The episode as NWS CTP wrote it up.
A narrow cold frontal rain band (NCFRB) crossed central Pennsylvania during the morning hours and produced isolated wind damage. The high shear/low cape environment was indicative low-topped convection along the sharp surface front, accentuated by pre-frontal south/southeasterly flow in excess of 50kts. Instability was the primary limiting factor concerning severe weather potential, with considerable warm-sector cloud cover inhibiting surface heating. The colder air aloft lagged behind the narrow convective band, which lead to weak low-mid tropospheric lapse rates and further reduced the potential for the strong low level winds/momentum from being transferred down to the surface. Precipitation loading was the primary mechanism for mixing down the strong low level winds, which seemed to be largely ineffective given the general lack of concentrated wind damage reports for this event.
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 Oct 7, 4:31 AM EST, 3 hours 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 531 AM EDT MON OCT 7 2013 .SYNOPSIS... A COLD FRONT OVER WESTERN PENNSYLVANIA WILL CONTINUE TO PUSH TO THE EAST AND SHOULD BE OUT OF THE AREA BY LATE AFTERNOON. TROPICAL MOISTURE AND HIGH WIND SHEAR WILL CREATE THE POSSIBILITY OF STRONG THUNDERSTORMS AND BRIEF HEAVY RAIN AS THE COLD FRONT MOVES THROUGH. HIGH PRESSURE IS EXPECTED TO RETURN FOR TUESDAY. A WEAK LOW PRESSURE AREA MAY DEVELOP TO OUR SOUTH DURING THE MIDDLE OF THE WEEK AND CRAWL SLOWLY NORTHWARD THROUGH THE SECOND HALF OF THE WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... CLOUDS NOW COVER MOST OF THE AREA...BUT RAINFALL JUST STARTING TO ENTER THE WESTERN HIGHLANDS. THE COLD FRONT SEEMS TO BE JUST AT THE LEADING EDGE OF THE RAIN. A STEADY PROGRESSION OF BOTH THE FRONT AND THE RAIN SHIELD WILL OCCUR THROUGH THE DAY. ALL MODELS IN VERY GOOD AGREEMENT RIGHT NOW. CONFIDENCE IS HIGH IN THE FORECAST TIMING. SREF RAINFALL AMOUNTS OF BETWEEN ONE AND ONE AND A HALF INCHES SEEMS REASONABLE. THEE DURATION OF THE RAIN SHOULD BE ABOUT 6 HRS...WHICH SHOULD KEEP ANY FLOODING WORRIES TO A BARE MINIMUM. SOME PONDING OF WATER IN THE NORMAL PLACES...BUT NOT EVEN SMALL STREAM FLOODING. MUCH OF THE AREA HAS BEEN QUITE DRY LATELY. THE MAIN FORECAST PROBLEM TODAY IS HOW UNSTABLE IT WILL GET OVER THE EASTERN HALF OF THE AREA THIS AFTERNOON. CLOUDS COVER THE AREA AT 5 AM AND DEEP SERLY FLOW AHEAD OF THE FRONT SHOULD ONLY REINFORCE THE CLOUD COVER. TEMPS MAY BE AT THEIR MAXES IN THE WESTERN HIGHLANDS...BUT THE EAST COULD HAVE 6-7 HRS OF POTENTIAL HEATING. THE COLD FRONT SHOULD BE PASSING THROUGH STATE COLLEGE ABOUT NOON/1 PM...AND