AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
121 PM EST TUE DEC 30 2008

.SYNOPSIS...
THE LARGE SCALE PATTERN CONTINUES TO SHOW AN ANOMALOUS RIDGE OVER
GREENLAND WITH A TROUGH BENEATH THE RIDGE OVER EASTERN NORTH
AMERICA. THIS WILL KEEP OUR REGION ACTIVE WITH A SERIES OF WAVES
MOVING IN THE FAST FLOW ACROSS OUR REGION AT FAIRLY REGULAR
INTERVALS FOR THE NEXT 2-7 DAYS. THE RIDGE APPEARS TO BE HIGHLY
PREDICTABLE AND SHOULD PERSIST FOR A PROLONGED PERIOD OF TIME.

&&

.NEAR TERM /THROUGH TONIGHT/...
WINDS GUSTY NOW...BUT ARE BEGINNING TO SLACKEN AS THE FRONT HAS
GONE THROUGH AND PRESSURES LEVELING OFF. GUSTS TO 40 MPH ARE STILL
EXPECTED THROUGH THE MORNING. THERE MAY BE A FLURRY ACROSS THE
NORTHERN TIER EARLY THIS MORNING...BUT WILL NOT MENTION AS THE
AIRMASS IS DRY AND CIGS PRETTY HIGH.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
WINDS WILL CONTINUE TO DIMINISH AS THE DAY CONTINUES...AND HIGH
PRESSURE BUILDS IN. RIDGE AXIS RUNNING N-S IS RIGHT OVERHEAD LATE
TODAY.

BUT ANOTHER CLIPPER CAUGHT IN THE VERY FAST WESTERLY FLOW
WILL ZIP W-E DIRECTLY OVERHEAD THROUGH PA LATE TONIGHT AND WED
MORNING. THE SWEET SPOT FOR SNOW WILL BE ACROSS NRN TIER AND WRN
NY. THE S:W RATIOS SHOULD BE 20:1 OR BETTER/FLUFFIER WITH GOOD
UP MOTION IN THE DENDRITIC SNOW GROWTH ZONE LATE TONIGHT. TEMPS
MAY HOLD STEADY IN THE N TONIGHT.

FAST MOVEMENT OF THE SYSTEM SHOULD LIMIT SNOWS TO A 9-10 HR PERIOD
LATE TONIGHT INTO WED AM. BUT THERE COULD BE DEFORMATION BANDS
THAT PUT DOWN AN INCH PER HOUR. THIS SHOULD MAKE IT EASY TO GET
INTO ADVSRY-TYPE NUMBERS OF 2-4 OR 3-5 IN THE NRN MTS. WILL POST
A WW ADVSRY FOR SNOW ACROSS THE NRN 2 TIERS OF ZONES. WILL NOT
BRING IT DOWN INTO THE I-80 CORRIDOR JUST YET...AS THAT MAY BE TOO
FAR SOUTH GIVEN THE PROJECTED PATH OF THE CENTER OF THE LOW. WINDS
WILL BE GUSTY AGAIN WED AS THE LOW GOES TO THE EAST. GUSTS COULD
AGAIN REACH ADVSRY CRIT IN THE SOUTH - ESP THE LAURELS...BUT WILL
HOLD OFF ON POSTING THE WIND ADVSRY FOR NOW.

NW FLOW PINS THE SNOW LATER WED AND WED NIGHT TO THE WRN
HIGHLANDS. GOOD UPSLOPE FLOW...-18C 8H AIR...AND A BIT OF A HURON
CONNECTION WILL COMBINE TO BATTLE THE ADVANCE OF THE SUBSIDENCE
INVERSION FROM THE WEST TO DETERMINE HOW LONG THE LAKE
EFF/UPSLOPE SNOWS WILL LAST. WILL CUT MOST SNOW OFF AFTER 6 PM
WED...BUT IT COULD CONTINUE FOR THE FIRST PART OF THE NIGHT. WILL
JUST PUT ANOTHER INCH OR TWO IN THE WEST AFTER THE CLIPPER PASSES.
BARELY A FLURRY SHOULD BE FALLING IN CENTRAL PA BY THE TIME THE
BALL DROPS. HIGHS SHOULD BE 5-10F BELOW NORMAL WED IN THE NW WITH
MORE CLOUDS AND SHSN...BUT CLOSER TO NORMAL IN THE SE.

