY...ON TOP OF THE SNOW AND SLEET LATE SUNDAY INTO
SUNDAY NIGHT.

A WINTER STORM WATCH MEANS THERE IS A POTENTIAL FOR SIGNIFICANT
SNOW OR ICE ACCUMULATION THAT MAY IMPACT TRAVEL. THE EXACT PATH OF
THIS STORM SYSTEM IS UNCERTAIN. HOWEVER...IF HEAVY SNOW OR ICE
BECOMES IMMINENT...A WINTER STORM WARNING WILL BE ISSUED.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS ARE REQUESTED TO REPORT TO THE NATIONAL WEATHER SERVICE SNOW
ACCUMULATION OF 3 INCHES OR MORE AND SIGNIFICANT ICE OR SLEET
ACCUMULATION.