HARRISBURG AROUND 2/3 PM. AREAS TO THE EAST OF THE FRONT WHICH CAN GENERATE SOME MODERATE INSTABILITY COULD HAVE SOME THUNDERSTORMS DEVELOP IN THE VERY STRONG SWRLY FLOW AHEAD OF THE FRONT. THE WINDS JUST 1-2KFT OFF THE GROUND WILL BE RACING AT 50KTS. IT WON/T TAKE MUCH TO MIX THAT DOWN...BUT THE CLOUDS WILL CUT DOWN ON HEATING WHICH WILL COUNTER-BALANCE THE THREAT. SPC DOES PLACE THE ERN HALF OF THE AREA INTO SLIGHT RISK. BUT THE LACK OF HEATING WILL BE THE TRICK. NAM MAKES LI AROUND -4 WITH TT AT 46 AND CAPE IN THE 1000+ RANGE AT MDT LATE THIS MORNING. SO A MENTION OF GUSTY WINDS IS AN EASY CALL...BUT MENTIONING SEVERE IS A BIT OF A STRETCH. CLEAR SLOT WILL LIKELY DEVELOP AFTER THE RAIN SHIELD MOVES TO THE EAST IN ALL LOCATIONS...BUT THE WNW FLOW BEHIND IT WILL LIKELY BRING CLOUDS BACK INTO THE NW/LAURELS THIS EVENING. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/... DRYING TAKES PLACE VERY QUICKLY AFTER FROPA. ALL PRECIP SHOULD BE TO THE EAST AT THE START OF THE PERIOD. SOME POST-FRONTAL COLD ADVECTION CLOUDS ARE POSSIBLE IN THE MOUNTAINS TONIGHT...BUT CLEAR SKIES EXPECTED ELSEWHERE. TEMPS WILL TAKE A TUMBLE INTO THE 40S TONIGHT...AND RIVER VALLEY FOG IS POSSIBLE. BUT THE WINDS WILL STAY UP FOR AT LEAST THE FIRST PART OF THE NIGHT. ANY CLOUDS WILL DISSIPATE ON TUESDAY...BUT SCT DIURNAL CU MAY DEVELOP UNDER THE COLD POCKET ALOFT AIR WITH HIGH AMBIENT MOISTURE FROM THE RAIN TODAY. 8H TEMPS DROP INTO THE LOWER SINGLE DIGITS BY TUES MORNING AND HOLD THERE FOR THE DAYTIME. MAXES WILL THEREFORE BE HELD TO THE 50S IN THE MOUNTAINS AND LOWER TO MID 60S ELSEWHERE THANKS TO THE DOWNSLOPE IN THE SERN HALF. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... HAVE TWEAKED WED NIGHT-THURS NIGHT TO REFLECT THE POSSIBLE EFFECTS OF A LOW SLATED TO DEVELOP TO THE SOUTH ALONG THE EASTERN SEABOARD. THIS COULD BRING SHOWERS UP INTO THE SRN/SERN PARTS OF THE AREA...AND HOLD TEMPS DOWN A BIT AS WELL. PREV DISCO... THE MODELS CONTINUE TO BE IN AGREEMENT WITH A NEARLY NEUTRAL TROUGH EXTENDING FROM THE LOW CENTER THAT CONTINUES TO MOVE NORTHWARD. COOLER AIR WILL ADVECT INTO THE REGION BEHIND THE FRONT MONDAY NIGHT...AS ANY LINGERING SHOWERS SHOULD BE GONE BY 06Z TUESDAY. THE PATTERN FLATTENS OUT QUICKLY TUESDAY MORNING AS SURFACE HIGH PRESSURE SETTLES IN FOR THE LONG HAUL ON TUESDAY. THE UPPER RIDGE RE-ASSERTS IT/S STRENGTH OVER THE ERN U.S. TEMPERATURES WILL BE COOLER THAN NORMAL ON TUESDAY...WITH MORE SEASONABLE TEMPS THROUGH THE REST OF THE WEEK. WITH THE DRY AIR AND SUBSIDENCE EVERY MORNING...IT WILL BE A CLASSIC SET-UP FOR VERY CHILLY MORNINGS. HOWEVER...THE ABNORMALLY HIGH 5H HEIGHTS...8H TEMPS OF 10 TO 12C AND THICKNESSES