A fast-moving line of low-topped showers and thunderstorms raced northeast across eastern Pennsylvania during the early morning hours, producing localized wind damage. The convective line was associated with a sharp cold front which trailed a deep low pressure system moving through the eastern Great Lakes.

The episode as NWS CTP wrote it up.
A fast-moving line of low-topped showers and thunderstorms raced northeast across eastern Pennsylvania during the early morning hours, producing localized wind damage. The convective line was associated with a sharp cold front which trailed a deep low pressure system moving through the eastern Great Lakes.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS State College, PA wrote its last area forecast discussion before the first event at Nov 17, 12:25 AM EST, 1 hour 23 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 1225 AM EST WED NOV 17 2010 .SYNOPSIS... LOW PRESSURE WILL DEEPEN AS IT MOVES UP THE OHIO VALLEY TO THE EASTERN GREAT LAKES OVERNIGHT. WINDY CONDITIONS ARE EXPECTED ON WEDNESDAY AS THE DEEP LOW PRESSURE AREA MOVES INTO QUEBEC. A FAST MOVING SYSTEM WILL MOVE IN FROM THE WEST FOR THURSDAY AND MAY BRING LIGHT MIXED PRECIPITATION TO THE AREA. DRY WEATHER SHOULD PREVAIL FROM FRIDAY INTO WEEKEND WITH TEMPERATURES GRADUALLY RISING TO SEASONAL NORMALS OR EVEN SLIGHTLY WARMER THAN NORMALS. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... STILL WATCHING FOR THE POTENTIAL FOR LOW-TOPPED TSRA TO POTENTIALLY DEVELOP IN THE HIGH SHEAR ENVIRONMENT TO OUR SOUTH AND POTENTIALLY EFFECT SOUTH CENTRAL AND SOUTHEASTERN PORTIONS OVERNIGHT. SFC DEWPOINTS CONTINUE TO RISE OVER THE SOUTH AND SOUTHEAST WITH 60 DEGREE DEWPOINTS OR HIGHER OVER THE TIDEWATER REGION. CURRENTLY LOWER SUSQ RIVER VALLEY DEWPOINTS ARE CREEPING INTO THE UPPER 50S...SO IT CERTAINLY WOULD NOT BE A SURPRISE IF NOT TOPPED CONVECTION DEVELOPED VERY LATE TONIGHT OR OVERNIGHT AND MIXED DOWN SOME OF THE STRONG SOUTHERLIES STREAKING OVERHEAD. LATEST RADAR LOOP SHOWERS SCT TO NMRS SHOWERS OF LIGHT TO MODERATE INTENSITY ACROSS CENTRAL AND EASTERN AREAS...WHILE THE MOST INTENSE ACTIVITY RIDES NNEWD OVER WRN PA AT THIS HOUR ALONG THE EASTERN BORDER OF THE UPPER LEVEL DRY SLOT EXTENDING FROM EXTREME ERN KY NWD THROUGH EASTERN OHIO. HAVE BEEN WATCHING NCFRB EVOLUTION LAST SEVERAL HOURS AND SOME GUSTINESS ALONG IT IN PLACES LIKE KIDI (SFC WIND G29 KTS) MOST RECENTLY. SO FAR DOWNWARD MOMENTUM MIXING HAS BEEN LESS THAN SPECTACULAR...BUT REALLY EXPECT THIS TO CHANGE OVERNIGHT AFT 06Z WHEN UPR TROF AXIS LIFTS NEWD THROUGH SOUTHWEST INTO NORTH CENTRAL PA ACCORDING TO 00Z NAM. POST FRONTAL WESTERLIES INCREASE TO 55 KTS AT 850 MB ACROSS THE LAURELS BY 12Z WITH DEEPLY CHANNELED FLOW EXTENDING ALL THE WAY UP TO 500 MB. THUS...PREVIOUSLY ISSUED WIND ADVISORY LOOKS REALLY GOOD AT THIS TIME. