AN ICE STORM WARNING REMAINS IN EFFECT FROM 1 PM THIS AFTERNOON

A NEARLY STATIONARY FRONTAL SYSTEM WILL ACT AS A FOCUS FOR A
PROLONGED PERIOD OF INTERMITTENT WINTRY WEATHER THROUGH EARLY

AIRMASS ENTRENCHED NEAR THE SURFACE.

PRECIPITATION HAS TAPERED TO JUST A FEW SCATTERED LIGHT SHOWERS
OR PATCHES OF FREEZING DRIZZLE EARLY TODAY. HOWEVER MORE
PRECIPITATION IS EXPECTED TO REDEVELOP LATER TODAY AND LAST INTO
TONIGHT. WITH TEMPERATURES ONLY EXPECTED TO RECOVER TO WITHIN A
COUPLE OF DEGREES EITHER SIDE OF FREEZING...THE THREAT FOR ICING
WILL REMAIN.

WITH TEMPERATURES EXPECTED VERY NEAR FREEZING FOR THIS
EVENT...CONDITIONS CAN VARY GREATLY OVER A VERY SMALL AREA.
RIDGE TOPS WILL TEND TO STAY COOLEST WHILE VALLEY LOCATIONS COULD
VERY WELL REMAIN JUST A DEGREE OR TWO ABOVE FREEZING. THIS WILL
INCREASE THE THREAT FOR ICING OVER HIGHER ELEVATIONS WHILE VALLEY
AREAS COULD SEE JUST PLAIN RAIN OR DRIZZLE.

AN ICE STORM WARNING MEANS THAT SIGNIFICANT ICE ACCUMULATIONS OF A
QUARTER OF AN INCH OR GREATER ARE EXPECTED. ICE ACCUMULATIONS
WILL LIKELY LEAD TO FALLING TREE BRANCHES AND SNAPPED POWER LINES.
PEOPLE ARE URGED TO BE PREPARED FOR PROLONGED POWER OUTAGES. THE
FREEZING RAIN WILL ALSO MAKE TRAVEL ON UNTREATED ROADS DANGEROUS
OR IMPOSSIBLE. IF YOU MUST TRAVEL... ALLOW EXTRA TIME TO REACH
YOUR DESTINATION...LET SOMEONE KNOW YOUR TRAVEL PLANS AND CARRY A
CELLULAR PHONE.

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE STATE COLLEGE PA
450 AM EST SUN DEC 9 2007

.SYNOPSIS...
A WAVY FRONTAL BOUNDARY LOCATED JUST TO THE SOUTH OF PENNSYLVANIA
TODAY...WILL MEANDER TO THE NORTH AND SOUTH OVER THE NEXT SEVERAL
DAYS AS WAVES OF LOW PRESSURE RIDE NORTHEAST ALONG IT FROM THE
THE OHIO RIVER VALLEY. A WINTRY MIX OF SLEET AND FREEZING RAIN
WILL OCCUR WITH EACH STORM...THE FIRST OCCURRING TODAY AND
TONIGHT...THE SECOND AFFECTING THE REGION TUESDAY INTO TUESDAY
NIGHT...AND A THIRD COMING THURSDAY INTO THURSDAY NIGHT.

BETWEEN EACH WEATHER SYSTEM WILL BE BRIEF PERIOD OF DRY...TRANQUIL
WEATHER AS WEAK AREAS OF HIGH PRESSURE MOVE EAST ACROSS PENNSYLVANIA.

&&

.NEAR TERM /THROUGH TONIGHT/...
OPERATIONAL DETERMINISTIC MODELS AND ENSEMBLES ARE QUITE SIMILAR
TO WHAT WE OBSERVED WITH RESPECT TO PRECIP TIMING (AND TYPE) 24
HOURS AGO. SOME SUBTLE DIFFERENCES BETWEEN MODELS IN REGARD TO
NEAR SFC TEMPS AND WET BULBS MAKE IT DIFFICULT TO PIN DOWN EXACT
AREAS THAT WILL RECEIVE SIGNIFICANT ICE ACCUMULATION LATER TODAY
AND TONIGHT. OBSERVED TEMPS TRENDING CLOSER TO THE WARMER MAVMOS
GUIDANCE IN MOST LOCATION THIS MORNING. GFS SFC WET BULB IS ABOUT 1
DEG C WARMER THAN THE ETAS TONIGHT ACRS MUCH OF THE
REGION...POSSIBLE KEEPING MOST TEMPS AT OR JUST ABOVE 32F OVER NRN
PENN.

BASED ON THE 925-850 HPA THERMAL/WET BULB STRUCTURE...AND THE FAIRLY
WEAK AREA LOW PRESSURE TRACK ACROSS SCENT PENN TONIGHT...FAVORABLE
CONDITIONS SHOULD OCCUR FOR A SIGNIFICANT ICE STORM THROUGHOUT THE
NORTHERN MTNS OF PENN...ESPECIALLY AT ELEVATIONS ABOVE 1600
MSL...WHERE BETWEEN ONE QUARTER AND ONE HALF INCH OF ICE
ACCUMULATION APPEARS LIKELY PER 06Z NAM AND SREF PLUME QPF AND
PRECIP TYPE.

ELSEWHERE...AREAS OF FREEZING RAIN (WITH SOME ICE PELLETS EARLY
TODAY) SHOULD BECOME STEADIER THIS AFTERNOON ACROSS CENTRAL AND
SOUTHERN PENN...AND CHANGE TO MAINLY RAIN. ADDITIONALLY...THE
FRZA WILL SLOWLY BECOME LIMITED TO ELEVATION NEAR OR ABOVE 1600 FT
MSL ACROSS THE CENTRAL MTNS THIS AFTERNOON THROUGH TONIGHT AS TEMPS
IN THE VALLEY FLOORS WARM TO BETWEEN 33 AND 37F.