IN THE MID 560S WILL PRECLUDE ALL BE THE VERY COLDEST LOCATIONS FROM GETTING NEAR FREEZING AT NIGHT. THE COLDEST TIME FRAME WILL BE TUESDAY NIGHT/WED MORNING. FROST IS POSSIBLE ACROSS THE NORTH. RESIDUAL MOISTURE MOVING ONSHORE...ALONG WITH A WEAK SFC LOW COULD ALLOW FOR EASTERLY FLOW LATE THURSDAY INTO FRIDAY. THIS MOIST ONSHORE FLOW COULD BRING ISOLATED SHOWERS THURSDAY NIGHT THROUGH FRIDAY AFTERNOON TO THE LOWER SUSQUEHANNA VALLEY. THIS LOW PRESSURE SFC/ALOFT WILL CONTINUE TO DEVELOP OVER THE WESTERN ATLANTIC UNDER THE UPPER RIDGE AND WILL CONTINUE TO RETROGRADE INTO SATURDAY...BEFORE DRIFTING OUT TO SEA. HAVE SLIGHTLY INCREASED POPS IN THE SOUTHEAST DURING THIS TIMEFRAME. && .AVIATION /09Z MONDAY THROUGH FRIDAY/... VFR CONDITIONS ACROSS CONTINUE ACROSS WESTERN AIRFIELDS EARLY THIS MORNING AS REGION REMAINS IN WARM SECTOR...AWAITING ARRIVAL OF A COLD FRONT LATER THIS MORNING. CIGS AT SUSQUEHANNA RIVER VALLEY TAF SITES...MDT...LNS AND IPT HAVE FALLEN INTO MVFR RANGE AS GUSTY S/SE WINDS...WITH GUSTS PEAKING AT AROUND 25 MPH AT TIMES HAVE PUSHED MARINE LAYER FROM THE ATLANTIC OCEAN TO PUSH NORTHWESTWARD ACROSS CWA. EXPECT EXPANSION OF THE MVFR/IFR STRATOCU DECK AS NIGHT PROGRESSES. SCT SHOWERS WILL BECOME POSSIBLE IN THE VERY MOIST AIR OVER E PA AND THE SUSQ VALLEY AFTER 08Z AS LARGE SCALE LIFT BEGINS TO INCREASE...AND THESE SHOWERS ARE HINTED AT IN THE HRRR MODEL FORECAST. SO ADDED VCSH TO EASTERN TERMINALS OVERNIGHT. FOCUS THEN TURNS TO POTENT SFC COLD FRONT EXPECTED TO BE NEAR A KBFD TO KJST LINE BY 12Z...AND PUSHING STEADILY EAST ACROSS THE REST OF THE REGION DURING THE LATE MORNING AND EARLY AFTERNOON HOURS. A NARROW LINE /ABOUT 4 HOURS/ OF HEAVY SHOWERS/LOW-TOPPED TSRA SHOULD ACCOMPANY THE IMMEDIATE CFROPA...WHILE ISOLATED SUPERCELLS ARE POSSIBLE WELL TO THE EAST OF THE FRONT IN THE HIGHLY SHEARED ENVIRONMENT /MAINLY AFTER SUNRISE IN EASTERN SECTIONS/. THESE INDIVIDUAL CELLS WILL TRACK RAPIDLY TO THE NE AT 40 KTS PLUS. ANY OF THESE LEAD STORMS /OR THE EXPECTED LINE ALONG THE FRONT/ COULD MIX DOWN STRONG WIND GUSTS TO THE SFC. CONDITIONS IMPROVE FROM WEST TO EAST WITHIN A FEW HOURS OF FROPA AS PRECIP COMES TO AN END AND CEILINGS/VSBYS RETURN TO VFR FOR THE SECOND HALF OF MON /AS RIDGING BEGINS IN LOWER LEVELS/. WINDS TURN WESTERLY AND REMAIN AROUND 15 MPH GUSTING TO 25 MPH BEFORE DIMINISHING LATER IN THE DAY. CIG RESTRICTIONS LIKELY IN WESTERN/NORTHERN MTNS MON NIGHT AS COLDEST MID LEVEL AIR RETREATS TO THE NE AND LOW LEVEL SUBSIDENCE INVERSION SQUEEZES MOISTURE INTO A STABLE STRATOCU DECK. OUTLOOK... TUE...SCT AM SHOWERS/LOW CIGS POSSIBLE N AND W. WED-FRI...NO SIG WX EXPECTED. && .CTP WATCHES/WARNINGS/ADVISORIES...