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/... INSTABILITY STILL THE LACKING INGREDIENT IN THE BLENDER OVERNIGHT FOR SVR CONVECTION. WILL CONTINUE TO CARRY SCT TSRA WITH GUSTY WINDS IN THE S AND SE FOR THE NIGHT...BUT WILL NOT MENTION TORS POSSIBLE...SINCE THE PROB IS SO LOW. EHI DOES NIP OVER 0.5 UNITS. RAIN WILL BE SOAKING BUT NOT EXCESSIVE. QPF OF 1-1.25 LOOKS SOLID IN THE CENTRAL AND NE ZONES WITH SLIGHTLY LESS ELSEWHERE. MAIN STORY WILL BE THE GUSTY WINDS AS THE LOW CONTINUES TO MOVE NORTHWARD. WILL GO WITH A WIND ADVISORY FOR THE ENTIRE AREA WITH GUSTS EXPECTED TO GET 35 TO 45KT - ESP ON THE RIDGES. WIND PROFILES GET WELL-ALIGNED OUT OF THE WEST BY SUNRISE...AND GRADIENT WILL TIGHTEN TO ABOUT 10MB ACROSS THE CWA. THE GRADIENT SLACKENS IN THE AFTERNOON IN THE SW AND WED EVENING IN THE NE. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... WINDS WILL BE GUSTY EARLY...BUT WILL DIMINISH QUICKLY WITH LESSENING PRESSURE GRADIENT AS LOW PRESSURE CONTINUES TO LIFT INTO EASTERN CANADA. THERE WILL BE JUST A CHANCE FOR A RAIN OR SNOW SHOWER ACROSS THE NW MTNS WED NIGHT WITH NW FLOW. WEAK MID LEVEL WAVE BRINGS ANOTHER CHANCE FOR LIGHT PRECIP ON THU...MAINLY TO WESTERN SECTIONS. THEN HIGH PRESSURE BUILDS IN FROM THE TENNESSEE VALLEY FOR THE WEEKEND BRINGING MILDER WEATHER. WEAK BACK DOOR COOL FRONT LINGERS TO OUR NORTH BRINGING MORE CLOUDS TO THE NORTHERN MTNS...BUT SHOULD BE PLENTY OF SUNSHINE. WEAK COLD FRONT MOVES THROUGH ON SAT...BRINGING BREEZY YET DRY CONDITIONS. BROAD TROUGH FORMS OVER CENTRAL U.S. EARLY NEXT WEEK. LOW PRESSURE SLIDES NE INTO THE GLAKES BY TUE-WED...SPREADING SHOWERS BACK INTO PA FROM THE WEST. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... DEEP LOW PRESSURE AREA IS PASSING OVER LAKE ERIE AT MIDNIGHT...WITH THE OCCLUDED FRONT MOVING THROUGH CENTRAL PA. STATIONS BEHIND THE FRONT ARE QUICKLY IMPROVING TO VFR WITH A WIND SHIFT TO THE SSW. EXPECT MVFR/IFR CONDITIONS TO CONTINUE OVERNIGHT AHEAD OF THE FRONT. THE VFR OVER WRN AREAS SHUD GRADUALLY DIMINISH AGAIN TO MVFR AS COLD AIR BEGINS THE PROCESS OF DROPPING THE CEILINGS. ALONG AND AHEAD OF THE FRONT THUNDER IS POSSIBLE AS WE HAVE SEEN STABILITY ERODE SIGNIFICANTLY OVER THE COURSE OF THE EVENING. LLWS ALSO POSSIBLE AS WINDS OUT OF THE SOUTH ARE VERY STRONG JUST OFF THE SURFACE. MOST SITES WILL IMPROVE TO VFR WEDNESDAY AS THE SYSTEM FINALLY MOVES WELL NORTH AND EAST OF THE REGION. MAIN RESIDUAL EFFECTS WEDNESDAY WILL BE STRONG WEST-NORTHWEST WINDS AND THE POTENTIAL FOR MVFR AND SCATTERED SHOWERS OVER THE HIGH TERRAIN OF THE WEST AND NORTH. OUTLOOK... THU...LOW CIGS AND VSBY POSSIBLE IN SHRASN WRN/NRN MTNS. FRI-SUN...NO SIG WX EXPECTED. && .EQUIPMENT... BFD ASOS HAS SUFFERED A FAILURE. EL TECHS WILL RESPOND IN THE MORNING. UNTIL THEN THE OBSERVATION WILL EITHER BE PARTIALLY OR TOTALLY MISSING AND THE TAF NOT AMENDED. && .CTP WATCHES/WARNINGS/ADVISORIES...
