What happened
The episode as NWS PBZ wrote it up.
A retrograding upper level low continued to bring the threat for showers and thunderstorms on June 29th. However, with meager instability and shear, most storms were able to remain below severe levels, and only a few strong to severe wind gusts and toppled trees were reported. Despite this, a relatively stationary boundary did leave enough focus for some training thunderstorms that produced flooding over portions of Jefferson and Armstrong counties in Pennsylvania; two counties that had already experienced several days of heavy rain and flooding.
What forecasters said that day

Area forecast discussion, Jun 29, 12:59 PM EST, 4 hours 30 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 159 PM EDT SAT JUN 29 2013 .SYNOPSIS... A BROAD UPPER-LEVEL LOW PRESSURE SYSTEM WILL LINGER OVER THE GREAT LAKES INTO NEXT WEEK. PERIODIC DISTURBANCES WILL SUPPORT DAILY ROUNDS OF SHOWERS AND THUNDERSTORMS. && .NEAR TERM /THROUGH TONIGHT/... MUCH OF THE SAME THROUGH TONIGHT. NUMEROUS SMALL SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS THE REGION AMID MODESTLY UNSTABLE ATMOSPHERE. MINIMAL SHEAR AND INSTABILITY WILL KEEP SEVERE WEATHER RISK AT BAY. ACTIVITY WILL TAPER OFF THIS EVENING MUCH LIKE THE LAST FEW NIGHTS. FEW AREAS OF FOG ARE EXPECTED OVERNIGHT. MANNING && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... MODELS AGREE THAT UPPER LOW WILL SHEAR OUT SOMEWHAT BEING REPLACED BY ANOTHER CLOSED LOW TO THE WEST. THIS WILL HELP SHIFT THE DYNAMICS BACK FROM THE EAST COAST TO THIS PART OF THE WORLD. RETREATING SURFACE BOUNDARY WILL BRING GREATER MOISTURE INTO AT LEAST EASTERN PARTS OF THE AREA FROM THE SOUTHEAST TOMORROW AND TOMORROW NIGHT. HARD TO BELIEVE AT THE END OF JUNE THAT WE'LL BE SITTING UNDER AN 80+KT JET. INDIVIDUAL IMPULSES AROUND THE UPPER LOW WILL FORCE CONVECTION IN WAVES AS HAS BEEN ADVERTISED. CURRENT THINKING IS THAT WE'LL BE ABLE TO KEEP SOME OF THE INSTABILITY LIMITED WITH MORE CLOUD COVER. DEEP LAYER SHEAR RETURNS...BUT AGAIN DON'T SEE MORE THAN A STRONG STORM OR TWO ON SUNDAY. MONDAY IS A CHALLENGING DAY... BEST MID AND UPPER TROPOSPHERIC FORCING SHIFTS TO THE WEST AND NORTH WITH THE RETROGRADING UPPER LOW. SURFACE BOUNDARY LOOKS TO BE PLANTED ACROSS THE MIDDLE OF THE FORECAST AREA WITH PWATS AROUND 1.5 INCHES OR SO. LOW CONFIDENCE FORECAST FOR MONDAY...AND KEPT THINGS LARGELY UNCHANGED SAVE FOR SOME TWEAKS TO ADJUST FOR CURRENT SYNOPTIC THINKING. MANNING && .LONG TERM /TUESDAY THROUGH FRIDAY/... SAME OLE-SAME OLE WITH H5 LOW CONTINUING OVER CENTRAL OHIO VALLEY. LOW LEVEL MOISTURE FIELD IN PLACE AND...WITH CONTINUED COOL POOL ALOFT...EXPECT MORE DIURNAL ENHANCEMENT OF PRECIP. IN FACT...SURE LOOKS LIKE WE NEVER EXPERIENCE AN AIR MASS CHANGE. UPPER LOW GRADUALLY FILLS AND MOVES NORTHWARD BY END OF PERIOD AND EXTENSION OF BERMUDA HIGH THEN EXTENDS WESTWARD. CONTINUED CHANCE SHOWERS AND THE POSSIBILITY OF AFTERNOON OR EVENING THUNDERSTORM. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... CONDITIONS WILL BE MUCH LIKE THE LAST FEW DAYS AS SEVERAL UPPER LEVEL DISTURBANCES DROPPING THROUGH A LARGE UPPER LEVEL TROUGH BRING THE CHANCE FOR DIURNAL SHOWERS AND THUNDERSTORMS. WHILE MAINLY VFR CONDITIONS ARE TO BE EXPECTED...OCCASIONAL MVFR TO IFR RESTRICTIONS WILL BE POSSIBLE...ESPECIALLY IN THE HEAVIER SHOWERS/STORMS DURING THE DAY. OVERNIGHT SOME MVFR FOG COULD ONCE AGAIN OCCUR...ESPECIALLY IN LOCATIONS THAT RECEIVED RAINFALL DURING THE DAY. IFR FOG WILL BE MOST LIKELY AT SITES SIMILAR TO LAST EVENING...KFKL...KDUJ...AND KZZV. MORE OF THE SAME IS EXPECTED SUNDAY. W-SW WINDS LESS THAN 10KTS WILL CONTINUE THROUGH SUNDAY. OUTLOOK.../SUNDAY NIGHT THROUGH THURSDAY/... OCCASIONAL RESTRICTIONS IN DAYTIME SHOWERS AND THUNDERSTORMS AND OVERNIGHT FOG IS EXPECTED THROUGH MUCH OF THE PERIOD AS SEVERAL UPPER LEVEL DISTURBANCES CROSS THE REGION. && .PBZ WATCHES/WARNINGS/ADVISORIES...