HIGH PRESSURE BUILDS IN BY THURS MORNING AND LASTS ALL
DAY...PROVIDING FAIR WEATHER BUT HIGHS WILL BE 5-10F BELOW
NORMALS FOR NEW YEARS DAY OVER ALL THE REGION ON THURSDAY.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
NEW YEARS DAY SHOULD GET OFF TO A COLD START BUT PROVE TO BE A
MOSTLY SUNNY DAY. LATE AFTERNOON HIGH TEMPERATURES SHOULD REBOUND TO
NEAR NORMAL LEVELS.

FRIDAY SHOULD BE A MOSTLY CLOUDY TO CLOUDY DAY. A FAST MOVING SHORT
WAVE COULD BRING A DUSTING TO A FEW INCHES OF SNOW TO THE REGION.
THE WAVE IS TOO FAST MOVING AND NOW LACKS ANY SOUTHERN STREAM ENERGY
TO BE OF MUCH CONCERN. ADDITIONALLY...THE SURFACE WAVE PASSES TOO
FAR NORTH AND THE OLD RULE OF CLIPPERS SHOULD APPLY...YOU NEED THEM
TO PASS OVER OR TO YOUR SOUTH TO GET SIGNIFICANT SNOWFALL.

SATURDAY HIGH PRESSURE BUILDS IN SO IT SHOULD BE A SEASONABLE DAY
WITH MOSTLY SUNNY SKIES OVER MUCH OF THE REGION.

SUNDAY AND MONDAY SHOULD BE RELATIVELY QUIET DAYS...A SECOND HIGH
PRESSURE SYSTEM SHOULD DRIFT OVER THE REGION LATE SUNDAY INTO
MONDAY. THERE IS A VERY WEAK FRONT IN THE GEFS AHEAD OF THE SECOND
ANTICYCLONE WHICH COULD TRIGGER SOME FLURRIES.

TUESDAY...A SHORTWAVE IN WESTERN CANADA AND ANOTHER OVER THE
SOUTHWEST COULD PRODUCE A STORM...WHICH MAY MOVE INTO OUR REGION.
THIS INCREASES THE CHANCE OF SNOW OR SNOW/RAIN TUESDAY INTO
WEDNESDAY. LOTS OF UNCERTAINTY SO KEPT POPS IN THE 33 PERCENT
RANGE...ABOVE NORMAL BUT NOT TOO WET JUST YET. LOTS OF UNCERTAINTY
AND TIME TO ADJUST THIS FORECAST.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
IR IMAGERY INDICATES DRY AIR REMAINING DONWSTREAM OF THE
ALLEGHENIES ACROSS THE SUSQ VALLEY AIRFIELDS. CIGS WILL REMAIN AT
VFR THRU 00Z WED...THEN AS CLIPPER SYSTEM APPROACHES FROM THE NW
KBFD WILL SEE CIGS LOWER TO IFR BY 06Z AS MOISTURE POOLS EAST.
LATEST GUIDANCE BRINGS CLIPPER SYSTEM SLIGHTLY FURTHER SOUTH
ACROSS CENTRAL PA...WHICH FAVORS BETTER ACCUMS ACROSS NORTHERN PA
AIRFIELDS. EXPECT VSBYS AND CIGS TO BE DOWN TO IFR TEMPO LIFR BTWN
07-11Z...THEN CLIPPER WILL DEPART THE REGION WITH GRADUAL IMPROV
TO CIGS AS MOISTURE POOLS EAST TOWARDS NEW ENGLAND BY 18Z WED.

FLOW TURNS NORTHWESTERLY WED AFTN AND PRESSURE GRADIENTS
INCREASE...HINTING THAT AFT 18Z WIND GUSTS COULD BE STRONG. MIXED
LAYER FROM BUFKIT PROFILES AT MOST AIRFIELDS TAP
40-50KTS...HOWEVER NOT COMPLETELY SOLD THAT WE WILL COMPLETELY MIX
DOWN. WINDS WILL SLACKEN OFF ON THURSDAY AS HIGH PRESSURE SLIDES
EAST ACROSS THE CENTRAL APPALACHIANS AND EVENTUALLY OFF THE MID
ATLC COAST BY EARLY FRIDAY. FLYING CONDS WILL DETERIORATE FRI/SAT
AS ANOTHER CLIPPER LOW SLIDES SEWD THROUGH THE LWR GRT LKS...WITH
SECONDARY COASTAL DEVELOPMENT INVOF DELMARVA/JERSEY COAST.
