The episode as NWS CTP wrote it up.
High winds in the wake of a strong cold front toppled numerous trees and power lines across the Lower Susquehanna Valley. A few trees fell onto vehicles, with some people narrowly escaping serious injury. Measured wind gusts of 50 to 60 mph were reported on several ASOS observations. In addition, the high winds resulted in widespread power outages with thousands of customers affected. Minor structural damage was also reported.

NWS State College, PA wrote its last area forecast discussion before the first event at Dec 31, 6:46 AM EST, 1 hour 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 646 AM EST WED DEC 31 2008 .SYNOPSIS... SEVERAL ALBERTA CLIPPERS WILL PASS THROUGH THE REGION OVER THE NEXT FEW DAYS...BRINGING CHANCES FOR LIGHT SNOW AND GUSTY WINDS. IN BETWEEN THE CLIPPERS...HIGH PRESSURE WILL PROVIDE COLD AIR AND WEAKER WINDS. THE FAST WESTERLY FLOW ALOFT WILL MAKE IT DIFFICULT FOR ANY GOMEX MOISTURE TO BE PULLED THIS FAR NORTH. TEMPERATURES SHOULD STAY AT OR BELOW NORMALS FOR MOST OF THE PERIOD. && .NEAR TERM /THROUGH TONIGHT/... CLIPPER STARTING TO MAKE SNOW OVER THE NRN TIER NOW...BUT IT MAY BE LIGHTER THAN ORIGINALLY THOUGHT. IT IS SO DRY THAT IT HAS TAKEN A LONG TIME FOR THE PRECIP TO MAKE IT DOWN TO THE GROUND. WILL HOLD THE LINE WITH 2-4 INCHES ACROSS THE NRN TIER...BUT THAT COULD BE A BIT TOO MUCH. TEMPS ARE ACTUALLY WARMING AS THE LOW OVER NW PA DEEPENS AND HEADS STRAIGHT FOR UNV AND THEN FOR PHL. SOME 40S ARE SHOWING UP IN SWRN PA. WE SHOULD SEE TEMPS HOLD STEADY OR RISE A FEW MORE DEGS BEFORE THE LOW PASSES AND BRINGS IN THE NASTY WEST WINDS. PRESSURE RISES BEHIND THE LOW CENTER WILL BE EXTRAORDINARY - SOME 15MB/6 HRS. THIS IS HIGHLY ANOMALOUS AND IS ALWAYS INDICATIVE OF A VERY WINDY DAY. BUFKIT PROFILES FROM LOCAL MESO MDLS AND NAM12KM DATA ALSO PLAY UP A VERY GUSTY SCENE TODAY. MAX MOMENTUM TRANSFER FROM THE TOP OF THE MIXED LAYER WOULD BRING WIDESPREAD GUSTS TO 50 KTS ACROSS THE SRN TIER...ESP THE LOWER SUSQ LATE THIS MORNING AND THROUGH THE EVENING. WILL THEREFORE EXPAND THE WIND ADVSRY TO COVER THE REST OF THE CWA...AND UPGRADE THE ADVSRY IN THE LOWER SUSQ AND SCHUYLKILL CO TO A WARNING...AND ADD A FEW HOURS ONTO THE END OF BOTH. THE PATH OF THE LOW WILL KEEP THE HEAVIEST SNOW ALONG THE NRN TIER...TAPERING OFF VERY QUICKLY SOUTH/WEST OF A LINE FROM KUNV TO KSEG. SOME OF THE HILL TOPS IN COLUMBIA AND SCHUYLKILL COS COULD PICK UP 2 INCHES BY THE END OF THE MORNING. && .SHORT TERM /THURSDAY THROUGH FRIDAY/... LAKE EFFECT AND UPSLOPE KICKS IN AFTER THE LOW PASSES BUT IS SHORT IN DURATION. THE FETCH IS ALSO SHORT WHICH WILL HELP TO KEEP THE BANDS FROM REACHING TOO FAR INLAND AND MAKE IT DIFFICULT FOR THE SNOW TO PILE UP IN ANY ONE LOCATION. THE GUSTY WINDS WILL ALSO MAKE IT TOUGH TO MEASURE. WILL THEREFORE JUST EXTEND THE WINT WX ADVSRY FOR WARREN CO THROUGH 03Z...AND MENTION GUSTY WINDS AS WELL FOR THE LATTER HALF OF THE DAY. EXPECT THE UPSLOPE TO HELP THE LAURELS TO GET THEIR USUAL SHARE OF SNOW TOO...BUT WILL KEEP ACCUMS UNDER 3 INCHES. THE WORST SPOTS WILL BE THE WEST-FACING SLOPES AND HILL TOPS. THE WINDS WILL BE THE WORST OF THE WX TODAY. AS THE LOW DEPARTS AND DEEPENS OFF TO OUR EAST...THE WINDS WILL TRY TO FILL THE VOID. GUSTS UP TO 60 MPH ARE EXPECTED IN THE SE...AND 50 MPH ELSEWHERE. THE WORST WILL LIKELY BE THIS AFTN WHEN DEEP MIXING AND UNI-DIR