PRECIP WILL TAPER OFF TO JUST A FEW SHOWERS OF RAIN OR FREEZING
RAIN DURING THE MID TO LATE MORNING HOURS ON MONDAY.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
PRECIP (MAINLY IN THE FORM OF RAIN SHOWERS - MIXED WITH FZRA
ACROSS THE NRN MTNS EARLY MONDAY) WILL DIMINISH/MOVE EAST OF THE
REGION MONDAY AFTERNOON AS A WEAK AREA OF HIGH PRESSURE AND POCKET
OF 850-700 COLD ADVECTION MOVES EAST FROM THE OHIO VALLEY. PARTIAL
CLEARING LATE MONDAY/MONDAY NIGHT WILL BE FLEETING AS THE NEXT WAVE
OF LOW PRESSURE MOVES QUICKLY EAST FROM THE OHIO VALLEY TUESDAY
MORNING.

SREFS AND 00Z MREF SHOW THIS NEXT STORM BEING SLIGHTLY WARMER THAN
THE PRESENT ONE SPREADING THE WINTRY MIX AND ICE ACROSS THE STATE
TODAY/TONIGHT. STILL RAIN OVERSPREADING THE AREA TUESDAY...SHOULD
BEGIN AS FREEZING RAIN AND SLEET UP NORTH...BEFORE CHANGING TO
MAINLY RAIN IN THE AFTERNOON.

ANOTHER BUBBLE OF HIGH PRESSURE MOVES QUICKLY OVER THE STATE
TUESDAY NIGHT AND WED...AGAIN WITH A 12 TO 18 HOUR PERIOD OF
PARTIAL CLEARING...LOW POPS AND NEAR NORMAL DAYTIME TEMPS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
THE 3RD IN THE PARADE OF STORMS WILL STREAM NE INTO THE AREA
THURSDAY. THIS FINAL WAVE WILL ACT SWEEP THE RATHER DEEP MOISTURE
OFF THE EAST COAST FOR FRIDAY INTO NEXT WEEK WITH A LARGE AREA OF
HIGH PRESSURE USHERING IN NEAR NORMAL TEMPS (MAINLY IN THE 30S) WITH
BELOW NORMAL CLIMATOLOGICAL POPS FOR FRIDAY AND SATURDAY.

QPF WITH THIS STORM WILL LIKELY BE THE GREATEST OF ALL THREE WITH
MEAN AMOUNTS AROUND 0.75 OF AN INCH. AGAIN...LLVL THERMAL
STRUCTURE WILL BRING THE CHC FOR MIXED PRECIP OR FREEZING RAIN
DURING ROUGHLY THE FIRST HALF OF THE EVENT...MAINLY THURSDAY
MORNING .

&&

.AVIATION /10Z SUNDAY THROUGH THURSDAY/...
REGIONAL RADAR MOSAIC SHOWS POCKETS OF SLEET /PL/ AND LIGHT RAIN
OVERSPREADING THE AREA FROM WEST TO EAST. PATCHY FROZEN PCPN WILL
BE THE MOST COMMON PTYPE ACROSS THE CNTRL/NRN TERMINALS WITH AREAS
OF RAIN CONFINED TO THE FAR SRN TIER AIRFIELDS WHERE MESONET OBS
CONFIRM SFC TEMPS HOVERING JUST ABV FZG. HOWEVER...CANNOT RULE OUT
SOME PATCHY/ISOLD -PL/FZRA. MOST TERMINALS STILL HOLDING AT VFR
BLW GRADUALLY LOWERING MID LVL CLOUD DECK WITH BASES GNRLY 5-8KFT.
HOWEVER...OCNL MVFR/IFR VIS WILL BE PSBL ESP AT JST WHICH HAS BEEN
DOWN FOR THE LAST FEW HOURS.

SFC HIGH PRES WILL STAY PARKED OVER THE NORTHEAST
TODAY...EFFECTIVELY BANKING/DAMMING COLD /NEAR TO SUB-FZG/ AIR
ACROSS THE REGION. BROAD SSWLY FLOW WILL CONTINUE TO CHANNEL
MOISTURE NEWD INTO THE AREA...WITH SEVERAL EMBEDDED IMPULSES MOVG
ALONG A NEARLY STNRY FNTL BNDRY DRAPED FM THE SRN PLAINS AND ACROSS
THE OH VLY. XPECT CONDS TO DETERIORATE THRU THE NEXT 12 TO 24
HOURS AHEAD OF A WEAK...BUT DISCERNIBLE SFC WAVE RIPPLING NEWD
ALONG THE AFOREMENTIONED BNDRY. FZRA APPEARS TO BE THE DOMINANT
PTYPE AFT 12Z...AS SHALLOW SUB-FZG AIR REMAINS TRAPPED BLW WARM
WEDGE STREAMING IN SEVERAL THOUSAND FEET AGL.

WE MAY SEE A BRIEF BREAK IN CONDITIONS LATER MONDAY NIGHT INTO
TUESDAY BEFORE THE NEXT SYSTEM BRINGS A REPEAT PERFORMANCE FOR
LATER TUESDAY INTO WEDNESDAY. HATE TO BE VAGUE AND REDUNDANT...
BUT IT JUST LOOKS LIKE WE WILL SEE A PROLONGED PERIOD OF MAINLY
DIMINISHED FLYING CONDITIONS TO DOMINATE OVER THE NEXT SEVERAL
DAYS.

IT MAY BE LATE IN THE WEEK UNTIL THE FINAL WAVE MOVES EAST OF THE
AREA...AND WE GET INTO A NW FLOW OF COLDER AIR WITH THE TYPICAL
MID DEC SNOW SHOWERS.