SHEAR WILL ALLOW TRANSFER OF THE FASTER WINDS ALOFT DOWN TO THE SFC. SUSTAINED WINDS COULD EVEN BE 20-30 MPH. AS THE EVENING CONTINUES...THE WINDS WILL START TO SUBSIDE...AND THE LAKE EFFECT WILL ALSO DWINDLE. ONLY THE SNOW BELT/WARREN CO SHOULD SEE SNOW AFTER MIDNIGHT. MOST OF THE STATE SHOULD BE PARTLY CLOUDY OR EVEN CLEAR FOR MIDNIGHT ACTIVITIES...AS THE STRONG SUBSIDENCE CLEARS IT OUT THIS AFTN AND EVENING. TEMPS MAY GET CHILLY FOR THURS MORNING...BUT WINDS WILL NOT GO TOTALLY CALM AND THE WARM ADVECTION AHEAD OF THE NEXT SYSTEM WILL ALREADY START IN THE WEST...AND KEEP US FROM GETTING REALLY COLD. THE NEXT CLIPPER WILL ROLL IN LATER THURSDAY NIGHT AND LAST MOST OF THE DAY ON FRIDAY PER TIMING OF MOST OF THE LATEST MDLS. THIS ALSO LOOKS LIKE A WINDY AND MAINLY DRY EVENT...AS THE SFC LOW STAYS WELL TO OUR NORTH. KEPT LIKELIES IN THE NW FOR NOW...BUT COULD SEE THOSE DROPPING IF CURRENT TRENDS CONTINUE WITH THE NEXT FEW PKGS. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... 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 GFS/GEFS AHEAD OF THE SECOND ANTICYCLONE WHICH COULD TRIGGER SNOW SHOWERS OR LIGHT SNOW. THE GFS AND GEFS HAVE SHOWN SOME UNCERTAINTY WITH THIS SYSTEM. BEST GUESS IS THERE COULD BE PERIOD OF LIGHT SNOW SUNDAY OR EARLY MONDAY. AFTER MONDAY CONFIDENCE IN THE FORECAST ERODES. MOST ENSEMBLE PREDICTION SYSTEMS (EPS) SHOW A RIDGE OVER THE BAFFIN SEA BY SUNDAY. HEIGHT ANOMALIES OF 2-3 STANDARD DEVIATIONS ABOVE NORMAL OVER THE BAFFIN SEA AND BAFFIN ISLAND ARE CLEARLY VISIBLE. ADDITIONALLY...THE LOW TO THE SOUTH FORMS A NICE REX BLOCK. THE NCEP RMOP PAGE SUGGESTS THIS IS A HIGH CONFIDENCE FORECAST TOO. GREAT PATTERN FOR POTENTIAL EAST COAST WINTER STORMS (ECWS). BUT WE COULD MISS ANY SHORT-WAVES AT THIS TIME RANGE MOVING IN THE FAST FLOW OVER OUR REGION. BASED MOST OF FORECAST PACKAGE ON THE 0600 UTC GEFS AND 12Z MODELS. BUT THIS BLOCK SHOULD TREND THINGS COLDER OVER EASTERN NORTH AMERICA AND OUR REGION. THE 12Z GEFS IS CLEARLY COLDER. WITH THE BLOCK...IT SHOULD GET MORE DIFFICULT FOR STORMS TO TRACK OVER OR TO OUR NORTH. THE SOUTHERN STREAM STORM FORECAST IN THE TUE-WED TIME FRAME COULD HOLD MORE SNOW POTENTIAL...SHOULD IT DEVELOP. LOTS OF UNCERTAINTY AND THE EPS WE USE ARE ABOUT 100KM RESOLUTION SO ANY SIGNIFICANT SHORT-WAVES WOULD LIKELY BE MISSED. && .AVIATION /12Z WEDNESDAY THROUGH SUNDAY/... POTENT CLD FNT CROSSING CENTRAL PENN THIS MORNING...WITH BLUSTERY WINDS...FALLING TEMPS AND INTENSE SNOW SHOWERS IN ITS WAKE. THESE CONDS WILL CONTINUE INTO THIS AFTN ACROSS THE WEST/CENTRAL AIRFIELDS...WITH WINDS GUSTING 40KTS. SNOW SHOWER ACTIVITY WILL BE LIMITED FURTHER EAST...HOWEVER WINDS WILL BE STRONGER - GUSTING AS HIGH 50+MPH AT TIMES OVER THE LWR SUSQ VLY. XPECT LIFR/IFR AT JST-BFD...IMPROVING TO MVFR AND LOW END VFR/MVFR GOING VFR AT UNV/AOO/IPT. MDT SHOULD STAY VFR BUT EXPERIENCE SOME OF THE STRONGEST WIND GUSTS. PILOTS WILL HAVE TO DEAL WITH CROSSWIND AND TURBULENCE/LLWS TDY. WINDS WILL GRADUALLY SUBSIDE BY LATER TNT AS HIGH PRES MOVES IN FROM THE WEST. THE HIGH PRESSURE SLIDES SOUTH/EAST ACROSS THE CENTRAL APPALACHIANS ON THUR WITH VFR XPECTED. FLYING CONDS WILL DETERIORATE AGAIN FRI AS ANOTHER CLIPPER LOW SLIDES SEWD THROUGH THE LWR GRT LKS. THE PATTERN WILL TRANSITION TO MORE OF A CYCLONIC FLOW FOR SAT WITH ANOTHER POSSIBLE SYS FOR SUNDAY. && .CTP WATCHES/WARNINGS/ADVISORIES...
